  • 1 1/2 - 2 lbs London Broil
  • 1/4 cup Balsamic Vinegar
  • 1/4 cup Soy Sauce
  • 2 tbsp Worcestershire Sauce
  • 2 Garlic Cloves Minced
  • 1/2 tsp Dried Rosemary
  • 1/4 tsp Ground Black Pepper
  • 1/4 cup Olive Oil


  • In a small bowl, whisk together all ingredients (except the beef).
  • Lightly score the beef on both sides and place in a shallow dish or large ziploc bag. Add the marinade to the dish/bag and let sit in the fridge (covered if using a dish) for 1 to 24 hours.
  • Remove marinated meat from fridge and let sit at room temperature for 1 hour. After 30 minutes, turn the broiler on high and place your cast iron skillet under the broiler. Let it preheat for 30 minutes.
  • Quickly remove the skillet from the oven and carefully place the london broil in it and return to the oven for 5 - 7 minutes per side. Once cooked, let the london broil rest for 7 minutes before slicing to keep the juices in. I like to make an aluminum foil tent to keep it from getting cold. When ready, slice against the grain and enjoy!
