How to Choose the Best Ninja Speedi
Match capacity to household size
If you routinely cook for larger groups, the Ninja Combi 12-in-1 SFP700UK handles meals for up to 8 people with its Combi Meals function. For medium households of up to 4 people, the standard 5.7L Ninja Speedi ON500UK or ON400UK prepares 4 chicken breasts alongside 200g of rice simultaneously. If kitchen space is very tight, the 3.8L Ninja CRISPi FN101UKGY offers a portable design with a glass cooking surface, though it holds less food than the 5.7L models.
Decide between 10-in-1 and 12-in-1 cooking modes
The Ninja Speedi 10-in-1 ON400UK covers essential programs like Speedi Meals, Steam Air Fry, and Slow Cook. Upgrading to the 12-in-1 Ninja Speedi ON500UK or the Amazon Exclusive Stone Gold ON500UKSTGD adds Prove and Reheat functions. Choose the 12-in-1 models if you regularly dough-prove bread or prefer dedicated reheating features over manual adjustments.
Factor in cleaning and accessory compatibility
Maintaining your cooker depends on the add-ons you select. Fitting the Aieve Air Fryer Splatter Screen onto the ON400UK prevents interior grease spots, but requires you to slightly increase cooking time and temperature. Alternatively, BYKITCHEN disposable paper liners keep sauces off the bottom of the 5.7L ceramic pot, while the Magla Square Air Fryer Rack Set uses stackable shelves and silicone feet to increase dehydrating space.
Buying Guide & FAQ
What is the best ninja speedi deal right now?

How much does a ninja speedi cost?
Across our top 10 picks, prices currently range from 10,97 £ to 280,00 £ on Amazon UK.
What is the main difference between the 10-in-1 and 12-in-1 Ninja Speedi?
The Ninja Speedi 12-in-1, available in Grey ON500UK or Stone Gold ON500UKSTGD, includes Prove and Reheat modes alongside the standard functions. The Ninja Speedi 10-in-1 ON400UK omits those two settings, but both share the 5.7L capacity and rapid steam-and-convection system.
How many portions can you make in a 5.7L Ninja Speedi?
The 5.7L Ninja Speedi models (ON400UK and ON500UK) prepare up to 4 portions at once. For instance, you can cook 4 chicken breasts, 500g of potatoes, and 200g of rice or 225g of pasta in one cycle.
Does using a splatter screen change how the Ninja Speedi cooks?
Yes. When using the 304 stainless steel Aieve Air Fryer Splatter Screen with the Ninja Speedi ON400UK, you need to increase both the cooking temperature and time slightly to compensate for the mesh barrier.

How does the Ninja CRISPi compare to the Ninja Speedi?
The Ninja CRISPi FN101UKGY is a smaller 3.8L portable air fryer featuring a PFAS-free glass container that lets you serve and store food directly in the bowl. The Ninja Speedi ranges use a 5.7L ceramic-coated metal pot designed for two-layer rapid steam and convection cooking.
