Chuck steak is a cut of
beef and is part of the sub primal cut known as the chuck. The typical chuck steak is a rectangular cut, about 1" thick and containing parts of the shoulder bones, and is often known as a "
7-bone steak," as the shape of the shoulder bone in cross section resembles the numeral '7'. This cut is usually grilled or
broiled; a thicker version is sold as a "
7-bone roast" or "chuck roast" and is usually cooked with liquid as a
pot roast.
