In recent years air fryers have become a necessity in any kitchen, home or professional. They are a great way to cook food without all of the added oil. Two of the most popular air fryer brands on the market today are the COSORI and Ninja air fryers.

Both are great options, each one with its unique set of features, but which one is better? We have done a side-by-side comparison, to help you decide which one is right for you. We have focused on the two most popular large-capacity models – Ninja Foodi DZ401 10qt DualZone and COSORI 6.8Qt, Dual Blaze.

Short Overview

Ninja Foodi 6-in-1 DualZone XL DZ401

The Ninja Foodi DZ401 is a 6-in-1 air fryer that can do it all, from air-frying to baking, reheating and dehydrating. The large 10-quart capacity is perfect for feeding a large family or crowd. The 2 baskets and the DualZone feature lets you cook two different foods at two different temperatures simultaneously, making it the perfect air fryer for cooking a variety of foods.

COSORI 6.8Qt Dual Blaze

The COSORI 6.8Qt Dual Blaze features dual heating elements and patented automatic temperature control that makes real-time temperature adjustments during cooking. It also has as many as 12 customizable functions and the smart control via VeSync app lets you control your air fryer remotely, monitor cooking progress, and activate voice control with Amazon Alexa and Google Assistant.

Cooking Features

Ninja Foodi XL has 6 cooking programs: Air Fry, Air Broil, Roast, Bake, Reheat, and Dehydrate. The most interesting is the Air Broil feature that supposedly cooks the food as you would in an oven, on a broil setting. This is great for cooking meats and other foods that need a lot of heat for that crispy top crust. You can also manually set the cooking temperature from 105°F to 400°F in 5-degree increments.

The Ninja Foodi also stands out for its DualZone feature which allows you to cook two different foods at two different temperatures simultaneously. This is a great feature if you want to cook an entire meal at once.

The COSORI Dual Blaze also features patented automatic temperature control that makes real-time temperature adjustments during cooking. This is a great feature if you want to ensure that your food is cooked evenly.

Both the Ninja Foodi and the COSORI have a “reheat” function that will reheat your food without overcooking it. This is a great feature if you want to reheat leftovers or cook frozen food.

The COSORI 6.8Qt also has 6 one-touch programs: steak, poultry, seafood, shrimp, bacon, and frozen food. You can also manually set the cooking temperature from 180°F to 400°F. The COSORI also has a “keep warm” function that will keep your food warm for up to 60 minutes after cooking.


When it comes to cooking, both the Ninja Foodi and the COSORI air fryers perform exceptionally well. They both use advanced technology to circulate hot air around the food, cooking it evenly and quickly. The COSORI does have a slight edge when it comes to cooking times, as it is able to reach higher temperatures faster than the Ninja Foodi.

Cosori Dual Blaze has two heating elements, one on the top and one on the bottom. These elements distribute heat at varying temperatures at different times during cooking. This makes the air-frying process more refined while eliminating the need for shaking or flipping.

The Ninja DZ401 can cook two dishes in two different ways at once, but it also features the Smart Finish feature. This allows the air fryer to automatically adjust the cooking time and temperature, based on what you are cooking, so that all the food is done at the same time. This is very useful when cooking a meal with multiple dishes. It is quite large, but if you need an air fryer that can fit a whole chicken, take a look at some of the models with a rotisserie feature.

Capacity and Size

The Ninja Foodi DZ401 has a 10-quart capacity, making it one of the largest air fryers on the market. However, be aware that this is divided into two baskets, 5-quart each. The COSORI 6.8Qt air fryer is smaller, with a 6.8-quart capacity, but it is a single basket air fryer.

Both units have square baskets, which offer more space than a round basket. The Ninja Foodi has two 5-quart baskets, while the COSORI basket is 6.8 quarts. The difference in size is not that significant, but it may be important if you have a large family or often cook for large crowds.

Speaking of the footprint, the COSORI is a bit taller and deeper than the Ninja Foodi, but it’s also narrower, as Ninja has two baskets to accommodate. Look for exact dimensions in the comparison table below.


Beauty is in the eye of the beholder, but we cannot overlook that Cosori was the winner of several design awards last year, including Red Dot, IF Design, and Good Design for the COSORI 5.8Qt Air Fryer. It is easy to see why – the sleek, minimalist design with stainless steel housing is not only beautiful but functional as well. This model might not be as sleek, but it still can be a nice addition to your kitchen.

The Ninja DZ401, on the other hand, is more of a traditional air fryer design. It has a large, square body with a gunmetal grey matte finish and chrome-looking basket handles. We really loved the look of this unit, but it might not be the right fit if you are looking for a more modern design.

Ease of use and cleanup

The Cosori 6.8Qt Dual Blaze is very user-friendly with its one-touch digital control panel. The Ninja DZ401 also has a user-friendly control panel, but it does have more buttons and options, which might be overwhelming for some users.

Both models have dishwasher-safe removable parts, but the Cosori 6.8Qt Dual Blaze has a removable inner pot that makes cleanup even easier.

The Ninja DZ401 is more expensive than COSORI 6.8Qt, priced at $199.99, but it is pretty much two air fryers rolled into one. The COSORI 6.8Qt air fryer is priced at $139.99, and it offers some high-tech features for the price, including the app that turns this air fryer into a true smart home appliance and voice control via Alexa or Google Assistant.

Which one is better?

Between Ninja and COSORI air fryers, it really comes down to personal preference. With 2 baskets and completely separate temperature controls, the Ninja DZ401 is practically two 5qt air fryers in one. It is great for cooking an entire meal for the whole family, cooking two different items at two different temperatures.

COSORI 6.8Qt Dual Blaze is not as large, but it boasts advanced cooking features that make it worthy of a professional kitchen. If you are looking for an air fryer with a larger capacity, but only need one basket, the COSORI 6.8Qt Dual Blaze is a great option. It has a smaller footprint and it’s also cheaper than Ninja DZ401.
