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.
For medium-rare, cook the steak until the internal temperature is 135 degrees, then remove and allow the top sirloin steak to rest for 5 minutes. Use a good pair of tongs to flip the steak about half way through the cooking time. Once it is done, let it rest on the plate for 5 minutes before you cut into it.This lets the juices redistribute and keeps them from running out all over your plate. Serve up that perfectly grilled top sirloin steak and enjoy! melt the butter in the microwave. After the butter is melted, I add minced garlic (I actually use a garlic press) Brush the butter mixture onto one side of the steak. Make sure you get lots of garlic on there since the wife is out anyway. Lay the top sirloin steak onto the grill, butter side down.
