    8.0/10

Looking at the overall score, the Black+Decker Convection Toaster Oven (CTO6335S) definitely loses to the Breville Smart Oven Pro (BOV845BSS).They both are large digital convection toaster ovens, the first one is plain while the second is fancy.

The Breville has much higher scores in terms of design and usability and also costs around three times as much as the Black+Decker. On the other hand, if you simply want a toaster oven that can cook just as well and don’t want to spend as much, then the Black+Decker is for you.

Both toaster ovens have a slide-out crumb tray, but the Breville has a thicker casing for better heat insulation. They also have internal lighting but the Breville takes a step further with its non-stick interior coating for easy cleaning.

The current settings for the cooking mode, timer, and temperature are more clearly shown on the Breville's control panel. The oven’s buttons register more easily, not to mention the extra toggle switches for temperature conversion, convection settings, and frozen foods.

Here’s the catch, they tied in their cooking performance. Both machines have equally good performance scores. Yet, given the Breville's greater power output, we anticipated more from it. We believed that its quartz heating elements might be subjected to inconsistency.

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.

We began our Toast test by choosing toast level 4—the middle one out of the 7 options—for 4 pieces which we placed on tray level 2. The four pieces of bread came out only slightly toasted on top. We then chose level 5 and the surface color was more appetizing but less even.

So, we tried again one last time at level 6 but it produced four completely brown pieces of toast which were also a bit dry. In the end, we settled for level 5—5 minutes 13 seconds on the timer—as the best possible option with a score of 6.8/10.

At this level, the toast had a perfect golden brown color around the center of the oven. However, it was lighter the further it got to the rear, so we could only give it a 7/10 for even surface color.

The unevenness also translated to the texture where the toast achieved great crispiness in the golden brown areas but got softer in the lighter areas. This resulted in a 6.5/10 for taste from our chef.

Our head chef, Tuyet Pham, determined they would be good to have with omelets and sandwiches. They could be served with soups or eggs benedict but wouldn't make a perfect pairing.

We placed the second batch of four in immediately after the first one. We chose level 5 again whereupon the oven automatically deducted the timer to 3 minutes 42 seconds.

Because the oven was already hot, the second batch showed an increase in evenness for both surface color and crispiness deserving a 7/10. This batch would be more suitable for soups.

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.

For our Pizza test, we didn’t use the pizza presets because they didn’t include the correct size for our choice of pizza. This was also a good chance to test out the Breville pizza pan, but we were surprised to find the overall score ended up at 6.8/10.

Thanks to the oven’s strong power output and convection setting, it only took 4 minutes to bake a 9-inch thick-crust meat pizza placed on tray level 2. This was extremely fast and deserved a 10/10 according to our data on average toaster oven performance.

However, the pizza still had a problem with cooking evenness. A quarter of the entire crust was golden brown but the rest of it lacked color. As you can imagine, the golden brown part was crispy on the outside and soft on the inside while the lighter part was simply soft throughout. Thus, we could only give the crust a 6/10.

The same issue applied to the toppings which had a nice caramelization where the crust was golden but not much in the substandard area. The cheese was also not quite melty so the toppings also got a 6/10.

Altogether, our chef gave the pizza another 6/10 after tasting it. We chose not to increase the cooking time of the pizza as it could result in burning the part of the crust and toppings that were already properly baked.

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.

For our Whole Roasted Chicken test, we placed a 3 lb chicken in a belly-up position onto the broiling rack and baking pan combo on tray level 1. The outcome was pretty satisfactory, scoring a 7.5/10.

The Breville took 1 hour to roast the chicken to a desirable color which was our standard for an 8/10. The skin overall had a golden color, especially at the wings and the tips. However, it still had some very light areas.

In addition, when we flipped the chicken after the first 40 minutes, some of the skin on the back of the chicken got stuck to the broiling rack. This was an indication that the skin was soft and didn’t crisp up much despite having the convection fan deployed. Thus, we gave the skin a 7/10.

The oven was able to maintain a good internal temperature so the chicken was cooked all the way through leaving behind no pink spots. However, the cooking time was a little long, so the chicken’s internal temperature ended up at 198°F which was higher than the recommended 180°F by the USDA. We gave the doneness of this chicken an 8.6/10.

Nonetheless, the meat wasn’t dry and combined with the skin it was enough to get a 7/10 for taste from our chef.

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.

Despite the power draw of 1800 W, the Breville didn’t perform as well in baking french fries as many toaster ovens with the same output earning a 6.1/10. Looking at the results from the Ninja DT201, our assumption was that the broiling rack wasn’t as efficient for this purpose as an air fryer basket.

For our Baked French Fries test, we didn’t turn on the Frozen Foods toggle because we needed to keep track of the exact cooking time. The oven took 24 minutes to bake 12 oz of frozen fries on tray level 2 which wasn’t very fast. Compared to many other toaster ovens we’ve tested, it could only get a 6/10 for cooking time.

Even though we gave the fries a toss after the first 10 minutes, they still came out with uneven coloring scoring a 6.5/10. Most of the thinner fries had a pretty good golden color while most of the thicker ones had a much lighter color.

To the same degree, the fries had different textures throughout earning it a 6/10 for this testing component. The pieces with a golden color were crispy outside and soft inside while the lighter ones were mostly just soft all the way through.

With all of that in mind, our chef couldn’t give a score higher than 6/10 after tasting the fries.

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".

An exterior feature that stood out to us on the Breville is its side-positioned carrying handles which double up as air ventilation holes for the convection system. We were also impressed by the indicators on the glass door that direct you to its three tray levels and many cooking functions.

The Breville has an interesting automatic eject feature for when the oven rack is in the middle guide rail. This is achieved thanks to a magnet in the corresponding position on the oven door.

Further attention to the design shows in the convenient slide-out crumb tray and strong base stands. The oven’s door handle is cool-touch and provides a good grip. Unfortunately, the back buffers are not long enough to create ample space between the back of the oven and the wall.

Our measurements of 18.39" x 15.94" x 10.78" for the oven pretty much coincided with the dimensions provided by the manufacturer—18.5" x 14.5" x 11". The 1.5-inch difference in width is probably because we took the door handle into account.

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.

The BOV845BSS has a non-stick interior coating which explains the black color. The black interior isn’t a problem though thanks to the oven’s interior light. When necessary, you can remove the glass cover to change the interior light bulb which is a G9 type, 25 W, 120 V.

Each of the three tray levels has a safety hook to prevent the oven rack from accidently sliding all the way out. However, only the bottom one is positioned further in, specifically for this purpose. The convection system, while quite powerful, is pleasantly quiet.

The Breville has five quartz heating elements that use infrared light to cook. Compared to the more common nichrome heating elements, these heat up and cool down faster while also being easier to clean and more energy-efficient but don’t last as long in terms of durability.

For this unit, each heating element has a safety guard to prevent direct contact with baking pans and trays. However, if grease splashes onto the heating elements while cooking, it’ll leave permanent stains.

The Breville’s cooking chamber has a capacity of 25 liters which is quite common among large toaster ovens. This was one of the rare occasions where the cooking chamber’s volume that we measured matched the manufacturer’s stated capacity.

Many large units can also fit 6 slices of toast but not all can fit a 13-inch pizza like the Breville. This oven can also fit a 9-cup muffin tray or a 4.16-liter Dutch oven.

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.

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.

The Breville has a sturdy build and is made from durable stainless steel. The oven has good heat insulation and a good convection system so the casing rarely gets hot to the touch—only after a long cooking time at a high temperature (>400°F).

Its LCD has a good color contrast, the control dials turn smoothly, and the buttons have good responsiveness. On another note, this unit doesn’t provide enough oven racks to make full use of the three tray levels and additional accessories.

Note: This product adheres to the California Proposition 65.

User Control

9.5

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.

The timer of the Breville is specified by the minute. The temperature can be adjusted in 5°F/5°C increments by turning the knob slowly and in 10°F/10°C increments by turning the knob fast.

You can freely adjust the time and temperature while the oven is running but will need to press Cancel to change the cooking function. Keep in mind that this may repeat the automatic preheat phase if the temperature is lower than the manufacturer’s set point.

Regarding the extra unique features, the Temperature Conversion button is a nice touch for international users. The convection setting can be applied to almost all cooking functions except for Toast, Bagel, and Broil.

The Frozen Foods button adds a predetermined amount of time but only to the Toast, Bagel, Pizza, and Cookies functions. However, we didn’t find it very helpful since cooking time depends heavily on the food quantity and personal preference.

As for the extra cooking functions, the Pizza presets, with predetermined timers, aren’t very useful as they allow for temperature adjustment but don’t take the current temperature into account. The same goes for the Slow Cook function which has a predetermined temperature that isn’t stated in the manual.

According to our observation, the oven reaches and maintains at 325°F on both Low and High so we didn’t get the point of having two settings. In addition, these temperatures are quite high compared to more common slow cookers’ which are around 200°F on low and 300°F on high.

If you want to adjust the temperature for slow cooking in this oven, you can choose the Bake function for which the timer also reaches ten hours.

Ease of Use

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.

The Breville has an automatic preheat phase for functions that allow for temperature adjustment as mentioned above. According to the manufacturer, this feature will preheat the oven to 75% of the input temperature before sounding an alert. However, our observation showed that it would always preheat to around 300°F taking about 4m 55s regardless of the input temperature.

Due to the eject feature mentioned above, keep in mind to open the door slowly to prevent the rack from sliding too far outward. The door can be kept partially open at an 80° angle to let food cool inside the oven. Doing this doesn’t stop the oven, unlike some others. Be careful as the door can slam shut if you slip while closing.

When the automatic preheat phase or the cooking cycle ends, the interior light will turn on and then turn off after 30 seconds, similar to when you press the light switch. Unfortunately, there’s no way to keep the light on indefinitely.

If not used for 10 minutes, the oven goes into standby mode until you press Start again. Nonetheless, it’s still advised to unplug the oven after use. Your customized setting will remain in the memory of the oven until changed or the oven is unplugged from the power outlet.

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.

Cleaning the Breville was extremely easy thanks to its stainless steel exterior and non-stick interior. There were some tricky nooks and crannies in the cooking chamber but luckily, there was minimal grease splashing after all of our tests.

The enamel baking pan and broiling rack sported some stubborn stains from the roasted chicken even after we washed them with dish soap. Nonetheless, we took care of them quite easily by brushing them with a paste of baking soda and water. 

The slide-out crumb tray was also helpful for cleaning up the crumbs but we still had to tilt the oven to get all of the crumbs out.
