How to Grill London Broil: A Complete Guide

London broil is a budget-friendly, flavorful cut of beef that can be transformed into a tender, juicy masterpiece when grilled properly. While its reputation for being tough can intimidate some home cooks, the right techniques and a little preparation can make all the difference. In this guide, you’ll learn everything you need to know about grilling London broil to perfection, from selecting the best cut to slicing it for maximum tenderness.

Choosing the Right Cut

Despite its name, London broil isn’t a specific cut of meat but a method of preparation. It’s typically associated with tougher cuts like top round, flank steak, or skirt steak. When choosing a London broil for grilling, look for the following qualities:

1. Thickness: Aim for a cut that is at least 1 to 1.5 inches thick. Thicker cuts are less likely to dry out on the grill.
2. Marbling: While London broil isn’t known for heavy marbling, a slight amount of intramuscular fat enhances flavor and tenderness.
3. Freshness: Select meat with a deep red color and avoid cuts that appear grayish or dull.

Prepping the Meat

Proper preparation is crucial to unlocking the full potential of London broil. Since it’s a tougher cut, tenderizing and marinating are essential steps.

1. Tenderizing:
   • Use a meat mallet to gently pound the meat, breaking down tough fibers.
   • Alternatively, score the surface by making shallow diagonal cuts in a crisscross pattern. This helps the marinade penetrate deeper.
2. Marinating:
   • A good marinade balances acidity, oil, and seasoning. Acids like vinegar, lemon juice, or soy sauce help tenderize the meat, while oils keep it moist. Add fresh herbs, garlic, and spices for extra flavor.
   • Example marinade:
     • ¼ cup olive oil
     • ¼ cup soy sauce
     • 2 tablespoons balsamic vinegar
     • 2 minced garlic cloves
     • 1 teaspoon dried thyme
   • Place the meat in a resealable plastic bag or a shallow dish, ensuring it’s fully coated. Marinate in the refrigerator for at least 4–6 hours, or overnight for the best results.

Preparing the Grill

Grilling London broil requires a balance of high heat for searing and moderate heat for even cooking. Here’s how to prepare your grill:

1. Gas Grill:
   • Preheat the grill on high for 10–15 minutes.
   • Set up two zones: one for direct high heat and another for indirect, lower heat.
2. Charcoal Grill:
   • Light the charcoal and let it burn until it’s covered in white ash.
   • Arrange the coals to create a two-zone fire.
3. Oil the Grates:
   • Use a grill brush to clean the grates.
   • Lightly oil the grates with a paper towel dipped in vegetable oil to prevent sticking.

Grilling the London Broil

Now it’s time to cook! Follow these step-by-step instructions for perfectly grilled London broil:

1. Remove and Dry:
   • Take the meat out of the marinade and pat it dry with paper towels. This helps achieve a good sear.
2. Sear Over High Heat:
   • Place the meat on the hottest part of the grill.
   • Sear for 3–4 minutes on each side, creating a beautiful crust.
3. Move to Indirect Heat:
   • Transfer the meat to the cooler side of the grill.
   • Close the lid and cook until the internal temperature reaches your desired level:
     • Medium-rare: 130°F
     • Medium: 140°F
   • Use a meat thermometer for accuracy.
4. Avoid Overcooking:
   • London broil is best when cooked to medium-rare or medium. Overcooking can make it tough and chewy.

Resting and Slicing

1. Rest the Meat:
   • Remove the London broil from the grill and let it rest for 10 minutes. This allows the juices to redistribute, keeping the meat moist.
2. Slice Against the Grain:
   • To ensure tenderness, identify the direction of the muscle fibers and slice perpendicular to them.
   • Use a sharp knife to cut thin slices, which enhances the eating experience.

Serving Suggestions

London broil pairs beautifully with a variety of sides and sauces. Here are some ideas:

1. Side Dishes:
   • Roasted vegetables (asparagus, Brussels sprouts, or carrots).
   • Creamy mashed potatoes or garlic herb rice.
   • Fresh garden salad with a tangy vinaigrette.
2. Sauces:
   • Chimichurri: A vibrant blend of parsley, garlic, vinegar, and olive oil.
   • Garlic butter: A rich and savory option for drizzling.
   • Red wine reduction: Adds a touch of elegance and depth of flavor.

Troubleshooting Tips

• Overcooked Meat: If the London broil is overcooked, slice it thinly and serve with a flavorful sauce to compensate for dryness.
• Undercooked Meat: Return the slices to the grill briefly, or finish them in a hot skillet.
• Marinade Variations: Experiment with different marinades, such as teriyaki, barbecue, or Mediterranean-inspired blends.

Conclusion

Grilling London broil doesn’t have to be intimidating. By choosing the right cut, marinating it properly, and using the correct grilling techniques, you can transform this affordable beef option into a delicious, tender meal.
