Description

This grilled London broil recipe, inspired by Bobby Flay, features a flavorful marinade with bold ingredients and a quick, high-heat grilling method for juicy, tender steak with a beautiful char. It’s perfect for backyard barbecues or a weeknight steak dinner with flair.


Ingredients

  • 2 lbs top round steak (London broil)

  • 1/4 cup olive oil

  • 3 tbsp balsamic vinegar

  • 2 tbsp soy sauce

  • 2 tbsp Worcestershire sauce

  • 2 tbsp Dijon mustard

  • 4 garlic cloves, minced

  • 1 tbsp brown sugar

  • 1 tsp smoked paprika

  • 1/2 tsp crushed red pepper flakes (optional)

  • Salt and black pepper, to taste

  • Fresh chopped parsley (for garnish)


Instructions

  1. Make the marinade: In a medium bowl, whisk together olive oil, balsamic vinegar, soy sauce, Worcestershire sauce, Dijon mustard, garlic, brown sugar, smoked paprika, and red pepper flakes.

  2. Marinate the steak: Place the London broil in a large resealable plastic bag or shallow dish. Pour the marinade over the steak, making sure it’s well coated. Seal and refrigerate for at least 4 hours, preferably overnight.

  3. Preheat the grill: Remove the steak from the marinade and let it come to room temperature while you preheat your grill to high heat (around 450°F to 500°F).

  4. Grill the steak: Place the steak on the hot grill and cook for about 4-6 minutes per side for medium-rare, or until it reaches your desired level of doneness.

  5. Rest the meat: Transfer the steak to a cutting board and let it rest for 5-10 minutes to lock in the juices.

  6. Slice and serve: Slice the steak thinly against the grain. Garnish with fresh parsley and serve.


Notes

  • Don’t skip resting the steak after grilling—it helps keep the meat juicy.

  • Great with grilled vegetables, mashed potatoes, or a crisp salad.

  • For extra tenderness, score the meat lightly before marinating.
