A good oven recipe for London broil is balsamic glazed London broil from Paula Deen. This recipe uses balsamic vinegar, brown sugar, garlic and a bay leaf to create the glaze for the meat.
Make a balsamic glazed London broil by seasoning 1 3-pound London broil cut of beef with salt and pepper to taste and placing it on a baking sheet. Mix 1/3 cup of balsamic vinegar, 1 tablespoon of brown sugar, 1 smashed garlic clove and 1 bay leaf in a skillet, and simmer on low until the mixture thickens. Remove the bay leaf and pour the glaze over the meat. Broil the meat in the oven just 4 inches from the heat for four minutes before turning it over for another four minutes. Allow the meat to rest for five minutes before carving it.
In order to make sweet and spicy London broil, whisk 3 tablespoons of extra-virgin olive oil with 2 tablespoons of sweet paprika, 2 tablespoons of light brown sugar, 1 tablespoon of kosher salt, 2 teaspoons of chili powder and the zest from 1 lime. Rub the mixture on both sides of 1 flank steak, and place it in a baking pan. Broil the steak for six minutes on each sides. Remove it from the oven and cover it with foil for 10 minutes before serving.
