The Oster French Door (TSSTTVFDDG) is an extra-large digital convection toaster oven while the Panasonic FlashXpress (NB-G110P) is a small digital toaster oven without convection. Thus, it’s no surprise that the first product is the winner. However, it may surprise you that their scores don’t differ as much as their sizes.

Both units have interior lights, crumb trays, and an interesting design quirk of their own. The Oster has a sleek brush stainless steel casing and a single-pull French door. Meanwhile, the Panasonic has a vintage-appliance-look and an auto-pull rack.

The Oster has intuitive buttons but they usually require quite a bit of force to register. The Panasonic has a few distinct cooking presets that are typical in a Japanese appliance but its timer and temperature range aren’t very detailed and expansive.

The Oster’s larger cooking chamber makes putting food in and out and also cleaning afterward easier. Meanwhile, the Panasonic’s auto-pull rack limits the space of its already-small cooking chamber.

Performance evaluation was where the interesting upset happened. Both ovens produced good results, but the Panasonic was better at most of the tests, including toasting bread, baking pizza, and fries. Despite having a higher power draw and a convection system, the Oster only scored higher than the Panasonic in roasting whole chicken.

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.

There were a few interesting things, though not necessarily good, about our Toast test for the NB-G110P. We first tried the middle toasting level—level 3—and the results were all burnt. Then, we decreased the setting to level 2 and the toast was no longer burnt. However, it was still dark for our standard.

Finally, we cranked it down all the way to level 1—around 2 minutes 20 seconds on the timer. This setting allowed us to achieve an acceptable outcome scoring a 6.1/10 in total. Of course, this meant that we only had a reference for the darker setting and not the lighter one.

On the toasting level 1, the four pieces of toast had a nice golden brown color around the center of the oven. However, the color got significantly lighter as it got to the edges. This unevenness was all the more apparent on the bottom side of the toast, so we gave it a 7/10 for even surface color.

Unfortunately, such a short cooking time wasn’t able to crisp up the toast, even the golden brown areas. Our head chef Tuyet Pham deemed the toast, at best, passable to go with sandwiches, omelets, and eggs benedict and awarded it a 6/10 for taste.

All the existing problems of the first batch became slightly worse in the second batch. The cooking time for the second batch at toasting level 1 was automatically adjusted to be slightly shorter—2 minutes 11 seconds.

For some reason, the color was less even on top—one piece of toast was only lightly toasted, one was golden, one was golden brown, and one was brown. Nonetheless, the bottom of the second batch was similar to the first.

While the golden brown and brown pieces were a bit crispier than the first four, they weren’t enough to get the consecutive usability score to higher than 5.5/10.

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.

Through our Pizza test, we noticed that the heating elements of the Panasonic NB-G110P seem to be very powerful. However, it wasn’t coupled with even heat distribution, which resulted in a 7.4/10 pizza score.

The toaster oven was able to bake a 9-inch thick-crust meat pizza in only 3 minutes. This was one of our fastest recorded cooking times, even faster than the powerful medium-sized Cuisinart TOA-60, and deserving a whopping 10/10.

However, such a short cooking time was only enough to cook the crust while not giving it any color at all. The silver lining in this was that the crust wasn’t dry, enough for a 6.5/10.

The toppings would have been quite appetizing if not for the burnt onions, bell peppers, and meat tips. Luckily, the high heat meant that the cheese was melty which garnered the toppings a 7.5/10.

Unfortunately, the burnt parts affected the taste quite badly with their bitterness. Thus, our chef could only give the pizza a 6/10 after tasting it.

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.

As we tried to fit a 3-pound whole chicken inside the Panasonic for our Whole Roasted Chicken test, the chicken grazed the hot upper heating element. This resulted in quite an impressive caramelization on the skin but also permanent stains on the heating element.

The lack of space for heat circulation was one of the main reasons behind the subpar score of 7.1/10. If you were to roast a chicken in this oven, we recommend cutting open the chicken or chopping it into pieces beforehand.

The Panasonic took 1 hour 10 minutes to roast the chicken, compared to the standard one hour, so it got a 7/10. We decided to stop the cooking at this point because our chef suggested that the skin wasn’t getting any more color and we didn’t want to overcook the chicken.

While the skin close to the upper heating element was nicely caramelized, the rest of it lacked color. It was also really soft, similar to being steamed, so we gave it a 6/10.

Checking with a meat thermometer, we found the chicken’s internal temperature to be 196°F-198°F which was quite high compared to the USDA’s recommended 165°F-180°F. Of course, the meat had no pink spots, so we gave it an 8.3/10.

As a result of the long cooking time, the meat was a bit dry. Interestingly, the soft skin was able to make up for the dry meat, enough for a 7/10 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 problem of powerful heating elements and uneven heat distribution in baking pizza repeated here in our Baked French Fries test. However, the score for the Panasonic’s baked french fries was lower, at 6.1/10.

We tried to give the oven the benefit of the doubt and stop the cooking at 25 minutes. This was the time limit of our test and equaled a 5/10. We decided to stop the cooking so as to not decrease the cooking time score any further despite the fries’ lack of color.

Even after baking for 25 minutes, only the smaller fries had a light golden color. The bigger and longer ones were only golden at the tips while the rest of them was basically white. Thus, we gave the fries a 6/10 for color.

The smaller fries had a bit of crispiness to them while the bigger and longer ones were just plain soft. Nonetheless, they weren’t dry, so we could still give them a 6.5/10 for texture.

With such subpar colors and textures, our chef could only give the fries a 6.5/10 for taste.

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.

The only thing standing out from the stainless steel casing is the slide-out crumb tray on the bottom to help with cleaning (+1). Keep in mind to push the crumb tray all the way in or there’ll be gaps.

The oven has two bumps on the back which act as back buffers but we think they could be longer (+2). The shape of the cool-touch door handle makes it easy to grab (+2).

Cooking Functions of the Oster XL Digital Convection Toaster Oven

Cooking Functions of the Panasonic NB-G110P FlashXpress 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.

Panasonic NB-G110P has 6 functions: Toast, Frozen Waffle, Reheat Roll, Frozen Pizza, Quick Reheat, and Frozen Hash Brown.
  • Toast
  • Frozen Waffle
  • Reheat Rolls
  • Frozen Pizza
  • Quick Reheat
  • Frozen Hash Brown

You can simply operate the oven by selecting a temperature and adjusting the timer which was what we did with our performance tests. Also, you can choose one of the six preset cooking functions including Toast, Frozen Waffle, Reheat Roll, Frozen Pizza, Quick Reheat, and Frozen Hash Brown.

The Shade Control includes five levels that are applicable to all the preset cooking functions. It’s quite common for Japanese models to have very specific cooking functions like these. How useful they are, however, is up to the user to decide.

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.

Despite having some uncommon interior features, the NB-G110P still suffers from common limitations of a small toaster oven. Its interior score ended up at 5/10.

The oven has two quartz and ceramic heating elements, one upper and one lower (+1). They use infrared light to cook which makes the process faster and more energy-efficient. Nonetheless, two heating elements may not distribute heat as evenly as four or more will do.

While not as durable, they cool down faster and are easier to clean. However, if grease splashes onto the heating elements while cooking, it’ll leave permanent stains.

The upper heating element is closer to the front of the cooking chamber while the interior light is closer to the back (+2). During cooking, the light automatically cycles on and off in sync with the heating elements which means you can manually turn it on but not off.

The oven has a mechanism to smoothly pull the rack halfway toward you as the door is opened (+1). However, this design choice meant that the cooking chamber only has one tray level instead of two which is more common in small toaster ovens (+1).

The cooking chamber has a coating for easy cleaning but it’s not 100% non-stick (+1). The oven doesn’t have a convection system to help with heat distribution, similar to many other small units (-1).

Capacity of the Oster Double Door Oven

Capacity
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.

  • Width:
    9.8" (25.0 cm)
  • Height:
    9.1" (23.0 cm)

We could fit 4 slices of toast, a 9-inch pizza but we could barely fit a 3 lb chicken inside the Panasonic. We measured the cooking chamber volume to be around 16.08 liters, slightly different from the manufacturer’s provided capacity of 15.52 liters.

Looking at our measurements of 11.2" x 9.84" x 9.05" compared to the manufacturer’s 10.2" x 9.8" x 4.1", we speculated they measured the height only from the baking rack to the upper heating element.

The baking rack has two hooks in the back to latch onto a horizontal rod in the middle of the cooking chamber and two hooks in the front to connect to the door. Opening the door will pull the baking rack and the baking pan on top of it halfway toward you to help keep your hands and fingers safe from the heat. Keep in mind that when the rack is removed, the door won’t be able to close tightly.

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.

The baking pan fits nicely on top of the baking rack to prevent accidents. It has a grooved surface which can give your food attractive roasting marks and catch the dripping better. It also has a coating but it’s not completely non-stick so you may need to watch out for some stubborn stains after a heavy roasting session.

An opened Oster TSSTTVFDDG XL Digital French Door Toaster Oven on a white background. Inside the cooking chamber, from the bottom up are one removable crumb tray, one baking rack, and one baking pan under another baking rack.

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 price of the Panasonic is partially reflected in its build quality score of 7/10. A small footprint doesn’t stop the oven from having a sturdy construction (+2). Its casing is made from thick durable stainless steel so the oven only gets hot to the touch after a long cooking time at a high temperature (>400°F) (+2).

With the way the control panel is positioned, the NB-G110P has less length and more height than most toaster ovens of the same size category. The entire oven is shaped like a square which could be beneficial for some kitchen space (+2).

The LCD is black and glows red creating good color contrast and the analog buttons are responsive and can last a long time (+2). One thing to be nitpicky about is that you need to pay attention to push the crumb tray all the way in or else the oven won’t be tightly sealed (-1).

User Control

7.0

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).

The control panel of the Panasonic wasn’t the easiest to use but it also didn’t cause any problem, so it earned a 7/10.

The current setting on the LCD is indicated by a red light which makes it easy to see (+2). Thanks to the light toggle, you can turn on the light even when the oven is not running (+2).

The preset cooking functions seem to be designed for worry-free cooking (+2). However, because they don’t allow for the adjustment of time and temperature, they weren’t applicable to our test.

Moreover, we couldn’t find the exact preset temperature and cooking time in the manual (-2). Thus, we simply chose to operate the oven by adjusting the temperature and timer on the control panel (+2).

The temperature is displayed in both °F and °C. It can be adjusted in increments of 35°F/20°C from 250°F to 500°F / from 120°C to 260°C, which is quite uncommon (+1). The timer can be adjusted in 0.5-minute increments below 10 minutes and 1-minute increments after 10 minutes (+1).

In addition to not having a stay-on feature, the timer only lasts from one to 25 minutes which is very short. It’s also worth noting that the timer is displayed in a 0.5-minute multiplier and not by the minute and second, unlike most other toaster ovens.

The cooking starts as soon as a timer adjustment key is pressed which makes it a bit tricky to get right. In addition, if you want to switch cooking functions, you’ll need to turn the oven off and on again (-1).

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.

Despite having some features of convenience, the Panasonic didn’t quite meet our standards and scored a 3/10.

In addition to the cool-touch door handle (+2), the auto-pull rack minimizes the risk of burning due to contact (+2). The oven rack can be a little awkward to remove but it’ll be no problem with a bit of practice (+2). However, the auto-pull mechanism means that the oven door can only open or close all the way and not open partially to let food cool inside (-2).

The manufacturer claims that this oven has a smart sensor that turns the heat on and off automatically to maintain the perfect temperature and prevent burning.  However, our tests showed no significant increase in terms of cooking performance compared to other small units.

It’s also advertised that this oven requires no preheating due to its efficiency. While we didn’t agree with this, we were able to confirm that the NB-G110P could reach a high internal temperature very quickly—4 minutes 50 seconds to reach 450°F.

The interior light makes it easier to make our way around the oven (+2). Keep in mind that opening the door doesn’t stop the oven or the interior light (-2). Be careful as the oven’s casing can get very hot after a long cooking time at a high temperature (-1).

When the cooking cycle finishes, the oven will beep once and then turn off. Nonetheless, we advise you to unplug the oven after use because, according to the manufacturer, the oven still consumes about 0.4 W when plugged in and not turned on.

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 Panasonic was quite easy to clean overall scoring a 6.5/10.

It has a stainless steel exterior and a non-stick interior (+4). The cooking chamber has no tricky nooks and crannies to make cleaning any more difficult than it needs to be (+2).

Thanks to the slide-out crumb tray, we could easily remove most of the falling debris after cooking. For the remaining crumbs on the cooking chamber’s floor, we could simply tilt the oven and get all of them out (+1).

Unfortunately, during our Whole Roasted Chicken test, the chicken grazed the upper heating elements when we put it in and left permanent black stains there (-1.5). The baking tray also suffered some stubborn stains but we were able to brush them off with a paste of baking soda and water (+1).
