    • Flank Steak: Known for its distinct grain and robust flavor; it comes from the lower abdomen of the cow. It’s thinner than most cuts and requires marinating to become tender.
    • Top Round: This cut comes from the rear leg and is slightly thicker with a mild flavor. It’s more tender than flank but still benefits from marinating to maximize tenderness.

    Each cut is best cooked quickly over high heat to retain juiciness. Cook them between medium-rare (130°F) to medium (140°F) for optimal results. Slicing it against the grain enhances its tenderness, making it more enjoyable to eat.

    Preparing London Broil for Grilling

    Preparing your London broil properly ensures a flavorful and tender result. Focus on marinating and seasoning to enhance the meat’s natural flavors.

    Marinating Tips

    • Choose a Marinade: Select a marinade that includes acidic ingredients, such as vinegar, citrus juice, or wine. These components help tenderize the meat. For example, a combination of soy sauce, garlic, and olive oil works well.
    • Marinate Time: Allow the meat to marinate for at least 30 minutes, but ideally 4 to 12 hours. Longer marination enhances flavor and tenderness without overpowering the meat.
    • Refrigeration: Keep the London broil in the refrigerator while marinating. This prevents bacterial growth and maintains a safe temperature.
    • Dry Before Grilling: Remove the meat from the marinade and pat it dry with paper towels. This step prevents steaming and promotes a better sear on the grill.

    • Simple Salt and Pepper: A classic mix of salt and black pepper provides a clean flavor. Apply it generously before grilling.
    • Herb Blends: Mix herbs like rosemary, thyme, and oregano for an aromatic profile. Rub the herbs into the meat for increased flavor.
    • Spices for Heat: Add paprika, cayenne pepper, or chili powder for a bit of heat. A sprinkle enhances the smoky taste during grilling.
    • Garlic and Onion Powder: Use these powders for additional depth. Combine them with other spices for a robust seasoning blend.

    By following these preparation tips, you’ll set the stage for a delicious London broil on the grill.

    Cooking Times for London Broil on the Grill

    Cooking time plays a critical role in achieving the perfect London broil. Factors like thickness and desired doneness directly impact how long you grill the meat.

    Recommended Cooking Time Based on Thickness

    Cooking times largely depend on the thickness of your London broil. Typically, for every inch of thickness, follow these guidelines:

    • 1-inch thick: Grill for 4 to 5 minutes per side.
    • 1.5-inch thick: Grill for 5 to 6 minutes per side.
    • 2-inch thick: Grill for 6 to 7 minutes per side.

    Use a meat thermometer for accuracy, aiming for an internal temperature of 130°F for medium-rare. Adjust the time slightly if your cut varies in thickness.

    Desired Doneness and Its Impact on Time

    Desired doneness significantly affects cooking time. Here are the internal temperature ranges for different levels of doneness:

    Rest the meat for 5-10 minutes after grilling for optimal juiciness. This allows the juices to redistribute, enhancing flavor and tenderness.

    Tips for Grilling London Broil Perfectly

    Grilling London broil perfectly involves attention to detail and a few key techniques. Follow these tips for the best results.

    Preheating the Grill

    Preheat your grill to high heat, reaching about 500°F. This temperature creates a good sear, locking in juices and flavors. Allow the grill to heat for around 15 minutes, ensuring those grates are hot. For gas grills, ignite the burners on high. For charcoal grills, wait until the coals turn white-hot, indicating they’re ready.

    Using a Meat Thermometer

    Using a meat thermometer ensures accuracy in doneness. Insert the thermometer into the thickest part of the meat, avoiding bones and fat. Aim for an internal temperature of 130°F for medium-rare and 140°F for medium. Each grill varies in heat distribution, so always check the temperature instead of relying solely on time. This small step guarantees juicy, perfectly cooked London broil every time.

    Conclusion

    Grilling London broil can be a rewarding experience when you know the right techniques. By focusing on marinating and seasoning you’ll elevate the flavors and tenderness of the meat. Remember to keep an eye on the cooking times based on thickness and desired doneness.

    Don’t forget to let your meat rest after grilling. This simple step makes a world of difference in juiciness. With these tips in mind you’re well on your way to serving up a delicious London broil that’ll impress your family and friends. Happy grilling!

    What is the ideal cooking time for London broil?

    Cooking time varies by thickness. For a 1-inch thick piece, grill for about 4 to 5 minutes per side. Adjust the time for thicker cuts while checking for doneness.

    What is the recommended doneness and temperature for London broil?

    Aim for an internal temperature of 130°F for medium-rare and 140°F for medium. This ensures a juicy and tender result.

    Why should I slice London broil against the grain?

    Slicing against the grain helps break up the muscle fibers, resulting in a more tender eating experience. This technique maximizes the meat’s juiciness and makes it easier to chew.

    How can I achieve a good sear on London broil?

    Preheat your grill to high heat (around 500°F) for about 15 minutes. A well-heated grill ensures a good sear, locking in the juices for a flavorful London broil.

    Should I let London broil rest after grilling?

    Yes, resting the meat for 5-10 minutes post-grilling is essential. This allows the juices to redistribute, enhancing both flavor and tenderness.
