How Long Do You Grill Hamburgers? The answer depends largely on the thickness of your patties. The best thickness for cooking is about 1/2 to 3/4 thick. Cook the patties for 10 to 16 minutes, until the hamburger patties reach an internal temperature of 155 degrees for 15 seconds at the thickest part of the patty. Don't rely on the color of the meat to judge doneness.
Place the burgers on the bottom cooking plate. The number of burgers your Foreman holds varies with the model and how large you make the patties; however, you must space each burger at least 1/4 inch apart for even cooking on all sides. Close the grill without smashing the burgers. The top of the grill sits on the burgers by its own weight, so just lay it on the burgers without pressing. Cook 1/2-inch-thick burgers 3 to 5 minutes for medium-rare; cook for 5 to 6 minutes for medium; cook for 6 to 8 minutes for well-done.
