Use tongs to turn the meat. A fork pierces the meat and you can lose delicious juices. Depending on the thickness of the steak, it will reach its desired degree of doneness in 10 to 25 minutes. For rare meat, steaks that are one inch thick will need a total of 10 minutes on the grill, including searing. Steaks that are between one and one-and-a-half inches thick will be rare in about 12 minutes. For medium-rare meat, increase the cooking times by five minutes.
