Every once in a while, two appliances from the same brand create enough buzz that you can’t help but test them side-by-side. That’s exactly what happened with the Ninja DT251 and Ninja DT201, two powerful air fryer toaster ovens that look similar at first glance but feel noticeably different once you start using them in a real kitchen environment.
After spending quality time cooking, baking, reheating, and air-frying with both, I discovered key differences that genuinely impact daily use. Below is my full breakdown based on hands-on experience—not just specs on paper.
Key Difference Between Ninja DT251 vs DT201 Air Fryer Toaster Oven
The Ninja DT251 includes Smart Cook System technology, featuring a built-in digital thermometer that allows precise cooking without guesswork. The DT201 lacks this feature, making the DT251 the better choice for meat lovers and anyone who values temperature-controlled automation.

Design & Build Quality
Both ovens share the same sleek, elongated design that fits perfectly under cabinets. They feel sturdy, look modern, and don’t occupy as much counter space as their size suggests.
But the DT251 definitely feels more premium. The upgraded digital interface makes it easier to read settings at a glance, especially when multitasking in the kitchen.
The DT201, on the other hand, has a more traditional digital display. It works fine, but once you try the DT251’s interface, you’ll immediately notice the difference.

Ease of Use
I found myself naturally gravitating toward the DT251 because of the Smart Cook System. Being able to insert the built-in thermometer and have the oven automatically stop cooking when the food reaches your chosen internal temperature is a level of convenience I didn’t expect to value so much.
With the DT201, I had to rely on an external thermometer or visual judgement—something that works, but not with the same precision.
Cooking Performance
When it comes to actual cooking power, both models perform at an impressive level:
- Air frying is fast and crisp.
- Roasting delivers even browning.
- Baking provides surprisingly stable heat distribution.
- Reheating doesn’t dry out food like a microwave.
However, the DT251 takes the win for meat-based dishes. Steaks, chicken breasts, turkey, roasts—everything turned out more consistently cooked in the DT251.
The DT201 still cooks very well, but I had to manually check temperatures more often.

Functions & Presets
Both ovens include 10 functions:
- Air Fry
- Air Roast
- Bake
- Whole Roast
- Broil
- Toast
- Bagel
- Dehydrate
- Reheat
- Pizza
Functionally, they behave almost the same. The real difference is again the Smart Cook capability in the DT251, which transforms the roasting and baking experience into a more automated process.
Cleaning & Maintenance
Both models share the same easy-to-clean interior. The crumb tray slides out smoothly, and the accessories are simple to wash.
I didn’t experience any staining or buildup even after repeated high-heat usage. Ninja clearly designed these ovens with maintenance in mind.

Noise & Heat Output
- Noise levels are acceptable, and both units sound like standard convection ovens.
- They get hot on the exterior but not dangerously so.
- The fan cool-down cycle is almost identical.
Real-World Experience
If you frequently cook meats or host dinners, the DT251 becomes your kitchen assistant. The automatic “doneness sensing” is something I didn’t realize I would depend on.
If you just need a solid-performing oven for daily tasks—toast, pizzas, fries, chicken wings—the DT201 feels more than enough.

Conclusion & My Recommendation:
After using both ovens extensively, the winner for me is the Ninja DT251. The Smart Cook System isn’t just a marketing feature—it genuinely changes the cooking experience. The built-in thermometer helped me achieve perfect doneness levels without babysitting the oven, which felt like a luxury.
That said, the DT201 remains a fantastic choice if:
- you’re on a tighter budget
- you don’t cook meats frequently
- you prefer a simpler, more hands-on cooking method
But if you want a future-proof appliance that removes guesswork, ensures precision, and elevates your meals effortlessly, the Ninja DT251 is absolutely worth the extra investment.
