Equipment

Ingredients

  • ¼ cup olive oil
  • 1 tablespoon soy sauce
  • 2 tablespoons balsamic vinegar
  • 1 tablespoon Worcestershire sauce
  • 3 large cloves garlic roughly chopped
  • ½ teaspoon dried thyme
  • 1 teaspoon kosher salt
  • ½ teaspoon black pepper
  • 1-2 ½ pounds London broil/top round

For the Garlic Herb Butter

  • ¼ cup unsalted butter room temperature
  • 1 small garlic clove minced
  • ½ teaspoon fresh lemon juice
  • ½ teaspoon lemon zest
  • 1 tablespoon fresh parsley finely chopped

Instructions

  • Combine oil, soy sauce, vinegar, Worcestershire, garlic, thyme, salt and pepper in a small bowl and whisk together.
  • Pour into gallon-sized zip bag and place meat into the bag. Close the bag, pressing all excess air out.
  • Set in refrigerator to marinate for at least 4 hours up to overnight.
  • Remove meat from refrigerator 30 minutes prior to cooking.
  • Set oven to broil. Place rack about 6-7 inches from broiler coil.
  • Remove London broil from bag and let excess marinade drip off. Place on a foil-lined sheet pan. Broil for about 3 minutes, then flip and continue cooking for additional 3-4 minutes, until a digital meat thermometer reads 135F for medium rare.
  • Place on cutting board and cover lightly with foil and allow to rest for 10 minutes. Cut against the grain into strips ¼ in thick.
  • For butter, combine all ingredients in a small bowl and stir together. Place on top of resting meat and serve.

Notes

  1. Marinate with Patience: Don't rush the marinating process, y'all. The longer your steak bathes in that flavorful marinade, the more tender and tasty it'll be. Aim for at least 4 hours, but overnight is even better for a flavor that really sings.
  2. Invest in a Meat Thermometer: Want to nail that perfect medium-rare without any guesswork? Get yourself a good kitchen thermometer. It's the secret weapon for ensuring your London Broil is cooked just right in the oven – not too raw, not too dry.
  3. Tenderize with a Mallet: For an extra tender London Broil, give it a good ol' pounding with a meat mallet before marinating. This little workout breaks down some of the tougher fibers, making each bite as tender as can be.
  4. Slice Against the Grain: When it's time to serve, always cut your steak against the grain. This shortens the fibers, making each piece more tender and easier to chew.
  5. Rest Before You Taste: After broiling, give your London Broil some well-deserved rest under a foil blanket for about 10 minutes. This allows the juices to redistribute, ensuring each slice is as juicy and flavorful as possible.
