Cooking a London broil can be a straightforward and delicious way to prepare a tender and flavorful steak. Here’s a step-by-step guide to help you achieve the perfect London broil.
Choosing the Right Cut of Meat
London broil is typically made from a lean cut of beef, such as top round or top sirloin steak. Opt for a steak that is at least 1½ to 2 inches thick to ensure it remains juicy and tender during cooking[1][2][4].
Preparing the Marinade (Optional)
While not mandatory, marinating the London broil can significantly enhance its flavor and tenderness. Here are a few marinade recipes you can consider:
Marinade Ingredients
Basic Marinade:
1/3 cup soy sauce
1/3 cup lemon juice
1/2 cup olive oil
1/4 cup Worcestershire sauce
1 tablespoon minced garlic
2 tablespoons Italian seasoning
1 teaspoon pepper
1/2 teaspoon salt
Pinch of red pepper flakes (optional)[2]
Alternative Marinade:
¼ cup balsamic vinegar
¼ cup tamari (or soy sauce)
2 tablespoons Worcestershire sauce
2 teaspoons brown sugar
3 cloves garlic (lightly crushed)
1 cup beef broth[1]
Detailed Marinade:
1/2 cup olive oil
1/3 cup soy sauce
1/4 cup Worcestershire sauce
1/4 cup lemon juice
1/2 teaspoon lemon zest
1 tablespoon minced garlic
1 tablespoon dried Italian seasoning
1/2 teaspoon crushed red pepper flakes (optional)
1 teaspoon black pepper
1/2 teaspoon kosher salt
1/2 teaspoon onion powder
1 teaspoon smoked paprika[4]
Marinating Process
Whisk together the marinade ingredients in a large bowl or a resealable bag.
Add the London broil to the marinade, ensuring it is completely covered.
Refrigerate for at least 2 hours or up to 24 hours. For optimal results, marinate overnight[2][4].
Cooking the London Broil
Broiling Method
Preheat your broiler to high heat.
Remove the steak from the marinade and place it in a baking dish or on a sheet pan coated with cooking spray.
Broil for 5-6 minutes on the first side and 3-4 minutes on the second side, or until the internal temperature reaches 135°F for medium rare and 145°F for medium to well done[2][4].
Oven Method
Preheat your oven to 420°F (220°C).
Heat olive oil in an oven-proof skillet until it shimmers.
Sear the London broil on one side, then flip and sear on the other side. You can add herbs like thyme or rosemary for extra flavor.
Place the skillet in the oven and bake until the desired internal temperature is reached. This will be about 10-12 minutes for medium-rare and 14-15 minutes for medium[5].
Reverse Sear Method
Preheat your oven to a moderate temperature (around 300°F or 150°C).
Season the London broil with salt, pepper, and any other desired seasonings.
Place the steak in the oven and cook until it reaches an internal temperature of about 120°F (49°C) for medium-rare.
Remove the steak from the oven and let it rest for a few minutes.
Heat a skillet with neutral oil over high heat and sear the steak for 2-3 minutes on each side to achieve a crispy crust[1].
Resting and Slicing
Regardless of the cooking method, it is crucial to let the London broil rest for 5-10 minutes before slicing. This allows the juices to redistribute, making the steak more tender and flavorful. Always slice the steak against the grain for the best results[2][4][5].
