Le Creuset Signature Enameled Cast-Iron 7-1/4-Quart Round French (Dutch) Oven

An investment piece, but one of the most versatile. These things are heavy, stout, and efficient. Goes from the stovetop to the oven to the grill to the refrigerator, and if you take care of it, will last for life. A round model in the 7-quart range will accomplish most takes like braises, stews and soups, deep frying, and searing.
