Instructions to Prepare Bobby Flay Grilled London Broil

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.

Pro Tips to Make Perfect Bobby Flay Grilled London Broil

Marinate overnight for the best flavor – The longer the steak marinates, the more tender and flavorful it becomes.
Let the steak come to room temperature – Take it out of the fridge 30 minutes before grilling for even cooking.
Use a meat thermometer – For perfect doneness: 125°F for rare, 135°F for medium-rare, 145°F for medium.
Let it rest before slicing – This helps redistribute the juices, preventing the steak from drying out.
Slice thinly against the grain – This shortens the meat fibers, making the steak more tender.
