Compared to Other Toaster Ovens

6.8 Performance

The Breville BOV450XL produced great toast and adequate results when roasting a whole chicken and baking french fries. However, it left a lot to be desired when we tried a pizza. We suspect this was due to the inconsistent heating of the oven.

Moreover, the fact that the oven didn’t have a convection system didn’t help in this regard. A model of the same brand that improved on this was the medium-sized Breville BOV845BSSUSC.

7.8 Toast

Scoring Components ↓

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.

5.5 Pizza

Scoring Components ↓

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.

6.6 Whole Roasted Chicken

Scoring Components ↓

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.

6.5 Baked French Fries

Scoring Components ↓

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.

6.4 Design

The Breville BOV450XL has a good capacity for a small oven. However, while it has a high wattage and quartz heating elements, it lacks a convection system, so the fancy heating elements don’t improve performance much.

Not being designed to accommodate a convection system was probably why it didn’t come with any useful additional accessories like an air fryer basket. And as a kicker, the interior has a non-stick coating but is black and contains no internal lights, unlike the Panasonic NB-G110P-K.

In the Box

• Model: BOV450XL
• Warranty: 1-year limited
• User Manual
• Baking Rack
• Baking Pan

On the packaging were some illustrations and basic information, and the oven was couched nicely between two foam pads. Breville’s user manual explains in detail how each oven function works. 

The default accessories, a baking rack and baking pan, were packaged in a fitted carton box. You can opt to buy a separate 11” pizza pan and/or a broiling rack to cover more cooking methods.

6.0 Exterior

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".

Control Panel

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

• 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.

4.0 Interior

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.

Capacity

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.

Power Cord

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.

Accessories: Baking Rack

The rack fits perfectly on the guide rails, which helps prevent accidents when placing your food in the oven.

Accessories: Baking Pan

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.

8.0 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.

6.2 Usability

The Breville BOV450XL is simple to use and to clean. Unfortunately, most of its unique features aren’t useful, including the toggles and cooking presets. Its smart heating algorithms as well as automatic preheat phase also didn’t add much to the test dishes we cooked. Cleaning it was an extremely easy task, though.

8.0 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.

4.0 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.

9.0 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.
