The Le Creuset Stoneware French Onion Soup Bowl is a beautiful way to serve the classic soup of caramelized onions swimming in a rich broth topped with a hearty slice of French bread and dripping with bubbling cheese. Le Creuset stoneware offers the ultimate in versatility and is fabulously durable. It can bake in an oven up to 500 degrees F, go in the microwave or under the broiler. It can also go from the freezer into a cold oven so stoneware, food, and oven heat up together. The enameled surface also makes them incredibly resistant to scratches, chipping, and staining.
