how long to grill a hamburger
Divide ground chuck into 4 patties, using your thumb to create a small well in the center of each patty. Liberally season the patties on both sides with kosher salt and fresh cracked pepper. Lightly butter the cut side of each bun, and add to the grill for 60 â 90 seconds, or until just toasted and browned. Add hamburger patties over direct heat and grill covered for 3 minutes on each side for medium rare plus. Remove from grill (or top with cheese to melt) and rest 3 â 4 minutes before serving.
