‘Multi-cooker’ is one of the most abused terms in kitchen marketing. Some are pressure cookers with a slow-cook setting tacked on. Some are slow cookers that can sauté. The good ones genuinely replace three appliances. The bad ones do five things badly and clutter your worktop for £180.

Over six months we’ve tested eight multi-cookers in a UK kitchen, cooking the same beef stew, the same chicken curry, the same overnight porridge, and the same Sunday rice in each one. We measured come-up time on pressure, evaluated slow-cook consistency at the low setting, and tracked how easy each was to clean after a tomato-based stew (the cruel test that separates the good from the merely adequate). For the wider hot-cook category — air fryers and ovens — see our [best air fryers UK 2026] pillar.

If you’re choosing between Instant Pot and Ninja Foodi, that decision is covered in detail below. If you want one appliance to replace your slow cooker, your pressure cooker, your rice cooker, and possibly your air fryer too, the verdict box above is your shortcut.

Who tested this and how

All eight multi-cookers were tested by Ben in the same UK kitchen as our air fryer round-up — same 13A socket, same hob and oven for control comparisons, same kitchen scales and probe thermometer (Thermapen ONE) throughout. Testing ran from November 2025 to April 2026; total active testing time approximately 220 hours. Each unit was the primary cooking device for at least three weeks of daily use, and the four units in our top picks were used throughout the full six months.

Standardised tests across all eight units: (a) beef stew using a fixed 1.2kg recipe, weighed before and after for liquid loss, internal temperature checked with a Thermapen ONE; (b) chicken curry using the same Patak’s paste and fixed quantity of yogurt, sauce consistency rated against a reference photo; (c) overnight oats on slow-cook ‘low’, textural rating after 8 hours; (d) plain basmati rice on the rice setting, water-to-rice ratio per the manufacturer’s guidance, results rated for separation and stickiness. Cleaning was timed with a stopwatch after each tomato-stew test. Pressure-release noise was measured at 30cm with a decibel meter. UK pricing tracked across Amazon UK, Argos, John Lewis, and Lakeland throughout the testing period. None of the units were supplied free by manufacturers.

At a glance: the multi-cookers we tested

The comparison table below covers capacity, wattage, pressure rating, included functions, and footprint for each unit. Where a unit claims a function but performs it badly (most commonly: ‘air frying’ on units without a dedicated crisping lid), we note that in the function column rather than just listing it as a feature.

Multi-cookers are judged differently from single-purpose appliances. The question isn’t ‘is this a great pressure cooker’ or ‘is this a great slow cooker’ in isolation — it’s ‘does this genuinely replace the appliances it claims to, and does it cluster well with my actual cooking habits?’ Our top four answer yes; the bottom four either don’t, or don’t justify their price.

1. Ninja Foodi 14-in-1 SmartLid OL750UK — Best overall (£249)

After six months as the daily multi-cooker in a family-of-four kitchen, the OL750UK earns its place at the top by being the only unit we tested where the breadth of functions doesn’t compromise the depth of any single one. The SmartLid (one lid, two sealing modes — pressure and air-fry) is the genuine engineering breakthrough that lets it pressure-cook a stew and then crisp the top, all in the same pot, without lid-swapping. That single feature is what justifies its position above the Instant Pot Duo Crisp.

Pressure cooking is fast and consistent: our 1.2kg beef stew came up to pressure in 11 minutes and cooked to fork-tender in a further 35 — versus 3+ hours in a slow cooker or 90 minutes in a Dutch oven. Slow cooking on ‘low’ over 8 hours produced overnight oats with the right creamy texture and no burning at the base. The air-crisp function works well for finishing — chicken thighs that braised in liquid for 25 minutes came out genuinely crisp-skinned after 8 minutes of crisping with the lid down.

The 7.5L bowl-shape pot is large enough for a family stew but tall enough to make sautéing a hassle (you’re reaching down into the pot rather than across a pan). Cleaning is easy — non-stick has held up over 180+ cooks — and pressure release noise is moderate at 78dB. The footprint is large (35cm diameter, 33cm tall) and won’t fit under wall units. If we could only have one cooking appliance other than a kettle, this would be it.

2. Instant Pot Duo Crisp 9-in-1 — Best value (£169)

The Instant Pot Duo Crisp is what the Ninja Foodi was three years ago: a two-lid system (pressure lid and air-fry lid swapped manually) that does the same job for £80 less. The trade-off is genuine — swapping lids mid-recipe is the operational difference between the two — but for many households that’s a small price for £80 saved. Pressure performance is essentially identical to the Ninja in our beef stew test (12 minutes to come up, 38 minutes to fork-tender).

The air-fry lid attaches with a satisfying click and crisps adequately, though airflow is fractionally less aggressive than the dedicated air fryer in the Ninja. We measured 4°C lower top-of-pot temperatures during the crisp phase, which translated to two extra minutes for the same browning. For day-to-day cooking that’s invisible; for a weekly Sunday roast it’s a non-issue.

Build quality is the slight gap to the Ninja — the air-fry lid feels lighter, controls are slightly less premium, and the digital display is less readable in bright light. But six months of testing produced no actual reliability issues, and the Instant ecosystem (replacement seals, alternative lids, accessories) is the broadest of any brand. If your budget is hard-capped at £180 and you want pressure-cook plus air-fry, this is the buy.

3. Crock-Pot Lift & Serve 6L — Best slow cooker (£75)

Strictly speaking, the Crock-Pot isn’t a multi-cooker — it’s a dedicated slow cooker. We’ve included it because the slow-cook performance of every ‘multi-cooker’ in this test was meaningfully worse than the Crock-Pot’s, and for households who slow-cook two or more times a week it deserves space on the worktop in addition to (or instead of) a pricier multi-function unit.

The Lift & Serve gimmick — the inner pot has integrated handles that make it portable straight from cooker to dining table — is the kind of small detail that turns out to be useful three times a week. Stews go from kitchen to table without an additional serving dish; chillis and curries can be taken to a neighbour’s. The two heat settings (low/high) and timer are basic but reliable. Tomato-based stews that broke down to mushy in the Ninja held their texture better here, because slow cookers cook at lower stable temperatures than ‘slow cook’ modes on multi-function units.

If you only ever slow-cook, this is what to buy. If you slow-cook more than twice a week, this is what to buy in addition to a Ninja or Instant. The non-stick is genuine ceramic (not a coating), it’s dishwasher-safe, and at £75 it’s the cheapest competent option in the category. We’ve covered it in more depth in our slow-cooker round-up.

4. Tefal Cook4Me Touch CY912840 — Best one-pot for families (£200)

The Cook4Me’s distinctive feature is its built-in recipe library — 250+ guided recipes that walk you through ingredients, prep, and cooking step by step on the colour touchscreen. We were sceptical going in (most ‘guided cooking’ is marketing fluff) but in practice the recipes are genuinely well-developed and the time-saved on weeknight cooking is real. For families where one parent does most of the cooking and wants to reduce decision fatigue at 6pm, this is a meaningful upgrade.

As a pure pressure cooker the Cook4Me is fine rather than class-leading: come-up to pressure was a minute slower than the Ninja, and pressure-release noise was the loudest in our test at 84dB. Slow cooking is competent. There’s no air-fry function, which is the main reason it doesn’t take the overall top spot. The 6L capacity is right for a family of four. Cleaning is straightforward — bowl is dishwasher-safe.

The Cook4Me is the multi-cooker we’d recommend to time-poor parents who’d rather have decisions made for them than tweak temperature dials. If you’re a confident cook who’ll mostly write your own recipes, the Ninja or Instant offer better value for the same money.

5. Sage Fast Slow Pro BPR700 — Premium pressure + slow (£199)

Sage’s pressure-cooker-meets-slow-cooker is the build-quality leader in this round-up. Brushed stainless construction, the most precise pressure regulation we measured (within 0.05 bar of target throughout cooking), and the only unit with an automatic steam-release lever you can operate one-handed. As a pressure cooker and slow cooker combined, it’s excellent. As a multi-cooker, the lack of air-fry capability holds it back from a top-three slot.

The 6L capacity is family-suitable; pressure come-up was 9 minutes (the fastest in our test); and the 11 pressure presets are well-calibrated for British staples (stews, curries, beans, rice). Slow-cook performance is closer to the dedicated Crock-Pot than to other multi-cookers — temperature stability on ‘low’ was the best of the multi-function units. Pressure-release noise is the quietest in the test at 71dB.

If you have £200 and you don’t want air-frying capability, the Sage is genuinely the best buy — better-built and better-regulated than the Instant Pot Duo Crisp. If you do want air-frying as well, the Instant Pot Duo Crisp is the smarter spend. Long-term reliability has been excellent.

6. Russell Hobbs Express Chef Digital Multi Cooker (£90)

The budget option that does most of the basics adequately. Pressure cooking works (slower come-up than the premium units, but the end result is the same); slow cooking is competent; and the rice setting is well-calibrated for basmati. At £90 it’s the cheapest unit in our test that we’d actually recommend, and it’s the right buy for someone exploring multi-cookers for the first time before committing to a £200+ unit.

Compromises are honest: build quality is plasticky, the digital display is small, and the inner pot’s non-stick coating shows wear faster than premium units (visible scuffs after eight weeks of daily use). There’s no air-fry, no sauté setting worth using, and the recipe book is generic. But for £90 it does what it says and nothing it doesn’t, which is more than we can say for several pricier rivals. We’d expect three to five years of use rather than ten.

7. Morphy Richards Sear and Stew (£40)

A 6.5L slow cooker with a sear function on the removable inner pot — included here because at £40 it’s the budget-conscious household’s question: ‘do I really need a £200 multi-cooker?’ For pure slow-cook work it does a fine job, and the sear function (you sauté on the hob using the inner ceramic pot, then transfer to the slow-cooker base) is genuinely useful for stews where browning matters.

It’s not a pressure cooker, doesn’t air fry, and doesn’t pretend to. Compared with the Crock-Pot Lift & Serve at £75, the Morphy Richards is £35 cheaper but feels it — controls are more basic and the lid feels less robust. If you only need slow-cooking and you’re hard-budgeted, this is the unit. The Crock-Pot is the £35 upgrade that’s worth paying.

8. Tefal Multicook Advanced (£140)

Disappointing. Tefal’s other multi-cooker (not the Cook4Me Touch) tries to be everything — pressure, slow, rice, yoghurt, steam, sauté — and the result is a unit that does no single thing as well as a dedicated competitor at the same or lower price. Pressure come-up was the slowest in the test (16 minutes); slow-cook performance ran hotter than ‘low’ implies, drying out overnight oats; rice was middling. The 7L capacity is generous, but capacity isn’t the problem.

At £140 the Tefal Multicook Advanced sits awkwardly between the £90 Russell Hobbs (does the basics for less) and the £169 Instant Pot Duo Crisp (does more, better, for £29 more). We’d recommend either of those over this. Returned to retailer at the four-week mark — the only unit in this test that earned a ‘do not buy’ verdict.

Our testing methodology, in detail

Every multi-cooker was tested against the same standardised set of cooks, in the same kitchen, on the same 13A socket, with the same probe thermometer for verification. We use the same procedure across our cluster guides — slow cookers, pressure cookers, rice cookers — so scores are directly comparable.

Standardised tests: (1) 1.2kg diced beef chuck stew with stock, onions, and root veg — pressure-cooked or slow-cooked per the manufacturer’s recommended setting, weighed before and after for liquid loss, internal temperature 96°C target; (2) chicken thigh curry using a fixed quantity of Patak’s paste and yogurt, sauce consistency photographed against reference; (3) overnight steel-cut oats on ‘low’ for 8 hours, textural rating; (4) basmati rice cooked to manufacturer water ratio, evaluated for separation, stickiness, and burnt-base. Each test repeated three times across the testing window and averaged.

Scoring is out of ten across five weighted categories: cooking quality across all functions (35%), value-for-money (20%), build and long-term durability (15%), ease of cleaning (15%), and noise/footprint/usability (15%). Pressure-release noise was specifically measured at 30cm with a calibrated decibel meter; pressure regulation was monitored with a digital pressure gauge across two cooks per unit. Pricing tracked weekly across major UK retailers throughout the test window.

FAQ

Pressure cooker, slow cooker, or multi-cooker — which should I buy?

If you cook stews and roasts at weekends and want the meal-by-evening guarantee, a slow cooker is the cheapest, simplest answer (£40-£80). If you cook from scratch on weeknights and want stews ready in 45 minutes rather than 4 hours, a pressure cooker or pressure-capable multi-cooker is the better choice. If you do both regularly and have the worktop space, a multi-cooker like the Ninja Foodi or Instant Pot Duo Crisp is the right buy.

Are multi-cookers safe to leave on while you’re out?

Slow-cook mode: yes, that’s the entire design intent — they’re built for 8+ hours of unattended use. Pressure-cook mode: yes once the pressure has stabilised; modern units have multiple safety interlocks. We’d recommend not running pressure cooking the moment you walk out the door, but a 30-minute pressure cycle running while you collect kids from school is a normal use case. Always read your specific unit’s manual for the manufacturer’s stance.

Why does my multi-cooker say ‘burn’ or stop pressure cooking?

Almost always thickener at the base — flour, tomato paste, or starchy ingredients touching the bottom of the pot scorch, the unit detects the temperature spike, and aborts pressure mode. Solution: deglaze thoroughly after sautéing, layer thickeners on top of liquids rather than mixing them in, and never let tomato paste sit on the base. The Ninja Foodi is the most forgiving in our test; the Instant Pot is more sensitive.

How big a multi-cooker do I need?

For a single person or couple, 5L is plenty. For a family of four, 6-7L is the sweet spot. Above 8L you start seeing diminishing returns — the unit becomes too tall to sauté in comfortably, takes longer to come up to pressure, and uses more energy on small batches. The Ninja Foodi 7.5L was the right size for a family in our test; the 5L Instant Pot Duo Crisp Mini would be the better buy for one or two people.

Can multi-cookers genuinely replace an oven?

For braises, stews, curries, soups, rice, and steamed vegetables — yes, completely. For roasted whole chickens, baked goods, and proper cake — no. The crisp-lid units (Ninja Foodi, Instant Pot Duo Crisp) handle a small whole chicken adequately, but you won’t bake a sourdough or roast a Sunday joint in one. They’re additive to an oven, not a full replacement, despite marketing claims.

How long will a multi-cooker last?

Premium units (Sage, Ninja Foodi, Instant Pot Duo Crisp) regularly last 8-10 years with normal use. Budget units (£90 and below) last 3-5 years before non-stick degrades or the digital display fails. The single most replaceable component is the silicone sealing ring; budget for replacing this every 12-18 months on a unit you cook in daily.

The final word

If you take one thing from 220 hours of testing, it’s that the multi-cooker market has consolidated into two genuinely excellent options at the top — the Ninja Foodi 14-in-1 and the Instant Pot Duo Crisp — with the gap between them largely a question of whether you’d rather pay £80 more or swap a lid manually. For families who slow-cook regularly, add a £75 Crock-Pot Lift & Serve as the dedicated tool. For time-poor cooks who want decisions made for them, the Tefal Cook4Me Touch is unique. Everything else in this round-up is either a step down in capability or a step up in price without proportionate gain.

Whichever you choose, learn the burn-warning fix early (deglaze, layer thickeners), buy a spare silicone sealing ring at the same time as the unit, and don’t expect any multi-cooker to fully replace an oven. We’ll keep this guide updated quarterly with new arrivals and price changes.
