Ninja Foodi 14-in-1 Pressure Cooker FD401 Review (2026)

Why you should trust this review

I bought this Ninja Foodi FD401 at retail and ran it as a working appliance in my kitchen for eight weeks. Ninja did not provide a sample, did not see my notes, and had no idea I was testing it. That matters here because the FD401 is sold on a promise that is very easy to fudge in marketing copy: fourteen functions in one box. My job was to find out how many of those functions are genuinely useful and how many are just time and temperature presets dressed up with a label.

I went in skeptical of the dual-lid concept. My biggest worry was that a machine trying to be both a pressure cooker and an air fryer would do neither one well. I ran it alongside a standalone 5.8-quart basket air fryer and an Instant Pot Duo 7-in-1 so I could put identical ingredients into competing machines and taste the difference directly rather than guess at it.

How we evaluated

Over eight weeks I cooked more than 40 distinct recipes across the FD401’s function set. For pressure cooking I ran my standard chicken broth protocol, raw carcasses, aromatics and six cups of water, six separate times, logging time to pressure, cook duration and natural release on each run. For air frying I cooked wings, frozen fries and Brussels sprouts in both the Foodi crisping lid and the standalone basket at matched weights and temperatures.

I tested the reversible rack with pot-in-pot cooks, eggs and rice on two levels at once, and I confirmed the safety valve behavior the same way I do on every pressure cooker I review, checking that overpressure protection engages before the sealing ring distorts. I also ran the dehydrate function on apple slices at 135F for eight hours to see how steady the temperature held over a long, slow cycle.

Pressure cooking that keeps up with a dedicated cooker

This is the test that decided whether the rest of the machine mattered. If the dual-lid design compromised core pressure performance, the whole concept would fall apart. It did not. Chicken broth from a cold start came up to pressure in ten minutes and completed a 25-minute cycle, putting active cook time at 35 minutes before natural release began. Total elapsed time from cold start through natural release was 56 minutes, which is statistically identical to the Instant Pot Duo running the same recipe.

Seal integrity was excellent across all six broth cooks. The sealing ring seated firmly every time and showed no deformation through the test cycles. The float valve released cleanly after every cook with no sticking, even after the fattiest broth run, which is where cheaper cookers tend to gum up. Quick release ran about two and a half minutes from full pressure, and natural release after a full broth cycle averaged 21 minutes, again right in line with the Instant Pot.

The air fryer lid is the reason to choose this machine

If the pressure side merely matches the competition, the crisping lid is where the FD401 pulls ahead. Chicken wings cooked at 400F for 22 minutes came out with skin measurably crisper than the standalone basket fryer at the same settings. I ran a small blind tasting with three people, and the Foodi wings won four of six rounds. The heating element in the crisping lid runs hotter and more evenly than I expected from an integrated design that has to share a body with a pressure cooker.

Frozen fries were crisp in 18 minutes and Brussels sprouts caramelized well at 380F over 15 minutes. The dehydrate function was a genuine surprise, holding temperature within about five degrees of target across the full eight-hour apple run, which is tighter than some standalone dehydrators I have used at a higher cost. None of this felt like a checkbox feature. The crisping lid does real work.

Slow cooking, pot-in-pot, and the menu friction

Slow cooking on low held an average of 148F over a four-hour pulled pork test, and the texture was comparable to the Instant Pot Duo’s output, though honestly I preferred pressure cooking the same cut in 45 minutes. Pot-in-pot cooking with the reversible rack worked, eggs and rice came out correctly on both levels, but loading the rack at full 6.5-quart capacity with two levels is tight and takes coordination. It is functional, not graceful.

The one real friction point is the 14-function menu. The digital interface makes you cycle through modes to reach the less common functions, and the labeling could be clearer. Expect to keep the manual handy for the first several uses. After about a week it became muscle memory, but the learning curve is real and worth knowing about before you buy.

Who should buy the Ninja Foodi FD401?

Buy it if you genuinely want a pressure cooker and an air fryer in one machine and you are willing to give up counter space and accept the bulk of two lids. The dual-lid system adds depth, and this takes up more room than any other cooker I compared, so a tight counter is the one thing that should give you pause. If you were already planning to buy both a pressure cooker and an air fryer, the Foodi is cheaper and better than owning two separate appliances, and it replaces them without a meaningful performance compromise on either side.

Skip it if you only ever pressure cook. In that case you are paying for a crisping lid you will never use, and a plain Instant Pot Duo does the pressure work for less money and a smaller footprint. The FD401 only earns its keep if you actually use more than one of its modes.

The verdict

After eight weeks and more than 40 recipes, the Ninja Foodi FD401 is the most versatile multi-cooker I have tested, and the rare one where the function count is not just marketing. The pressure cooking is as fast as a dedicated machine, the air fryer lid crisps better than a standalone basket, and the dehydrate function punches above its weight. The menu navigation takes a few uses to learn and the footprint is real, but if you want one machine to replace two and you use both modes, this is the one I would tell you to buy.
