6 Steps for Cooking London Broil on the Grill

If you’re tired of fatty, bland steaks, why not try something different with a flavorful London broil? London broil is a cut of lean, marinated meat from a beef round, flank, sirloin or shoulder. To cook London broil on the grill, you'll need a great marinade, a little time for TLC and a grill set to high heat. The results will be delicious.

London Broil Preparation


Marinate your meat. We encourage innovation, so be bold. A London broil marinade doesn’t have to be complex — sometimes just a splash of soy sauce, garlic, olive oil, salt and pepper is enough to make your mouth water.


Here’s where time makes the difference. Marinate at least three hours before grilling, or up to 24 hours before it’s prime time. The longer your cut sits in the marinade, the more time it has to absorb the flavor.


Preheat your grill to high heat. A London broil doesn’t need to cook for too long. Once your meat goes on the grill, it should only take between 5 and 15 minutes depending on how done you want it. For thicker cuts, you may cook for about three minutes per side, then a lower heat setting for under 30 minutes.


Use our 4-Pack Steak Thermometer Set to get your temperature right. Check your London broil often to achieve rare (135°F) or medium-rare (145°F).


When set to high heat, you’ll get a crispy outer layer that melts in your mouth when you bite into it.


When you reach your desired temperature, take your whole roast off the grill and let it sit covered for 10 minutes. Let the juices flow back into the broil before carving those succulent strips. Thinly cut slices work best. Remember to cut across the grain.
