7 Best Slow Cookers (UK 2026 Review)

Best Slow Cookers for Easy Family Meals and Delicious Home Cooking

A slow cooker can turn a few simple ingredients into a hearty stew, tender casserole or comforting family dinner with very little effort. But choosing between different sizes, cooking settings and pot designs isn’t always straightforward, especially when you want something practical for everyday use.

Our review of the best slow cookers highlights the features worth considering, helping you find a reliable option for everything from midweek meals to weekend batch cooking.

Buying Guide & FAQ

How to Choose the Best Slow Cooker

Choose a Capacity That Suits Your Household

Slow cookers come in different sizes, so think about how many portions you normally prepare and whether you enjoy cooking extra meals for later.

  • 1.5–3 litres: Ideal for smaller portions, side dishes and meals for one or two people.

  • 3.5–5 litres: A versatile choice for couples and smaller families, with enough room for many everyday recipes.

  • 5.5–6.5 litres or larger: Useful for bigger households, batch cooking and preparing larger joints of meat.

Remember that the stated capacity isn’t always the amount you can safely cook. Slow cookers need some space above the ingredients, so check the recommended working capacity.

Decide Between Manual and Digital Controls

You don’t need complicated settings to make good meals, but some features can make cooking more convenient.

Manual slow cookers usually have low, high and keep-warm settings. They’re straightforward to operate and suitable for anyone who prefers simple controls.

Digital slow cookers may include programmable timers and automatic switching to keep-warm mode once cooking is finished. This can be particularly useful if you’re preparing dinner around a busy schedule. For most households, reliable temperature settings and a convenient keep-warm function matter more than having lots of cooking programmes.

How to Get Better Results From Your Slow Cooker

Slow cooking is simple, but a few small adjustments can make your meals noticeably better.

  • Brown meat for extra flavour: Searing beef, lamb or other meat before adding it to the pot creates a richer flavour, particularly in stews and casseroles.

  • Use less liquid: Slow cookers lose relatively little moisture, so you may need less stock or water than in a conventional oven or hob recipe.

  • Put firm vegetables near the bottom: Carrots, potatoes and other root vegetables generally take longer to soften and benefit from being closer to the heat.

  • Avoid lifting the lid repeatedly: Opening the lid releases heat and can extend cooking time. Check your food towards the end of the recommended cooking period.

  • Add delicate ingredients later: Soft vegetables, fresh herbs and dairy products can lose their texture or separate during extended cooking.

  • Thicken sauces near the end: If your casserole contains too much liquid, use an appropriate thickener or reduce the sauce separately rather than adding excessive flour at the beginning.

Cooking tip: For soups, stews and casseroles, prepare and refrigerate the ingredients the night before. You can then assemble the meal quickly the following day, following the manufacturer’s food safety instructions.

Can You Put Raw Meat Straight Into a Slow Cooker?

Yes. Slow cookers are designed to cook raw meat, provided you use a suitable recipe, follow the appliance instructions and cook the food thoroughly. You don’t have to brown meat beforehand, although doing so can improve flavour and appearance. Use properly thawed meat rather than placing large frozen pieces directly into the slow cooker. Check that poultry and other meats requiring thorough cooking reach a safe internal temperature before serving.

Are Slow Cookers Cheaper to Run Than Ovens?

Slow cookers can be economical for dishes that need several hours of gentle cooking, such as stews and casseroles. They generally use less power while operating than a conventional electric oven, although the total cost depends on the appliance, cooking duration and quantity of food. For larger batches, a slow cooker can be a convenient way to prepare several portions in one cooking session.

Can You Leave a Slow Cooker On While You’re Out?

Many slow cookers are designed for extended cooking periods, making them convenient for preparing meals while you’re busy. Always follow the manufacturer’s instructions regarding unattended operation. Place the appliance on a stable, heat-resistant surface with adequate clearance, and use a suitable wall socket. A programmable timer with automatic keep-warm mode can be helpful when your meal finishes before you’re ready to eat.
