To cook filet mignon on a charcoal grill, cook the meat uncovered using medium coals, turn once while grilling, wrap in foil after transferring to a plate, and serve after five minutes. When cooking a 1-inch cut, grill for 10 to 12 minutes to achieve a medium-rare steak and 12 to 15 minutes to achieve medium-done meat.
How to Grill Filet Mignon. 1  For a charcoal grill, place the meat on a grill rack directly over medium coals; grill uncovered. 2  For a gas grill, preheat the grill; reduce the heat to medium. 3  Place the filet on the grill rack over the heat. 4  Cover the grill. For cuts that are 1-1/2 inches thick, position the broiler rack so the steak will be 4 to 5 inches from the heat. 2  Preheat the broiler. 3  Place the beef filet mignon on the unheated rack of the broiler pan.
