How does it compare with a basket air fryer?

It holds far more and can bake, roast, toast and dehydrate, but a basket fryer usually crisps faster because the food sits closer to the heat. Pick this one if capacity and versatility matter more than speed.

Is the Pro Cook System worth using?

Yes for roasts and proteins. The probe plus presets cook to a target temperature instead of a timer, which owners say removes guesswork.

How much counter space does it need?

Plan for about 20 inches wide and 17 inches deep, plus clearance at the back for the rear heat source and door swing at the front.

Can it replace a toaster?

It toasts up to 9 slices at once, so for most households it can. Small single slices take longer than a slot toaster.

What comes in the box?

The oven, two wire racks and a food thermometer for the Pro Cook System.

Does it need preheating?

Ninja lists a 90-second preheat, and preheating helps even browning, especially for baking and air frying.

About the Ninja Prestige Smart XL Air Fryer & Countertop Oven with Pro Cook System

The Ninja Prestige Smart XL is a countertop convection oven and air fryer with a rear heat source, a smart surround convection fan and a built-in food thermometer tied to Ninja's Pro Cook System. It fits 9 slices of toast, runs from 180°F to 450°F and preheats in about 90 seconds, so it covers air frying, roasting, baking, dehydrating and toasting in one box. It suits households that want one appliance instead of a separate air fryer and toaster oven, and it is large: about 20 inches wide and 17 inches deep, so measure your counter first. Against basket-style air fryers it trades crisping speed for capacity and versatility; against plain toaster ovens it adds real convection and probe-guided cooking. Owners rate it highly overall, with the usual complaints about size and a learning curve.
