  • 1 (3 to 3 1/2 lb.) top round London Broil
  • 1/2 cup water
  • 1/2 cup olive oil
  • 1/4 cup ketchup
  • 1/3 cup red wine vinegar
  • 1/4 cup minced onion
  • 2 large cloves garlic, minced
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon salt
  • 1/2 teaspoon dry mustard
  • 1/4 teaspoon dried red pepper flakes

  5. Grill the meat according to desired doneness, about 25 minutes for rare.
  6. Place reserved marinade in a small saucepan and bring to a boil.

Tips & Substitutions

For optimal flavor, marinate the London Broil for at least 12 hours. If you don't have red wine vinegar, balsamic vinegar is a good substitute. For a spicier kick, increase the dried red pepper flakes. Always allow the meat to rest for a few minutes after grilling to retain its juices.

Serving Suggestions

Serve the sliced London Broil with the simmered marinade drizzled on top for extra flavor. It pairs well with grilled vegetables or a fresh salad. For a complete meal, consider serving with creamy mashed potatoes or the refreshing Grandma Kay'S Cran-Raspberry Gelatin Salad. Enjoy it with a glass of red wine for a delightful experience.

Storage & Reheating

Leftover barbecued London Broil can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm slices in a skillet over low heat or in the microwave with a splash of water to prevent drying out. Avoid reheating multiple times to maintain quality.
