Ingredients

For the London Broil Marinade

• 1/2 cup soy sauce
• 1/4 cup olive oil
• 3 tablespoons Worcestershire sauce
• 2 tablespoons balsamic vinegar
• 2 tablespoons fresh lemon juice
• 2 tablespoons brown sugar
• 4 garlic cloves, minced
• 1 teaspoon Dijon mustard
• 1 teaspoon black pepper
• 1 teaspoon smoked paprika
• 1 teaspoon onion powder
• 1 teaspoon dried rosemary
• 1/2 teaspoon red pepper flakes (optional)

For the Beef

• 2 1/2 to 3 pounds London broil steak
• 1 tablespoon olive oil for cooking
• Fresh parsley for garnish

Instructions

1. Prepare the Marinade: In a medium bowl, whisk together the soy sauce, olive oil, Worcestershire sauce, balsamic vinegar, lemon juice, brown sugar, garlic, Dijon mustard, black pepper, smoked paprika, onion powder, rosemary, and red pepper flakes. Mix thoroughly until the sugar dissolves completely.

2. Marinate the Steak: Place the London broil steak into a large resealable plastic bag or shallow dish. Pour the London Broil Marinade over the meat, making sure every side is evenly coated. Seal the bag or cover the dish tightly and refrigerate for at least 4 hours. For the best flavor and tenderness, marinate overnight.

3. Bring to Room Temperature: About 30 minutes before cooking, remove the steak from the refrigerator. Letting the meat sit at room temperature helps it cook more evenly and prevents a tough texture.

4. Preheat the Grill or Oven: If grilling, preheat your grill to medium-high heat. If broiling indoors, preheat the oven broiler and position the oven rack about 5 inches from the heat source.

5. Cook the Steak: Remove the steak from the marinade and allow excess marinade to drip off. Discard the used marinade. Lightly brush the steak with olive oil and place it on the grill or broiler pan. Cook for about 6-7 minutes per side for medium-rare, depending on thickness.

6. Check the Temperature: Use a meat thermometer for accurate results. Medium-rare is around 130-135°F, medium is 140-145°F, and medium-well is 150°F.

7. Rest the Meat: Transfer the steak to a cutting board and let it rest for at least 10 minutes before slicing. This allows the juices to redistribute throughout the meat.

8. Slice and Serve: Slice the steak thinly against the grain. This step is essential for achieving tender bites. Garnish with fresh parsley and serve immediately.

Frequently Asked Questions (FAQs)

What is London broil?

London broil is usually a lean cut of beef, commonly top round steak or flank steak, that benefits greatly from marinating and high-heat cooking methods.

How long should I marinate London broil?

For the best results, marinate the steak for at least 4 hours. Overnight marinating is ideal because it allows the flavors to fully penetrate the meat.

Can I freeze the steak in the marinade?

Yes. One of my favorite meal prep tricks is freezing the steak directly in the marinade. As it thaws, the meat continues to absorb flavor beautifully.

Can I cook London broil in a skillet?

Absolutely. A cast-iron skillet works wonderfully for this recipe. Sear the steak over high heat for a flavorful crust, then finish cooking to your desired temperature.

Why should I slice against the grain?

Slicing against the grain shortens the muscle fibers, making the steak easier to chew and much more tender.

Can I reuse the marinade?

No. Once the marinade has touched raw meat, it should be discarded. If you want extra sauce for serving, prepare a separate batch.

What is the best cooking method for London broil?

Grilling and broiling are both excellent methods because they cook the steak quickly over high heat while creating a flavorful crust.
