Le Creuset is a French-Belgian maker of cookware. They are best known for producing enameled cast-iron cookware. The company first manufactured their products in the town of Fresnoy-le-Grand in France in 1925, which are similar in function to a Dutch oven but with T-shaped handles. The Le Creuset Dutch oven is on display in the Smithsonian Institution's National Museum of American History in Washington, D.C. as a part of the recreation of the chef Julia Child's kitchen. It has been widely reported to be her favorite cooking pot, though specialist sources hold that it was the Dutch oven of Le Creuset's less-remembered competitor Descoware that was her real favorite. The company also makes many other types of cookware and bakeware, from fondue-sets to tagines.

Heavy-duty cookware made of cast iron is valued for its heat retention, durability, ability to maintain high temperatures for longer time duration, and non-stick cooking when properly seasoned. Seasoning is also used to protect bare cast iron from rust. Types of cast-iron cookware include frying pans, dutch ovens, griddles, waffle irons, flattop grills, panini presses, crepe makers, deep fryers, tetsubin, woks, potjies, and karahi.
