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.
Warm sirloins will remain more tender and juicy during the grilling process than sirloins steaks that are put on the grill cold. Preheat the grill to medium-high or 400 degrees Fahrenheit.

When they are finished, the steaks should register 135 degrees Fahrenheit on an instant-read thermometer for medium-rare.
