Cosori Air Fryer Toaster Oven vs Hamilton Beach 31127D Countertop Side-by-Side Comparison
Our Verdict
- Performance (50%)8.0/10
- Design (25%)9.4/10
- Usability (25%)8.3/10
- Performance (50%)6.6/10
- Design (25%)5.2/10
- Usability (25%)6.4/10
The Cosori Air Fryer Toaster Oven (CO130-AO) completely mopped the floor with the Hamilton Beach 31127D Countertop Toaster Oven. Nonetheless, the Hamilton is still a solid choice if you want an inexpensive medium-sized unit that doesn’t have convection.
Design-wise, the Hamilton has a good overall build quality encompassing its roll-top door that moves out of the way while you bring food in and out of the oven. Its control dials are also very precise for being analog.
The Cosori, on the other hand, has an intricate control panel with an informative digital display, intuitive buttons, and toggle switches for convection settings, lighting, and temperature conversion. On top of a larger capacity, these features, of course, make the Cosori cost more than the Mueller.
Performance was what really separated the Cosori—our best-to-buy pick—from the Hamilton. Thanks to its convection system and higher power draw, the Cosori consistently produced top-tier results in toasting bread, baking pizza, roasting whole chicken, and air-frying fries. The Hamilton’s foods were above average and thus, couldn’t compare with 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: 3/4 to Medium
- Cooking Time: 3m 30s
- Second Batch: 3m 30s
- Convection: No
We initially set the toast knob to Medium—right at the Toast icon—for our Toast test. The bread came away very dark on the bottom but barely toasted on top. Then, the halfway point to Medium gave the toast no color.
Eventually, we settled on a point 3/4 the way to Medium—around 3 minutes 30 seconds on the timer—as the best option, and awarded it a score of 7.3/10.
At our optimal toasting setting, the Hamilton Beach produced 4 pieces with a great, slightly golden-brown color. Though the oven doesn’t have a convection fan, the color distribution was about 80% even so we gave the toast an 8/10.
The first batch of toast was crispy on the outside while still soft and moist on the inside, so we gave it an 8/10 for taste. Our head chef, Tuyet Pham, said it would go very well with everything including sandwiches, soup, omelets, and eggs benedict.
The second batch represented a significant decrease in performance, scoring only 5.5/10 for consecutive usability. The toast had an uneven, dark brown color plus a burnt flavor. If you want the second batch to be the same as the first, remember to only turn the knob halfway to Medium—around 1 minute 55 seconds on the timer.
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: 9m 10s
- Convection: No
This oven left a bit to be desired when we tried baking a 9-inch thick-crust meat pizza. We gave it a score of 6.6/10.
It took 9 minutes and 10 seconds to bake a pizza which was slightly faster than the recommended 10 minutes on the label. It only garnered a score of 5.8/10 after being compared to other toaster ovens in our Pizza test, though.
The crust had a good golden brown color but was soft, so we could only give it a 7/10. The toppings were caramelized unevenly and some areas of cheese got darkened. On the bright side, the toppings weren’t dry, so they got a 7/10. After tasting, our chef gave it a 6.5/10.
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: No
Even though the Hamilton Beach could comfortably fit a 3 lb chicken for our Whole Roasted Chicken test, its performance was far from perfect, scoring only 6.3/10.
The oven took 1 hour—our standard for this test—to cook the chicken to a desirable color, so we gave it an 8/10.
After roasting, the skin took on an even golden color on top but only a very light caramelization on the bottom — although that was also even. Unfortunately, the skin was very soft, so we could only give it a 5.5/10.
The chicken reached an internal temperature of 165-176°F which was very close to the USDA recommendation. However, there were pink spots near the bone so we could only give it a 6/10.
The meat was acceptable in terms of texture and juiciness, but didn’t stand out as remarkable. Our chef gave the chicken a 6/10 for taste.
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: 27m 15s
- Convection: No
Baking 12 oz of french fries clearly wasn’t the Hamilton Beach oven’s forte, and it came away with a score of 5.1/10.
This oven took 27 minutes and 15 seconds to put some color into the french fries. That exceeded our time limit of 25 minutes, though, so it failed the cooking time criterion of our Baked French Fries test.
Even though the fries had some golden ends, most of them basically had no color. We gave them a 6.5/10.
Despite being spread out on the baking pan, the fries didn’t crisp up, so they got a 6/10. Our chef gave the fries a 6.5/10 for taste.

- Height:12.6" (32.0 cm)
- Material:Stainless steel
- Color:Silver
- Door Handle:Cool-touch
- Tray Indicators:No
- Crumb Tray:Removable
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:9.3 lbs (4.2 kg)
- Length:18.5" (47.0 cm)
- Width:14.6" (37.0 cm)
- Height:9.4" (24.0 cm)
- Material:Stainless steel

The Hamilton Beach has a stainless steel exterior. Our measurements of the oven’s footprint were 18.5" x 15.56" x 9.41"—marginally different from the manufacturer’s provided 18.74" x 15.24" x 9.41".
What stands out most is the roll-top door with a cool-touch handle. It moves up and out of the way, giving you safe and easy access to your food before, during, and after cooking.
The oven has a back buffer to prevent it from being pushed too close to the wall. Unlike many other toaster ovens, though, you can’t wrap the power cord around the buffer.

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
- Broil
The bake and broil functions will be all you need if you know your way around the kitchen. The temperature knob also includes a Min setting which, at 100°F, can act as a ‘keep warm’ option.
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:No
- Lighting:No
- Tray Levels:2
- Rotisserie:No
- Safety Hook:No
Unfortunately, the 31127D doesn’t have any interior features worth mentioning, not even internal lighting or a convection system like the Cuisinart TOA-60. The only thing it has is four nichrome heating elements.
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:13.0" (33.0 cm)
- Width:12.2" (31.0 cm)
- Height:7.7" (19.5 cm)
The Hamilton Beach has enough capacity for 6 slices of toast, a 3 lb chicken, or a 12-inch pizza.
We measured the cooking chamber’s volume to be around 19.92 liters which was vastly different from the manufacturer’s stated capacity of 10 liters. However, this could be because we measured from the cooking chamber’s walls to walls whereas the manufacturer stopped before reaching the heating elements.
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:35.0" (88.9 cm)
- Type:2-prong plug
- Power:1400 W
- Rated Output:120 V ~ 60 Hz
The power cord protrudes from the bottom of the oven which can create some inconvenient bends. Nonetheless, roughly 35" is plenty of cord length for household use. However, the oven doesn’t have a storage place for the cord.
Accessories
- Length:14.2" (36.0 cm)
- Width:13.4" (34.0 cm)
- Height:0.3" (0.7 cm)

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:11.3" (28.8 cm)
- Width:9.4" (23.8 cm)
- Height:0.7" (1.8 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The baking pan is correctly sized to keep messy food from dripping directly onto the heating elements. It slides into the brackets on the baking rack’s underside, so it’s a perfect fit. Unfortunately, though it has a coating, it isn’t completely non-stick so it can accumulate some stains after a tough roasting mission.

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.

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.
The Hamilton Beach is well-constructed out of durable stainless steel. Its contoured knobs turn smoothly and are a nice simple touch.

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.
The Hamilton Beach only has three simple control knobs but there are a few things to pay attention to. If you wish to set the timer knob for less than 10 minutes, you must first turn it beyond the 10-minute mark (to start the heating) and then roll it back to the setting you want.
Precisely adjusting time and temperature can be a bit difficult but it’s not a major problem. If you’re concerned, use an external timer and an oven thermometer for more accurate measurements.
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 simple analog control panel makes it very easy to adjust settings on the fly. Once the timer counts down to the Off position, you’ll hear a chime and the oven will shut itself off. Since there’s no digital display, the oven won’t draw any more power even if you leave it plugged in.
The oven’s exterior only gets hot to the touch after a long cooking time at a high temperature. The door can be kept partially open at many degrees but keep in mind that it doesn’t switch the oven off.
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.
We cleaned the Hamilton Beach in accordance with our toaster oven cleaning guide. The oven was easy to clean thanks to its surface coatings and the fact that it has no tricky nooks and crannies.
The removable crumb tray made it easy to clean up the crumbs, though we still had to tilt the oven to get the last of them. Unfortunately, after our Whole Roasted Chicken test, the baking pan accumulated some discoloration that we weren’t able to remove even with a paste of baking soda and water.
