How to Buy: a Slow Cooker

RETAIL ADVICE TO HELP YOU BUY BETTER

What to look for, which features are worth paying for, and how to choose the right one.

A slow cooker is one of those kitchen appliances that can genuinely make life easier. From casseroles and curries to pulled pork and batch cooking, it does the hard work while you get on with your day. My favourite is putting it on in the morning and dinner being ready to go when you get home from work. 

But with so many models available, from basic £25 slow cookers to multifunctional machines costing hundreds, how do you know which one is worth buying?

Here’s what I’d look for.

1. Size Matters

Slow cookers are measured in litres (L) in the UK and quarts (qt) in the US. Bigger isn’t necessarily better.

  • 1.5–3L / 1.6–3.2 qt: Ideal for one or two people.
  • 3.5–4.7L / 3.7–5 qt: A good everyday size for smaller households.
  • 5–6.5L / 5.3–6.9 qt: Better for families, batch cooking or preparing meals for the freezer.
  • 7–8L / 7.4–8.5 qt: Ideal for larger families, entertaining or cooking in bulk.

Remember, advertised capacity isn’t always usable cooking capacity. Check the manufacturer’s recommended fill level.

2. Manual or Digital?

Basic slow cookers typically offer three settings: low, high and keep warm. For many people, that’s perfectly adequate. Digital models offer programmable timers, with some automatically switching to keep warm when cooking finishes. Worth paying more for? Yes, if you regularly want to set your cooking time and have the appliance manage the rest.

3. Look for a Sear Function

Some slow cookers have removable cooking pots that can be used directly on the hob (stovetop in the US). This allows you to brown meat or soften onions before slow cooking, developing flavour without needing an extra frying pan.

4. Think about Cleaning and Storage

Look for a removable, dishwasher-safe cooking pot.

  • Ceramic pots: Retain heat well but can be heavy.
  • Metal pots: Generally lighter, with some suitable for hob use.
  • Oval pots: Particularly useful for whole chickens and larger joints of meat (roasts in the US).

And don’t forget to check the appliance’s dimensions. Some of the larger multi-cookers take up considerable cupboard or worktop space.

Before you go…a little advice from the shop floor

Don’t pay for features you won’t use. If all you want is to put a casserole on in the morning and come home to dinner, a basic slow cooker will do the job beautifully.
