Why Cook in One Oven When You Can Cook in Two?

Enter the Ninja DCT451 12-in-1 Smart Double Oven with FlexDoor™ — a countertop powerhouse that’s more than just an oven. It’s your new secret weapon for feeding everyone, fast, without sacrificing flavor or sanity.

What Makes This Oven So Smart?

FLEXDOOR™: Two Ovens in One

This isn’t your average toaster oven. The FlexDoor™ design gives you two completely separate cooking spaces in a single unit. Open just the top for snacks and quick bakes—or open both to run two different meals, at the same time, without overlap.

FLAVORSEAL™ Technology

Tired of garlic bread tasting like fish? Same. With FlavorSeal, smells and flavors stay in their own zones. That means crispy fries in one oven, tender salmon in the other—and no crossover drama.

SMART FINISH™: One Oven Brain, Two Dishes

This is magic: even if you’re cooking at different temps and times, Smart Finish™ syncs both ovens to finish at the same time. Perfectly coordinated meals—without mental gymnastics.

BUILT-IN SMART THERMOMETER

Just stick the leave-in thermometer in your protein, and let the oven take it from there. The Smart Cook System keeps tabs on temperature with pro-level precision, so no more guesswork.


12 Cooking Functions, Unlimited Possibility

You’re not just getting an oven—you’re getting a full cooking suite on your countertop:

  • Top Rapid Oven: Bake, broil, toast, bagel, reheat, keep warm
  • Bottom Air Fry Oven: Air fry, convection bake, pizza, air roast, whole roast, dehydrate

Whether you’re crisping wings or slow-roasting vegetables, it’s got a mode for every mood.

Customers Promising Reviews: “We use this double oven more than our conventional oven. The independent compartments allow two things to be cooked at the same time. The “Smart Finish” option will allow the oven to decide when to start a 2nd dish so the two finish at the same time.” –

“Having used a smaller Ninja digital air fryer pro for almost 5 years, i wanted to update to allow larger baking spaces while staying on side of my kitchen counter. This oven fits the bill.  Clean up is a breeze as well as long as you wipe it down after each use. Very glad I upgraded to this terrific appliance.” –
