No more sawing through tough, chewy London Broil that overstays its welcome. Our tested grilling method transforms this budget-friendly cut into juicy, melt-in-your-mouth perfection with a lick-the-plate smoky char.
Remove the London broil from the package and pat dry with paper towels.
Place the meat in a gallon size resealable ziplock bag.
Pour the marinade over the London broil and seal the bag, removing as much excess air as possible.
When the bag is sealed, use your hands to make sure both sides of the beef has been coated with the marinade.
Place in the fridge for 8 to 16 hours.
Preheat the Grill
When ready to cook, preheat a grill for a two-zone fire. See notes for charcoal grills.
Clean and oil the grill grates.
Grill the London Broil
Remove the marinated London broil from the bag and place the beef on the grill grates on the cool side of the grill.
Allow the meat to cook for 90 seconds, then, using long tongs, rotate the beef 90 degrees to create sear marks.
After another 90 seconds, flip the meat and continue to cook it, rotating as needed for even cooking, until the London Broil reaches 120 degrees F with an instant read thermometer.
If desired transfer the steak to the hot side of the grill and sear for another minute on both sides, adding more crust.
Rest and Serve
Remove the steak from the grill. Top it with compound butter and tent loosely with foil.
Allow the steak to rest for 10 minutes before slicing against the grain into thin strips to serve.
Notes
For a gas grill:
Preheat the grill by igniting all the burners and allowing the grill to preheat. If you want to smoke on a gas grill, add a smoker box over the hot side of the grill with wood chips now. We love Jack Daniels Wood Chips for steaks.
Clean and oil the grill grates.
Close the lid of the grill and allow it to preheat for 10 minutes.
Turn 2 of the 4 (or 2 of the 3 burners) off to create a 2 zone fire.
Add the steak to the cooler side of the grill and follow the directions for grilling.
For a charcoal grill:
Use a charcoal chimney to light charcoal. When it’s 70% ashed over, arrange the coals on one side of the grill to create a two-zone fire.
Place the grill grates over the coals and clean them.
Cover the grill with the lid and adjust the air vents to allow the grill to preheat to 375 - 400 degrees F.
When the grill is holding an even temperature, add the London boil to the hot side of the grill.
Allow the steak to cook for 90 seconds before rotating 90 degrees and grilling for another 90 seconds with the lid closed.
Flip the steak and place it on the cooler side of the grill, cover the lid and allow the steak to cook until it reaches medium-rare to medium doneness, using an instant read thermometer.
