The Mitchell Family Farms top sirloin steak is a cut of beef that comes from the top sirloin, which is located in the rear of the cow. It is a lean, sapid cut of beef that is perfect for grilling, pan-frying, or broiling. Top sirloin steaks are typically about 1-1.5 inches thick and can weigh up to 1 pound. They are best cooked to medium-rare or medium.
