How Long Do You Grill A 1 Inch Thick London Broil?
Grilling a 1 inch thick London broil usually takes about 5-6 minutes per side for medium-rare doneness. However, cooking time may vary depending on the temperature of the grill and the desired level of doneness. It is advisable to use a meat thermometer to check the internal temperature and ensure that it reaches 145°F for medium-rare, 160°F for medium, and 170°F for well-done.
