The Le Creuset stockpot is styled and colored to match other pieces in the collection, but due to its size is made of steel with an enamel coating. If it were made of cast iron you'd never be able to lift it safely, especially with bubbling soup or stew inside! The lid fits tightly to keep all those delicious aromas and flavors inside. This 8 quart pot is wonderful for simmering chicken stock or marinara sauce, boiling pasta for spaghetti night and steaming bulky vegetables.
