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.

  1. I love this oven!

    While a little on the pricey side for a “toaster oven,” this little thing acts like a giant and has made cooking a lot easier. It can air fry, roast, toast, and bake. I haven’t tried making a cake, but my biscuits have come out great! Not to mention, my pork roast, roasted vegetables, and air-fried chicken! The smart cook feature with the thermometer makes cooking a roast a simple process. Probe your roast, turn it on, set the internal temp, and forget it! I would definitely buy another one!

  2. Great Kitchen Addition

    This thing is a beast. We use it almost daily. Why heat up the whole kitchen with a big oven. This one will do more than our oven. Great for preparing smaller meals. IE for a family of 4 or less. Toaster ovens have come a long way.

  3. Another great Ninja product

    I’ve been using the Ninja Air Fryer Countertop Oven + Pro Cook for a while now, and I’m honestly very satisfied with it. It’s become one of my most-used appliances in the kitchen. The air fryer function works great, but what really stands out is the versatility — I can make so many different recipes in this one unit, from roasted veggies and crispy chicken to baked goods and reheated leftovers.
    It heats up quickly, cooks evenly, and delivers that nice crispiness without needing much oil. The Pro Cook features are a bonus — multiple cooking functions, easy-to-use controls, and accessories that help you get the most out of every meal.
    Cleaning is relatively easy if you do it right after use, and the size is perfect for a countertop without taking over too much space. Highly recommend it if you’re looking for a multifunctional appliance that actually performs well.

  4. Anybody have this issue

    Whenever I am using the Smart Cook System using the Preset mode and the thermometer that came with the Ninja unit, the cooking automatically stop BEFORE the temperature (current temp) of the meat has reached the Target temperature dictated by the Doneness button. For example, I selected Beef and Doneness level of medium. When the cooking start, the Ninja display Target 140 deg F and Current temp of 75 deg F. After the Ninja Current temp reached 130-134 deg F, the ninja shutdown. Now, if I change the Doness to Medium Well. The Target temp is 145 deg F when I start cooking. But Ninja stop at around 140 deg F. The Ninja never reach the target temp before stop cooking. Anybody have this issue? Unit seem defective or what?

    I’ve used the Ninja foodi for years and found that I was having to make batches which took a long time. I decided to upgrade and have been pleasantly surprised. Now I cook full meals at once. Loving it so far!

    I’ve been using this thing for a few months now, and I haven’t run into any issues with it at all. It’s HUGE and can hold a lot of food at once, making it great for parties, gatherings, and big families. It cooks food in record time and can crisp up the skin on chicken amazingly well. It’s HEAVY and feels very well built, which is a nice change from the flimsy crap so many places sell these days. I’ve yet to run into an issue! VERY happy with this thing!!
