The Ninja Foodi DZ550 is a dual-basket air fryer that was launched in 2022. It offers a combined 10-quart capacity and is intended for preparing full meals for multiple people. It's a feature-rich model, with the option to cook completely different recipes in each basket and the ability to coordinate cook times so both recipes finish at the same time. It also comes with a built-in temperature probe, which is useful for cooking whole proteins, and it offers six cooking presets.
Our Verdict
The Ninja DZ550 cooks batches of frozen French fries very evenly. Its dual-basket design gives you ample surface area to spread food out, and its high fan speed and stable temperature help ensure that frozen fries, hash browns, and tater tots cook quickly and come out crispy and golden brown. That said, it struggles more with homemade fries, especially if you like chunky home fries or thick potato wedges. It cooks thicker foods with a higher moisture content, like fresh-cut fries, more slowly and leaves them crispy here and there, but not consistently across the batch. The dual-basket design also takes up a lot of space, which can feel like overkill if you're mainly using it for simple precooked sides, like frozen French fries.
Large surface area to spread food out for better airflow.
Evenly crisps frozen fries and hash browns.
Cooks small foods quickly.
Thicker wedges and fresh-cut fries cook slower and come out less crispy.
Bulky design; it’s hard to store, and monopolizes counter space.
The Ninja DZ550 has ample capacity for cooking large batches of chicken wings, but the result depends on what kind of wings you're making. It's excellent for precooked breaded wings, which crisp up quickly and evenly. Raw wings don't cook quite as well. The final product is tender and juicy on the inside, but doesn't have the crispy exterior you'd expect from a great batch of wings. Of course, you can cook them longer for a crispier finish, but they'll be quite dry by the time the whole batch browns properly.
Cooks fatty proteins without drying them out.
Large surface area to spread food out for better airflow.
Precooked and breaded wings brown quickly and evenly.
Struggles to evenly crisp moist foods.
Cooks moist foods slowly.
The Ninja DZ550 provides good air frying performance. It cooks simple snacks, like French fries and mozzarella sticks, very quickly and evenly. However, it struggles with raw proteins, especially those that need consistent, high heat for a quick sear. When you make a batch of fresh wings or drumsticks, for example, only a small amount comes out completely crispy, and one or two pieces don't crisp up at all. That said, they stay moist and tender, so you can expect better results with mains that are best cooked at a lower temperature, like pork chops, especially with the built-in temperature probe. Beyond these uses, it's a versatile option. You can use a low temperature and fan speed for dehydrating fruit or proofing dough, and use the high end of the range to broil the top of a mini mac and cheese or open-faced sandwich.
Evenly crisps batches of frozen fried foods.
Cooks small foods quickly.
Cooks fatty proteins without drying them out.
Broad array of settings makes it a versatile option.
Struggles to evenly crisp moist foods.
Cooks moist foods slowly.
The Ninja DZ550 has plenty of cooking space. As a dual-basket, 10-quart air fryer, it's meant for cooking full meals and larger portions. Together, the baskets have enough surface area to spread food out, allowing hot air to circulate evenly around your food.
Enough capacity to cook family-sized portions.
Sufficient surface area to arrange food in one layer.
The Ninja DZ550 preheats and cooks fries, chicken nuggets, and other small, fried snacks very quickly. It takes significantly longer when using both baskets to cook thicker proteins, like wings, drumsticks, or pork chops, since the air fryer only heats one basket at a time, switching between them as your food cooks.
Cooks small foods quickly.
Preheats quickly; start cooking in just a couple of minutes.
Cooks moist foods slowly.
The Ninja DZ550 is a large air fryer, which is expected since it has a family-sized 10-quart capacity.
Bulky design; it’s hard to store, and monopolizes counter space.

Popular Air Fryer Comparisons
The Ninja Foodi DZ550 is a large-capacity, dual-basket air fryer that comes with a built-in temperature probe. Ninja's dual-basket models offer strong performance compared to those from other brands. For instance, this model outperforms the Philips 3000 Series Dual Basket NA350/00, offering greater versatility and more even cooking for bite-sized frozen snacks such as fries and nuggets. While the DZ550 isn't the newest model on the market, it still stands out compared to dual-basket models from the same brand. It cooks more evenly than the newer Ninja DualZone DZ801, and cooks faster than the Ninja Crispi DualZone DD101, an air fryer from the brand with two glass cooking chambers.
That said, the DZ550 has one big downside. Using both baskets at the same time limits the maximum temperature to 400 °F and means that only one basket gets heat at a time. Consequently, whole proteins that need high heat for quick browning, like fresh wings, pork belly, or steak, don't crisp up enough. If you're looking for an air fryer that makes crispier recipes with whole proteins, and you need a lot of surface area, rather than two baskets, consider the Typhur Dome 2, which leaves more of each batch crispy.
If you're wondering what we recommend, check out our list of the best air fryers, the best large-capacity air fryers, or the best air fryers for French fries.
The Ninja DualZone Pro DZ950 and Ninja Foodi DZ550 are both large dual-basket air fryers, and they perform similarly. The DZ950 offers better frying quality, producing more consistently crispy results, and it holds its temperature more steadily throughout a cook. The DZ550, on the other hand, has slightly more room in each basket if you regularly spread food out in a single layer. Both include a built-in probe that tracks internal temperature so you can cook proteins to a specific doneness without guessing, and both take up a similarly bulky footprint given their dual chambers.
The Ninja Foodi DZ550 and the Our Place Wonder Oven Pro have different form factors and strengths, and you may prefer one over the other based on your needs and the kind of food you cook most. The Ninja is a dual-basket model that excels at making frozen fried snacks and sides like fries, onion rings, and mozzarella sticks. It cooks foods like these faster and leaves more of each batch crispy and golden brown. The Our Place, on the other hand, is a toaster oven-style air fryer that cooks thicker proteins like wings, pork chops, and steak faster and more evenly. The Our Place can reach a lower temperature, making it more suitable for baking and dehydrating, but the Ninja has a higher maximum fan speed, which is helpful for roasting and air frying.
The Ninja Foodi DZ550 and the Ninja Crispi DualZone DD101 are both dual-basket models, but the Crispi has two glass cooking chambers, while the Foodi has a more typical design. While the Foodi provides slightly better performance overall, both air fryers have something to offer, and you can decide largely based on the design you prefer and what you cook most often. The Foodi cooks more evenly when it comes to simple air fryer staples, like frozen fries and mozzarella sticks, and it finishes cooking faster. However, the Crispi comes out ahead when you're using both baskets to cook whole proteins like wings or steak, leaving each batch crispier than with the Foodi. The Crispi's cooking chambers also double as storage containers, saving time on clean-up.
The Ninja Foodi DZ401 and the Ninja Foodi DZ550 are both great options, but the DZ550 is a slightly better choice. Its biggest advantage is frying quality; the DZ550 leaves more of your food crispy and well-browned. It also preheats and cooks slightly faster, and it's more versatile. That said, it's also the more expensive option, but not by much, so the difference will be worth it for most people.
Test Results
Individually, the baskets aren't particularly roomy, but using them together gives you ample surface area for arranging food in a single layer. The crisper trays have a ceramic coating, which you might prefer if you avoid PTFE coatings, but it also makes them harder to clean by hand.
Between the two baskets, this air fryer has a large 10-quart capacity, enough to serve five or more people at once. They're tall enough to fit most commonly air-fried foods, though there may not be quite enough space for taller foods like stuffed peppers or bakery-style muffins.
If you don't mind a slightly smaller cooking capacity and prefer glass over plastic, consider the Ninja Crispi DualZone DD101, which has two fully isolated glass cooking chambers.
This is an amazingly versatile air fryer. Thanks to its dual-basket design, you can cook separate foods in each basket using different settings. The Smart Finish setting coordinates cooking for the baskets, so both sides finish cooking at the same time. When you use only one basket, the maximum power draw is 1445 W.
Unlike most air fryers, it comes with a thermometer you can use to monitor the doneness of proteins, such as a steak or chicken breast, as they cook. You can either enter the protein's size and type (chicken, beef, pork, or fish) to have the air fryer automatically determine when it's done, or manually enter the internal temperature you want your food to reach.
Otherwise, it offers a range of fan speeds and temperature settings for different recipes and cooking methods. It reaches 450 °F at its maximum temperature, which is hotter than some air fryers, and its minimum temperature is suitable for dehydration.
- Air Fry: 300 °F – 400 °F, 1 – 60 minutes
- Air Broil: 400 °F – 450 °F, 1 – 30 minutes

- Bake: 250 °F – 400 °F, 1 – 4 hours (Time is adjustable in one-minute increments up to one hour and in 50-minute increments beyond one hour.)
- Reheat: 270 °F – 400 °F, 1 – 60 minutes
- Dehydrate: 105 °F – 195 °F, 1 – 12 hours (Time is adjustable in 15-minute increments.)
This model air-fries small, simple snacks and sides like fries, onion rings, and mozzarella sticks very evenly, leaving most of each batch crispy and golden brown. By the time most of your food is cooked through, just a small portion is still mushy, while one or two pieces burn.
This air fryer is okay for cooking meat and poultry. The biggest issue is for recipes that need to use both baskets to maximize surface area, like chicken wings. Using both baskets limits the maximum temperature to 400 °F overall, and the air fryer switches power between individual heating elements, so only one stays on at a time. As a result, most wings come out inconsistently cooked, with browning on only one side. That said, they stay moist and tender throughout the process, so if you're cooking proteins that do better with lower temperatures, like pork chops, you can expect better results. By contrast, if you need to cook at high heat for something like broiling steaks, you'll need to cook with just one basket for best results. Finally, there's a built-in thermometer, making it easy to cook meat to a specific temperature.
Using one basket to make a small snack or a side of fries is very quick. However, using both baskets or cooking more substantial foods, like a batch of wings or drumsticks, takes significantly longer.
It has very good temperature stability. It returns to temperature quickly after you open the drawer to add food. It also maintains a stable temperature during cooking, although it tends to slightly overshoot the selected temperature.
