Air fryers have boomed in popularity over the past cover of years, and the Ninja Foodi 6-in-1 Smart 10-qt. 2-Basket Air Fryer with Smart Cook System DZ550 is no exception to it. I've seen the Ninja Foodi 6-in-1 Smart 10-qt. 2-Basket Air Fryer without the smart cook system comes and goes with stock and causes a hive of activity during some of the most epic sales events - including Black Friday.
I'm a particular fan of the dual-drawer air fryers since you can cook so much in them, either at the same time or at different intervals. When I saw that one of the best air fryers is now available with a smart cook system, I just had to try it.
It's known as the Ninja Foodi MAX Dual Zone Air Fryer with Smart Cook System AF451UK in the UK and, other than the name difference is a pre-set for Max Crisp instead of Air Broil. It holds exactly the same spec as the US equivalent.
Although it isn't the cheapest air fryer you can buy, I do feel that it is worth the dollars. Had I been a newbie to air frying food, I would particularly recommend it for its ease of use; the cooking programs are easy to navigate, and the two cooking baskets are handy for cooking family meals.
You will need to eat the food as soon as you hear the 'beep' though, because there's no keep warm function, and you may find that you have to frequently adapt the pre-sets to suit your cooking requirements.
Jennifer Oksien (Jen) is the editor of Top Ten Reviews. She has tested and reviewed countless air fryers over the years and has particularly enjoyed trying out new foods to cook (or not to cook) in an air fryer during the process. Jen tested the Ninja Foodi 6-in-1 Smart 10-qt. 2-Basket Air Fryer with Smart Cook System in her home kitchen to cook snacks and dinners for a couple of weeks. She had the air fryer on the countertop alongside a selection of other small appliances.

Ninja Foodi 6-in-1: Price & availability
The Ninja Foodi 6-in-1 Smart 10-qt. 2-Basket Air Fryer with Smart Cook System has a list price of $249.99. It's available to buy directly from Ninja or through select resellers, including Amazon, Best Buy, and Target.
If you'd prefer not to have the smart cook system with a smaller cooking capacity, then you can save $70 by opting for the Ninja DZ090 Foodi 6 Quart 5-in-1 DualZone 2-Basket Air Fryer. In terms of the specs, it has five functions instead of six, but other than that, it's identical to the review unit we have here.
Ninja Foodi 6-in-1: Setup
The Ninja Foodi 6-in-1 Smart 10-qt. 2-Basket Air Fryer with Smart Cook System arrived fully assembled in a cardboard delivery box. When I say ' fully assembled,' I mean that I didn't have to screw anything together other than to slot in the crisper plates and plug in the smart thermometer.
Before I first used it, I hand-washed it. The two 5-qt non-stick cooking baskets and crisper plates are dishwasher safe, but I prefer to wash these components in air fryers by hand to protect the non-stick coating.
When it was all assembled and washed, I took a step back to admire it. It doesn't take up too much space on the countertop, but that's so long as you don't have a microwave, kettle, toaster, blender, coffee machine, and hob on the same side of a compact kitchen. The air fryer can replace a microwave, providing that you don't regularly heat liquids, and it can toast bread, so those are two appliances that it could replace if you're tight on space.
You'll need to ensure that the air fryer has plenty of airflow around it and that you can safely open the drawers without disturbing the weight distribution on the countertop.
Wherever you place it in the kitchen, though, it'll look just as smart as it can perform.
Ninja Foodi 6-in-1: Design
The Ninja Foodi 6-in-1 Smart 10-qt. 2-Basket Air Fryer with Smart Cook System isn't anything particularly special in design, apart from the smart cook system.
This rather intriguing feature allows you to achieve the perfect doneness of various food types—from steak to vegetables—by simply clicking the system to the side of the air fryer and inserting the probe.
The two drawers are another feature that sits neatly into the main carcass of the air fryer, which can be opened/closed with a sturdy handle. The drawers feel solid, and there's no resistance when opening or closing them.
Above the drawers is a digital display that displays six cooking functions: Air Fry, Air Broil, Roast, Bake, Reheat, and Dehydrate. For our UK readers, the Ninja Foodi MAX Dual Zone Air Fryer with Smart Cook System AF451UK has all these cooking functions except Air Broil, which has been replaced with Max Crisp.
Sized at 12.8 x 13.9 x 17.1 in (h x w x l) and weighing 19.8 lbs, it isn't much smaller than a microwave, but it looks a lot more refined in comparison—less boxy with more curves.
Ninja Foodi 6-in-1: Performance
The Ninja Foodi 6-in-1 Smart 10-qt. 2-Basket Air Fryer with Smart Cook System has six pre-sets and the flexibility to tweak the cooking time and temperatures. When I reviewed this air fryer, I used four out of six pre-sets air fry, roast, reheat, dehydrate, and the Probe function. The other pre-sets are Air Broil / Max Crisp and Bake.
The difference between these pre-sets is the cooking time and temperature, which can all be tweaked up to 464F/240C, and a cooking time of up to 1 hour 30 minutes.
Frozen fries were the food type I used with the 'air fry' pre-set. The time set was 20 minutes, set at 392F/200C. This felt like too long on a high heat, but I gave it a go nonetheless.
The result was that the frozen fries were brown and crunchy, airing on the side of burnt. I tried cooking the frozen fries again later in the week for 15 minutes at 356F/180C, which yielded a much better cooking result.
Intrigued by the prospect of roasting a chicken, I decided to roast one. You often hear not to cook this type of food in an air fryer, but I don't see why not because, as I found, it is possible.
There's the option to cook with Probe or by selecting the Manual button.
You can opt to 'Sync' with Probe or 'Match' with Probe. Sync means that you can program each zone and pair the Probe to finish at the same time, whereas Match means that you set Zone 1 with Probe and use Match Cook to automatically match settings to Zone 2. I went for 'Match' since I cooked the chicken outside of meal time for review purposes.
If using the Probe, you can select Small Preset or Large Preset, depending on the size of the protein you are cooking (chicken is large). Then, use the arrows on the left of the display to select the protein (pork, chicken, beef, or pork) and the arrows on the right of the display to set the internal outcome.
I tried out the Probe, but the pre-set to 'Roast' only went up to 158F/70C, and the manual only went up to 185F/85C. This isn't high enough to roast a chicken. I also found that when I selected this pre-set, it 'timed out' once it had reached temperature, so the chicken was still raw.
I circumvented this uncooked chicken issue by consulting the quick start guide. It displays a comprehensive cooking chart that suggests cooking a whole chicken at 338F/170C for 50 minutes. And this is what I did.
The results were good, albeit the meat was a little dry. The skin was also crispy, which is always a good sign, and all the juices ran clear, so it was cooked through. I was just really disappointed with the probe. Although it did recognize when it got up to temperature, this wasn't the right temperature, and it wasn't for long enough.
The reheat pre-set was a little too high and went on for far too long, in my opinion. It was set to 338F/170C with a temperature of 15 minutes; I only needed 5 minutes to reheat a few slices of pizza, so I tweaked this. However, the dehydrated pre-sets were pretty spot on for air-frying sliced vegetables. They lasted 6 minutes and were set to 140F/60C.
To note, the time and temperature of the pre-sets were set at:
- Max Crisp: 464F/240C for 10 minutes
- Air Fry: 392F/200C for 20 minutes
- Roast: 374F/190C for 15 minutes
- Bake: 320F/160C for 15 minutes
- Reheat: 338F/170C for 15 minutes
- Dehydrate: 140F/60C for 6 minutes
As I did when setting up the Ninja Foodi air fryer for the first time, I washed the basket and crisper tray by hand to preserve the non-stick. These parts are dishwasher-safe, though.
During the review process, I measured the noise level of the air fryer. According to the app I was using, it was recorded at 63dB, which is the equivalent of a 'quiet street', and I didn't think it was too loud at all.
A couple of things to note...
There is no 'keep warm' function, so you'll want to be ready to tuck into the air-fried food as soon as you hear the 'beep.' While there is the 'reheat' pre-set, I found that this isn't as convenient as a dedicated keep warm function, especially since it'll need tweaking.
The batter on fish fingers tended to stick to the non-stick. I didn't experience this when cooking frozen fries, vegetables, or chicken.
Ninja Foodi 6-in-1: User reviews
Customers on Amazon have given positive reviews of the Ninja Air Fryer. One customer commends the air fryer for being fast, easy to use, and quiet. She also appreciates the two separate large drawers that allow cooking different meals simultaneously and the non-stick coating of the drawers that makes cleaning easier. However, she mentions that the crisping plates in the drawers were initially difficult to remove.
Another reviewer describes the Ninja Air Fryer as one of the best air fryers they have ever used, noting that it heats up quickly and becomes easy to set up once you get used to the controls. D. Young finds the Ninja Air Fryer more accurate in temperature control and praises the meaningful cooking modes and the non-stick coating for easy cleanup.
A third reviewer finds the Ninja Air Fryer great, with good capacity, easy to use, and clean, and appreciates its quick cooking capabilities. Some minor criticisms include the containers' size and the crisping plates' initial tightness.
Would I buy the Ninja Foodi 6-in-1?
The Ninja air fryer offers a 10-quart capacity split between two 5-quart baskets, efficient cooking with a range of up to 464°F, and six cooking functions. It's ideal for families and versatile cooking. However, it lacks a keep warm function, and the pre-sets may not always deliver perfect results. You should also consider its size for smaller kitchens.

How does the Ninja Foodi 6-in-1 compare?
The Ninja Foodi 6-in-1 Smart 10-qt. 2-Basket Air Fryer with Smart Cook System is in a league of its own with its probe and dual drawer, making it very difficult to compare, but the air fryer that could tempt you away from it is the Ninja Foodi FlexBasket Air Fryer with 7qt MegaZone.
This new air fryer by the brand can turn one basket into two with a basket divider. I haven't seen an air fryer that could do this previously, so it's a revolution among the air fryer hype. As with the Ninja air fryer on test, it also has six cooking functions.
Of course, there is also the Ninja DZ090 Foodi 6 Quart 5-in-1 DualZone 2-Basket Air Fryer, which regularly sells out during big sales events and tops the lists of many air fryer buyers' guides. It doesn't come with a smart cooking system and has five functions instead of six, but other than that, it's identical to the review unit we have here.
If you don't need a dual-drawer air fryer or one with mega capacity, the single-drawer air fryers would be more appealing. The toughest competition for NInja air fryers is Cosori. All Cosori basket air fryers have single drawers, yet they boast decent capacities, such as the Cosori Pro III, which has a 6.8-quart capacity. These undercut the twin-drawer Ninja air fryers by almost $100, making them a serious rival to the Ninja brand.
How I tested the Ninja Foodi 6-in-1
- It was the only air fryer in my house
- Used for two weeks to cook snack and dinners
The Ninja Foodi 6-in-1 Smart 10-qt. 2-Basket Air Fryer with Smart Cook System was the only air fryer in my family home during testing. This means we used it a lot, especially at dinner time, as an alternative to the range cooker.
I air-fried fries, roasted chicken, and dehydrated vegetables. The pre-sets didn't work for me because they either burned or undercooked the food. Therefore, I tweaked the pre-sets to a time and temperature that I was used to when reviewing air fryers. These times and temperatures are also noted in the included instruction manual.
See more about how we test.
