- From baking to oven-roasting, the Le Creuset Stoneware Heritage 2½ qt. Square Casserole is a functional all-in-one design that stands up to years of use with a durable finish and solid ceramic construction that's stronger than typical earthenware. This particular design features slightly higher side walls, making it ideal for small casseroles, layered baked pastas or even an ice cream cake. The Heritage collection brings back vintage designs from Le Creuset's past.
