Instant Omni Plus 18L vs Ninja Foodi XL Pro Toaster Oven Side-by-Side Comparison
Our Verdict
- Performance (50%)8.1/10
- Design (25%)9.7/10
- Usability (25%)8.4/10
- Performance (50%)8.0/10
- Design (25%)8.8/10
- Usability (25%)9.5/10
After both going back and forth, the confrontation between the medium-sized Instant Omni Plus 18L and the large Ninja Foodie XL Pro came to a tie. Nonetheless, it was a satisfactory conclusion with both toaster ovens having their own moments to shine.
The two machines were equal in terms of interior and build quality by having more than four heating elements, interior lighting, a convection system, and a sturdy build. What gave the Instant a higher score in exterior and the edge it needs in the design department were its slide-out crumb tray and carrying handles.
Both units have similar scores in user control with their informative digital display and numerous features. However, the Ninja is significantly easier to use thanks to its wider timer and temperature range as well as its highly visible display.
The larger cooking chamber also means it’s easier to clean, not to mention the lack of nooks and crannies. As a result, the Ninja scored a returning goal in the usability department.
The most important aspect is still the performance—if the oven better cooked the food. The Ninja won it toast thanks to it having an extra rear nichrome heating element that toasted the bread more evenly. This feature also benefited the Ninja’s roasted chicken test, gaining another edge.
The Instant also has an extra top nichrome heating element but it wasn’t deployed for toasting. Nonetheless, the unit equaled the playing field with its excellent air-frying capabilities shown in the fries test.
Both units have the same power output and a convection system, so it was hard to determine the reasons why one unit was better at cooking certain food than the other. Overall, we deemed the Instant better for air frying and the Ninja for larger servings of food.

Toast
- Function: Toast
- Number Of Slices: 4
- Toast Level: 2/5
- Cooking Time: 5m 25s
- Second Batch: 4m 1s
- Convection: No
Using the steps of our Toast test, we determined that level 2—5 minutes 25 seconds on the timer—was the best option scoring a 7.3/10. In comparison, the level 1 and 3 had a more uneven while being lighter and darker surface color respectively.
The Toast Level 2 of the Instant Omni Plus 18L produced four pieces with an 85% even golden brown color. Since the fan couldn’t be deployed, the toast had some darker spots and lighter areas resulting in a 6/10.
The first batch of toast was nicely crispy while still soft and moist inside and we gave it an 8/10 for taste. Our head chef Tuyet Pham determined it would be excellent with omelet and eggs benedict but not so good for sandwiches or soup.
This is one of the few ovens with a smart program that automatically deducts time to reach certain temperatures when the oven’s already hot. Thus, the surface color of the toasts was quite consistent throughout multiple batches. In addition, due to its extra crispiness, the second batch was determined to be good enough for soup.
If you want the second batch to be similar to the first, remember to lower it by one level. Overall, the score for consecutive usability was 7/10.
- Function: Toast
- Number Of Slices: 4
- Toast Level: 5/7
- Cooking Time: 5m 15s
- Second Batch: 4m
- Convection: No
We began our Toast test by setting the toast function to level 4. With four slices of bread placed on tray level 3, they came out very light on top. The bottom side had a bit more color but it wasn’t enough.
After that, we cranked the oven up to level 6. That gave us a very even color, but it was too brown. In the end, we settled for toasting at level 5, which ran for around 5 minutes 15 seconds, as the best option, earning a score of 8.3/10.
Under this setting, the toast mostly received a light golden brown color. However, there were various areas that were a bit darker or lighter, possibly due to the bread’s varying thickness. The unevenness in surface color, especially on the bottom, prevented us from scoring it higher than 8.5/10.
Interestingly, this unevenness in the bread gave it a variety of textures throughout which deserved another 8.5/10. Our head chef, Tuyet Pham, determined the toast would go great with pretty much everything including omelets, sandwiches, eggs benedict, and soup.
The light golden brown areas were slightly crispy on the outside and moist on the inside. On top of that, the golden brown areas were crispy all the way through and the light golden areas gave us a different, softer texture.
For the immediate second batch at the same toast level, the oven automatically reduced the time to 4 minutes. This time, the toast had a more even brown color than the first batch. However, there was a more apparent unevenness on the bottom with colors that ranged from white to dark brown.
Nonetheless, nothing was burnt, so it did not taste bitter. The extra crispiness made the toast even better for soup. All in all, the oven got a 7.8/10 for consecutive usability.
Pizza
- Function: Bake
- Temperature: 450°F
- Cooking Time: 3m 50s
- Convection: High
The Instant Omni Plus, having a very strong convection system, did not seem ideal for baking a 9-inch thick-crust meat pizza resulting in an 8.6/10.
A cooking time of only 3m 50s was extremely fast compared to the recommended 10 minutes on the label. After comparing it to other toaster ovens in our Pizza test, it was more than enough for a 10/10.
The crust, although golden brown, was a little soft with some lighter and darker areas due to the short cooking time plus strong fan. It got an 8/10.
The entire surface was a little too dry due to all the convection. In addition, while the cheese was nicely melted, caramelization wasn’t even due to the short cooking time. Thus, the final score for the toppings was 8.2/10.
Our chef gave the pizza an 8.5/10 for taste.
- Function: Pizza
- Temperature: 450°F
- Cooking Time: 5m
- Convection: Low
Our Pizza test was one of the few occasions where we felt the Ninja didn’t measure up to its potential. We suspect the score would be better if we were baking a fresh pizza instead of a store-bought 9-inch thick-crust meat pizza. Anyhow, we settled on a score of 6.5/10 for this test.
After preheating, we placed the baking tray and the pizza at tray level 3 as suggested by the digital display. The oven only took 5 minutes to bake the pizza compared to the recommended 10 minutes on the label. According to our standards, this deserved a 10/10 for cooking time.
Unfortunately, despite having the convection system on low, the crust was only golden on the side closest to the fan. The other half of the crust lacked color. In addition, such a short amount of time wasn’t enough to crisp any of the crust (even the golden side). Thus, we could only give the crust a 6/10.
The reason we had to stop the cooking so early was that the meat and the bell peppers on the golden half of the crust were beginning to char. Luckily, the toppings on the other half cooked properly. However, it seemed the cheese didn’t have enough time to melt, so the toppings only got a 5/10.
Considering the state of the crust and the toppings, our chef gave the pizza a 6/10 after tasting it.
Whole Roasted Chicken
- Function: Roast
- Temperature: 350°F
- Cooking Time: 50 minutes
- Convection: Yes
Following our Whole Roasted Chicken test, we chose a 3 lb chicken and it fit without a problem scoring an 8.4/10.
However, cleaning up was a big hassle as there wasn’t enough space below to use the drip pan. Worse still, during cooking fat splashed everywhere inside the oven causing the heating elements to smoke.
The roasting time was 50 minutes which was shorter than average and worthy of a 9/10.
The rotisserie kit and high convection together produced perfectly golden brown crispy skin deserving a 9.8/10. One thing to note is that due to the meat being considerably moist, the skin lost its crispiness in a relatively short time span.
The smooth rotation and high convection also allowed the whole chicken to be thoroughly cooked without any pink spots in just 50 minutes. The internal temperature was only a little higher than the USDA recommended 165°F-180°F at 178-190°F, so it got a 9/10.
The meat was almost fall-off-the-bone. Unfortunately, with it being so moist—to the point of softening the skin, our chef could only give it a 7 for taste.
- Function: Air Roast
- Temperature: 350°F
- Cooking Time: 40m
- Convection: Maximum
The strengths of the Ninja really shined through in our Whole Roasted Chicken test, scoring an impressive 9/10. We placed our 3-pound whole chicken in the air fryer basket with plenty of room to spare and slid it onto tray level 3. We also placed a baking pan below to catch any drippings.
With this test, we were able to confirm the manufacturer’s claim that food in this oven didn’t need to be turned, especially when using its air fryer basket. Nonetheless, to stay consistent with our test parameters, we still flipped the chicken after the first 25 minutes.
The oven took only 40 minutes to cook the chicken all the way through and to create an appetizing-looking and crispy skin. It was one of the fastest cooking times among our toaster ovens and deserved a whopping 10/10, on par with the Cosori CO130-AO which uses a rotisserie kit.
The skin was evenly golden from the bottom to the top. It also crisped up nicely around the tips of the wings and drumsticks as well as areas with a lot of fat.
However, it would seem the surface of the chicken cooked so quickly that a lot of the fat didn’t get rendered out from the skin. Thus, while the outer layer of the skin was crispy, the inside was soft. The skin’s softness from the remaining fat, unfortunately, prevented it from scoring higher than 8.5/10.
Checking with a meat thermometer, we found the chicken’s internal temperature to be 194°F-199°F which was quite high compared to the USDA recommended of 165°F-180°F. This was the reason we didn’t continue cooking longer for better skin caramelization. Our chef was afraid that would overcook the chicken. After carving the chicken, we found no pink spots in the meat and gave it an 8.4/10 for doneness.
With such a short cooking time, the meat remained delightfully juicy. Also taking into account the texture of the skin, our chef gave the chicken a 9/10 for taste.
Baked French Fries
- Function: Air Fry
- Temperature: 400°F.
- Cooking Time: 15m
- Convection: High
The Instant Omni Plus was excellent at baking 12 oz of french fries with a score of 9.3/10.
After performing our Baked French Fries test on different toaster ovens, we came to the conclusion that the ideal cooking time for baked french fries was 15 minutes. However, it wasn’t the fastest one on our list so it scored a 9/10.
The strong convection combined with the air fryer basket produced evenly golden fries worthy of a 9.8/10 for color.
What helped the color also baked perfectly crispy fries while retaining a nice amount of moisture. This earned the oven another 9.8/10 for the texture of baked french fries.
Our chef gave the fries a 9/10 for taste.
- Function: Air Fry
- Temperature: 400°F
- Cooking Time: 19m
- Convection: Maximum
We put 12 oz of frozen fries into the air fryer basket and slid it onto tray level 3. We also gave the fries a toss after the first 13 minutes. The overall score for our Baked French Fries test was 7.8/10.
The oven took 19 minutes to bake the fries which was enough for a 7.7/10. With this oven, our chef had to balance the cooking time with the color of the fries. If we stopped baking too early, the thicker fries would lack color; if too late, the thinner fries might be burnt.
The fries’ colors ranged from light golden on the thicker ones to golden brown on the thinner ones. This unevenness resulted in a 7.5/10.
The colors of the fries largely reflected their texture. The longest and thickest fries had a slightly crispy outside and a very moist interior. Meanwhile, the shortest and thinnest fries were completely crispy all the way through.
The silver lining was that average-sized fries got perfect, crispy surfaces with moist interiors. While the texture varied, none of them were bad, so we gave the overall batch an 8/10.
Considering the varied colors and textures of the fries, our chef awarded them a respectable 8/10 after her taste test.

The Ninja toaster oven arrived firmly positioned between two foam pads inside an eye-catching package. Its seven included accessories were also fitted nicely in carton boxes. The oven came with a separate user manual, a tips and tricks sheet, and a recipe booklet.
Exterior
- Weight:25.4 oz (721 g)
- Length:16.5" (42.0 cm)
- Width:15.8" (40.0 cm)

- Tray Indicators:Yes
- Crumb Tray:Yes
An example of the Instant Omni Plus 18L’s clever design is the slide-out crumb tray not to mention its two strong base stands as well as air ventilation on two sides and the back. For safety, it has two buffers on the back to prevent the oven from sitting too close to the wall and a cool-touch door handle.
To accommodate its many cooking functions, there are tray-level indicators on the glass door. Our measurements of the oven’s footprint of 16.54" x 15.75" x 13.90" were quite different from the manufacturer’s 12" x 12" x 13.89" in terms of length and width.
We could explain that the difference in width was because we also took the dial and the back buffers into account but not the difference in length. Nonetheless, we didn’t find this to be a problem.
- Weight:26.4 lbs (12.0 kg)
- Length:16.9" (43.0 cm)
- Width:20.3" (51.5 cm)
- Height:13.4" (34.0 cm)
- Material:Stainless steel
- Color:Silver
- Door Handle:Cool-touch
- Tray Indicators:No
- Crumb Tray:Removable
The Ninja has many ventilation holes on its casing, especially at the back and on the bottom, to accommodate its extremely powerful convection system. A unique design choice that stood out to us was the fact that the control panel was located on the oven’s cool-touch door handle.
Most ovens situate their control panel on the casing, thus adding to the oven’s footprint. By combining the control panel with the door handle, the oven can also maximize space for its cooking chamber.
You don’t need to worry about the handle slamming to the ground or countertop since the door hinge does a great job of keeping the door firmly in place. While it doesn’t have tray-level indicators on its glass door, the digital display does show the recommended tray level for every function.
Our measurements of the oven’s footprints were 16.93" x 20.28" x 13.34" which jived closely with the manufacturer’s 17.09" x 20.22" x 13.34". For these measurements, we also took into account the door handle and rear buffer.
The oven has a buffer on its backside to prevent it from being pushed too close to the wall. The feature could be a bit longer, in our opinion. We do need to mention that the bulky shape of the oven and its lack of carrying handles may make it difficult to move around.

Besides the automatic oven preheat feature, it features an audio cue to turn food halfway through the input cooking time.
Audio cues include the beeps when you plug in the oven, select a function as well as adjust time and temperature, and when the oven finishes cooking. According to some reviews we’ve seen, they can be a bit loud, especially for households with children and/or pets. However, they can be turned off by pressing and holding the control knobs for 5 seconds until the screen displays S OFF.

When plugged in, the On/Off switch will light up. You then press it to turn on the oven and its digital display. The door handle is black while the digital display is white, creating good color contrasts.
The control panel includes two buttons to adjust cooking functions, two for time, two for temperature, a light toggle, a Start/Stop button, and the ‘2-level’ button.
The ‘2-level’ button is unique to this Ninja. It suggests the best rack levels for cooking two trays of food at the same time. This even allows you to roast a tray of meat and a tray of vegetables at the same time. Everything is explained in detail in the Ninja recipe booklet.
Cooking Functions
- Air fry (180°F - 450°F)
- Broil (350°F - 450°F)
- Bake (180°F - 450°F)
- Roast (180°F - 450°F)
- Dehydrate (85°F - 175°F)
- Reheat (120°F - 360°F)
- Warm (170°F - 300°F)
- Toast (level 1-5)
Even though there’s no Rotisserie function, the oven comes with a tailored rotisserie kit and a Rotation Toggle. Besides making dried fruits, herbs, and meat jerky, the Dehydrate function is also ideal for proofing bread dough at 85°F and Low Convect.
- Air Fry (250°F–450°F)
- Whole Roast (250°F–450°F)
- Air Roast (250°F–450°F)
- Bake (180°F–450°F)
- Dehydrate (85°F–200°F)
- Pizza (180°F–450°F)
- Bagel (level 1-7, 1-9 slices)
- Toast (level 1-7, 1-9 slices)
- Broil (HI or LO)
- Reheat (100°F–450°F)
Each cooking function on the Ninja has its own temperature range to match the function’s purpose. What’s special about this model is that each function deploys a specific convection level and a specific number of heating elements, each tailored to the dishes stated in the recipe booklet.
Whole Roast, for example, uses a high fan speed and the rear convection heat source to provide rotisserie-style results. Air Roast uses the maximum fan speed and the rear convection heat source to quickly cook food for a crispy outside and juicy inside.
Air Fry also uses the maximum fan speed and the rear convection heat source to cook food as quickly as possible for the crispiest results. Pizza uses the rear convection heat source but a low fan speed to avoid drying the pizza crust and toppings too much.
Bake operates the same way as Pizza. The same goes for Dehydrate, which has a lower temperature range for removing moisture from foods.
The remaining cooking functions don’t deploy the convection fan. Broil activates the top heating elements on the high setting to provide top-down heat for a crispy finish. On the other hand, Reheat activates the top and bottom heating elements on the high setting.
Toast also activates the top and bottom heating elements but on the medium setting to quickly and evenly brown both sides of your bread. Bagel, however, activates the top heating elements on the medium setting and the bottom heating elements on the high setting. This is because the recipe book instructs you to place the bagel slices cut-side up.
Interior
- Heating Elements:4 quartz and 1 nichrome
- Convection Fan:Yes
- Lighting:Yes
- Tray Levels:4
- Rotisserie:Yes
- Safety Hook:No
The Instant Omni Plus has four golden quartz heating elements. These pipes use infrared light to cook, which produces more heat and also cools down faster.
They are also easier to clean and more energy-efficient 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.
Featuring safety guards, the heating elements are kept out of direct contact with baking pans and trays. The oven even includes a coil nichrome heating element at the top, specifically for broiling.
To top it off, this oven has a powerful and not noisy convection system as an interior light. In addition to 4 tray levels, you can make use of the baking rack with its rack-up and down positions.
- Heating Elements:5 quartz + 1 nichrome
- Convection Fan:Yes
- Lighting:Yes
- Tray Levels:4
- Rotisserie:No
- Safety Hook:No
The best aspects of the DT201 are its convection system and heating elements. Together, these two systems are designed to eliminate the need for rotating your pans or flipping foods halfway through cooking, a fact that we confirmed with our performance tests.
The convection fan provides airflow of up to 130 CFM (cubic feet per minute). Such a powerful convection system would usually be very noisy but thanks to the door’s tight seal, it wasn’t a problem.
The Ninja has three quartz heating elements on top and two on the bottom; most other similarly-sized units have four in total. What really separates this oven from the rest, however, is its third heat source in the rear, right where the convection fan sits. This nichrome heating element surrounds the convection fan cavity to properly and consistently heat the airflow.
The quartz heating elements heat food directly using infrared light, so airflow isn’t always important. Meanwhile, nichrome heating elements heat up the air around them, so their effectiveness can be improved with the help of convection systems.
The cooking chamber has four tray levels with engraved numbers 1-4 from the bottom up. It also has a coating but it’s not 100% non-stick, so it may be prone to stubborn stains.
Of course, an oven like this won’t lack an interior light. While this oven isn’t designed to accommodate a rotisserie kit, its performance showed that it could provide the same results.
Capacity of the Instant Pot Omni Plus 18L
- Length:13.8" (35.0 cm)
- Width:12.6" (32.0 cm)
- Height:8.7" (22.0 cm)
The Instant Omni Plus can comfortably fit a 12-inch pizza or a 4-pound chicken which is true to its description. However, it can’t quite fit 6 slices of toast. Moreover, when roasting only a 3-pound whole chicken with the rotisserie kit, there wasn’t enough space to fit a baking pan below. This wasn’t the case with a larger unit like the Cosori CO130-AO.
We measured the cooking chamber’s volume to be roughly 24.6 liters—a lot different from the manufacturer’s provided capacity of 18 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.
- Length:14.5" (36.8 cm)
- Width:11.8" (30.0 cm)
- Height:11.0" (27.9 cm)
The Ninja has the largest cooking chamber out of all the toaster ovens we’ve reviewed so far, measuring around 30.82 liters. While the manufacturer didn’t state a specific capacity, this unit could comfortably accommodate a 12-pound turkey.
Each rack level can also fit nine slices of toast or a 12-inch pizza. With the 2-level even cooking feature, you can roast a 5 lb whole chicken and a tray of vegetables at the same time.
Power Cord
- Length:2.8 ft (0.9 m)
- Type:3-prong plug
- Power:1800 W
- Rated Output:120 V ~ 60 Hz
The power cord is roughly 33.46"—more than long enough for household use. However, the cord can’t fully wrap around the two back stands as they are too high up.
- Length:3.2 ft (1.0 m)
- Type:3-prong plug
- Power:1800 W
- Rated Output:120 V ~ 60 Hz
The power cord is roughly 38 inches — plenty for household use. Unfortunately, the oven doesn’t have a storage place for the cord. The rear buffer is also not designed to wrap the cord around.

The removable crumb tray is a useful accessory for cleaning up pesky crumbs. The tray also fits perfectly with the oven’s shape so as to minimize crumbs falling onto the oven’s floor when you take it out.
Build Quality
The Instant Omni Plus 18L is a well-built and intricate piece of equipment, to say the least. It provides a helpful cooking status bar, smart programs, and automatic features. The oven does consume a lot of electricity so make sure your outlet can provide and handle 1800 W.
The meticulous design shows in the bottom tray, safeguards for heating elements, and cooling fan for its mainboard. However, the bottom tray can easily slide out if you tilt the oven. Also, during our roasting of a whole chicken, the hot drippings created some oxidation on the crumb tray.
The Ninja’s casing is made of durable and thick stainless steel which gives the oven good heat insulation. Thus, during our tests, the oven’s exterior only got hot to the touch after cooking for a long time at a high temperature (>400°F).
The digital display has a good color contrast which makes it easy to see—an advantage compared to the Instant Omni Plus 18L. Its buttons are highly responsive and very sturdy. All of the accessories are designed well to fit their purposes and make the most out of the oven’s capacity.
Unfortunately, possibly due to uneven metal expansion, the pans that we received bent when heated. Even though they flattened out again once they cooled, this was still a manufacturing flaw.
Moreover, the light button seemed to be broken when we received the oven. We could sometimes turn the light on and sometimes not. Nonetheless, we deemed these flaws to be specific to our particular unit, so we didn’t deduct too many points in terms of build quality.

The Instant Omni Plus 18L has 8 settings to choose from but can serve more than 10 functions. Although the LCD display could be improved with better contrast, it’s not a big problem.
The master-control knob can be confusing for first-timers but it should take little effort to get familiarized with it. The temperature can be adjusted in 1°F increments by turning the knob slowly and in 10°F increments by turning the knob fast. Also, the timer is specified by the minute.
If you want to readjust the setting during cooking, simply tap the feature and adjust it with the knob. Don’t tap Cancel as it will reset your inputs and repeat the automatic preheating.
The convection setting is applicable to almost all except for toast. One thing to note from the manual is that most recipes recommend reducing the temperature by 25°F when convection is on.
The convection fan speeds can toggle between high and low which is not very common for ovens, especially at the same price range. The two exceptions are Air Fry which always uses High Convect and Warm using Low Convect.
The control panel of the Ninja is far from simple but the digital display presents all the information in a way that’s pleasing to the eye and not at all complicated. In addition, its buttons are really straightforward.
The timer adjusts in 1-minute increments when under 1 hour and 5-minute increments when over 1 hour. You can also hold the +/- buttons for 2 seconds to activate faster scrolling in 5-minute increments.
The temperature can be increased in 5-degree increments. You can also hold the +/- buttons for 2 seconds to activate faster scrolling in 10-degree increments.
For the Toast and Bagel functions, the preset temperature is 450°F, similar to all toaster ovens. Adjusting the Temp/Shade and Time/Slice buttons simply changes to a predetermined cooking time.
The best part, however, is that you can select the number of bread slices and toast up to 9 slices at once. You can also manually adjust the time once cooking has started to better choose your preferred shade of browning. This toasting performance really puts the Ninja in a class of its own.
The Air Roast and Air Fry functions are basically distinguished by their tray positioning, especially when cooking two trays at the same time. To utilize the Air Roast function, for instance, you can place the meat dish on tray level 1 and the vegetable dish on level 3. As for the Air Fry function, you can cook two trays of the same food to the same results by placing them on tray levels 2 and 4.
The Dehydrate function is another stand-out feature in our minds. The recipe booklet outlines instructions for several types of food. You can purchase additional dehydration accessories to dehydrate up to 4 levels at one time. The Reheat function can also be used to keep your food warm at around 120°F.
Ease of Use
When you adjust temperature and time for a function, the Instant Omni Plus saves your setting for next time use. After the oven finishes cooking, it will beep and automatically switch to Keep Warm mode until the display shows End.
After a period of no interaction, the digital display will show the word OFF similar to when you’ve just plugged it in. You’ll then need to push the knob once to turn it on. It’s advised to unplug the oven after you finish using it.
The light automatically turns off after 30 seconds of no interaction and turns on 30 seconds before finishing cooking. Opening the oven door pauses the cooking but the light stays on for another 30 seconds. Closing the oven door resumes the cooking but it will go into stand-by mode resetting all inputs after 5m30s.
Taking the rotisserie kit out of the oven can be a bit tricky even with the lifter. However, with a bit of practice, it’ll be no problem at all. The oven has good heat insulation, so the casing doesn’t get too hot to the touch at 350°F and 400°F but be careful at 450°F.
The oven has a short automatic preheat phase which lasts 1 minute 25 seconds and heats the oven to around 200°F. While this feature wasn’t very useful in practice, the oven still reaches the correct temperature extremely quickly. All cooking functions use this phase except for Toast, Bagel, Broil, Dehydrate, and Reheat.
Whenever you select a function, the oven will display the optimal oven rack position. As you cycle through functions, you’ll notice the tray-level recommendations change for the best results. When the door is open, display settings freeze to prevent any accidental changes to the cooking cycle.
The 2-level even cooking feature allows you to cook two sheet pan meals at once which can be very helpful for big gatherings or weekly meal prep. The door hinge allows for partial opening at any angle greater than 75° which most toaster ovens can’t do.
The manufacturer’s claim of ‘30% faster cooking than a traditional full-size convection oven’ was a bit arbitrary. The same goes for ‘up to 30% crispier results vs. a traditional convection oven’. Nonetheless, our performance tests did show crispier and juicier results than many other toaster ovens.
We also couldn’t confirm the claim of ‘up to 50% more even baking results vs. a leading countertop oven’. Our observations of the cooking process did show, however, that the oven distributed heat so evenly that there was no need to flip food midway through the bake.
Keep in mind that opening the door stops the oven but not the interior light. During the cooking process, the light will turn off automatically after one minute, and there’s no way to keep it on.
The oven turns off automatically after 10 minutes of no interaction. Nevertheless, we still suggest you unplug the oven after use for safety reasons.
Cleanability
We cleaned the Instant Omni Plus 18L following our toaster oven cleaning guide. Despite having an internal and external coating, it still wasn’t easy to clean due to some very tricky nooks and crannies. The small gaps between the heating elements and internal walls didn’t help either.
Most of the mess came from the considerable fat splatter from roasting a whole chicken. It left difficult stains on the heating elements and their safeguards which were already tricky to clean.
With the removable oven-bottom tray, cleaning up the crumbs was extremely easy but we still had to tilt the oven to get all of the crumbs out. On the bright side, having thought it would be difficult to clean caramelized bits of food from the air fryer basket due to the fishnet design, we were happy to find this wasn’t the case.
The exterior’s stainless steel finish made it very easy to clean. In addition, the interior has plenty of space, so the grease rarely reached the cooking chamber’s walls.
However, the interior doesn’t have a non-stick coating so we had to put in a little effort to clean the grease. We were also worried that grease could have splashed inside the fan cavity.
The baking pans and broiling rack are easy to clean thanks to their enamel coating. The small downside to this was that the stains that did appear stuck out like a sore thumb.
We could remove most bits that fell off our food thanks to the removable crumb tray. Plus, when the door was fully opened, its hinge left a small space where we could just sweep the remaining crumbs out.
