Description

Meet the Ninja Double Oven, the countertop oven that unlocks the power of two ovens in the counter space of one. Only Ninja has the FlexDoor that creates 2 separate ovens so you can cook 2 meals, 2 ways at different temperatures and cooking times. Use just the Top Rapid Oven for quick snacks, sides, and sheet pan meals—or the Bottom Convection & Air Fry Oven for larger roasts, bakes, or air frying up to 6 lbs of wings. You can also sync both independent ovens to cook a full course meal that finishes cooking at the same time with Smart Finish technology. While your meal cooks, FlavorSeal technology prevents flavor crossover between ovens. The Smart Cook System precisely monitors temperatures with the leave-in thermometer, so you don't have to. Two oven cavities in one eliminate back-to-back cooking for 65% faster meal-making than your traditional oven so you can put your wall oven out of business. Plus, this countertop dual oven features 12 cooking functions for the ultimate versatility.

    • Good Value - Absolutely Love
Style: Stainless 12-in-1
Review Image by S.S. S.S.
I absolutely love this ninja oven. It makes it so easy to prepare meals, especially dinner. I can pop veggies in the top and cook chicken on the bottom. Once the timer is set there’s nothing else to do except relax until your meal is ready. It’s easy to cook whole meals, but I can also toast bagels, and perform much similar kitchen functions too. It’s replaced many appliances in my kitchen. Would absolutely recommend to anyone. The only thing I would suggest for future improvement is to automatically turn on the “keep warm” function once the timer is up. Especially if the other timer for the other section is still running. All in all would recommend and purchase again. ... show more

    • Best yet Countertop Oven and Air Fryer
Style: Stainless 12-in-1 with Thermometer
We've had other countertop oven/air fryers and used them daily. This Ninja double oven is by far the best. Having two ovens in one is remarkably efficient and makes meal production faster and easier. You can do steak in one, fries in the other, or a meal for adults in one, and different items for the kids in the other, or an entree in one and a dessert in the other. This appliance is well built, well thought out, and the learning curve on the controls is short.... but it's there, especially regarding use of the thermometer. The internal food temperature thermometer is a big plus when you correctly use it. We are thrilled with this double oven and have fun using it every day. Only downsides are it's a bit noisy (a minor issue), a bit larger than traditional toaster ovens, and the large sheet pans and air fryer basket are supposed to be washed by hand, so cleanup is a bit of a chore. All in all, however, we would buy this again in a minute! ... show more

    • Versatile and Convenient Double Oven
Style: 12-in-1 with Thermometer
This Ninja oven is impressive in both design and performance. The double oven feature with FlexDoor makes it easy to cook two different dishes at once without mixing flavors. The smart thermometer takes the guesswork out of cooking, and the 12 functions give plenty of flexibility for baking, roasting, air frying, and more. Heats up quickly, cooks evenly, and is simple to clean. A great upgrade for any kitchen that saves both time and space. ... show more

    • Very nice oven -just a couple of issues.
Style: 12-in-1 with Thermometer
The size is very good. Having 2 ovens in-one is a plus. Air-fry works great. Have been using it for several months now and found that toasting takes longer than it did in the first few weeks. Very noticeable difference. Two negatives: 1. There is a cooling fan that runs after the oven stops (for ALL functions). It runs insanely long and does not seem to serve any purpose. Nor is it detecting the temp. Tested this by unplugging and plugging back in. The fan did not kick back on, so it must be on a fixed timer. All products have a "mean time before failure (MTBF)". My theory is the cooling fan will wear out far sooner than it should and might render the oven useless. So I've put the oven on a short power strip to cut power and stop the fan from running. No toaster oven (or toaster) I've ever had over many decades has every had a post-op cooling fan. 2. The lower oven does not have a broiler element. You can only broil in the top oven. Not terrible, but did not expect that. It does otherwise operate very well. The outside skin stays remarkable cool when cooking. There is a "slight" bleed-thru of heat from the lower to the upper oven, but doubt it's enough to have any real effect on top-baking time/temp. ... show more

    • An amazing oven that adds a lot of versatility.
Style: Stainless 12-in-1
Having used a smaller Ninja digital air fryer pro for almost 5 years, i wanted to update to allow larger baking spaces while staying on side of my kitchen counter. This oven fits the bill. Dual options for larger roasts and smaller oven for straight baking, toasting, and broiling. There is definitely a learning curve to dial in temps and time, but so far every meal has come out terrific and quicker than a giant oven. Clean up is a breeze as well as long as you wipe it down after each use. Lots of modes seems confusing, as really some seem to just duplicate efforts. But that still allows for a lot of versatile baking styles to produce quality meals with fewer steps. Very glad I upgraded to this terrific appliance. ... show more

I contacted Amazon regarding the damaged oven. They delivered me a new one the next day and picked up the damaged one a couple days later. Very much appreciated!! Great customer service Amazon, I give you 5 stars for that! As for the oven, we are loving it! We bought it mainly for the air frying and it works very well. We use it almost everyday to air fry, chicken breasts, pork chops, turkey burgers, hamburgers, salmon, shrimp, etc. Cooks the food well and evenly. I do not know why some of the reviews say it is loud. I do not think it is at all. Its easy to use, just read the instructions and learn how. I would for sure recommend. Delivered damaged. Huge dent on the side! This is going to be really hard to return because of the size/weight and torn box!!! ... show more

This Ninja double stack countertop oven & air fryer is a total kitchen game-changer! I can bake, air fry, roast, and broil at the same time thanks to the dual-zone cooking. The FlexDoor design makes it easy to check food without losing heat, and everything comes out crispy, juicy, and perfectly cooked. Cleanup is a breeze, it looks gorgeous on my counter, and it’s replaced my toaster oven, air fryer, and half my other appliances. If you want a space-saving, all-in-one cooking powerhouse, this is it! ... show more
