The variety of sizes and shapes available for slow cookers is endless. From 1.5 to 8 quarts, and everything between. The extra small models are perfect for simple reheating, like dips for parties. The 2 1/2 to 3-quart slow cookers are ideal for large families or for cooking just for your family. For small quantities of soups/stews it is great. A lot of slow cooker recipes work well with 6-quart models. The 3 1/2 to 4 1/2 Liter crock pot can be used for large-sized recipes.
