The USDA recommends cooking ground meat to 160 degrees. However, if you prefer your meat at a different temperature like I do, here's a handy guide. Rare burgers, cook for four to five minutes total to 120-125 degrees F. Medium-rare burgers, cook for five to six minutes total to 130-135 degrees F. Medium burgers, cook for six to seven minutes total to 140-145 degrees F. Medium-well burgers, cook for seven to eight minutes total to 150-155 degrees F. Well-done burgers, cook for eight to nine minutes total to 160 degrees F. Keep in mind, this is just a guide. Cooking time can vary depending on the heat of the grill and thickness of the patty.
