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 around £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 around £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.

Our process

How we choose our picks

We don’t lab-test products ourselves. Instead we synthesise the strongest independent evidence — current Amazon UK listings, verified-buyer feedback, published specs and UK pricing — into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.

  • Current UK availability

    We only shortlist products actively listed and in stock on Amazon UK, checked against live catalogue data — not last year’s models.

  • Publicly visible buyer feedback

    We look at how each product is received by UK shoppers — its overall rating standing and the praise or complaints that recur in public reviews — rather than relying on a single reviewer’s opinion.

  • Published specs & value

    We compare manufacturer specifications, typical UK price bands, warranty and running costs so each pick is right for a real budget and use-case.

  • UK-specific fit

    We factor in UK voltage, plug/fitting standards, CE/UKCA marking and Consumer Rights Act cover — details that generic global lists miss.

Buying Guide

  • 1Decide if you need air frying. The Ninja Foodi's built-in air fryer function is its biggest differentiator. If you do not already own a separate air fryer, the Ninja effectively replaces two appliances. If you already have a standalone air fryer, the Instant Pot Duo's lower price and smaller footprint make more sense.
  • 2Measure your worktop space. The Ninja Foodi is substantially larger and heavier than the Instant Pot Duo — it needs 40 cm x 35 cm of clear worktop space plus clearance for its hinged lid. The Instant Pot Duo fits in roughly 33 cm x 30 cm. In smaller UK kitchens, this difference matters significantly.
  • 3Consider what you actually cook. If you mostly make soups, stews, curries, and rice — the core of UK family cooking — the Instant Pot Duo handles these perfectly and costs less. If you want to pressure cook and then crisp (roast chicken, ribs, baked potatoes), the Ninja Foodi's dual-lid system is worth the premium.
  • 4Check the capacity against your household size. The Ninja Foodi OP350UK (6L) and Instant Pot Duo (5.7L) suit 4-6 person households. Both brands offer smaller and larger variants. For couples or small families, the Instant Pot Duo Mini (3L) is a space-saving option with no Ninja equivalent.
  • 5Factor in cleaning and maintenance. The Ninja Foodi has more components to clean — the crisping lid, pressure lid, and cooking pot. The Instant Pot Duo has fewer parts and its stainless steel inner pot is dishwasher safe. Both brands sell replacement sealing rings and accessories on Amazon UK.

Editor's Note

For UK families who want the maximum number of cooking functions in one appliance, the Ninja Foodi is the stronger buy. The pressure cook plus air fry combination is genuinely useful — you can make a pulled pork in 45 minutes under pressure and then crisp the top in 5 minutes, all in one pot. No Instant Pot model replicates this workflow. However, the Instant Pot Duo remains the better pure pressure cooker and slow cooker for everyday UK cooking. Its recipe ecosystem is vastly larger (thousands of UK-adapted Instant Pot recipes exist online), it is simpler to use, and it costs around £50-100 less. If your cooking style centres on batch-cooking curries, soups, and stews — which describes most UK multi-cooker usage — the Instant Pot Duo is all you need. Both are reliable, well-supported products with strong UK customer service.

Our Take

If you don't already own an air fryer, the Ninja Foodi MAX is the smarter single purchase — it replaces two appliances and its TenderCrisp function is genuinely unique. But for the majority of UK households whose multi-cooker use centres on curries, soups, and slow-cooked stews, the Instant Pot Duo at around £89–130 does everything needed at roughly half the price and fits into the tightest British kitchen worktops.

Questions & answers

Frequently asked questions

Is Ninja Foodi better than Instant Pot UK?
The Ninja Foodi is more versatile because it adds air frying and crisping to the standard pressure cooking functions. It is better if you want one appliance to replace both a pressure cooker and an air fryer. The Instant Pot Duo is better for pure pressure cooking, slow cooking, and everyday meals — it is simpler, cheaper, and takes up less worktop space. Neither is objectively better; it depends on what you cook.
Can you air fry in an Instant Pot?
The standard Instant Pot Duo cannot air fry. Instant Pot does sell an 'Air Fryer Lid' accessory (around £30-40) that adds basic air frying capability, but it does not match the Ninja Foodi's dedicated crisping lid performance. The Instant Pot Duo Crisp+ is a premium model with built-in air frying, but it costs nearly as much as the Ninja Foodi.
How much electricity does a multi-cooker use UK?
Multi-cookers are energy-efficient compared to conventional ovens. The Instant Pot Duo uses approximately 700-1,000 watts during active pressure cooking and less during keep-warm mode. The Ninja Foodi uses 1,400-1,760 watts when air frying. A typical pressure-cooked meal costs 10-20p in electricity at current UK tariffs (24p/kWh average), compared to 30-50p for an electric oven.
What size Ninja Foodi or Instant Pot should I buy?
For 1-2 people, the Instant Pot Duo Mini (3L) is ideal. For 3-4 people, the standard 5.7L Instant Pot Duo or 6L Ninja Foodi works well. For families of 5+ or batch cooking, both brands offer 7.5-8L models. Remember that pressure cookers should only be filled two-thirds full, so effective capacity is lower than the stated volume.
