Though it’s an air fryer, the Ninja Speedi is greater than that: constructed to ship multi-level cooking, this machine can dish out full meals in simply quarter-hour, in addition to grilling, steaming and, after all, air frying.

It doesn’t have a conventional air fryer’s highest temperatures, however if you happen to extra need a machine that delivers versatile cooking, the Speedi is a good alternative.

Design and Options

  • Two cooking modes
  • Crisper plate could be positioned in two places
  • Steams in addition to cooks

From the surface, the Ninja Speedi appears very similar to the corporate’s different air fryer/grill mixture merchandise, such because the Ninja AG651UK. In fact, the Speedi, regardless of the concentrate on its 15-minute meals, is an analogous product in most regards.

The distinction comes from how the Speedi can be utilized. Flip open the lid and there’s a 5.7-litre cooking pot, which makes this a bigger air fryer than many. On the backside of the pot sits the detachable crisper plate, which is used for air frying.

The usual place is to have this crisper plate on the backside, which works for normal air frying. On this approach, the Speedi is much like most air fryers. I did discover that it was simpler to make use of silicone tongues to show meals, because the pot is somewhat onerous (and scorching) to take away and shake.

Take the crisper plate out and also you’ll see that it has fold-out legs that allow it stand midway up the pot. That is the second cooking place, and lets the Speedi cook dinner on two ranges: the underside stage is in your base (pasta, rice, potatoes and something you’d wish to cook dinner in liquid), and the highest stage is for protein, crisped up with the grill.

That mixture means you may cook dinner two several types of meals directly, giving an entire meal with little or no problem. My solely minor criticism is that the crisper plate is a bit fiddly to take away to get to the underside layer: I discovered utilizing a pair of insulated rubber oven gloves was one of the simplest ways.

Utilizing the Speedi is straightforward. On the prime is a swap that strikes the Speedi between its Fast Cooker and Air Fry / Hob settings. For Fast cooking, there’s a alternative of Speedi Meals, Steam Air Fry, Steam Bake and Steam. All of those require some liquid within the backside, however the fast begin information helps make the selection straightforward.

For the Air Fry / Hob setting, there’s a alternative of Grill, Air Fry, Bake / Roast, Dehydrate, Sear / Sauté and Sluggish Cook dinner. Once more, the superb information helps select the proper settings and tough cooking instances for varied widespread meals.

Utilizing the Speedi is straightforward. With a mode set, it’s a matter of setting the goal temperature after which the cook dinner time. For any choice involving steam, there’s a pre-heat part earlier than the primary cooking time is began; common modes simply begin the timer mechanically. For the latter, I wanted so as to add a couple of minutes to the cooking time, in comparison with an air fryer with a pre-heat perform.

On the finish of cooking, every thing is dishwasher protected, though it’s simply as straightforward to manually wash every thing up.


  • Doesn’t have the very best temperatures
  • Steam air frying is sensible
  • Makes advanced meals straightforward to cook dinner

The Ninja Speedia can be utilized as a daily air fryer, nevertheless it tops out at 210°C and doesn’t have the upper warmth modes that some rivals have. Cooking hash browns, I acquired good outcomes, however the last product wasn’t fairly as crispy as when utilizing a 240°C mode on the Ninja AF400UK.

I then moved on to cooking chips. An air fryer can dry out chips, however the steam air fry mode on the Speedi is sensible. Utilizing 125ml of water, I took parboiled Désirée potatoes, sliced into skinny chips, and cooked for 25-minutes at 200°C (turning as much as 210°C for the previous few minutes). The outcome was among the finest chips that I’ve ever had: crispy on the surface and gentle and fluffy on the within.

Subsequent, I moved on to multi-level cooking. I made some halloumi kebabs, coated with a soya sauce-based dressing and positioned these on the highest stage. On the underside stage, I put 200g of rice with 500ml of water, and set a cooking time of 15-minutes at 180°C.

With this cooking mode, the crisper plate can’t simply be eliminated to test how the underside layer is cooking, so that you sort of must belief that it’s cooking properly: be sure you have sufficient liquid within the backside to stop drying out. If there’s liquid on the finish, the sear perform can be utilized to complete off.

Secondly, the highest layer can cook dinner sooner than you could count on. I discovered that my kebabs had been cooked a couple of minutes earlier than the underside layer was, so wanted eradicating earlier. Even so, for a mid-week meal, it took 20 minutes (together with prep) and a single pot to supply one thing that may in any other case have required a number of pots and grills.

I used to be proud of the ultimate outcome. The liquid from the kebabs drips by way of onto the rice somewhat, so simply remember that what you cook dinner on prime will barely come by way of to the underside layer. That shouldn’t be a difficulty, as it’s one meal that you simply’re making.

Total, my kebabs had been good and crispy and the rice fluffy sufficient: certain a correct rice cooker will get the perfect outcomes for rice, however right here I’m prepared to sacrifice the perfect outcomes for the comfort that the Speedi affords.

I additionally like the pliability. One night time, I used the underside layer to cook dinner rice. In the direction of the top of the cooking interval, I added some pre-cooked onions, pepper and sliced steak, reheating them. As soon as completed, I eliminated half of the rice, and used that with a Thai inexperienced curry.

With the remaining rice, I added soya sauce and the heated onions and peppers, utilizing the sear perform to complete off the meal, and gave that to my daughter who doesn’t like the warmth of the curry. That was then two totally different meals, utilizing some shared components, cooked with the minimal stage of fuss.
