  • 2 1/2 pounds top round roast (often also labled London Broil at the store - read more about it here)
  • 1/2 cup olive oil
  • 1/3 cup soy sauce
  • 1 tablespoon brown sugar packed
  • 1 tablespoon lemon juice
  • 2 tablespoons Worcestershire sauce
  • 2 cloves garlic minced
  • 1/4 teaspoon black pepper


  • Whisk together the olive oil, soy sauce, brown sugar, lemon juice, Worcestershire sauce, garlic, and black pepper in a mixing bowl. (Read here for other marinade ideas.)
  • Add the roast to a large bowl and pour the marinade over the London Broil. Toss to make sure all sides are well covered. Cover the bowl and refrigerate for 6 to 24 hours.
  • Preheat your oven to 450 degrees. Prepare a roasting pan with a wire rack.
  • Place the roast on the wire rack, discarding the rest of the marinade. Roast for 15 minutes at 450 degrees. Reduce the temperature of the oven to 350 degrees and continue roasting until the meat registers 125 degrees with an instant read thermometer, about 30 to 45 minutes.
  • Remove from the oven and let stand for 10 minutes before slicing. Cut in thin slices to serve.
