By the Simmer Pick editorial team · Updated 2026 · How we test & score

Large slow cookers (around 6L and up) are made for families and batch cooking - big stews, whole joints, and meals you can freeze for later. The extra capacity costs little more to run.

Frequently asked questions

What is the best large slow cooker?

A 6-8L model from Crock-Pot, Morphy Richards, Andrew James or a value brand handles family meals and batch cooking well. Remember usable capacity is a little less than the stated litres, so size up if you cook big joints or freeze portions.

Bottom line

Our top pick is the Morphy Richards Sear & Stew (our score 9.6/10) - A practical slow cooker (3.5L, manual dial, sear-in-pot) for easy, budget-friendly slow-cooked meals..
