The match between the Toshiba AC25CEW-BS Digital Convection Toaster Oven and the Oster French Door Digital Convection Toaster Oven (TSSTTVFDDG) shows that the largest size doesn’t necessarily bring the best value. The Toshiba is smaller but with higher scores in all aspects and at a lower price.

In terms of design features, the Toshiba and the Oster pretty much go toe to toe. The Toshiba has side carrying handles and more air ventilation slats while the Oster has a unique French door and a thicker casing.

The Oster has more nichrome heating elements and an interior light while the Toshiba doesn’t. However, the Toshiba has a higher build quality shown in its more informative LCD and more responsive buttons. It also comes with a rotisserie kit that’s rare for its price range.

Both toaster ovens have the same power draw, so the Toshiba’s smaller cooking chamber actually allowed it to faster reach and better maintain the desired temperature. As a result, it scored better than the Oster in almost all of our performance tests except for roasting a whole chicken where the Oster ended up with just the right internal temperature.

Following the procedures of our Toast test, we determined that level 4—3 minutes 55 seconds on the timer—was the best option with the score of 7.3/10. The level 3 and 5, in addition to being lighter and darker than ideal respectively, had very uneven surface color.

The toast level 4 of the Toshiba produced four pieces with a light golden brown color but a few areas too light. Due to not having the convection fan running, the color was about 80% even and we could only give it an 8/10.

The first batch of toast was nicely crispy while soft and moist inside so we gave it a 7.5/10 for taste. Our head chef Tuyet Pham determined that it would be great to go with omelet and eggs benedict, as well as good for sandwiches. Although it may not be particularly good for soup, the second batch was.

The second batch was browner and crispier while still being moist so it got a 6.5/10. If you want the second batch to be the same as the first, remember to lower it by one level.

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.

The Toshiba baked a 9-inch thick-crust meat pizza evenly throughout in terms of doneness and color earning it a 9.1/10.

Even though the Pizza preset of the oven is 450°F for 10 minutes, it only took 5m15s to cook. It was really fast compared to the recommended 10 minutes on the label. In comparison to other toaster ovens in our Pizza test, it scored a 9.3/10.

The crust wasn’t dry and turned out a beautiful golden brown with some nicely charred spots. It deserved a 9.5/10. The cheese was also nicely melted and caramelized so it got a 9/10. After tasting, our chef gave the pizza an 8.7/10.

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.

Even though we chose a 3 lb chicken—in accordance with our Whole Roasted Chicken test—and despite the 4-pound claim on the label, it barely fit. In addition, there wasn’t enough space below to use the drip pan so cleaning up was a hassle.

Luckily, the fat from the chicken didn’t splatter too much inside the oven. Overall, the Toshiba scored a 7.8/10 for this test.

It took the oven 1 hour, the standard amount of time, to roast the chicken to golden brown so we gave it an 8/10.

The smooth rotation caramelized the chicken skin to a superb color while maintaining the juiciness of the meat. However, the skin wasn’t really crispy without convection so we only gave a 7/10.

The rotation also allowed the whole chicken to be thoroughly cooked in 1 hour with no pink spots. The internal temperature, however, was a bit too high at 207°F compared to the USDA recommended 165°F-180°F, so it got a 7.8/10.

Even though the chicken was cooked to slightly well-done, the meat was still moist and tender so our chef gave it an 8 for taste.

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.

The Toshiba did an acceptable job of baking 12 oz of french fries earning a 6.1/10.

Compared to other ovens in our Baked French Fries test, we had to cook the fries for 20 minutes so we could only give it a 5/10. Being baked on a tray and not in an air fryer basket, the fries lacked color resulting in a 6/10.

The fries only crisped up a little on the outside and were considerably moist inside so it’s another 6/10. Our chef gave the resulting fries a 6.7/10 for taste.

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.

One of the strongest points of the Toshiba AC25CEW-BS Toaster Oven is plenty of air ventilation — on two sides, the back, the bottom, and the top. It also has strong bottom stands and two buffers on the back to prevent the oven from being too close to the wall.

This was one of the few ovens where our measurements and the manufacturer’s completely coincided at 18.98" x 15.59" x 10.78". We do need to point out that we could see the internal circuits through the ventilation holes although we’re not sure if it affects the oven.

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.

Cooking Functions of the Toshiba Digital Toaster Oven

Cooking Functions of the Oster XL Digital Convection Toaster Oven
  • Toast (level 1-6, without convection)
  • Bake (150°F - 450°F, without convection)
  • Broil (150°F - 350°F, without convection)
  • Pizza (150°F - 450°F, with convection)
  • Cookies (150°F - 450°F, with convection)
  • Defrost (100°F - 180°F, without convection)
  • Reheat (150°F - 450°F, with convection)

  • Keep warm (100°F - 180°F, without convection)
  • Convection (150°F - 450°F)

One may argue that 10 cooking functions are too many but they are helpful for beginners in the kitchen. The Rotisserie and the Keep Warm functions are the two that stand out from the rest.

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 Toshiba has 4 nichrome heating elements and 3 tray levels which are standard for its size. This oven has a convection system which is always a plus but it doesn’t have an interior light like many other units of the same size, e.g, the Breville BOV845BSSUSC. It received an extra point thanks to its rotisserie socket and bracket.

The cooking chamber of the Oster TSSTTVFDDG Toaster Oven has one nichrome heating element on top and two on the bottom, two rack levels, a shining light, and a fan cavity on the right wall.

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.

Capacity

True to the description, it can fit a 12-inch pizza. However, it can’t fit 6 slices of toast or a 4-pound chicken but is big enough for 4 slices of toast or a 3-pound chicken.

We measured the cooking chamber’s volume to be 23.3 liters which was a bit different from the manufacturer’s provided capacity of 25 liters. However, it could just be a difference in measuring standards.

  • 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.

  • 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.

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.

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.

The crumb tray is a useful accessory — crumbs being quite a hassle to clean up. However, some still fell to the bottom of the oven as we removed the tray. Also, upon cleaning the crumb tray after the roasted chicken test, we found it showed signs of oxidation from catching the drippings.

The rotisserie kit does a fantastic job of securing the chicken thanks to the angle-adjustable 2-pronged forks. The structure of the forks, however, isn’t particularly strong leading to possible slight bending. Also, in the aftermath of the roasted chicken test, a screw of the rotisserie kit had rusted slightly.

The Toshiba AC25CEW-BS is quite robust while still relatively light and small. It also has more air ventilation holes than a number of other toaster ovens including the Instant Omni Plus 18L and Cuisinart.

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.

User Control

8.0

The Toshiba has 10 functions to choose from. However, the convection fan isn’t applicable to all of them. Nonetheless, you can always choose Convection, then set the desired temperature and time. The temperature can be adjusted in 10°F increments.

The large and detailed timer from one minute to two hours is a strong point of this oven. It’s also specified by the minute.

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).

Ease of Use

The oven door has a heat-resistant handle and tray-level indicators on the glass. The casing has good heat insulation and only gets too hot to the touch at 450°F.

The Toshiba doesn’t have an automatic preheat phase like many other digital models, e.g., the Instant Omni Plus 18L. The digital display automatically turns off after a period of no interaction. After the oven finishes cooking, you will hear a very clear beep similar to when you’ve just plugged in.

There’s no audio cue when you’re adjusting the knobs. Furthermore, if you need to readjust the setting during cooking, you have to press stop and repeat all the inputs. The only thing you can adjust during cooking is the timer.

It’s hard to keep the door partially open and there’s no internal lighting. Also, this oven doesn’t turn off upon opening the door, unlike some others.

Although the accessories fit well, removing the rotisserie kit from the oven can be a little tricky even with the lifter. With a little practice, however, it’ll become much easier.

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.

We cleaned the Toshiba following our toaster oven cleaning guide. Thanks to its internal and external coating and lack of difficult nooks and crannies, cleaning was pretty straightforward. In addition, enough space has been left between the heating elements and internal walls to facilitate cleaning.

Roasting a whole chicken with the rotisserie kit left some difficult stains on the ceiling but a paste of baking soda and water did the trick. One minor inconvenience was that some crumbs still fell onto the internal floor and we had to pick them up anyway.

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.
