How to Make Marinated Grilled London Broil

  1. Obtain 1.5 lbs of the freshest, leanest top sirloin steak you can find. Ensure it's deep red in color.
  2. Lightly score both sides of the steak with a sharp knife, creating shallow cuts to allow the marinade to penetrate.
  3. Place the sirloin in a deep rectangular dish.
  4. Season both sides generously with 1 teaspoon of salt and 1/2 teaspoon of freshly ground black pepper.
  5. Insert 4-6 cloves of garlic into the meat by making small slits.
  6. In a measuring cup, combine 1/4 cup red wine vinegar, 2 tablespoons A1 Steak Sauce, and 1/2 teaspoon Tabasco sauce.
  7. Add 1/2 cup of chopped Spanish onions to the marinade.
  8. Pour the marinade over the steak, ensuring it's coated evenly on both sides.
  9. Cover the dish with plastic wrap and refrigerate for at least 3 hours, or preferably overnight.
  10. Preheat your charcoal or gas grill to high heat for 20 minutes.
  11. Place the marinated steak on the hot grill. For even cooking, place a small weight (like a brick wrapped in foil) on top of the steak.
  12. Grill for 1 1/2 minutes per side over high heat to sear.
  13. Reduce the grill heat to medium-low. Turn the steak every minute, ensuring you achieve beautiful criss-cross char marks.
  14. Grill until the steak reaches your desired doneness. For medium-rare, the internal temperature should be around 130-135°F. Use a meat thermometer to check for accuracy.
  15. Do not overcook! The steak should be pink inside.
  16. Let the steak rest for 5-10 minutes before slicing against the grain and serving.
