Our take on the Ninja 12-in-1 Smart Double Oven with FlexDoor DCT451

The Ninja DCT451 is a countertop double oven with two independent cooking zones stacked in one unit. Its FlexDoor lets you open just the top compartment or the full door, so you can run two different dishes at different temperatures at once. It reaches 500°F, preheats in about three minutes and covers air fry, bake, broil, toast, reheat, dehydrate and keep warm across 12 functions. It suits households that want oven and air fryer capacity without giving up counter space, though the glass door gets very hot and the unit is heavy for a countertop appliance.

Questions and answers

Can the two ovens cook at different temperatures at once?
Yes. The top and bottom compartments have independent temperature and timer settings, so you can roast in one and bake in the other.
What does the FlexDoor do?
It lets you open only the top oven door or the full door. That keeps heat in the bottom oven when you check on the top dish.
How hot does the outside get?
The glass door can reach about 270°F, so it is not cool-touch. Keep hands and children away from the door during and after cooking.
What can it cook besides baking?
It air fries, broils, toasts, reheats, dehydrates and keeps warm, with 12 functions in total and a maximum of 500°F.
What comes in the box?
The oven, a wire rack, a removable crumb tray and a recipe booklet.
Is it a replacement for a full-size wall oven?
No. It is a countertop oven for everyday meals and sides. Its two small compartments suit smaller dishes rather than a large roast or a full turkey.
