Ninja Foodi vs Instant Pot Duo: Which Multi-Cooker Wins for UK Kitchens?
Updated 2026-06-20
The Ninja Foodi and Instant Pot Duo are the two most popular multi-cookers in the UK, and they take fundamentally different approaches to all-in-one cooking. The Ninja Foodi combines pressure cooking with air frying — its crisping lid lets you pressure cook a chicken and then air fry the skin to golden perfection without transferring to another appliance. The Instant Pot Duo is the original multi-cooker that built the category, offering pressure cooking, slow cooking, rice cooking, steaming, and sauteing in a proven, reliable package. Both are staples on Amazon UK's bestseller lists and regularly feature in Black Friday deals at Currys, Argos, and John Lewis. UK buyers need to consider worktop space (the Ninja is significantly larger), cooking versatility (the Ninja does more), and budget (the Instant Pot costs less). This comparison covers every practical difference to help you choose the right multi-cooker for your kitchen and cooking style.

Pros & Cons
Ninja Foodi MAX Multi-Cooker OP350UK
Pros
- Built-in air fryer crisping lid replaces a standalone air fryer — saves buying a second appliance
- 9 cooking functions including dehydrate and bake, covering virtually every cooking method
- TenderCrisp technology lets you pressure cook then air fry in the same pot — unique to Ninja
- Large 7.5L capacity suits families of 4-6 for batch cooking
Cons
- Significantly larger and heavier than Instant Pot — dominates worktop space in smaller UK kitchens
- More expensive at £179-230, roughly double the price of a basic Instant Pot Duo
- Non-stick inner pot is not dishwasher safe and the coating can degrade over 2-3 years
Instant Pot Duo 7-in-1
Pros
- Stainless steel inner pot is durable, dishwasher safe, and will not degrade over time
- Compact footprint fits easily on standard UK kitchen worktops, even in smaller kitchens
- Massive online recipe community — thousands of UK-adapted Instant Pot recipes available free
- Significantly cheaper at £89-130 — strong value for the core pressure cooking functions
Cons
- No built-in air fryer or crisping function — requires a separate appliance or optional lid
- Fewer cooking functions (7 vs Ninja's 9) — no dehydrate, bake, or roast modes
- Smaller 5.7L capacity may not suit larger families or serious batch cooking
Our Verdict
The Ninja Foodi MAX wins for UK buyers who want maximum versatility from one appliance — its pressure cook plus air fry combination is unique and genuinely useful for families who would otherwise need both a multi-cooker and an air fryer. The Instant Pot Duo wins on value, simplicity, and practicality for everyday UK cooking. At roughly half the price, with a smaller footprint and a stainless steel pot that will last for years, it handles the recipes most UK families actually cook — curries, stews, soups, rice, and slow-cooked meals. If worktop space or budget is a constraint, the Instant Pot Duo is the smarter purchase.
