Highlights

Integrated Pro Cook System Achieve the perfect level of doneness from rare to well-done at the touch of a button using the integrated thermometer and Auto Temp Detect Intelligence, eliminating the need for guesswork.
Smart Surround Convection Features a high-velocity fan and rear heat source that provides up to 10x the convection power of a traditional built-in oven, delivering an all-around crisp without the need to flip or rotate food.
10-in-1 Versatile Functionality A multi-purpose kitchen powerhouse with 10 specialized cooking programs: Air Fry, Whole Roast, Air Roast, Bake, Dehydrate, Pizza, Broil, Toast, Bagel, and Reheat.
XL Family-Sized Capacity The extra-large interior accommodates two 9×9 baking trays, a 12 lb. turkey, or up to 9 slices of toast simultaneously, making it ideal for large family meals and entertaining.
Rapid Preheat and Cooking Saves time in the kitchen with a lightning-fast 90-second oven preheat and cooking speeds up to 30% faster than a standard full-size convection oven.

Pros & Cons

Pros

  • Exceptional Versatility and Performance: The 10-in-1 functionality allows users to air fry, bake, roast, and dehydrate with consistent results, often making traditional ovens obsolete. It features a large interior capacity that can accommodate whole chickens, 13-inch pizzas, or multiple trays of food simultaneously.
  • Rapid Preheat and Cooking Speed: The unit features an incredibly fast preheat time of approximately 90 seconds, which is significantly faster than standard full-sized ovens. This efficiency allows users to start cooking almost immediately and reduces overall meal preparation time.
  • Integrated Smart Thermometer: The Pro Cook System includes a built-in thermometer probe that monitors internal food temperature and automatically shuts off the unit when the target doneness is reached. This feature eliminates guesswork and ensures meats are cooked perfectly and remain juicy.

Cons

  • High Noise and Vibration Levels: A frequent complaint is the excessive noise generated by the convection fan, which some users compare to a jet engine or an airplane. Additionally, several reviewers reported distracting metallic rattling or vibrations during operation.
  • Large Countertop Footprint: The unit is quite bulky and deep, requiring substantial counter space and clearance from walls due to its rear-venting design. Its size may be problematic for smaller kitchens or standard-depth countertops.
  • Challenging to Clean: Maintaining the interior is difficult because grease and food splatters can easily reach the exposed heating elements and the back fan. Users noted that baked-on residue is hard to remove and the crumb tray can be tricky to empty without spilling.

    This has turned out to be an excellent purchase. We have had it for a few weeks and cooked and air-fried a variety of things. So far it has worked well and we are optimistic that would continue. Our last toaster oven was an even pricier Breville–which worked great for two years and then just went haywire. That is the same experience many Breville owners appartently have had according to reviews. The Ninja has gotten good scores for extended reliability.

  6. Used just about every day.

    This has been a great addition to our kitchen. It is used practical every day. We had the small ninja that you can flip (great design) but it was too short for a lot of things. Although this one takes up a lot more room, it has been used a lot more. The only thing I noticed that I don’t like is that is does not bake evenly and I have to turn the pan during cooking (noticed this while cooking rolls). I would still buy this again so that my big oven is not used as much to save on electric. I have not yet used some of the features but the ones I have – they seem to work well. Heats up quick like my other one. The air fry seems to take much longer to cook than the smaller one I had.

  7. Noisy and now wont work!

    The first one right out of the box was very loud. We returned it. The second one was somewhat quieter, and we could live with the noise. After several months, it is now dead. After turning on and beginning to run, it stops, and you get the message to call.

  8. We’re pleased with this purchase

    Very easy to use, the presetting is very good and easy to work with. It is a little heavy to move around but if you have a set place for it is perfect size. If you are planning on doing family size pizza it won’t fit in . Really good for baking bread, cookies, cakes. In general I recommend it .

  10. The best oven

    This was the best purchase I have made. I live full time in a rv and my oven is small and I can only cook one thing at a time, I now can cook two things at the same time . Well worth the money for this item.
