Grilled London Broil

Background and History

Grilled London Broil is a flavorful and versatile dish that originated in North America, despite its name suggesting a British origin. Traditionally made with a tougher cut of beef, such as flank steak or top round, London Broil is marinated, grilled, and thinly sliced against the grain for optimal tenderness. While its exact origins are unclear, London Broil has become a popular choice for outdoor grilling enthusiasts and is often served as a delicious and budget-friendly meal for gatherings and family dinners.


1 London Broil steak (about 1.5-2 pounds)

For the Marinade:

  • 1/4 cup soy sauce
  • 2 tablespoons Worcestershire sauce
  • 2 tablespoons olive oil
  • 2 cloves garlic, minced
  • 1 teaspoon black pepper
  • 1 teaspoon dried herbs (such as thyme, rosemary, or oregano)
  • Salt to taste
  • Fresh herbs for garnish (optional)

Serves 4-6 people
Preparation Time 10 minutes
Marinating Time  2-4 hours
Cooking Time  10-15 minutes


Prepare the Marinade

In a bowl, combine the soy sauce, Worcestershire sauce, olive oil, minced garlic, black pepper, and dried herbs. Mix well to combine.

Marinate the Steak

Place the London Broil steak in a shallow dish or a resealable plastic bag. Pour the marinade over the steak, ensuring it is evenly coated. Cover the dish or seal the bag and refrigerate for 2-4 hours, allowing the flavors to infuse into the meat.

Preheat the Grill

Preheat your grill to medium-high heat. If using a charcoal grill, make sure the coals are hot and evenly distributed.

Grill the Steak

Remove the steak from the marinade and discard any excess marinade. Season the steak with salt to taste. Place the steak on the preheated grill and cook for 5-7 minutes on each side for medium-rare, or until the desired level of doneness is reached. Use a meat thermometer to ensure an internal temperature of 135°F (57°C) for medium-rare.

Rest and Slice

Once cooked to your liking, remove the steak from the grill and let it rest on a cutting board for 5-10 minutes. This allows the juices to redistribute, ensuring a juicy and tender steak. Slice the steak thinly against the grain for maximum tenderness.

Garnish and Serve

Optionally, garnish the sliced steak with fresh herbs before serving. Serve immediately with your favorite side dishes.
