Room To Roam

      Ninja did a great job designing the interior space and convection fan for optimum circulation, like in previous models. As a result, the heated air circulates evenly, regardless of which tray(s) you’re using.

     No need to constantly remove and rotate trays, so your overall cooking time is shortened, too. This is especially important with two or more trays, making air frying, baking, dehydrating, and toasting much more efficient overall.

Cook Smarter, Not Harder

     Just like most Ninja kitchen appliances, the Foodi Smart XL Pro is packed with smart features that make life simple. If you can read a recipe book, then you can execute meals like a professional chef.

     The coolest smart feature is the convection fan regulator for multi-speed circulation. Of course, it’s not as sexy of a feature as the smart thermometer, digital display panel, or other bells and whistles. But, on the other hand, it’s the function that makes that biggest difference in EVERY cooking mode.

Controlled Environment

     The control panel and digital display may look intimidating at first, but the menu setup is very intuitive. For example, after you select what you’re cooking and how you want it cooked, it even shows which rack position to use for best results.

     The thermometer is icing on the cake. Taking all of the guesswork out of roasting, it even switches to “keep warm” mode when the internal target temperature is met.

Trail Mix Connoisseur

     The multiple infrared heating elements are powerful yet precise. Able to reach a minimum temperature of 85°, the Ninja DT251 allows you to dehydrate to perfection.

     Even though it only comes with one dehydrating rack, you can purchase extra. Then, using all four rack slots, you’re able to take full advantage of the XL capacity.

     Dehydrate extra seasonal fruits for later, or create your own homemade trail mixes. You can even make your own beef jerky, venison jerky, or other dried meats.

     With a 17.09″ x 20.22″ footprint, this is only for kitchens with extra counter space. The only other major downside is that it doesn’t have a rotisserie function, but that’s about it.

     The Ninja Foodi Smart XL Pro is perfect if you’re looking for a healthier and tastier alternative to a microwave.

     If you can survive without microwave popcorn, you won’t miss a thing. Plus, leftovers never tasted better.

     Since it cooks around 30% faster than conventional ovens, it’s also a great tool to help with large meals. No more waiting for the oven to be free to toast the bread or bake dessert. But, of course, with the smart thermometer, you’ll probably end up using the Ninja DT251 to do the main course anyway.
