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.
Take note of what time you put them on the grill so you can time this exercise. After about 5 or 6 minutes (again, it's hard to say how long it will take to cook a hamburger on your grill, but you'll know after a few attempts), you should start seeing juices starting to collecting on the top of your burger.
