Ninja Foodi MAX 15-in-1 SmartLid Multi-Cooker 7.5L (OL750UK)

The Foodi MAX is the pick for large families and batch cooking. It keeps the same single SmartLid convenience as the OL550 but stretches to 7.5L with 15 functions and a built-in Smart Cook System temperature probe, so it covers everything the 6L unit does plus extra steam-combi modes (Steam Meals, Steam Bread, Steam Roast) and the extra 1.5L of bowl for bigger single batches (Ninja rates it, like the 6L OL550, for up to 6 people). It is widely stocked at John Lewis, Currys and AO, with street prices frequently around £224 against Ninja's list price of £339.99 (as of September 2026). The reasons to size up are the 1.5L of extra capacity and the food probe the OL550 lacks; the reasons not to are the higher price and a noticeably larger footprint that makes it overkill for one to four people. It carries a 2-year guarantee.
