Ninja Prestige Smart XL countertop air fryer oven DT501: A Full Review

My full-size oven feels silly on nights when I am reheating pizza, browning frozen fries, and baking a small tray of cookies after dinner. The Ninja Prestige Smart XL is the kind of countertop oven that can realistically take over a lot of those jobs, not just sit there for toast.

What stands out most is the size. This is not a tiny basket air fryer pretending to be an oven. It can handle two 9x9 pans, a big batch of cookies, several slices of toast, or even a small turkey, which makes it useful for families or anyone who cooks in batches. The 90-second preheat is also easy to appreciate on weeknights, and the convection setup does a good job getting fries, chicken pieces, and roasted vegetables crisp without constant shaking.

If I were making a 2026 best air fryer oven shortlist, this would be on it for capacity and versatility. The 10 cooking modes cover the basics I actually use: air fry, bake, toast, reheat, pizza, broil, and roast. Toast is more even than many toaster ovens I have used, though you still need to learn your preferred shade setting.

The tradeoff is that it is large and not cheap at about $230. It also is not as simple as a dial-only toaster oven, so there is a small learning curve. Still, for someone who wants one countertop appliance to air fry, bake, roast, and reheat without firing up the main oven, it makes a lot of sense.
