With an almost infinite amount of uses, a good quality dutch oven is a mainstay in any home kitchen. With a thick cast iron bottom, they're fantastic for one pot meals - in searing, sautéing, boiling, braising, baking, frying, deep frying - you name the cooking method, and they can do it. They can be used on the hobs (gas, electric, induction), in the oven, or even over an open flame. 

This 5 Quart Cast Iron Dutch Oven has looped handles which make it easier to move this from stove to oven and oven to stove. 

Note: 5 quarts is approximately 4.7 litres.
