Overview
Not a single-cavity toaster oven, the Ninja Double Oven uses its FlexDoor to split into a quick top oven and a larger bottom oven for convection and air frying. Smart Finish can time both so two dishes end together.
Two dishes at different temperatures that finish at the same moment is the reason to buy this Ninja. FlavorSeal stops smells crossing between the ovens. It is a large, heavy unit, and the listing never states its temperature range.
Who it's for
Busy family kitchens where dinner means a protein plus a side benefit most, since both ovens run at once. Cooks with little counter depth, or who mostly toast and reheat, will find it more machine than they need.
Pros and cons
- Two ovens with separate temperatures and times
- Smart Finish ends both dishes together
- Air fry basket included for the bottom oven
- Leave-in thermometer monitors doneness
- Large and heavy for a countertop
- Listed dimensions conflict, measure before buying
- Temperature range not listed
- Only a one-year limited warranty
Performance notes
Each cavity heats on its own, so results depend on matching the dish to the right side: the top oven for quick, thin items and the bottom oven with convection for roasts, bakes and air frying. The leave-in thermometer lets the Smart Cook System track food temperature, which matters more for doneness than the timer.

Frequently asked questions
What comes in the box with the Ninja DCT451?
Included components are the countertop oven, an air fry basket, a baking pan, a crumb tray and a wire rack. The title and description also name a leave-in thermometer, though it is not in the components list, so confirm it with the seller.
Can you use just one oven on the Ninja DCT451?
Yes. The description says you can use only the top rapid oven for snacks, sides and sheet pan meals, or only the bottom oven for larger roasts, bakes and air frying.
Is the Ninja Double Oven a microwave?
No. It is a countertop convection and air fry oven with two heated cavities, not a microwave.
Can the Ninja DCT451 replace a full-size wall oven?
Ninja claims 65% faster meal-making than a traditional oven by removing back-to-back cooking, but capacity is listed at 12 liters, so very large roasts may still need a full oven.
