The outcome of the match between the Breville Smart Oven Pro (BOV845BSS) and the Oster 6 Slice Convection Oven (TSSTTVMNDG-SHP-2) boils down to whether you want all the extra features or not. If you do, then Breville is the clear winner.

Both units are large digital convection toaster ovens, but the Breville has much higher scores in design and usability than the Oster. It’s worth noting that the former is also more than double the price of the latter.

Both toaster ovens have a slide-out crumb tray, but the Breville has a thicker casing for better heat insulation. They also have internal lighting but the Breville takes it up a notch with its non-stick interior coating for easy cleaning.

Looking at the control panel, the Breville displays the current settings for cooking function, timer, temperature more clearly. Its buttons respond better to inputs, not to mention the extra toggle switches for temperature conversion, convection settings, and frozen foods.

Cooking performance was where they tied. Both machines have equally good performance scores. However, we expected more from the Breville due to its higher power output. We suspected that its quartz heating elements might have suffered from inconsistency.

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.

Using the steps of our Toast test, we determined that level 2—6 minutes 43 seconds on the timer—was the best option, scoring a 6.2/10. In comparison, the toast at level 1 had a very light color, and the toast at level 3 had a dark brown color, with some dark patches.

The Toast Level 2 of the Oster produced four pieces with a golden brown color on the top. However, due to the unideal tray position, the toast was dark brown on the bottom. Even though the color was even, the big difference between the top and bottom resulted in a 6/10.

Due to the long cooking time, the first batch of toast was crispy outside but a bit dry inside, so it got a 7/10 for taste. Our head chef, Tuyet Pham, determined they would go well with eggs benedict, omelet, and soup, in particular, but not with sandwiches.

Even though this oven automatically deducted the toast timer to 4m 18s, the second batch was still significantly darker and drier. The color was also uneven, ranging from golden brown to dark, so it got a 5/10 for consecutive usability.

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.

The Oster did very well in baking a 9-inch thick-crust meat pizza, but the evenness in caramelization could be improved. Thus, it received an 8/10 in total.

It only took 6m 50s to bake the pizza as opposed to 10 minutes on the label. In comparison to other toaster ovens in our Pizza test, it got a solid 8.2/10.

The crust had a nice golden brown color and since it was neither too soft nor too dry, it scored an 8/10. The cheese was melty and the toppings’ caramelization was about 80% even, so we gave it another 8/10. For its taste, our chef gave the pizza one final 8/10.

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.

Thanks to the Oster’s large capacity, we placed a 3 lb chicken on top of its broiling rack which is then set on top of the baking pan before we perform our Whole Roasted Chicken test. The overall score was 7.8/10.

The oven was able to roast the chicken in 1 hour, which was the standard amount of time needed, and deserved an 8/10. Thanks to the broiling rack and the oven’s convection system, the skin got an even golden color throughout. However, even with those advantages, the skin wasn’t able to crisp up much, so it got a 7/10. 

The chicken was fully cooked, but its internal temperature was a tad high at 190-192°F, so we gave it an 8.8/10. The meat was soft and juicy throughout, so it earned a 7.5/10 for taste from our chef.

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 oven took 20 minutes to bake 12 oz of french fries. In comparison to other toaster ovens in our Baked French Fries test, it scored a 7.3/10.

The fries had an uneven color, ranging from almost none to golden and brown on the ends, so they got a 6.8/10. The fries were very soft so they could only get a 6/10 for texture. Our chef gave the fries a 5/10 for taste.

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 Oster has air ventilation holes on all sides of the convection system, which is a plus. In addition, having a slide-out tray is always helpful because it makes it easier to clean the oven.

Although the back buffers aren’t very sturdy, the bottom stands are and they also act as oven-carrying handles. Our measurements of the oven’s footprints were 19. 68" x 15.19" x 11.61" which were only slightly different in terms of width to the manufacturer’s provided  19.72" x 16.29" x 11.33".

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.

The built-in clock is something you rarely see in a toaster oven, but we’ve seen some comments about it, usually pointing out that the clock is ahead of time by 5 minutes.

Cooking Functions of the Breville BOV845BSS Smart Oven Pro

Cooking Functions of the Oster 6-Slice Toaster Oven
Breville BOV845BSSUSC has 10 cooking functions: Toast, Bagel, Bake, Roast, Broil, Pizza, Cookies, Reheat, Warm, Slow Cook.
  • 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.

The Oster TSSTTVMNDG-SHP-2 has 7 cooking functions including Toast, Bake, Convection Bake, Broil, Warm, Defrost, and Pizza.
  • Toast
  • Bake
  • Convection Bake
  • Broil
  • Warm
  • Defrost (150°F)
  • Pizza (400°F)

You can only adjust the temperature on the Bake and Convection Bake functions, which should be good enough for experienced cooks. Other functions have their temperature predetermined by the manufacturer, which can be useful for beginners in the kitchen. 

For some reason, the user manual doesn’t specify the predetermined temperature for the Warm function. Nonetheless, we were able to measure it to be around 180°F, which was unfortunately quite high for its purpose. Other toaster ovens with the Warm function usually maintain around 80°F-100°F.

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.

  • 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.

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.

The baking pan goes hand-in-hand with the broiling rack to catch the drippings and meat juice. Its enamel coating makes it more resistant to stains and caramelized bits but it is not advisable to put the baking pan in the dishwasher.

However, it’s slightly smaller than the oven’s capacity and therefore, does not make the most of the space. Nonetheless, it still does the job of preventing any hot mess from dirtying the heating elements which can lead to fire danger.

The broiling rack has an elevation from the baking pan to allow for heat circulation around the food. However, it’s not firmly attached to the baking pan, so be careful when you move this combo around. In addition, the rack doesn’t have a coating, which may make it prone to caramelized bits, stains, and discoloration.

Similar to the two above, the pizza pan has an enamel coating and can accommodate a pizza of up to 13 inches. It won’t be as effective as a proper pizza stone (which you can purchase) but is still a nice included accessory.

Build Quality

6.0
The front of an opened Breville BOV845BSSUSC Toaster Oven with a pizza pan, oven rack, enamel baking pan, and broiling rack.

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.

Though it is made from durable materials and has a sturdy build, the Oster isn’t heavy for its size. The digital display is clear, but the flat buttons can be irresponsive at times; this seems to be a common problem for Oster units, as the Oster TSSTTVFDDG also suffers from it.

Throughout the testing procedure, we found that the oven’s power output of 1300 W may have offset its large capacity. Our speculation was that its performance efficiency could increase with 1800 W.

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.

For the Oster, the temperature can be adjusted in increments of 10°F. The timer can be adjusted in increments of 30 seconds when it’s below 10 minutes and in increments of 1 minute after 10 minutes. The convection fan isn’t all-applicable, but you can adjust time and temperature according to your preference on Convection Bake.

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.

The Oster doesn’t beep with each press of a button which isn’t normally an issue. However, because the buttons weren’t always responsive, we had to check the display with each press and this required us to do so more than once.

One thing to keep in mind is that the oven requires you to press Cancel before changing the cooking function. After the cooking cycle finishes, the digital display will show END and the oven will sound 4 beeps 3 times. You’ll then need to press Cancel before performing further inputs.

The oven’s exterior only gets hot to the touch after a long period of cooking at a high temperature (> 400°F). The door can easily be kept partially open, but it doesn’t stop the cooking process, unlike some other ovens.

The built-in clock will keep ticking as long as the oven’s plugged in, but the power consumption should be minimal. Thus, it’s up to you to keep the oven plugged in or to remove it.

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.

The Oster has an internal and external coating. There are no tricky nooks and crannies. The slide-out crumb tray made cleaning up the crumbs very easy but we still had to tilt the oven to remove all of them.

Although some grease splashed inside the oven during our Whole Roasted Chicken test, we could easily clean it up using the instructions in our toaster oven cleaning guide. The baking pan, even with the enamel coating, sustained some stubborn burnt bits and stains that required brushing with a paste of baking soda and water.
