A slow cooker is an electric cooking appliance used to slowly cook meals at relatively low temperatures, compared to frying, sauteing, baking, broiling or grilling. Slow-cooked dishes are usually simmered at these low temperatures for several hours, and are often left unattended during cooking. Stews and roasts are common dishes made in slow cookers.

The trademarked terms Crock-Pot or Slo-Cooker are often used generically when referring to slow cookers.
