Breville BOV450XL Mini Smart vs Cosori Air Fryer Toaster Oven Side-by-Side Comparison
Our Verdict
- Performance (50%)6.8/10
- Design (25%)6.4/10
- Usability (25%)6.2/10
- Performance (50%)8.0/10
- Design (25%)9.4/10
- Usability (25%)8.3/10
Both the Breville BOV450XL Mini Smart Toaster Oven and the Cosori Air Fryer Toaster Oven (CO130-AO) are our best-to-buy picks. You can already tell who’s the winner when the latter is our definitive best-to-buy pick while the former is only in the small category.
Comparing the two shows the size difference can bring different degrees of investment in design, usability, and most importantly, resulting performance. The Cosori has pretty much all the features the Breville can offer but better.
Although the Breville has the highest performance scores among small units, it just can’t compare with the Cosori’s consistent top-tier results. A larger cooking chamber allowed the Cosori to have more heating elements, an interior light, and a convection system.
The Cosori also has a higher power draw and more accessories to tackle all of our cooking tasks, including toasting bread, baking pizza, roasting whole chicken (using its rotisserie kit), and air-frying fries (using its air-fryer basket).
Both toaster oven has toggle switches for convection settings, lighting, and temperature conversion. However, the Cosori simply has a more intricate control panel with a more informative digital display and more intuitive buttons. The Breville does have a non-stick interior that’s rare for any size though.

Toast
- Function: Toast
- Number Of Slices: 4
- Toast Level: 4/7
- Cooking Time: 3m
- Second Batch: 2m 36s
- Convection: No
After following our Toast test procedures, we determined that this oven’s toasting level 4—3 minutes on the timer—was the best option, giving it a score of 7.9/10. At level 3, the bread was very lightly toasted and at 5 was darker than ideal and had a more uneven surface color.
At toast level 4, the Breville produced 4 pieces with mottled light golden to golden-brown color which looked quite appetizing. The color was not evenly distributed due to the oven’s lack of a convection system, though, so we gave it an 8/10.
The first batch of toast was nicely crispy outside while still soft and moist inside, deserving an 8/10 score for flavor. Our head chef, Tuyet Pham, determined they would go well with pretty much anything including an omelet, eggs benedict, and particularly sandwiches.
Even though the oven automatically adjusted the timer to 2 minutes 36 seconds, the color of the second batch was a bit darker. Also, the second batch was crispier than the first which made it more suitable for soup.
Overall, it’s a 7.5/10 for consecutive usability. Remember to reduce the heat by one level if you want the same result. Thanks to its high wattage, this oven has the fastest cooking time for toast among the toaster ovens we’ve tested thus far.
- 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.
Pizza
- Function: Bake
- Temperature: 450°F
- Cooking Time: 10m 30s
- Convection: No
The Breville oven did not agree with the 9-inch thick-crust meat pizza we tried to bake. We gave it a score of only 5.5/10.
This oven took 10m 30s to bake the pizza which was only slightly longer than the recommended 10 minutes on the label. However, 10 minutes was the time limit of our Pizza test, so it failed the cooking time section.
The crust had a nice golden color but was soft and dry—a possible consequence of the long cooking time. Therefore, we could only give it a 7/10.
The toppings were mostly dry with uneven color. Plus, the cheese wasn’t well melted, so it received a 6.5/10.
After tasting, our chef gave the pizza a 7/10.
- 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.
Whole Roasted Chicken
- Function: Bake
- Temperature: 350°F
- Cooking Time: 1h 5m
- Convection: No
The Breville could barely fit the 3 lb chicken for our Whole Roasted Chicken test and scored a 6.9/10. The chicken grazed the safety guards that protect the upper heating elements while we were putting it in. During the roasting, quite a bit of grease splashed inside the oven and caused the heating elements to smoke a little.
The oven took 1h 5m to cook the chicken which was just 5 minutes longer than what we consider standard, so it got a 7.5/10.
After roasting, the skin had a quite even coloring although a bit too light, and remained soft. We awarded it a 7/10. In addition, the skin on the back got stuck to the baking pan during roasting.
The chicken’s internal temperature was 168-171°F which was very close to the USDA recommendation. However, there were a few pink spots near the bone, so we gave it a 7/10.
Even though the meat was juicy, the unappetizing chicken skin was enough that our chef lowered the score to 6.5/10 for taste.
- 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.
Baked French Fries
- Function: Bake
- Temperature: 400°F.
- Cooking Time: 25 m
- Convection: No
The Breville did an acceptable job of baking 12 oz of french fries, scoring a 6.5/10.
It took 25 minutes, the limit of our Baked French Fries test, so this oven got a 5/10.
Except for a few golden pieces, the fries mostly lacked color. They only deserved a score of 7/10.
The fries had a variety of textures, none of which were good. The golden fries were dry and yet only slightly crispy. Also, the ones that lacked color were really soft, so it was only a 6.5/10.
Our chef gave the fries a 7/10 for taste.
- 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.

Exterior
- Weight:10.0 lbs (4.5 kg)
- Length:15.7" (40.0 cm)
- Width:14.2" (36.0 cm)
- Height:8.9" (22.5 cm)
- Material:Stainless steel
- Color:Silver
- Door Handle:cool-touch
- Tray Indicators:Yes
- Crumb Tray:Slide-out
The small size didn’t stop Breville from designing a sturdy stainless steel outer shell. The shape of the back buffers makes it easy to wrap the power cord around them once things have cooled.
Also, the tray-level indicators on the glass door and the slide-out crumb tray are always nice touches. However, the oven’s exterior doesn’t provide good grip points to carry the oven.
We measured the oven’s footprint to be 15.74" x 14.17" x 8.86" which was slightly different in terms of height from the manufacturer’s 16.1" x 14.2" x 10.4".
- Weight:15.7 lbs (7.1 kg)
- Length:20.0" (50.7 cm)
- Width:17.3" (44.0 cm)
- 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.

The control panel consists of 1 control knob for 8 functions and 4 buttons to set the time, temperature, and/or toasting mode. The digital display and the Start/Cancel button both shine blue when the oven’s plugged in and red when it’s cooking.
Beyond the standard stuff, you’ll find 3 unique buttons: Temperature Conversion (°F-°C), Frozen Foods, and A Bit More. The latter adds a specific amount of time depending on the cooking function.
The LCD screen will display ‘E01’ or ‘E02’ when there is a non-resettable issue with the appliance. When this happens, immediately unplug the cord from the wall outlet and call the Breville Customer Service Center.
The ‘E03’ shows up when the oven temperature exceeds its design limit. Should this occur, unplug your oven, allow it to cool for 15 minutes, then plug it back in.
The ‘E04’ appears when the room temperature is below the set minimum. If this happens, unplug the oven and move it to a warmer area.

The LED screen will display ‘E1’ when there’s an open circuit in the temperature monitor and ‘E2’ for a short circuit.
Cooking Functions of the Breville BOV450XL Smart Toaster Oven
- Toast (7 levels, 4 slices maximum)
- Bagel (7 levels, 4 slices maximum)
- Bake (1h 30m maximum)
- Broil (High and Low levels, 20 minutes maximum)
- Pizza (55 minutes maximum)
- Roast (1h 30m maximum)
- Cookies (55 minutes maximum)
- Reheat (370°F maximum)
For safety reasons, all cooking functions have a predetermined timer limit after which the oven stops cooking. If you want to continue cooking, simply operate the oven in standard mode. The High setting of the Broil function does the job faster than Low and you’ll need to experiment with it to learn how quickly it cooks.
- 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.
Interior
- Heating Elements:4 quartz
- Convection Fan:No
- Lighting:No
- Tray Levels:3
- Rotisserie:No
- Safety Hook:No
The Breville’s interior has a non-stick coating, 4 heating elements, and 3 tray levels (quite rare for its size). However, it has no internal lighting or convection system.
The oven uses 4 quartz heating elements, each with its own safety guard to prevent direct contact with baking pans and food. Unlike the more common nichrome style, these don’t heat the air in the oven, but rather radiate the infrared heat directly to the food or pan.
Overall, they produce more heat and cool down faster than nichrome. In addition, they’re easier to clean and are more energy-efficient but not as durable. However, if grease splashes onto the heating elements while cooking, it’ll leave permanent stains.
- 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.
Capacity of the Breville Smart Toaster Oven
- Length:11.5" (29.2 cm)
- Width:11.0" (27.9 cm)
- Height:6.7" (17.0 cm)
The BOV450XL had enough space for four slices of toast, an 11-inch pizza, or barely a 3 lb whole chicken.
We measured the cooking chamber’s volume to be 13.86 liters compared to the manufacturer’s provided capacity of 12.74 liters. However, it could just be because we measured from the cooking chamber’s walls to walls whereas the manufacturer stopped before reaching the heating elements.
- 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.
Power Cord
- Length:40.9" (104.0 cm)
- Type:3-prong plug
- Power:1800 W
- Rated Output:110 V - 120 V ~ 60 Hz
The power cord is roughly 40.94"—plenty of length for household use—and can be wrapped around the back buffers for storage. The plug also has a nice little handle which makes it easier to grab.
- 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.
Accessories
- Length:11.5" (29.2 cm)
- Width:10.3" (26.3 cm)
- Height:0.3" (0.7 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The rack fits perfectly on the guide rails, which helps prevent accidents when placing your food in the oven.
- 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.
Accessories
- Length:10.6" (27.0 cm)
- Width:10.6" (27.0 cm)
- Height:1.2" (3.0 cm)
- Material:Stainless steel with enamel coating
- Dishwasher Safe:Not advisable
Although the baking pan is a bit smaller than the rack, it still has more than enough space for a 3 lb chicken. Thus, it keeps most of the mess off the heating elements.
However, even with the enamel coating, the chicken skin still stuck to the pan during our roasting test. Also worth noting is that the dishwasher can damage this coating.
- 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.
Build Quality
The Breville is well-constructed and durable with a high power rating of 1800 W. All of its parts fit nicely and work smoothly, especially the LCD display and the buttons.
Thanks to the good insulation of the casing, the oven gets hot to the touch only after cooking for a long period of time at high heat.
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.
Breville Mini Toaster Oven Usability Review

- Ease of Use (50%)4.0/10
- Cleanability (20%)9.0/10
- User Control (30%)9.5/10
- Ease of Use (50%)8.0/10

User Control
The Temperature Conversion button is a nice touch for international users. The cooking time can be adjusted in increments of 1 minute and the temperature in increments of 5°F. For some reason, this differs from what the user manual states.
The manual says that the FROZEN FOODS button adds the right amount of additional time needed to defrost the target foods in the Toast, Bagel, Pizza, Cookies, and Bake functions. However, we didn’t find it very useful since cooking time depends heavily on the food quantity and personal preference.
The A BIT MORE button, where each press adds a pre-set amount of time to each function, has a similar problem. It only seemed useful when the oven was still cold and we wanted to skip the preheating phase.
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.
Ease of Use
The Breville has an automatic preheating phase that lasts 1m 45s. Our tests saw it reaching around 180°F in that time. The temperature alert will sound when the oven reaches your selected temperature. Then, it will sound three times at the end of the cooking cycle.
It’s very easy to adjust cooking settings during use, especially compared to an analog unit like the Mueller MT-175. However, even though this oven doesn’t turn off upon opening the door, the door won’t stay partially open – it’s all or nothing.
According to the manufacturer, the Element iQ System’s smart algorithms focus power where and when it’s most needed, creating ideal cooking conditions every time. However, we didn’t notice a significant difference in performance when comparing it to other ovens of the same size/wattage.
If it’s not actively cooking, the oven will go into STANDBY mode after 10 minutes with no interaction. Although unplugging the oven resets your customized setting, Breville recommends doing so anyway after you finish using it.
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).
Cleanability
We cleaned the Breville in accordance with our toaster oven cleaning guide. Thanks to the stainless steel exterior and non-stick interior, it was very easy to clean. Removing crumbs was also easy thanks to the slide-out crumb tray, although we still had to tilt the oven to get the last of them out.
The upper heating elements got stained by smoke from splattered grease during our roasted chicken test. Fortunately, we had no problem removing the stains by brushing the elements with a paste of baking soda and water. We were also able to easily scrub the burnt chicken skin off of the baking pan.
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.
