What Size Slow Cooker Do I Need?

General buying advice. Always check current specifications, prices and reviews with the retailer before you buy.

Slow cookers come in sizes from small 1.5 litre pots to big models of 6.5 litres or more. The right size depends on how many people you cook for and what you want to make. Here is a quick way to choose.

A rough guide by household

As a starting point, a small slow cooker of around 1.5 to 2.5 litres suits one or two people. About 3.5 litres suits two to four people. Around 5 to 6.5 litres is better for families or for cooking in batches. Makers' own serving advice varies, so check it for the model you like.

Think about what you cook

A whole chicken or a large joint of meat needs more room than a stew, so check that the food will fit with space around it. If you like to cook in bulk and freeze portions, a larger size is worth considering.

How full to fill it

Slow cookers usually work best when they are between about half and three-quarters full. A pot that is too empty can cook food too quickly, and one that is too full may not cook evenly. Check your manual for the maker's guidance.

Shape and lid

An oval pot suits joints and whole birds, while a round pot suits stews and soups. A clear lid makes it easy to check progress without lifting it.

Counter space and cleaning

Slow cookers can be bulky, so measure where it will go. A removable ceramic or non-stick pot is easier to clean, and many are dishwasher safe.
