Oster French Door vs Breville Smart Oven Pro Toaster Oven Side-by-Side Comparison
Our Verdict
- Performance (50%)6.4/10
- Design (25%)6.7/10
- Usability (25%)6.4/10
- Performance (50%)6.9/10
- Design (25%)9.3/10
- Usability (25%)8.0/10
The Oster French Door (TSSTTVFDDG) and the Breville Smart Oven Pro (BOV845BSS) are both large digital convection toaster ovens with similar prices. In the end, the Breville is the winner thanks to all the extra features it offers. The deciding factors have everything to do with design and usability, both of which the Breville scored higher.
The Breville has a slide-out crumb tray instead of the Oster’s removable type, a thicker casing for better heat insulation, and carrying handles on the side. Both units have internal lighting but the Breville has a non-stick interior and more tray positions.
The Oster’s french door is a very aesthetically pleasing design but it can slam shut if you slip. It only has the standard one oven rack and baking pan whereas the Breville has an extra broiling rack and pizza pan.
The Breville's control panel makes it easier to see the current settings for cooking mode, timer, and temperature. In addition to better button responsiveness, it also has dedicated toggles for converting temperatures, adjusting convection, and adding time to frozen foods.
With a higher power output and more powerful convection system, the Breville scored higher in almost all of our cooking tests, including toasting bread and baking pizza and fries. The only exception was the whole roasted chicken test where the Oster hit that temperature sweet spot to cook the chicken to a more desirable doneness.

Toast
- Function: Toast
- Number Of Slices: 4
- Toast Level: 4/6
- Cooking Time: 7m 25s
- Second Batch: 5m 31s
- Convection: No
We began our Toast test on the Oster with the default toast level 4 and got pretty good results right off the bat. For good measure, we continued to try the toast level 3, which failed to color evenly within the stipulated time.
We then tried level 5 only to end up with burnt toast and not the expected deep brown shade. Regretfully, while level 4 was the best toast level, it didn’t score high on our benchmark scale—only 6/10.
On this setting—7 minutes 25 seconds on the timer—the four pieces of bread on the upper tray were toasted to a nice golden brown color. However, the color became dark towards the edges, especially where the bread was less dense.
Additionally, a large portion of the bottom right piece of toast was significantly lighter, possibly indicating a cold spot in the cooking chamber. With such unevenness, we could only score the surface color a 6/10 despite the overall golden brown hue.
Moreover, due to the lengthy toasting time, the toast became very crispy but dry on the inside. Our head chef, Tuyet Pham, said this crispiness would be great for eggs benedict and especially soup, but maybe not omelets and sandwiches. Unfortunately, the dark edges produced a bitter taste, preventing it from getting higher than a 6/10 from our chef.
We toasted the second batch of four slices immediately after the first. We chose level 4 again whereupon the oven automatically calibrated the timer to 5 minutes 31 seconds.
Since the oven was already hot, the aforementioned cold spot became less apparent. The toast was not as crispy nor dry as the first batch, which made it more suitable for sandwiches and omelets.
However, the burnt edges were still a problem, so the oven received one final 6/10 for consecutive usability. If you want better results for the second batch, we recommend decreasing the toast level by one.
- Function: Toast
- Number Of Slices: 4
- Toast Level: 5/7
- Cooking Time: 5m 13s
- Second Batch: 3m 42s
- Convection: No
We began our Toast test by choosing toast level 4—the middle one out of the 7 options—for 4 pieces which we placed on tray level 2. The four pieces of bread came out only slightly toasted on top. We then chose level 5 and the surface color was more appetizing but less even.
So, we tried again one last time at level 6 but it produced four completely brown pieces of toast which were also a bit dry. In the end, we settled for level 5—5 minutes 13 seconds on the timer—as the best possible option with a score of 6.8/10.
At this level, the toast had a perfect golden brown color around the center of the oven. However, it was lighter the further it got to the rear, so we could only give it a 7/10 for even surface color.
The unevenness also translated to the texture where the toast achieved great crispiness in the golden brown areas but got softer in the lighter areas. This resulted in a 6.5/10 for taste from our chef.
Our head chef, Tuyet Pham, determined they would be good to have with omelets and sandwiches. They could be served with soups or eggs benedict but wouldn't make a perfect pairing.
We placed the second batch of four in immediately after the first one. We chose level 5 again whereupon the oven automatically deducted the timer to 3 minutes 42 seconds.
Because the oven was already hot, the second batch showed an increase in evenness for both surface color and crispiness deserving a 7/10. This batch would be more suitable for soups.
Pizza
- Function: Turbo Convection
- Temperature: 450°F
- Cooking Time: 6m
- Convection: Yes
For this pizza test, we didn’t choose the oven’s 400°F pizza preset because it didn’t match our Pizza test requirement of 450°F. Instead, we chose Turbo Convection as a suitable setting for baking pizza. Nonetheless, the results were not so favorable scoring only 6.4/10 on our testing scale.
We were, however, impressed that the oven only took 9 minutes to bake a 9-inch thick-crust meat pizza placed on the upper rack level. According to our accumulated data on average toaster oven performance, this deserved a 9/10.
Unfortunately, the oven lacks the high-intensity heating capability needed to crisp a crust effectively in such a short period of time, which the Toshiba AC25CEW-BS has. Consequently, parts of the crust bottom stuck to the grooves of the baking tray and the surface had a light golden color - so the score was only 5.5/10.
We had to stop baking because some of the meat and parts of the cheese started charring. It was a shame that the cheese didn’t completely melt before this, so we could only give the toppings a 6/10.
We were able to prevent the toppings from burning and the potential bitter taste. However, the crust and the topping weren’t good enough for the taste of the pizza to get a score higher than 5.5/10 from our chef.
- Function: Bake
- Temperature: 450°F
- Cooking Time: 4m
- Convection: Yes
For our Pizza test, we didn’t use the pizza presets because they didn’t include the correct size for our choice of pizza. This was also a good chance to test out the Breville pizza pan, but we were surprised to find the overall score ended up at 6.8/10.
Thanks to the oven’s strong power output and convection setting, it only took 4 minutes to bake a 9-inch thick-crust meat pizza placed on tray level 2. This was extremely fast and deserved a 10/10 according to our data on average toaster oven performance.
However, the pizza still had a problem with cooking evenness. A quarter of the entire crust was golden brown but the rest of it lacked color. As you can imagine, the golden brown part was crispy on the outside and soft on the inside while the lighter part was simply soft throughout. Thus, we could only give the crust a 6/10.
The same issue applied to the toppings which had a nice caramelization where the crust was golden but not much in the substandard area. The cheese was also not quite melty so the toppings also got a 6/10.
Altogether, our chef gave the pizza another 6/10 after tasting it. We chose not to increase the cooking time of the pizza as it could result in burning the part of the crust and toppings that were already properly baked.
Whole Roasted Chicken
- Function: Turbo Convection
- Temperature: 350°F
- Cooking Time: 1h 10m
- Convection: Yes
The spacious interior of the Oster seemed a key factor in our Whole Roasted Chicken test, scoring an impressive 8.1/10. We placed a 3 lb chicken belly-up on the upper rack level and flipped it after the first 40 minutes.
After 1 hour and 10 minutes, the skin reached an acceptable roasted color scoring a 7/10 for cooking time. Our chef surmised that further roasting wouldn’t result in better skin caramelization. Thus, we stopped roasting to avoid overcooking the meat and inadvertently lowering the total score.
The skin had an appetizing golden color, except for the sides of the two drumsticks which were a little lighter in color. Compared to other benchmark tests, the skin only crisped slightly indicating the heating elements and convection system to be less than ideal/top-of-the-range. The results were good, enough for a 7.5/10.
In conclusion, the oven maintained an ideal temperature long enough to evenly cook an entire chicken throughout. We measured the internal temperature of the chicken and it was 181°F. This was very surprising and almost spot-on with the recommended 165°F - 180°F by the USDA—thus earning a whopping 9.8/10 for doneness.
Interestingly, the meat came out so tender that the bone simply fell off as we tried to carve the chicken. If the skin was crispier, the chicken would have received a higher than 8/10 for taste.
- Function: Bake
- Temperature: 350°F
- Cooking Time: 1h
- Convection: Yes
For our Whole Roasted Chicken test, we placed a 3 lb chicken in a belly-up position onto the broiling rack and baking pan combo on tray level 1. The outcome was pretty satisfactory, scoring a 7.5/10.
The Breville took 1 hour to roast the chicken to a desirable color which was our standard for an 8/10. The skin overall had a golden color, especially at the wings and the tips. However, it still had some very light areas.
In addition, when we flipped the chicken after the first 40 minutes, some of the skin on the back of the chicken got stuck to the broiling rack. This was an indication that the skin was soft and didn’t crisp up much despite having the convection fan deployed. Thus, we gave the skin a 7/10.
The oven was able to maintain a good internal temperature so the chicken was cooked all the way through leaving behind no pink spots. However, the cooking time was a little long, so the chicken’s internal temperature ended up at 198°F which was higher than the recommended 180°F by the USDA. We gave the doneness of this chicken an 8.6/10.
Nonetheless, the meat wasn’t dry and combined with the skin it was enough to get a 7/10 for taste from our chef.
Baked French Fries
- Function: Turbo Convection
- Temperature: 400°F
- Cooking Time: 30 m
- Convection: Yes
For our Baked French Fries test, the Oster was disappointing, scoring only 4.1/10. Our reasoning was the poor size ratio of the cooking chamber to the oven’s power output. The oven wasn’t able to maintain a high enough temperature for baking frozen fries, as opposed to the Ninja DT201.
After 30 minutes the fries showed no significant change in color—where the test time limit was 25 minutes! Therefore, we had no choice but to stop baking and give the fries a 0/10 for cooking time.
Most fries had a pale color as if they were air-dried instead of air-fried. Some small pieces had a light golden color, but that wasn’t enough to score higher than 5/10.
Texture-wise, the fries were soft but dry on the outside, barely enough for a 5.5/10. All things considered, the only silver lining was that the fries were cooked, so our chef gave them a 5/10 for taste.
- Function: Bake
- Temperature: 400°F
- Cooking Time: 24m
- Convection: Yes
Despite the power draw of 1800 W, the Breville didn’t perform as well in baking french fries as many toaster ovens with the same output earning a 6.1/10. Looking at the results from the Ninja DT201, our assumption was that the broiling rack wasn’t as efficient for this purpose as an air fryer basket.
For our Baked French Fries test, we didn’t turn on the Frozen Foods toggle because we needed to keep track of the exact cooking time. The oven took 24 minutes to bake 12 oz of frozen fries on tray level 2 which wasn’t very fast. Compared to many other toaster ovens we’ve tested, it could only get a 6/10 for cooking time.
Even though we gave the fries a toss after the first 10 minutes, they still came out with uneven coloring scoring a 6.5/10. Most of the thinner fries had a pretty good golden color while most of the thicker ones had a much lighter color.
To the same degree, the fries had different textures throughout earning it a 6/10 for this testing component. The pieces with a golden color were crispy outside and soft inside while the lighter ones were mostly just soft all the way through.
With all of that in mind, our chef couldn’t give a score higher than 6/10 after tasting the fries.

The Breville toaster oven came in an eye-catching box but it was only secured with two foam pads. On the bright side, its accessories including a baking rack, baking pan, broiling rack, and pizza pan were neatly placed in a fitted carton box.
The oven’s user manual explains in detail how each oven function works and includes a number of recipes. To elevate your pizza party, you can opt for the optional pizza crisper, pizza stone, and bamboo cutting board.
Exterior
- Weight:16.8 lbs (7.6 kg)
- Length:21.5" (54.7 cm)
- Width:20.0" (50.7 cm)
- Height:12.8" (32.5 cm)
- Material:Stainless steel
- Color:Silver
- Door Handle:Cool-touch
- Tray Indicators:No
- Crumb Tray:Removable
Considering the Oster’s large size, ventilation slats on all sides are a big plus. (+3). At first glance, the most stand-out feature was the tempered glass french door with cool-touch door handles (+3).
It has a rear buffer to maintain a cool distance from the wall, but we thought it could be greater(+2). Additionally, while the oven’s leg stoppers are sturdy, they are rather small.
Our measurements of the oven’s footprints were 21.53" x 19.96" x 12.79" which matched closely with the manufacturer’s 22" x 19.5" x 13". On a side note, we weighed the oven and it was 16.75 lbs while the manufacturer stated the entire package to be 13.87 lbs.
- Weight:18.1 lbs (8.2 kg)
- Length:18.4" (46.7 cm)

- Height:10.8" (27.4 cm)
- Material:Stainless steel
- Color:Silver
- Door Handle:Cool-touch
- Tray Indicators:Yes
- Crumb Tray:Slide-out
An exterior feature that stood out to us on the Breville is its side-positioned carrying handles which double up as air ventilation holes for the convection system. We were also impressed by the indicators on the glass door that direct you to its three tray levels and many cooking functions.
The Breville has an interesting automatic eject feature for when the oven rack is in the middle guide rail. This is achieved thanks to a magnet in the corresponding position on the oven door.
Further attention to the design shows in the convenient slide-out crumb tray and strong base stands. The oven’s door handle is cool-touch and provides a good grip. Unfortunately, the back buffers are not long enough to create ample space between the back of the oven and the wall.
Our measurements of 18.39" x 15.94" x 10.78" for the oven pretty much coincided with the dimensions provided by the manufacturer—18.5" x 14.5" x 11". The 1.5-inch difference in width is probably because we took the door handle into account.

The Breville has 3 control knobs for function, temperature, and timer. Its five buttons include four toggles for temperature conversion, interior light, convection fan, and Defrost feature. The Start/Cancel button and the digital display both shine red when the oven’s cooking.
The LCD screen will display ‘E01’, ‘E02’, or ‘E05’ when there is a non-resettable issue with the appliance. When this happens, immediately unplug the cord from the wall outlet and call the Breville Customer Service Center.
The ‘E03’ shows up when the oven temperature exceeds its design limit. Should this occur, unplug your oven, allow it to cool for 15 minutes, then plug it back in.
The ‘E04’ appears when the room temperature is below the set minimum. If this happens, unplug the oven and move it to a warmer area.
Cooking Functions of the Oster XL Digital Convection Toaster Oven
- Toast (level 1-6)
- Bake (150°F-450°F)
- Turbo Convection (150°F-450°F)
- Broil (450°F)
- Pizza (400°F)
- Warm (150°F)
- Defrost (150°F)
- Dehydrate (150°F)
The Oster has eight cooking functions including Toast, Bake, Broil, Pizza, Warm, Defrost, Dehydrate, and Turbo Convection. Despite the name, Turbo Convection is basically Convection Bake—meaning this oven only has one convection level.
The standard Bake function and ‘Turbo’ Convection operate in the oven’s maximum temperature range, between 150°F to 450°F. The Toast function has 6 preset levels from Light to Dark, Meanwhile, the Pizza function is set to 400°F and Broil to 450°F—meaning neither can be adjusted.
The user manual recommends not to preheat the oven when using Defrost and Dehydrate. These two functions are set to 150°F—the lowest possible temperature —and cannot be adjusted. However, 150°F is a bit high compared to common dehydrators which operate at around 100°F.
For some reason, we couldn’t find the set temperature for Warm in the manual, but we measured the temperature to be 150°F.
- Toast (level 1-7)
- Bagel (level 1-7)
- Bake (1 minute - 10 hours)
- Roast (1 minute - 2 hours)
- Broil (300°F, 400°F, 500°F; 1 minute - 20 minutes)
- Pizza (6″-13″; Fresh/Frozen)
- Cookies (1 minute - 1 hour)
- Reheat (1 minute - 2 hours)
- Warm (1 minute - 2 hours)
- Slow Cook (2 hours - 10 hours)
The Breville has 10 cooking functions which make full use of its wide timer and temperature ranges. Functions that allow for the full adjustment of temperature (120°F - 450°F) include Bake, Roast, Cookies, Reheat, and Warm.
The Toast and Bagel functions have 1-7 levels which include predetermined timers for 1-6 slices. This toaster oven went the extra mile as most others don’t take the number of slices into account.
Meanwhile, the pizza function includes presets for sizes ranging from 6" to 13" along with fresh or frozen pizzas. The Broil function has three preset temperatures including 500°F, 400°F, and 300°F for up to 20 minutes.
The Slow Cook function has two settings: ‘LO’ with a timer of 4-10 hours and ‘HI’ with 2-8 hours; and you can further adjust the timer up and down while cooking. After the Slow Cook cycle finishes, this function automatically turns to Keep Warm at 175°F for up to another 2 hours.
Interior
- Heating Elements:3 nichrome
- Convection Fan:Yes
- Lighting:Yes
- Tray Levels:2
- Rotisserie:No
- Safety Hook:No
The Oster uses three nichrome heating elements with an unusual looped design for the upper heating element (+3). Most similar large-capacity ovens we have examined have four upper heating elements, two bottom heating elements, and a combined power draw of 1800 W.
However, the Oster has only one upper heating element which bends across and around the cooking chamber’s ceiling to cover the same area as would four. Since the power draw is divided equally between working heating elements, we speculated this design choice was to accommodate the oven’s lower power draw of 1500 W.
The TSSTTVFDDG claims to have ‘easy clean interior walls’. While they are not grease-proof, our cleaning test showed that the oven was, indeed, easy to clean (+1).
The convection fan is situated on the right side of the cooking chamber (+2). While the oven has an interior light, it’s fully automatic with no manual operation (+2).
Having only two rack levels, the oven doesn’t really require guides on the glass door (-1). The manual recommends using the upper rack position for toast and pizza, and the lower one for other foods. It’s worth noting that the rack guide rails are assembled parts and not hollowed out of the cooking chamber’s walls like many other toaster ovens.
The baking rack should not be slid into the lower rack slot with the baking tray attached to the bottom. This will result in direct contact with the bottom heating elements.
- Heating Elements:5 quartz
- Convection Fan:Yes
- Lighting:Yes
- Tray Levels:3
- Rotisserie:No
- Safety Hook:All three levels
The BOV845BSS has a non-stick interior coating which explains the black color. The black interior isn’t a problem though thanks to the oven’s interior light. When necessary, you can remove the glass cover to change the interior light bulb which is a G9 type, 25 W, 120 V.
Each of the three tray levels has a safety hook to prevent the oven rack from accidently sliding all the way out. However, only the bottom one is positioned further in, specifically for this purpose. The convection system, while quite powerful, is pleasantly quiet.
The Breville has five quartz heating elements that use infrared light to cook. Compared to the more common nichrome heating elements, these heat up and cool down faster while also being easier to clean and more energy-efficient but don’t last as long in terms of durability.
For this unit, each heating element has a safety guard to prevent direct contact with baking pans and trays. However, if grease splashes onto the heating elements while cooking, it’ll leave permanent stains.
Capacity of the Oster Double Door Oven
- Length:15.8" (40.0 cm)
- Width:16.5" (42.0 cm)
- Height:10.0" (25.5 cm)
According to the manufacturer, the TSSTTVFDDG can take 14 slices of toast and two 16-inch pizzas on its two racks. However, our hands-on testing proved it fits only 12 slices (6 per rack, each requiring at least 4.5 x 4.5 inches of space) or a 15-inch pizza. While it wasn’t clear what the maximum size for a whole chicken was, our tests indicated plenty of room for a 3 lb bird.
The manufacturer doesn’t state the interior capacity, but we measured the cooking chamber volume to be around 42.83 liters—our biggest number to date. However, we felt only two rack slots didn’t do justice to the oven’s capacity.
- Length:14.2" (36.0 cm)
- Width:13.0" (33.0 cm)
- Height:8.3" (21.0 cm)
The Breville’s cooking chamber has a capacity of 25 liters which is quite common among large toaster ovens. This was one of the rare occasions where the cooking chamber’s volume that we measured matched the manufacturer’s stated capacity.
Many large units can also fit 6 slices of toast but not all can fit a 13-inch pizza like the Breville. This oven can also fit a 9-cup muffin tray or a 4.16-liter Dutch oven.
Power Cord
- Length:25.8" (65.5 cm)
- Type:2-prong plug
- Power:1500 W
- Rated Output:120 V ~ 60 Hz
The power cord is 25.79" long which is enough for household use. However, it could be a bit longer since a toaster oven as large as the Oster requires at least 5 inches of clear space on all sides. The oven doesn’t have storage space for the cord like some ovens do.
- Length:3.3 ft (1.0 m)
- Type:3-prong plug
- Power:1800 W
- Rated Output:110 V - 120 V ~ 60 Hz
The power cord is roughly 39.37"—plenty of length for household use. It does protrude from the bottom of the oven though, which may create inconvenient bends.
Accessories
- Length:15.7" (39.8 cm)
- Width:16.1" (41.0 cm)
- Height:0.7" (1.8 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The Oster has two slightly different baking racks. One is the standard rack type, while the other has two supports below to slide the baking pan under.
- Length:14.1" (35.8 cm)
- Width:11.6" (29.5 cm)
- Height:0.3" (0.7 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The baking rack fits perfectly with the guide to prevent accidents when placing food in the oven and has a pattern to keep the baking pan on top of it in place.
Accessories
- Length:14.13
- Width:11.8" (30.0 cm)
- Height:1.1" (2.9 cm)
- Material:Stainless steel
- Dishwasher Safe:Not advisable
The baking pan has ridges and grooves for creating attractive roast markings and catching drippings. It also has wide edges for a firm fit on the baking rack supports, unlike some other designs we’ve seen.
However, it’s not big enough to fit into the rack rail guides and can only go on top of a rack or attached beneath. This means it doesn’t make full use of the oven’s capacity. In addition, the tray is coated, but not completely non-stick so prone to stubborn stains.
- Length:11.8" (30.0 cm)
- Width:11.8" (30.0 cm)
- Height:1.2" (3.0 cm)
- Material:Stainless steel
- Dishwasher Safe:Not advisable
The baking pan has a non-stick enamel coating. However, it’s not big enough to fit into the guide rails which means it can’t fully utilize the capacity of the cooking chamber.
Accessories
- Length:15.7" (39.8 cm)
- Width:12.5" (31.8 cm)
- Height:0.8" (1.9 cm)
- Material:Stainless steel
- Dishwasher Safe:Not advisable
A crumb tray is always a useful accessory to clean up pesky debris, especially with a large toaster oven like the Oster. Look out for crumbs falling onto the oven floor as you take out the tray. It’s quite a hassle to tilt the oven to get them out.
- Length:11.8" (30.0 cm)
- Width:11.8" (30.0 cm)
- Height:0.9" (2.4 cm)
- Material:Stainless steel
- Dishwasher Safe:Not advisable
The broiling rack fits perfectly on top of the baking pan and shares the same enamel coating. It has grooves and ridges to allow for air circulation around the food as well as holes to allow the grease from the food to drip onto the pan below.
Build Quality
The TSSTTVFDDG is light for its size and has a graspable rectangular shape making it easy to carry or position on a counter (+2). It also has a sturdy build and durable stainless steel casing (+4). The LCD is black while the numbers are yellow and the settings are red, making everything easy to see (+1).
Unfortunately, we found that the flat buttons often required some force to register (-1). Moreover, the door hinge could be firmer thus preventing the door from slamming shut.
The Breville has a sturdy build and is made from durable stainless steel. The oven has good heat insulation and a good convection system so the casing rarely gets hot to the touch—only after a long cooking time at a high temperature (>400°F).
Its LCD has a good color contrast, the control dials turn smoothly, and the buttons have good responsiveness. On another note, this unit doesn’t provide enough oven racks to make full use of the three tray levels and additional accessories.
Note: This product adheres to the California Proposition 65.

User Control
The Oster’s controls are easy to understand since what you see is what you get (+2). Therefore, the LCD doesn’t provide any extra information but it’s easy to read (+2).
The buttons have only a single function and are easy to tell apart(+2). Although the manual says you can press the Stop/Cancel button twice to turn off the oven, we weren’t able to do so (-1).
The temperature can be adjusted in increments of 5°F and the timer runs from one minute to six hours, which is quite impressive (+1). Time can be adjusted in increments of 1 minute up to 2 hours and in increments of 0.5 hours above 2 hours (+1).
To set up the clock, press the clock button once and the clock will flash. Then, use the arrow keys to set the hour and press the clock button again to likewise set the minutes. Finally, push the clock button or the start button to set the time (+1).
The timer of the Breville is specified by the minute. The temperature can be adjusted in 5°F/5°C increments by turning the knob slowly and in 10°F/10°C increments by turning the knob fast.
You can freely adjust the time and temperature while the oven is running but will need to press Cancel to change the cooking function. Keep in mind that this may repeat the automatic preheat phase if the temperature is lower than the manufacturer’s set point.
Regarding the extra unique features, the Temperature Conversion button is a nice touch for international users. The convection setting can be applied to almost all cooking functions except for Toast, Bagel, and Broil.
The Frozen Foods button adds a predetermined amount of time but only to the Toast, Bagel, Pizza, and Cookies functions. However, we didn’t find it very helpful since cooking time depends heavily on the food quantity and personal preference.
As for the extra cooking functions, the Pizza presets, with predetermined timers, aren’t very useful as they allow for temperature adjustment but don’t take the current temperature into account. The same goes for the Slow Cook function which has a predetermined temperature that isn’t stated in the manual.
According to our observation, the oven reaches and maintains at 325°F on both Low and High so we didn’t get the point of having two settings. In addition, these temperatures are quite high compared to more common slow cookers’ which are around 200°F on low and 300°F on high.
If you want to adjust the temperature for slow cooking in this oven, you can choose the Bake function for which the timer also reaches ten hours.
Oster French Door Toaster Oven Ease of Use
As you select a function, the corresponding icons will illuminate in the LCD screen. The TSSTTVFDDG has an automatic preheat phase which is only applicable for the Bake and Turbo Convection Bake functions (+1).
After setting the time and temperature, you then push start and the display will show PrE indicating the oven is in the preheating phase. You can bypass this phase by pressing the start button a second time.
Preheating takes roughly 5 minutes to around 300°F regardless of the temperature you set. You can readjust the time and temperature only after the preheating phase.
Interestingly, we found that the oven would return to preheat mode after adjusting the temperature until the new input temperature was reached and not just 300°F. This is also stated in the user manual.
The racks fit perfectly into the rail guides thus preventing accidents when placing food in the oven (+3). When the cooking cycle begins, the interior light will turn on automatically and then off when the cooking cycle ends (+2).
The french door and its cool-touch handle allow you to stay away from the heat wave when opening after cooking (+4). The doors are also single-pull which is very convenient. However, the doors cannot open partially and can slam shut if your hand slips (-2).
Unlike some ovens, opening the door doesn’t stop the oven or the interior light (-2). The oven casing can get very hot after long cooking times at high temperatures, so you should take care (-1).
When the cooking cycle finishes, the oven will beep once, switch off the heat, and return to the clock screen. It’s advised to unplug the oven after use.
The Breville has an automatic preheat phase for functions that allow for temperature adjustment as mentioned above. According to the manufacturer, this feature will preheat the oven to 75% of the input temperature before sounding an alert. However, our observation showed that it would always preheat to around 300°F taking about 4m 55s regardless of the input temperature.
Due to the eject feature mentioned above, keep in mind to open the door slowly to prevent the rack from sliding too far outward. The door can be kept partially open at an 80° angle to let food cool inside the oven. Doing this doesn’t stop the oven, unlike some others. Be careful as the door can slam shut if you slip while closing.
When the automatic preheat phase or the cooking cycle ends, the interior light will turn on and then turn off after 30 seconds, similar to when you press the light switch. Unfortunately, there’s no way to keep the light on indefinitely.
If not used for 10 minutes, the oven goes into standby mode until you press Start again. Nonetheless, it’s still advised to unplug the oven after use. Your customized setting will remain in the memory of the oven until changed or the oven is unplugged from the power outlet.
Cleanability
The stainless steel exterior of the Oster was very easy to clean (+2). Even though the interior doesn’t have a non-stick coating, there are no tricky nooks and crannies, so cleaning didn’t require much labor (+4).
After roasting a chicken, the baking pan accumulated some stubborn stains which we were able to remove even with a baking soda paste and water (+1.5). We were worried the grease could splash inside the fan cavity while cooking, but this was not the case.
Cleaning the Breville was extremely easy thanks to its stainless steel exterior and non-stick interior. There were some tricky nooks and crannies in the cooking chamber but luckily, there was minimal grease splashing after all of our tests.
The enamel baking pan and broiling rack sported some stubborn stains from the roasted chicken even after we washed them with dish soap. Nonetheless, we took care of them quite easily by brushing them with a paste of baking soda and water.
The slide-out crumb tray was also helpful for cleaning up the crumbs but we still had to tilt the oven to get all of the crumbs out.
