Beef Sirloin Steak

Beef sirloin is one of the two major subprimals of the beef loin primal cut, which runs from the 13th rib to the end of the hip bone. Butchers separate the sirloin into the top butt and the bottom butt; lean but flavorful top sirloin steaks are an affordable option for the grill while a tri-tip cut from the bottom makes a good choice for roasting.
