Ninja countertop ovens commonly provide multi-function cooking modes such as Bake, Pizza, Roast, Broil, Air Fry, Toast, Bagel, Dehydrate, and Reheat. Many models are marketed with 8-in-1 or 10-in-1 functionality covering these modes.
Some Ninja countertop ovens reach temperatures up to 450°F and include rapid preheat features—examples note a 90‑second preheat—along with cyclonic or high‑flow air technology designed to speed cooking and promote even results.
One Ninja French-door countertop model lists a 5‑qt air fry basket and specifically notes it fits up to 5 pounds of French fries.
Ninja pizza accessories commonly use a stone or stoneware cooking surface about 14 inches in diameter. Kits may also include tools such as a stainless‑steel pizza cutter.
Some larger Ninja countertop ovens can fit up to two 9x9 baking trays, bake about 20 cookies in one batch, and accommodate multiple slices of toast or bagel halves across a rack for batch baking.
