The 7-bone roast (also known as the center-cut pot roast) or 7-bone steak is from the chuck section of the steer or heifer and it includes a cross cut of the shoulder blade. The bone is shaped like a "7", which gives these cuts their name. The steak differs from the 7-bone roast only in thickness. 7-bone steaks are cut 1/2- to 3/4-inch thick.
