Not only do they share the same brand, the Oster French Door (TSSTTVFDDG) and the Oster 6 Slice (TSSTTVMNDG-SHP-2) are also both large digital convection toaster ovens. After we examined the most minute details, the slightly smaller Oster 6 Slice wins by a hair’s breadth. On a side note, the 6 Slice is also much cheaper.

The two toaster ovens have a similar number of design features but the Oster French Door stands out more and has slightly higher scores. The oven has a sleek brushed stainless steel design and a unique French door to separate it from the more common look of the 6 Slice.

However, the build does make the Oster TSSTTVFDDG harder to carry, especially when it doesn’t have carrying handles like the TSSTTVMNDG-SHP-2. Moreover, even though it has the largest cooking chamber among our tested toaster ovens, it only has two rack positions, not enough to make full use of the space.

The two are similar in terms of usability as well. Their control panels are of similar quality although the Oster French Door’s is more aesthetic. The Oster 6 Slice won because it was easier to clean, especially its guide rails and baking pan.

Performance was the decisive winning factor for the Oster 6 Slice. Despite its lower power draw, it had higher scores in almost all of our tests, including toasting bread, baking pizza, and fries, only losing slightly in roasting whole chicken. We suspected the Oster French Door isn’t powerful enough to accommodate such a large cooking space.

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.

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 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.

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.

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.

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.

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.

The Oster left a lot to be desired in baking french fries, thus scoring a 6/10.

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.

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.

Cooking Functions of the Oster XL Digital Convection Toaster Oven

Cooking Functions of the Oster 6-Slice Toaster Oven
The eight cooking functions of the Oster TSSTTVFDDG Toaster Oven are in the center of the control panel. They include Toast, Bake, Broil, Turbo Convection, Pizza, Warm, Defrost, and Dehydrate. The oven’s right side has air ventilation holes.
  • 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.

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 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.

The Oster TSSTTVMNDG-SHP-2 Oven’s cooking chamber has 4 nichrome heating elements, 2 guide rails, a light, and a fan cavity.

The Oster has four standard nichrome heating elements but only two tray levels—unlike the similar-sized Cosori CO130-AO that has three. In addition to a convection system, it has internal lighting which is always useful, especially when you can choose when to turn it on and off.

Capacity of the Oster Double Door Oven

Capacity of the Stainless Steel Oster Digital Countertop Toaster Oven
An opened front of the Oster TSSTTVFDDG XL Digital French Door Convection Toaster Oven on a white background. The cooking chamber is 15.75 inches long, 16.53 inches wide, and 10.04 inches high.
  • 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.

  • Height:
    9.4" (24.0 cm)

Its spacious interior can accommodate 6 slices of toast, a 12-inch pizza, and more than a 3 lb chicken. While the manufacturer didn’t state the exact capacity, we measured the cooking chamber’s volume to be around 28 liters.

  • 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.

  • Type:
    2-prong plug
  • Power:
    1300 W
  • Rated Output:
    120 V ~ 60 Hz

Since the power cord is positioned at the bottom of the oven, it may have some inconvenient bends. The length of roughly 25.98" is adequate for household use but not enough to wrap around the back buffers.

The rack fits perfectly with the guide rails and helps reduce the chance of an accident when you put food in the oven.

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.

  • Material:

  • Dishwasher Safe:

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.

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.

  • Height:

  • Material:
    Stainless steel
  • Dishwasher Safe:
    Not advisable

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.

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.

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.

User Control

6.0

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).

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.

Oster French Door Toaster Oven Ease of Use

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 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.

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.

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.
