Best slow cookers UK 2026: top rated picks tested by Mumsnet

Whether you need a low-effort tea on a busy weeknight or you're feeding a crowd at the weekend, the best slow cooker earns its cupboard space fast.

These are our recommended slow cookers for 2026 - chosen from Mumsnet forum favourites, expert reviews and hands-on testing, then shortlisted for performance, ease and value. We've tested five popular models in real home kitchens (including stews, curries and slow-roasted meats) to find the ones that are genuinely easy to use, easy to clean and worth the money. Some people use ‘Crock-Pot’ as shorthand for slow cookers - we’ve included Crock-Pot and non-Crock-Pot models.

Slow cookers are brilliant for hands-off, energy-efficient cooking - and they're not just for stew. Think creamy porridge, pulled pork, dhal, even a surprisingly decent risotto. If you're choosing between gadgets, our best air fryer guide is a good comparison point too.

And if you like the idea of one appliance doing several jobs (sauté, rice, steam), skip ahead to our best multi-cookers guide. Looking to kit out your whole kitchen? We also have guides to the best kettles and toasters, as recommended by Mumsnet editors.

How we chose and test the best slow cookers

To find the best slow cookers for different households and budgets, we started with what real parents rate. We analysed trusted recommendations from Mumsnet forum users, focusing on models people repeatedly praised for reliability, value and family-friendly cooking.

Next, we cross-checked our shortlist against verified customer reviews and feedback from food industry experts, prioritising slow cookers consistently praised for performance, durability and ease of use.

Finally, we did our own hands-on testing. Mumsnet’s home and kitchen editor Natasha Gregson, MNHQ tester Amelia Stamp and writer Roanna Day tested each shortlisted model in real home kitchens, cooking a range of dishes (including stews, curries and slow-roasted meat). We scored every slow cooker on: ease of use, ease of cleaning, cooking performance, features (like timers and keep-warm), capacity and value for money.

Only the models that performed well across the board made our final list - with links to full reviews under each pick.

Where to buy slow cookers (Argos, Amazon and more)

Slow cookers are widely available in the UK, but prices and stock can change quickly, especially on popular models. We’ve linked to trusted retailers like Argos, Currys and Amazon (plus others where relevant), so you can compare deals and delivery options without trawling around.

We always recommend checking the latest price and returns policy before you buy - and if you’re buying for a family, double-check the capacity and dimensions so it’ll actually fit your kitchen.

What are the benefits of slow cooking?

Slow cooking gives you tender, flavourful meals with minimal hands-on time – ideal for busy families and cheaper cuts of meat.

They're a handy kitchen appliance because they allow you to cook food at a low temperature over a long period of time. They are a great energy-efficient option for busy families who want to come home to a hot meal that's ready to serve up at the end of the day.

Mumsnet users love slow cooking for its time-saving qualities, but it also has some culinary pros too; the gentle heat combined with the long cooking process helps to tenderise tough and cheaper cuts of meat and enhance the flavours of staple dishes like beef stews and casseroles.

What to consider when buying a slow cooker

There are so many options on the market, it can be tricky deciding on the best slow cooker for your family. Here are a few things to consider:

• Cooking modes: Are you looking for a basic, manual slow cooker to prepare family favourites like chicken soup and chilli, or do you want to unleash your inner Masterchef with a multi-cooker that's kitted out with extras like a pressure cooker mode and a temperature probe? Think about your budget, too – multi-functional gadgets will be pricey, whereas you can pick up a slow cook-only model from as little as £20.

• Capacity: Slow cookers range from around 1.5L to 7L. Think about your household size, whether you batch cook, and how much cupboard/counter space you’ve got. (See our FAQ below on choosing the right size.)

• Features: A keep warm function is handy for busy families - it keeps your meal hot without the risk of overcooking it. On basic models, you'll have to manually switch to this setting, whereas more expensive slow cookers may have a timer that makes this change automatically when your meal is ready.

• Cooking pot: Some models have inner pots that can be used to sear meat on the hob before you start slow cooking, saving you extra washing up. Ceramic pots are not hob safe, however, so you will need to use a separate frying pan or saucepan if you want to brown meat or soften veggies before adding them to your slow cooker.

Slow cooker size guide (quick pick)

What size slow cooker do I need for a family of four?

For most families of four, 3.5L to 5L is the sweet spot. A 3.5L model is usually fine for a standard family dinner (curry, chilli, bolognese sauce) if you’re not relying on leftovers. If you batch cook, regularly cook for guests, or you’ve got big appetites (hello, teenagers), a 6L to 6.5L slow cooker is often more practical.

Slow cookers also work best when they’re not filled right to the brim. As a rough guide, aim for the pot to be around half to two-thirds full for steady cooking. Too full and it can take longer to come up to temperature; too empty and some dishes can dry out.

A quick way to picture it:

• 3.5L: everyday family meals, porridge, smaller joints

• 4.7L to 5L: flexible all-rounder with leftovers

• 6L to 6.5L: batch cooking, bigger joints, guests

If space is tight, check the footprint as well as the litres - bigger models can be properly chunky. And if you’ll use it weekly, features that make daily life easier (timer, keep-warm, easy-to-clean parts) matter as much as capacity.

Are slow cookers cheap to run?

Generally, yes. Slow cookers tend to be cheaper to run than an oven because they use a lower heat and are designed for long, steady cooking. Exact costs vary by wattage, tariff and how long you cook for.

Slow cooker tips for better results (and less washing up)

Here are five tips to help you get the most out of using your slow cooker:

1. Cut ingredients into similar sizes for even cooking. You can prep the night before and keep ingredients covered in the fridge; Heather Whinney (author of The Slow Cook Book) recommends a meal plan so “you have your ingredients at the ready for the pot the morning before supper.”

2. If you’ve got time, brown meat first for extra flavour (or choose a model with a hob-safe pot so you can sear in the same dish).

3. Layer wisely: slower-cooking ingredients at the bottom (closest to the heat), quicker-cooking ingredients on top.

4. Try not to lift the lid too often – each peek releases heat and can extend cooking time.

5. You’ll usually need less liquid than oven cooking because it doesn’t evaporate as much; Heather advises reducing liquid by around a third.

Can you leave a slow cooker on overnight or while you’re out?

Many people do use a slow cooker while they’re asleep or out, because it’s designed for long, low-temperature cooking. The sensible approach is the same as with any plug-in appliance: use a cooker in good condition, keep it on a flat, heatproof surface and leave space around it so heat can escape.

A few practical habits help it feel genuinely “set and forget”:

• Don’t keep lifting the lid (it drops the temperature and extends cooking time).

• Use the right amount of liquid - slow cookers don’t evaporate like ovens, so too much can leave meals watery.

• If your day is unpredictable, a keep-warm function is useful for avoiding overcooking if dinner gets delayed.

• If you prep ahead, keep ingredients chilled until cooking starts (especially meat and dairy).

If you’re ever unsure about a recipe starting temperature (for example, cooking from frozen), follow the recipe guidance carefully - most slow-cooker recipes assume defrosted ingredients.

Is a multi-cooker better than a slow cooker?

It depends what you want the appliance to do. A slow cooker is ideal if you want simple, low-effort cooking for stews, curries, soups and slow-cooked meats. A multi-cooker earns its keep if you want one gadget that can do more - often including sauté/browning, rice cooking, steaming, and sometimes pressure cooking.

The main trade-off: multi-cookers can be bulkier and pricier, but they solve a common slow-cooker niggle - needing a separate pan to brown meat or soften onions. If you like the idea of searing in the same pot (less washing up, better flavour), a multi-cooker or a slow cooker with a hob-safe pot can be a better fit.

Choose a slow cooker if you want a low effort, low fuss and reliable 'bunt it in' family dinner. Choose a multi-cooker if you want to brown or sauté in the same pot, have more weeknight flexibility or just one appliance to replace several.

Do you need a slow cooker with a timer (or will manual do)?

If you want “set it and forget it” convenience, a slow cooker with a timer is worth it. Digital models let you choose hours and minutes, and many will automatically switch to keep warm when the cooking time ends - handy if something derails dinner.

A manual slow cooker can still be brilliant value if you’re usually home to turn it down yourself, but you’ll need to remember to switch it to low/keep warm to avoid overcooking. If you’re buying for weekday use, look for a clear display, an easy-to-use timer and a reliable keep-warm setting.

Is a hob-safe sear pot worth it?

It can be - especially if you like deeper flavour but hate extra washing up. Browning meat (and softening onions/garlic) before slow cooking adds richness and stops some dishes tasting a bit… beige. The downside is that many slow cookers come with ceramic pots that aren’t hob-safe, so you end up using a separate frying pan first.

A model with a hob-safe sear pot (or a multi-cooker with a sauté function) lets you do the whole job in one pot, which is quicker, tastier and easier to clean.

If you regularly cook stews, chilli or pulled meat, it’s a genuinely useful upgrade - but if you mostly do simple “dump and go” recipes, you may not miss it.
