The wide, shallow shape of the Le Creuset Large Rectangular Roaster in Marseille Blue enameled cast iron exposes the maximum surface area of your food to the heat source, whether it be all around heat in the oven or under the broiler. It can also be used on the stovetop for frying. For best results, in cooking roast meats, poultry or poaching fish the dish should be filled almost to the brim, so the top browns and crisps quickly, leaving the food beneath moist. The dish is ideal for making pasta dishes such as lasagna and baking delicious pies and desserts such as fruit cake and gingerbread. Great for pastry, the cast iron spreads the heat evenly and well with no soggy middles to pies or tarts. Also excellent for marinating. The surface will not spoil or discolor. Le Creuset cast iron cookware is suitable for use on all heat sources including electric, gas, ceramic, halogen top and induction. All Le Creuset enameled cast iron cookware is coated with the highest quality vitreous enamel. This hygienic, impermeable enameled surface means Le Creuset can be used for marinating food prior to cooking or for food storage after cooking. Since 1925, the skilled French craftsmen at Le Creuset have perfected enameled cast iron cookware at their factory in Fresnoy Le Grand France. Each Dutch Oven shape is one of a kind, made from molten steel and cast in a unique mold, and then expertly enameled. No other procedure yields cookware that so evenly distributes heat, browns and caramelizes food to perfection, and creates a masterpiece at the table. Warranted for the lifetime of the original owner. Made in France.
