Steams grains and crisps mains together for full meals in one pot
The ON500UK centres on a 5.7-litre square cooking pot paired with a raised Cook and Crisp Tray that lets steam below and convection heat above work together, which is why owners consistently highlight complete Speedi Meals with grains, vegetables and protein finishing at once. Construction pairs a stainless steel exterior with touch controls and a dishwasher-safe nonstick pot, lending a sturdy, wipe-clean feel suited to daily countertop use. In practice, verified owners describe intuitive operation across air fry, steam bake, sear, slow cook, prove and reheat, with particular praise for even browning, accurate temperatures and fast full-chicken roasts. The square format earns repeated mention for usable capacity for up to four portions without the dead space of round pots. Counterpoints are modest but real, with one owner noting awkward retrieval from the upper tray and others leaving a bulky 7kg-plus unit out permanently. Nonstick longevity remains the open question for heavy users.
- Simultaneous one-pot cooking with fluffy grains below and crispy protein above
- Wide 12-function versatility from steam air fry to slow cook, bake and dehydrate
- Large square 5.7L pot handles family-size joints and four-portion batches easily
- Simple touch operation and easy-clean dishwasher-safe pot praised by owners
- Bulky 7kg-plus footprint needs permanent counter space
- Retrieving food from the upper tray level can feel awkward in use
Steam-and-crisp one-pot dinners for four, fast
The Stone Gold Speedi centres on a 5.7-litre nonstick pot and Cook and Crisp Tray housed in a stainless-steel body with digital touch control. Verified ownership sentiment points to strong everyday utility, with an 86 percent five-star share across 446 ratings reflecting reliable time saving for one-pot dinners, rice dishes, roasts and proofed breads. The steam-plus-convection approach stands out for small households, allowing pasta or rice to cook below while chicken, vegetables or potatoes crisp above without switching appliances. Ergonomics are generally positive, with clear controls, compact footprint for its capacity and dishwasher-safe parts aiding maintenance. Trade-offs emerge in placement and finesse. The upward-opening lid demands vertical clearance, weight is substantial for frequent moving, and air frying and grilling reward conservative temperatures to avoid drying. Sauté performance is serviceable rather than hob-like. Overall sentiment frames it as a convenient, well-built weeknight workhorse rather than a full replacement for gas cooking.
- Complete one-pot meals with fluffy grains below and crisped mains above in a single cycle
- Wide 12-function versatility from air fry, grill and bake to slow cook, prove and dehydrate
- Easy maintenance praised by owners with nonstick dishwasher-safe pot and steam to loosen residue
- Compact footprint relative to 5.7L capacity, well suited for up to four portions
- Attractive Stone Gold stainless finish with clear touch controls
- Tall flip-up lid needs overhead clearance and 7.29kg weight limits frequent moving
- Air fry and grill can dry foods if set too high, while saute heat feels slower than a gas hob
Pressure cooks in minutes, crisps to golden – all under one smart sliding lid.
Market research and verified owner sentiment position this 11-in-1 SmartLid model as a true workhorse for busy family kitchens. The stainless and plastic body feels solid and well engineered, while the sliding SmartLid removes the faff of swapping separate pressure and crisp lids, automatically surfacing relevant modes. Daily utility is where it shines, with owners regularly moving from sear to pressure cook to air fry in the same non-stick pot for bolognese, stews, whole chicken, roast potatoes and yoghurt, often far faster than a conventional oven. Touch controls and presets are intuitive, and the removable pot, basket and rack simplify cleanup. Ergonomics are the tradeoff, as the tall, heavy footprint demands permanent worktop space and careful handling around the hot lid and rack. A slight learning curve for times and release methods is common. Overall satisfaction is very high for versatility, speed and consistent crisping according to long term owners.
- Excellent versatility across pressure, crisping, roasting and slow cooking in one pot
- Fast, even results for roasts, stews, rice and crispy air-fried sides
- SmartLid design simplifies switching modes without storing a second lid
- Sturdy build with non-stick dishwasher-safe parts for straightforward cleaning
- Large, heavy footprint needs dedicated permanent worktop space
- Reversible rack and lid area get very hot and take practice to handle safely
Creamy stir-free risotto plus slow cook, sear and steam in one compact pot
Specialist rather than all-rounder, this 3.7-litre Sage multi-cooker pairs a brushed stainless housing with ceramic-coated aluminium bowl, glass lid and integrated stirring paddle for risotto lovers. Controls are push-button automatic modes covering stir-free risotto, rice, sear, saute, steam, slow cook and keep warm, with steaming tray, ladle, spatula and measuring cup included. In everyday use, verified owners consistently praise creamy, even-textured risotto without constant stirring, plus capable slow cooking for stews, curries and biryani, reliable steaming for vegetables and fish, and handy quinoa and porridge. Operation is quiet, cleanup is easy when the coating is intact, and several long-term owners report near-weekly use over many years. Trade-offs centre on the bowl, rice can catch after searing or on keep warm, water ratios need tweaking, single-serve risotto takes dialling in, and coating durability draws mixed feedback. Compact capacity and fixed presets also limit batch cooking versus larger family machines.
- Excellent creamy risotto results without constant manual stirring
- Effective sear plus slow cook combination for flavourful one-pot meals
- Quiet automatic operation with straightforward push-button modes
- Versatile steaming, rice, quinoa and porridge performance
- Smart brushed steel design with serving-ready bowl and useful accessories
- Bowl coating can chip or allow catching, especially with keep warm use
- Rice cooking often needs ratio adjustment and can stick after searing
- Modest capacity and fixed presets limit large-batch flexibility
Big-batch slow cooking meets genuinely crispy air frying in one 6-litre pot
Market research and verified owner sentiment position this Tefal as a practical value alternative to premium dual-lid multicookers, with particular praise for cooking quality. Owners repeatedly highlight tender chicken and curries, crisp chips and wings, and successful slow-cooked chilli, casseroles and even roast dinners using saute then roast modes. The ceramic non-stick bowl with handles lifts out for easy washing, most accessories are dishwasher safe, and the bright touch panel is described as simple and quiet in daily use. The 6-litre capacity suits up to six servings, and multi-layer cooking adds real weeknight efficiency. Trade-offs reflect size and clarity rather than core performance. At over 9kg and nearly 38cm deep, it demands permanent counter space and full lid clearance, steam escapes sharply on opening, and listings around manual versus auto stirring plus a thin companion app have caused confusion. Isolated trim durability notes suggest careful handling over time for lasting satisfaction.
- Excellent slow-cook and air-fry results for curries, chilli, chips and wings
- Large 6-litre ceramic bowl easily serves family-size portions
- Bright touch controls are simple to learn and quiet in daily operation
- Removable non-stick bowl and dishwasher-safe parts simplify cleanup
- Bulky 9kg-plus footprint needs dedicated counter space and full lid clearance
- Steam release on lid opening runs very hot and requires care
- Companion app guidance is thin and variant listings around stirring cause confusion
Pressure-cook tender, air-crisp golden — nine functions in one 6L pot
Built around a brushed steel and black housing with 6-litre nonstick pot, Cook & Crisp basket and stainless rack, the OP350UK centres on TenderCrisp Technology with separate pressure and crisping lids controlled by touch panel plus dial. Market research and verified owner sentiment position it as a genuine multi-appliance replacement for households up to four, moving from sear to pressure to air crisp in one vessel for stews, chilli, whole chicken, roast potatoes, steamed vegetables, yoghurt and dehydrated snacks with faster heat-up and flavour retention. Owners consistently praise reliable browning with little oil, one-pot convenience, simple release and dishwasher-safe cleanup, alongside energy savings versus running a full oven and hob daily. Trade-offs are size and routine: the near 11kg unit with 43cm depth needs permanent counter space, separate lid storage and overhead clearance for venting, larger air-fry batches need shaking for even browning, fan noise is noticeable, and heavy marinades can splatter the crisping element.
- True 9-in-1 versatility with sear-to-pressure-to-crisp workflow in a single pot
- Large 6-litre capacity comfortably handles family meals and whole poultry
- Nonstick dishwasher-safe pot and basket earn consistent praise for easy release and cleanup
- Strong verified satisfaction for faster heat-up, locked-in flavour and lower energy use than oven and hob
- Large and heavy with two lids to store, needs dedicated counter space and overhead clearance for venting
- Larger air-fry loads benefit from shaking, fan noise is noticeable, and heavy marinades can splatter the crisping lid area
One space-saving lid goes from pressure cooking to golden air-fried crisp in the same pot.
Positioned as the all-in-one answer for small kitchens, this 1500W Duo Crisp centers on its Ultimate Lid concept that avoids storing a second bulky air-fryer lid. Verified owner sentiment shows the idea largely works in daily use, with many households reporting surprisingly crisp results on chicken, roast potatoes, fish fingers and chips, plus dependable pressure cooking for stews and long-cook staples. The large stainless-steel pot earns consistent praise for durability and easy cleaning compared with short-lived nonstick alternatives, while whisper-quiet one-touch steam release simplifies operation. Ergonomics are the trade-off, as the 10.1kg unit with a 38cm-plus footprint feels permanent on the counter and heavy to lift or store. Research also flags a polarizing ownership pattern behind the 4.0-star average, including concerns about the fixed lid gasket that cannot be removed for deep cleaning or replacement, sparse guidance documents, and isolated reports of lengthy preheating or steam-valve faults.
- Single-lid pressure-to-air-fry system saves storing second lid and second appliance
- Large 6.15-litre stainless-steel pot praised for durability and easy cleaning
- Air fry-led versatility delivers crisp chicken, roasties and everyday frozen foods plus slow, sous vide and saute options
- Whisper-quiet one-touch steam release with programmable touch controls and included accessories
- Large 10.1kg footprint feels heavy to move and demands dedicated counter space
- Fixed silicone lid gasket cannot be removed or replaced, raising odor retention and long-term maintenance concerns
- Mixed reliability feedback includes long preheating, sparse instructions and isolated steam-valve faults
Buyer Questions and Expert Answers
What is the best overall multi-cooker for most UK homes?
The Ninja Speedi ON500UK Grey stands out for most households because its Rapid Cooking System makes a complete meal — fluffy rice or pasta below, crispy chicken, fish or vegetables above — in a single cycle. With 12 functions from steam air fry to slow cook and bake, plus a large 5.7L square pot, it covers weeknights and weekends without pressure-cooking complexity.
What is the difference between Ninja Speedi and Ninja Foodi SmartLid?
Speedi focuses on speed and layering: steam plus air fry at the same time for one-pot Speedi Meals. Foodi SmartLid focuses on versatility with true pressure cooking plus air fry and steam-crisp via a sliding lid. Pick Speedi for fastest grain-plus-main dinners, pick SmartLid if you regularly cook dried beans, tough stewing beef, large joints or want pressure-tender results finished crisp.
What size multi-cooker do I need for a family of 4?
A 5.7L to 6L pot is the sweet spot for 3 to 5 people in the UK. The Speedi 5.7L square shape fits joints and four salmon fillets with grains well, while the 6L SmartLid with its separate crisp basket handles batch stews and roast-plus-sides. Measure width, depth and especially height for flip-up lids, and allow rear ventilation.
Do multi-cookers save energy versus an oven?
Yes for small to medium meals. A compact insulated pot with air fry, steam-crisp or pressure reaches temperature faster and cooks shorter than heating a full UK oven, especially for Speedi Meals, roast chicken pieces, rice and reheats. Savings shrink for very large batches or long slow cooks, where an oven or dedicated slow cooker can be comparable.
How do I keep the nonstick pot and lid lasting?
Let the pot cool slightly, soak or run a short steam cycle to loosen starch, then wash with soft sponge — most pots and trays are dishwasher-safe. Avoid metal utensils and harsh scourers, dry fully, wipe the lid underside and seal after steam or pressure use, and descale occasionally if you live in a hard-water area.
The Bottom Line
- 🏆 Top Overall Choice: Ninja Speedi 12-in-1 Multi-Cooker, Air Fryer and Slow Cooker, Grey ON500UK — best for fast, complete one-pot family meals
- 💰 Best Value: Ninja Speedi 12-in-1 Multi-Cooker, 5.7L Cooking Pot, Stone Gold ON500UKSTGD — same Rapid system with easy-clean care
- ⭐ Premium Pick: Ninja Foodi 11-in-1 6L SmartLid Multi-Cooker, Stainless Steel/Black OL550UK — best for pressure cooking plus crisping without lid swapping
For 2026 UK kitchens short on time but not on appetite, the Speedi approach wins for everyday ease, while true pressure still rules for batch cooking enthusiasts. All three winners demand permanent counter space and a little learning curve around crisping heat and hot trays, but reward you with fewer pots, faster dinners and consistent family-size results. Pick the system that matches how you actually cook — rapid layered meals or pressure-plus-crisp versatility — and you will use it daily.
