For medium rare on a 1 inch top sirloin boneless steak, total cooking time should be about 8 to 10 minutes. For a 2 inch boneless top sirloin total cooking time of about 18 minutes will give medium rare results. Ideally, you should be using a great instant-read meat thermometer.
To broil, preheat the broiling element, and place sirloin steak on a broiler pan 2 to 4 inches (5-10cm) from the heat source. Depending on the size, cook 8 to 10 minutes, turning once. Remove steak when it reaches desired degree of doneness. To grill, brush sirloin steak lightly with oil and place directly over heat source. Grill 6 to 8 minutes, depending on thickness of the steak.
