Our verdict · The do-everything default: one SmartLid pressure-cooks and air-crisps, so most UK families need nothing else on the worktop.
Buy it if
You want one appliance to replace a pressure cooker, slow cooker and air fryer for weeknight family dinners.

You already own an air fryer and only want an affordable pressure cooker, or if worktop space is tight.

The 11-in-1 Foodi is the do-everything default for a UK household. Its single SmartLid pressure-cooks AND air-fries or crisps without swapping or storing a second lid, covering 11 functions - pressure cook, slow cook, air fry, grill, bake, dehydrate, sear/saute, steam, yoghurt, steam air fry and steam bake - in a 6L body that feeds up to six. Expert Reviews names it their 'best all-rounder', crediting the one-lid design that removes mode-switching, while TechRadar frames the crisping lid as the decisive edge the Instant Pot lacks. The trade-off versus the budget pick is size and price: it is tall and bulky, and costs around £130 more than the Instant Pot for functions a casual cook may not use. It carries a 2-year guarantee.
