Breville BOV450XL vs Black+Decker CTO6335S 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%)7.0/10
- Design (25%)6.6/10
- Usability (25%)6.1/10
The Breville BOV450XL and the Black+Decker CTO6335 stand toe to toe in our performance tests, but the latter has a slight edge. While the Breville is better at making toast and baking french fries, the Black+Decker scores more consistently throughout. It also has the upper hand in baking pizzas and roasting a whole chicken.
Although both ovens have four efficient quartz heating elements, the Breville uses 1800 W, which usually results in better performance compared to the Black+Decker’s 1500 W. However, this strength is hindered by the absence of a convection system and by the inconsistent heating of the elements which is due to the oven’s smart algorithms.
While both have more cooking functions apart from just baking and broiling, the Breville has a slight advantage because of its unique features, including a temperature conversion button. In addition, although both ovens have a control panel that’s easy to use, the Breville’s buttons and dial are more reliable and responsive than the Black+Decker’s.
Both ovens have a slide-out crumb tray and a standard baking rack and pan, but the Black+Decker is equipped with a broiling rack. Though both have a black interior and no internal lighting, the Breville has an edge, thanks to its non-stick coating.
Overall, the Breville BOV450XL is a well-constructed, small-sized, smart countertop toaster oven. On the other hand, the Black+Decker CTO6335 is a good budget, large-sized countertop convection toaster oven with a sturdy tamper-resistant casing.

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: 4/7
- Cooking Time: 5m 10s
- Second Batch: 3m
- Convection: No
With our Toast test, we were able to determine that level 4—5 minutes 10 seconds on the timer—was the best option scoring a 7/10. Levels 3 and 5 respectively had a lighter and darker than ideal, although even, surface color.
The toast level 4 of the Black+Decker scored a 7/10 for color. The four pieces had areas of different colors ranging from golden brown to just slightly golden. This was probably due to uneven heating of the elements and the convection fan not running.
Despite the color, the first batch was crispy on the outside and soft on the inside so we gave it a 7.5/10 for taste. Our head chef Tuyet Pham determined that it would go great with eggs benedict and omelet.
Even with the automatic toast time adjustment feature, the quality of the second batch was reduced in every aspect. The color was lighter and the texture was less crispy so we had to give it a 6/10 for consecutive usability. If you want the second batch to be the same as the first, lower the toast level by one.
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: 7m 30s
- Convection: Yes
The Black+Decker did an ok job of baking a 9-inch thick-crust meat pizza earning it a 6.8/10.
Compared to the recommended 10 minutes on the label, it took 7m 30s to bake the pizza, which was fairly solid. However, after comparing it to other toaster ovens in our Pizza test, we could only give it a 7.5/10.
The crust had a good golden brown color but was soft and a little dry — possibly due to the longer cooking time. Thus, it could only get a 7/10.
The toppings were mostly dry with an uneven coloring, plus the cheese wasn’t melty so it got a 6.5/10.
In the end, our chef gave the pizza a 6.5/10 for taste.
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: Bake
- Temperature: 350°F
- Cooking Time: 1h
- Convection: Yes
Following our Whole Roasted Chicken test guidelines, we placed a 3 lb chicken on a broiling rack on a baking pan of the Black+Decker with plenty of space to spare. The abundance of space gave it some advantages over smaller units like the Breville BOV450XL despite a lower power output. Overall, the Black+Decker received a 7.7/10 for this test.
It took the oven 1 hour, the standard amount of time, to roast the chicken to a desirable color so we gave it an 8/10. The skin came out a light golden color but it was uneven despite being flipped after the first 40 minutes. In addition, it was soft, so it got a 6.5/10.
The chicken was thoroughly cooked but the internal temperature was a tad bit high at 189°F-192°F compared to the USDA recommended 165°F-180°F so we gave it an 8.8/10. The meat was very juicy but the lack of roasted aroma and crispy skin resulted in a 7.5/10 for taste from our chef.
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: 25m 50s
- Convection: Yes
With a score of 5.6/10, the Black+Decker left a lot to be desired in the Baked French Fries test. In comparison, the same-sized Cosori CO130-AO did a much better job with its higher power output and air fry basket.
This oven took 25m 50s to bake 12 oz of fries which was just a bit too long over the limit of our Baked French Fries test. Thus, it failed our cooking time section. Coloring was uneven among the fries ranging from nicely golden to almost none so they could only get a 7/10.
The textures were also uneven and, worse, none was particularly good. The golden fries were only a little crispy and the ones that lacked color were soft. Overall, it was a 6.8/10 for this test.
Our chef gave the resulting fries a 7/10 for taste.

- 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:12.9 lbs (5.8 kg)

- Height:10.6" (27.0 cm)
- Material:Stainless steel
- Color:Silver
- Door Handle:cool-touch
- Tray Indicators:No
- Crumb Tray:Slide-out
Despite its large size, the Black+Decker only has air ventilation holes around the side where the convection fan is. The two buffers on the back to keep the oven from being too close to the walls are quite sturdy. Also, a slide-out crumb tray is always a nice touch.
Our measurements of the oven’s footprint were 19.29" x 13.38" x 10.62" which were a lot different in terms of length and height compared to the manufacturer’s 22.8" x 13.4" x 15.5".

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.

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.
- Cookies
- Pizza
- Frozen snacks
- Potato
- Bake
- Broil
- Toast
- Bagel
The eight cooking functions are useful for beginners and experienced cooks can freely adjust the time and temperature of each to their liking.
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 quartz
- Convection Fan:Yes
- Lighting:No
- Tray Levels:2
- Rotisserie:No
- Safety Hook:No
The Black+Decker only has two tray levels but you can make use of the flippable rack to effectively create two more levels. The oven has a convection system but no internal lighting—unlike the Ninja DT201—which can be an inconvenience considering the interior is black.
The oven has quartz heating elements that use infrared light to cook. They have their own safety guards to prevent direct contact with baking pans and trays.
Compared to the more common nichrome heating elements, they produce more heat and cool down faster. They are also more energy-efficient and easier to clean but don’t last as long in terms of durability. However, if grease splashes onto the heating elements while cooking, it’ll leave permanent 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:12.6" (32.0 cm)
- Height:7.9" (20.0 cm)
The CTO6335S can comfortably fit 6 slices of toast, a 12-inch pizza, and a 3 lb whole chicken. While the manufacturer didn’t state the oven’s capacity, we measured the cooking chamber’s volume to be around 23 liters.
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:24.8" (63.0 cm)
- Type:3-prong plug
- Power:1500 W
- Rated Output:120 V ~ 60 Hz
Even though the length of 24.8" is enough for household use, the power cord protrudes from the bottom of the oven reducing the usable length. In addition, it’s not long enough to wrap around the two back buffers.
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:10.0" (25.4 cm)
- Height:0.9" (2.2 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The baking rack can be placed in the oven either way up, effectively adding two more tray levels for the oven.
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:13.3" (33.8 cm)
- Width:10.2" (25.8 cm)
- Height:1.2" (3.0 cm)
- Material:Stainless steel
- Dishwasher Safe:Yes
The baking pan is large and, being 100% compatible with the broiling rack, it catches all the drippings. This prevents any hot mess from dirtying the heating elements thus mitigating that potential fire hazard. However, it’s not 100% non-stick so you may have some stubborn stains to deal with after a heavy roasting session.
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 Black+Decker CTO6335S is equipped with a tamper-resistant screw to prevent removal of the outer cover. However, the bottom tray can easily slide out and the door can also open if you tilt the oven.
Throughout our tests, we noticed that the oven’s large capacity is somewhat counteracted by its power output of 1500 W. We speculated on its ability to perform more efficiently if it were 1800 W.

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 Black+Decker has 8 functions but the convection toggle is only applicable to Bake. There’s an indicator light for when a function starts and stops — which are two separate buttons on the control panel.
For all functions except Toast and Bagel, you can push the increment and decrement buttons once to change the temperature in increments of 5°F and hold to change in increments of 25°F. After pressing the Timer button, the same goes for cooking time but in increments of 1 minute and 10 minutes. For Toast and Bagel, simply choose a level from 1 to 7.
Unfortunately, even though the label shows a stay-on function, we couldn’t find it in the control panel or the user manual. A small thing we didn’t like about the buttons was that they sometimes didn’t respond well.
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.
For all functions except for Toast and Bagel, the Black+Decker has an automatic preheat feature. This will always heat the heating elements to 350°F, which takes around 4m 20s, before starting the actual timer. Then, the internal temperature will gradually stabilize around your input temperature.
One thing to note is that you cannot change the temperature or time during the automatic preheat cycle. You can only do so once the oven reaches the selected temperature.
Keep in mind that the oven’s exterior gets hot to the touch quite quickly. In addition, it doesn’t turn off upon opening the door, unlike some others. The door also can’t be opened partially.
This oven beeps with each push of a button and does so three times when it finishes cooking. The oven always remembers the last selected setting until it’s unplugged. It’s advised to unplug the oven after you finish using it as the digital display doesn’t turn off after a period of no interaction.
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.
We cleaned the Black+Decker following our toaster oven cleaning guide. With the oven having an internal and external coating, cleaning was quite straightforward.
However, even with the slide-out crumb tray, we still had to tilt the oven to get all of the crumbs out. In addition, some of them got stuck inside the heating element safeguards and we had no way of getting them out.
