Cassoulet (French pronunciation: ​[ka.su.lɛ], from Occitan caçolet [kasuˈlet]) is a rich, slow-cooked casserole originating in the south of France, containing meat (typically pork sausages, goose, duck and sometimes mutton), pork skin (couennes) and white beans (haricots blancs).The dish is named after its traditional cooking vessel, the cassole, a deep, round, earthenware pot with slanting sides.The region once known as the province of Languedoc is the traditional homeland of cassoulet, especially the towns of Toulouse, Carcassonne, and Castelnaudary, the town which claims to be where the dish originated.
