The Ninja Combi is a countertop oven that merges air fryer speed with the consistency and versatility of a convection oven. It features multiple cooking functions including Bake, Air Fry, Roast, Toast, Reheat, Broil, Proof, and Dehydrate — all in one compact device. With a large internal capacity and a three-level rack system, it’s built for multitasking. Great for family dinners, weekly meal prep, or cooking multiple dishes at once without firing up a full-size oven.
The Ninja Combi looks and feels premium. With its stainless steel body, large viewing window, and intuitive digital controls, it’s both stylish and functional. The interface is clearly labelled and includes presets for each function. The rack system is sturdy, and the crumb tray pulls out smoothly for easy maintenance. Despite its larger footprint, it’s still more compact than a traditional oven and fits under most standard kitchen cabinets.
The interior has enough space to cook a full meal for four. Think: a tray of roast vegetables on the bottom rack, chicken thighs in the middle, and garlic bread up top. It can hold a 12-inch pizza, a 5lb chicken, or an 8x8 baking dish. Dimensions: roughly 43cm wide, 37cm deep, and 30cm tall — bigger than an air fryer, smaller than a wall oven. If you batch cook or cook multiple components at once, the layout is a major plus.
Air Fry mode delivers beautifully crisp chips, vegetables, and protein without drying them out. Bake mode maintains a consistent temperature for even cookies or cakes. The convection fan helps ensure browning and circulation across all three rack levels. Toast and Broil modes are fast and efficient, making quick work of breakfast or grilled cheese. With preheat times under 90 seconds, it’s ready to go faster than a conventional oven.

The crumb tray, wire racks, and Combi tray are all dishwasher-safe. Wipe down the glass door and interior walls with a damp sponge or cloth. Avoid using harsh abrasives. Empty the crumb tray regularly and keep the fan vent clear. A full clean takes under 5 minutes after each use.

Unlike the AF400UK or DoubleStack, the Combi offers true multi-level cooking and oven-like function. It’s better for baking and batch roasting but doesn’t offer drawer separation. For cooks who want to replace their oven entirely or cook whole meals at once, it’s more efficient than a drawer-style air fryer.
If you want a single appliance that can air fry, roast, bake, toast, and more, the Ninja Combi Oven delivers. It’s large, yes — but also incredibly useful. It cooks fast, evenly, and in volume. A great pick for busy families, meal preppers, or anyone looking to get more from every inch of countertop space.
Both — it combines convection oven functions with air fryer technology in one appliance.
