Ingredients

The following ingredients have 6 Servings
  • 1 2-pound London Broil steak (1 ½-inch thick)
  • ¼ cup finely minced onion
  • 2 tablespoons minced fresh thyme
  • 2 tablespoons Dijon mustard
  • ¼ cup Worcestershire sauce
  • ¼ cup olive oil
  • Kosher or coarse salt and freshly ground black pepper (to taste)

Instruction

  • Using a sharp knife stab the steaks to create little incisions all over the meat, or use a bladed meat tenderizer. Combine the onion, thyme, mustard, Worcestershire sauce, olive oil, and salt and pepper in a large sturdy zipper top bag or large container.   Place the steak in the marinade and turn to coat well.  Cover and refrigerate for at least 4 hours, and up to 12.
  • Let the steak come to room temperature for at least 30 minutes before cooking.  Preheat the grill or heat a grill pan over high heat.  Grill the steak, covered, until the meat is well browned on the outside but medium rare on the inside, 4 to 5 minutes per side. Let the meat rest for 5 minutes before thinly slicing across the grain.
