Cosori Air Fryer Toaster Oven vs Oster 6 Slice Convection Toaster Oven Side-by-Side Comparison
Our Verdict
- Performance (50%)8.0/10
- Design (25%)9.4/10
- Usability (25%)8.3/10
- Performance (50%)7.0/10
- Design (25%)6.2/10
- Usability (25%)6.6/10
The Cosori Air Fryer Toaster Oven (CO130-AO) and the Oster 6 Slice Convection Toaster Oven are both large digital units. The winner is clear as the first contender is our best-to-buy pick while the second is just an average unit.
Both toaster ovens have similar features including internal lighting and convection that can be toggled using their digital controls. However, the Cosori has a much higher build quality than the Oster throughout. Its digital display is more informative, its buttons respond better, and its automatic preheat phase reaches the exact input temperature.
Performance-wise, the Cosori has a higher power output to excel at all of our cooking tests, including toasting bread, baking pizza, roasting a whole chicken, and air-frying fries. The oven also has a rotisserie kit and an air-fryer basket to cover all the cooking tasks, unlike the Oster. The Oster still did well in all of the tests, not just as well as the Cosori.

Toast
- Function: Toast
- Number Of Slices: 4
- Toast Level: 2/7
- Cooking Time: 5m 49s
- Second Batch: 3m 50s
- Convection: No
We started our Toast test with four pieces of white bread. We ran the toast function at level 3. The results were good, but the color was a bit too brown to be ideal. After examining the outcome on level 2, it was clear that was the best option, earning a score of 7.6/10 in total. We also tried toasting at level 1, which resulted in lightly toasted bread, for reference.
At level 2, which automatically set the timer for 5 minutes 49 seconds, the four pieces of toast mostly had a beautiful golden brown color. However, the existence of lighter areas, especially on the bottom side, kept it from being perfect. We considered it worthy of an 8/10 for even surface color.
The taste deserved another 8/10 thanks to the toast’s crispy surface and soft, moist interior. Our head chef, Tuyet Pham, determined the toast would complement pretty much anything, including sandwiches, omelets, eggs benedict, and soup.
After the first batch of toast, we immediately placed the second batch in the oven. The toast level 2 program automatically reduced the time to 3 minutes 50 seconds to account for the last batch’s residual heat.
However, this seemed like too much of a reduction, since the toast came out mostly lacking in color. It wasn’t very crispy either, so we could only give the oven a 6.8/10 for consecutive usability.
- Function: Toast
- Number Of Slices: 4
- Toast Level: 2/6
- Cooking Time: 6m 43s
- Second Batch: 4m18
- Convection: No
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.
Pizza
- Function: Bake
- Temperature: 450°F
- Cooking Time: 3m 30s
- Convection: Yes
The Cosori’s ability to maintain a high temperature really shined in our Pizza test, garnering a score of 7.6/10.
With a high power output and powerful convection system, it only took 3 minutes 30 seconds to bake a 9-inch thick-crust meat pizza placed on tray level 2. This was extremely fast and deserving of a 10/10, the same as the Cuisinart TOA-60 which has the current highest pizza score.
However, the short cooking time resulted in uneven heating in the pizza crust and toppings.
While the bottom right quarter of the crust was golden brown, the rest didn’t have much color. Only that well-cooked part was crispy while the rest was soft, so we gave the crust a 7/10.
The same happened to the toppings. The bottom right quarter had a lot of caramelization—to the point that the onions even charred—while the rest was only mildly caramelized. In addition, the cheese wasn’t very melty, so we gave the toppings a 7/10 as well.
Taste-wise, our chef said it would be better if it weren’t for the slight bitterness from the charred onions. She gave the pizza another 7/10.
- Function: Bake
- Temperature: 450°F
- Cooking Time: 6m 50s
- Convection: Yes
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.
Whole Roasted Chicken
- Function: Rotisserie
- Temperature: 350°F
- Cooking Time: 40m
- Convection: Yes
We’ve conducted our Whole Roasted Chicken test a great many times, and the Cosori wasn’t the only one with a high power output and powerful convection system. What set it apart was its rotisserie kit and function.
In addition, the large cooking chamber had more than enough space for a 3 lb chicken to rotate smoothly with a baking pan below to catch the drippings, unlike the Instant Omni Plus 18L. Everything together scored a whopping 8.9/10.
The oven took only 40 minutes to roast the chicken to a beautiful color. That was the fastest time we’ve had so far, earning it a perfect 10/10. The skin was mostly golden with some appetizing golden-brown color at the wings and the tips.
However, it seemed like the skin cooked a bit too quickly and the fat wasn’t fully rendered, so the skin wasn’t very crispy. Nonetheless, the skin still deserved an 8.5/10.
What impressed us most was the near-perfect doneness—9.9/10—in such a short amount of time. The chicken had no pink spots and a consistent internal temperature of 178°F-181°F. It was basically spot-on to the USDA’s 165°F-180°F recommendation.
Unfortunately, for some reason, the meat wasn’t as juicy as we had expected. Combined with the less-than-crispy skin, our chef couldn’t give the chicken a higher score than 8/10 after tasting it.
- Function: Bake
- Temperature: 350°F.
- Cooking Time: 1h
- Convection: Yes
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.
Baked French Fries
- Function: Bake
- Temperature: 400°F
- Cooking Time: 17m
- Convection: Yes
The Cosori took on our Baked French Fries test with its air fryer basket and scored an 8.1/10.
It took 17 minutes to bake 12 oz of frozen fries on tray level 2—quite fast compared to most. After comparing it with other units from our data, we gave it an 8.4/10 for cooking time.
The fries mostly had a great golden color with some of the thinner pieces looking the most appetizing. However, some thicker pieces weren’t as golden, so we gave the fries an 8/10 for color.
The same can be said about the texture of the fries, which earned another 8/10. Most of the fries were crispy on the outside and moist on the inside, but the thinner ones were a bit dry and the thicker ones weren’t crispy enough.
Overall, though imperfect, the fries were delicious enough to get one final 8/10 taste score from our chef.
- Function: Bake
- Temperature: 400°F
- Cooking Time: 20 m
- Convection: Yes
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.

During our assessment, a prominent aspect of the Cosori toaster oven is the air ventilation holes on all sides of the casing to accommodate its powerful convection system. In addition, the glass door has indicators corresponding to the oven’s three tray levels and twelve cooking functions.
The oven doesn’t have carrying handles but it’s not heavy for its size so it’s not a big problem. Our measurements of 19.96" x 17.32" x 12.6" pretty much aligned with the manufacturer’s 20.1" x 16.5" x 12.5" with marginal differences being less than one inch. The difference in width is probably because we took the door handle into account.
- Weight:12.1 lbs (5.5 kg)
- Length:19.7" (50.0 cm)
- Width:15.2" (38.6 cm)
- Height:11.6" (29.5 cm)
- Material:Stainless steel
- Color:Black
- Door Handle:cool-touch
- Tray Indicators:No
- Crumb Tray:Slide-out
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 Oster has an LCD digital display and 15 buttons, including 8 functions, 2 to adjust time, 2 to adjust temperature, a light toggle, a clock feature, a stop and a start button. 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
- Toast (level 1-7)
- Bagel (level 1-7)
- Pizza (150°F - 450°F, 1 minute - 6 hours)
- Bake (150°F - 450°F, 1 minute - 6 hours)
- Roast (150°F - 400°F, 1 minute - 6 hours)
- Air Fry (150°F - 400°F, 1 minute - 6 hours)
- Broil (150°F - 450°F, 1 minute - 6 hours)
- Cookies (150°F - 450°F, 1 minute - 6 hours)
- Rotisserie (150°F - 400°F, 1 minute - 6 hours)
- Dehydrate (100°F - 180°F, 30 minutes - 24 hours)
- Ferment (80°F - 110°F, 30 minutes - 12 hours)
- Warm (140°F - 230°F, 1 minute - 12 hours)
Besides the basic cooking functions, which already have a wide time and temperature range, the Cosori air fryer toaster oven also has various practical additional cooking functions allowing for even wider time and temperature ranges.
The ones that impressed us the most were Warm, Dehydrate, and Ferment which can maintain the oven at as low as 140°F, 100°F, and 80°F respectively. Looking at a number of recipes, these temperatures fit their intended purpose, which means this oven can act as a family-sized dehydrator and dough proofer.
Note that only the bottom heating elements operate during these functions.
- 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.
Interior
- Heating Elements:4 nichrome
- Convection Fan:Yes
- Lighting:Yes
- Tray Levels:3
- Rotisserie:Yes
- Safety Hook:No
The interior features include a convection fan, light, a rotisserie socket and bracket, three tray levels, and four nichrome heating elements. To be nitpicky, we think it’s a shame it doesn’t have a non-stick coating, so it may accumulate some stubborn stains.
- Heating Elements:4 nichrome
- Convection Fan:Yes
- Lighting:Yes
- Tray Levels:2
- Rotisserie:No
- Safety Hook:No
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 Cosori XL 12-In-1 Air Fryer Toaster Oven
- Length:14.2" (36.0 cm)
- Width:13.8" (35.0 cm)
- Height:9.8" (25.0 cm)
The Cosori has a spacious cooking chamber even compared to other large ovens. It can accommodate 6 slices of toast, a 13-inch pizza, or a 5-pound chicken.
We measured the volume to be around 31.49 liters compared to the manufacturer’s listing of 30 liters. The difference is minor and could just be a difference in measuring standards.
- Length:14.2" (36.1 cm)
- Width:12.6" (32.0 cm)
- 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.
Power Cord
- Length:40.9" (104.0 cm)
- Type:3-prong plug
- Power:1800 W
- Rated Output:120 V ~ 60 Hz
The power cord has plenty of length for household use—roughly 40.94 inches. It protrudes from the bottom of the oven, unfortunately, so it may create awkward kinks now and then.
- Length:26.0" (66.0 cm)
- 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.
Accessories
- Length:14.2" (36.0 cm)
- Width:13.4" (34.0 cm)
- Height:0.3" (0.7 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The baking rack fits perfectly onto its guide rails to prevent accidents when placing food in the oven. It’s also shaped to maximize the space inside the cooking chamber.
- Length:14.2" (36.1 cm)
- Width:15.0" (38.1 cm)
- Height:0.2" (0.5 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The rack fits perfectly with the guide rails and helps reduce the chance of an accident when you put food in the oven.

- Length:14.2" (36.0 cm)
- Width:11.8" (30.0 cm)
- Height:1.2" (3.0 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The baking pan also fits the guide rails to fully utilize the cooking space. It has ridges and grooves which can give your food attractive roasting marks and allow drippings some space to flow away. Its coating isn’t completely non-stick, so it may gather some stubborn stains, though.
- Length:12.9" (32.7 cm)
- Width:10.5" (26.7 cm)
- Height:1.2" (3.0 cm)
- Material:Stainless steel with enamel coating
- Dishwasher Safe:Not advisable
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.
Accessories
- Length:14.0" (35.6 cm)
- Width:12.0" (30.5 cm)
- Height:0.8" (2.0 cm)
- Material:Stainless steel

The crumb tray is a helpful accessory to clean up the pesky falling crumbs and bits. However, some may still fall to the oven’s floor as the tray is removed.
- Length:10.9" (27.7 cm)
- Width:8.5" (21.7 cm)
- Height:1.2" (3.1 cm)
- 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.
Accessories
- Length:13.8" (35.0 cm)
- Width:13.2" (33.5 cm)
- Height:1.3" (3.3 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
With angle-adjustable 2-pronged forks, the rotisserie kit does a fantastic job of securing the chicken. The forks are made from thick steel so they won’t bend. They don’t have a coating, though, so they may be subject to permanent stains. The rod and the lifter, however, have a coating so you won’t need to worry about rust.
Accessories
- Length:14.2" (36.0 cm)
- Width:11.7" (29.8 cm)
- Height:1.2" (3.0 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
Similar to the baking pan and the oven rack, the air fryer basket fits the guide rails. In this case, however, it’s intended to provide space and allow for heat circulation around the bottom of the food.
Build Quality
The Cosori is made from high-quality and durable 304 stainless steel. The thick casing provides good insulation in addition to a well-thought-out convection system. Thus, the oven only gets hot to the touch after a long cooking time at a high temperature (>400°F).
As for the control panel, the LED display is very easy to see, the control dials turn smoothly, and the buttons are responsive. The accessories are designed to make the most out of the cooking chamber’s interior space.
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
The convection feature can toggle between normal and high, and neither setting makes much noise. The fan can run on all functions except Toast and Bagel.
Since time and temperature are controlled by a single dial, you must toggle between functions. Press the dial’s face to switch between them. Temperature can be adjusted in increments of 5°F or 2°C-3°C.
The timer, however, has different steps depending on the cooking function. For Pizza, Bake, Roast, Air Fry, Broil, Cookies, Rotisserie, and Warm functions, the timer can be adjusted in increments of 1 minute until it reaches 60 minutes, then in increments of 5 minutes from 1-2 hours, in increments of 10 minutes from 2-3 hours, and in increments of 15 minutes from 2-3 hours. For Dehydrate and Ferment functions, the timer only adjusts in increments of 30 minutes.
On top of the many practical cooking functions, the ease with which you can adjust time and temperature makes this oven, overall, simpler to use than many other digital ones. In addition, you can press and hold the time and temperature dial to turn off the display to save energy while you’re not cooking.
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.
Ease of Use
The Cosori has an automatic preheat phase which engages for the Pizza, Bake, Roast, Broil, Cookies, and Air Fryer functions. If the oven’s already hot, the function will recognize that fact and reduce its preheating time.
This toaster oven is one of the rare units that actually preheat to the input temperature. Most others simply heat to a hardwired preheat temperature that cannot be adjusted.
According to our observation, the Cosori takes around 2-4 minutes to reach 300°F, 3-5 minutes for 325°F, 4-6 minutes for 350°F, and 6-8 minutes for 400°F. When preheating is finished, the oven will beep several times and the display will flash once every minute. You’ll need to press start to initiate cooking or the cooking function will be canceled after 10 minutes.
Thanks to the light toggle button, you have full control over when to turn the light on and off. The door can rest open at a 70° angle to allow food to cool inside the oven. Opening the door doesn’t stop the heating elements or the interior light.
The oven turns off automatically after 30 minutes of no interaction. Nonetheless, we still suggest unplugging it after use for safety reasons.
The Cosori’s EvenRapid Tech™ is advertised to reduce cooking time by 30% thanks to increased heat circulation. Suffice to say, it met our expectations with fast cooking times and even surface caramelization (except on our Pizza test).
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.
Cleanability
The Cosori’s exterior and interior are made of stainless steel, so they’re usually easy to clean. However, the interior doesn’t have a non-stick coating, so the grease from our whole roasted chicken test led to some extremely stubborn stains on the cooking chamber’s ceiling. We couldn’t completely remove them even after brushing them with a paste of baking soda and water.
The rotisserie forks and rod as well as the rotisserie bracket and the baking pan developed equally stubborn stains. On the bright side, it wasn’t difficult to clean caramelized bits of food from the air fryer basket despite the fishnet design.
The grease on the other walls and around the fan cavity was easy to clean. We were worried that grease might splash into the fan cavity, though.
We were able to easily remove fallen food scraps thanks to the removable crumb tray. However, we still had to tilt the oven to get them all 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.
