Bobby Flay Grilled London Broil Recipe

Bobby Flay Grilled London Broil recipe

London Broil is a cooking method rather than a specific cut of meat, usually made with flank steak or top round that is marinated, grilled over high heat, and then sliced against the grain. Bobby Flay’s version elevates this dish with a bold marinade that enhances its natural beefy flavors while keeping it tender and juicy.

Ingredients

For the Marinade

  • Olive oil – ⅓ cup
  • Soy sauce – ¼ cup
  • Balsamic vinegar – 3 tablespoons
  • Worcestershire sauce – 2 tablespoons
  • Garlic (minced) – 4 cloves
  • Dijon mustard – 1 tablespoon
  • Brown sugar – 1 tablespoon
  • Fresh rosemary (chopped) – 1 tablespoon
  • Smoked paprika – 1 teaspoon
  • Crushed red pepper flakes – ½ teaspoon (optional, for heat)
  • Salt and black pepper – To taste

For the Steak

  • London Broil (flank steak or top round) – 2 pounds
  • Olive oil (for grilling) – 1 tablespoon
  • Fresh parsley (chopped, for garnish) – 2 tablespoons
  • Lemon wedges (for serving) – Optional

Instructions

  • Prepare the marinade – In a mixing bowl, whisk together olive oil, soy sauce, balsamic vinegar, Worcestershire sauce, garlic, Dijon mustard, brown sugar, rosemary, paprika, red pepper flakes, salt, and black pepper.
  • Marinate the steak – Place the steak in a ziplock bag or shallow dish, pour the marinade over it, and refrigerate for at least 4 hours or overnight for maximum flavor.
  • Preheat the grill – Heat a gas or charcoal grill to medium-high heat (450-500°F) and brush the grates with olive oil.
  • Grill the steak – Remove the steak from the marinade, letting excess drip off. Grill for 5-6 minutes per side for medium-rare or adjust to preferred doneness.
  • Rest before slicing – Transfer the steak to a cutting board, cover loosely with foil, and let it rest for 10 minutes to retain juices.
  • Slice against the grain – Cut the steak into thin slices at a diagonal angle to maximize tenderness.
  • Garnish and serve – Sprinkle with fresh parsley and serve with lemon wedges for extra brightness.
