London broil is not a cut of beef, but instead a way to prepare it. London broil is usually made with a top round steak, but can also be done with flank steak or sirloin steak.

The secrets to a great London broil are a flavorful marinade and slicing thinly against the grain. Leftover London broil makes great cold roast beef sandwiches. It's also great served with some homemade brown gravy.

Ingredients

  • 1/4 cup balsamic vinegar

  • 2 tablespoons olive oil

  • 4 cloves garlic, crushed

  • 1 teaspoon dried rosemary

  • 2 pounds boneless top round "London Broil" steak (about 2-inches thick)

  • 1 tablespoon freshly ground black pepper

  • Salt, to taste

Glass Bakeware Warning

Do not use glass bakeware when broiling or when a recipe calls to add liquid to a hot pan, as glass may explode. Even if it states oven-safe or heat-resistant, tempered glass products can, and do, break occasionally.
