In general, the food is delicious. Not only does it taste good, replenishes you, but it also makes you happy. One specific type of food that is very special and extra delicious is fried food. Just imagine taking a bite out of a fried chicken wing, a perfect roast, or some tasty onion rings. Imagine that crunch. Doesn’t it bring a smile to your face? However, fried food can also be unhealthy since there’s a lot of oil used for preparing it. But, what if there was another–healthier–way of making that flavorsome chicken? Well, with the help of air fryer ovens this is truly possible. 

Air fryer ovens use really hot air and fans to process the food. The air is moved around until the food is cooked and done. They give your meal a nice fried finish with minimal oil use or the need to have a deep clean afterward. Moreover, they can serve as a perfect replacement for microwaves. Again, much healthier.

With this in mind, I’ve chosen two fantastic fryer ovens from Ninja to review and compare to help you choose and start making finger-licking meals. Those will be the Ninja DT201 vs. DT251. Both are fantastic, but let’s see what each has to offer.

Ninja DT201 vs DT251 – Similarities


Like any oven, these two fryer ovens have to be powerful to work properly and prepare food daily. That is why both the Ninja DT201 and DT251 have 1800 watts of power. This wattage makes these Ninja air fryer ovens one of the strongest on the market. Also, you can prepare almost any meal because of this feature.

Cooking Functions

One of the best features that come with both of these Ninja products is the cooking functions. You get not two or five, but ten options for cooking. They are the same and include the following: air fry, air roast, whole roast, dehydrate, pizza, bake, toast, broil, bagel, and reheat. As you can see, you will be spoiled for choice. You can bake pies as well as roast. Moreover, you can use the Ninja oven to preheat leftovers. 


Compared to regular ovens, Ninja fryer ovens are smaller. Nevertheless, they have an excellent capacity for such size. In both, you can roast a turkey of up to 12 pounds, which is more than enough. Additionally, you can prepare two different meals in two pans, thanks to the ovens’ capacity.

Display Handle

An exciting feature, the display handle can be found on the Ninja DT201 and Ninja DT251. On it, you will find all the buttons and controls. Plus, the display showing the time and cooking settings are also on the handle. When you open the oven, the display settings freeze to avoid any changes to the cooking function settings. 

True Surround Convection

Now, the most important feature of these ovens is the true surround convection they have. This means that they have a super strong fan and top-to-bottom ventilation that spins the hot air throughout the entire oven. This process creates even cooking, which results in crisp finishes.

Differences between Ninja DT201 vs Ninja DT251

Smart Cook System

What’s fantastic when it comes to the Ninja DT251 is that it comes with a smart cook system. The system represents that the fryer oven has an integrated thermometer that continually measures your food’s doneness. Thanks to it, you won’t have to guess how much longer you will have to wait for your food.


Speaking of smart cooking, the thermometer you get on the Ninja DT251 can be used either manually or preset to a specific temperature. This is done via buttons found on the display handle. Unfortunately, the Ninja DT201 doesn’t have this option.

Value for Money

Both of these ovens are good. They come with so much in such a small package for an actual oven. Plus, they double as microwaves. What’s not to love about this? But what are their values, and are they worth the buy?

Ninja DT201

All in all, Ninja DT201 is a fantastic kitchen tool. You are offered ten cooking functions, accessories, a great airflow system. The only disadvantage it has is the lack of an integrated thermometer. However, you can do without it if you just buy one separately, or, perhaps, you already have one in your kitchen.

Ninja DT251

Now, this air fryer oven is the full package. You have all the features for cooking, including the smart cook system that gives you the thermometer, which doesn’t leave you guessing how done your food is.
