In cooking, stewing means preparing meat cut into smaller pieces or cubes by simmering it in liquid, usually together with vegetables.

A stew may be either simmered in a pot on the stove top or cooked in a covered casserole in the oven. Stewing is suitable for the least tender cuts of meat that become tender and juicy with the slow moist heat method. Cuts having a certain amount of marbling and gelatinous connective tissue give moist, juicy stews, while lean meat may easily become dry (see cooking).

White stews, also known as blanquettes or fricassées, are made with lamb or veal that is blanched, or lightly seared without browning, and cooked in stock. Brown stews are made with pieces of red meat that are first seared or browned, before a browned mirepoix, sometimes browned flour, stock and wine are added.

Stews may be thickened by reduction, but are more often thickened with flour, either by coating pieces of meat with flour before searing, or by using a roux or beurre manié, a dough consisting of equal parts of butter and flour.
