The Ninja 3-in-1 Cooking System does not come with an in-box cookbook. Ninjakitchen.com does, however, feature recipes for use with its cooking system, and Ninja cookbooks are available for purchase on Amazon.com.
Some recipes from Ninja's website include hearty skillet lasagna and apricot and country mustard salmon. Amazon.com sells books such as "Ninja Cooking: Easier Healthier and Better" that highlight the Ninja cooking system's ability to reduce the amount of oil and fat in food.
The Ninja Kitchen cooking system features a triple-fusion heating system that turns this kitchen gadget into a steam-infused oven or a conventional slow cooker. Chefs can switch between three different functions to complete multi-step dishes with the same appliance.
