Ninja Speedi 12-in-1 Multi-Cooker Air Fryer & Slow Cooker ON500UK

The Ninja Speedi's most practical trick isn't the air frying or the slow cooking — it's the ability to cook a complete meal in a single pot using what Ninja calls Speedi Meals, where steam-cooked grains or pasta sit beneath air-crisped protein simultaneously. That one function alone removes the main frustration of weeknight cooking: timing two or three components to finish at the same moment. If you've been wrestling a frying pan, a saucepan, and an oven tray every Tuesday evening, this machine directly solves that problem in a 5.7-litre footprint.

Who Is This For?

This is built for one- to three-person households who cook from scratch regularly but resent the washing-up and the mental load of managing multiple hobs simultaneously. It also suits anyone in a flat or rental where oven use is expensive or inconvenient — the claimed 55% energy saving over a conventional oven is plausible given the smaller cavity and shorter cook times. If you regularly cook for four or more people, the capacity will frustrate you and you'd be better served looking at our best Ninja deals roundup where larger models are tracked.

What Buyers Say

Owners consistently praise the Speedi Meals function as genuinely fast and reliable, with rice and chicken dishes cited repeatedly as standout results. The air fryer basket also draws strong marks for even crisping. The most common complaint, and it's a real one, is the learning curve on steam timing — undercooking vegetables is a frequent early mistake, and the manual doesn't give enough guidance for improvising beyond the included recipes.

The Deal

At £169.99 against a £229.99 RRP, the £60 saving looks appealing, but the price history tells a more nuanced story: this model has previously dropped to £149.99 and averages £158.93 across 141 tracked data points, meaning today's price is actually above the historical average. It's a reasonable deal, not an exceptional one — worth buying if you need it now, but worth monitoring if you can wait for it to dip again.
