Ever wondered how to get that perfect sear on a London broil? You’re not alone. Many home cooks struggle with grilling this flavorful cut of meat, often ending up with something tough and chewy. But it doesn’t have to be that way.
Understanding London Broil
London broil refers to both a cooking method and a specific cut of beef. It’s known for its rich flavor and versatility, making it a favorite for grilling.
What Is London Broil?
London broil typically consists of flank steak or top round steak. It’s marinated before cooking, resulting in tender meat full of flavor. After marinating, you grill the steak quickly over high heat. This method creates delicious char and sears the outside while keeping the inside juicy. While London broil itself refers to the preparation method, the term often gets associated with the cuts of meat used.
Selecting the Right Cut
Choosing the right cut is crucial for an enjoyable London broil. Look for flank steak or top round steak, as they’re most commonly used.





- Flank Steak: This cut comes from the abdominal muscles. It’s long, flat, and flavorful but can be a bit tough if not cooked properly.
- Top Round Steak: This cut is leaner than flank steak. It offers a milder flavor and is also suitable for grilling.
When selecting your steak, look for cuts that are at least 1.5 inches thick. The marbling should be present; this intramuscular fat adds flavor and keeps the meat moist during cooking. Ensure the meat is bright red with minimal discoloration for the best quality.
Preparing the Marinade
Marinating the London broil boosts flavor and tenderness. A well-crafted marinade makes a noticeable difference in taste.
Ingredients for a Flavorful Marinade
Choose quality ingredients for your marinade. Here’s a list of essential components:
- Acid: Use ½ cup of vinegar, citrus juice (lemon or lime), or yogurt. These acids tenderize meat.
- Oil: Use ¼ cup of olive oil or vegetable oil. Oil helps to transfer flavors and keep the meat moist.
- Herbs and Spices: Add 2 teaspoons of dried herbs (like oregano or thyme), and 1 teaspoon of garlic powder or onion powder for extra depth.
- Sweetener: Use 1 tablespoon of honey, brown sugar, or maple syrup. Sweeteners balance the acidity.
- Salt and Pepper: Include 1 teaspoon of salt and ½ teaspoon of black pepper for seasoning.
Mix these ingredients in a bowl. Adjust quantities based on your taste preference, ensuring you achieve a balanced flavor profile.
Marinating Time and Techniques
Marinating time significantly affects the flavor and tenderness of the London broil.
- Duration: Marinade for at least 4 hours, but overnight yields the best results. Avoid exceeding 24 hours to prevent mushy texture.
- Technique: Place the marinade and London broil in a resealable plastic bag or shallow dish. Ensure the meat is fully submerged in the marinade.
- Refrigeration: Always marinate in the refrigerator, minimizing bacteria growth.
Consider flipping the meat halfway through the marinating process for even absorption. Properly prepared and timed, the marinade transforms your London broil into a tender, flavorful dish ready for the grill.
Grilling Techniques
Grilling London broil perfectly requires attention to detail. This section outlines essential techniques for achieving a tender and flavorful steak.





Preheating the Grill
Preheat your grill to high heat, around 450°F to 500°F. This temperature is crucial for achieving a good sear while locking in juices. Allow the grill to heat for at least 10 to 15 minutes before placing the meat on it. Use a grill thermometer for accuracy. Once heated, clean the grates with a brush to prevent sticking and ensure even cooking.
Direct vs. Indirect Heat
Use both direct and indirect heat when grilling London broil. Start with direct heat to sear the meat, enhancing the flavor and creating a crispy crust. Place the steak directly over the flame for 3 to 4 minutes per side for a medium-rare finish.
After searing, move the steak to an indirect heat area for the remaining cooking time. This method allows the inside to cook through without burning the outside. Close the grill lid during this phase to retain heat, checking the internal temperature with a meat thermometer. Aim for 130°F to 135°F for medium-rare.
Mastering these grilling techniques ensures a delicious London broil that impresses every time you fire up the grill.
Cooking the London Broil
Cooking London broil on the grill requires attention to detail for the best results. Follow these tips to ensure a perfectly cooked steak.
Recommended Cooking Times
Cooking times depend on the thickness of the steak and your preferred doneness. For a 1.5-inch thick London broil:
- Medium-Rare: Grill for about 6 to 8 minutes total, 3 to 4 minutes per side.
- Medium: Grill for about 8 to 10 minutes total, 4 to 5 minutes per side.
- Medium-Well: Grill for about 10 to 12 minutes total, 5 to 6 minutes per side.
Adjust these times if your steak is thicker or thinner. Always aim for direct heat to sear first; then move to indirect heat to finish cooking evenly.
Checking for Doneness
Checking the internal temperature ensures your London broil meets your desired doneness. Use a meat thermometer for accuracy:





- Medium-Rare: 130°F to 135°F
- Medium: 140°F to 145°F
- Medium-Well: 150°F to 155°F
Insert the thermometer into the thickest part of the meat. Remove the steak from the grill a few degrees below the target temperature, letting it rest for 5 to 10 minutes. This resting time allows juices to redistribute, resulting in a more flavorful and tender steak.
By following these guidelines, you can achieve a perfectly grilled London broil every time.
Serving Suggestions
Enjoying your perfectly grilled London broil is just the beginning. Pairing it with the right accompaniments enhances the meal.
Slicing the Meat Properly
Slicing the meat correctly is crucial for tenderness and presentation. Cut against the grain for the best results. This means identifying the direction of the muscle fibers and making perpendicular cuts. Aim for slices about 1/4 inch thick; this ensures each piece is easy to chew. Use a sharp knife for clean cuts, as a dull blade can tear the meat. After slicing, arrange the pieces on a platter to showcase your delicious work.
Accompaniments and Sides
Pair your London broil with complementary sides that balance its robust flavor. Consider the following options:
- Grilled Vegetables: Zucchini, bell peppers, and asparagus add color and nutrition. Toss them in olive oil, salt, and pepper, then grill them alongside the steak for added convenience.
- Potato Dishes: Mashed potatoes or roasted potatoes pair wonderfully with London broil. Their creamy or crispy texture offsets the meat’s chewiness.
- Salads: A fresh salad, such as a simple green salad with vinaigrette, adds a refreshing contrast. You can include ingredients like cherry tomatoes, cucumbers, and feta cheese for extra flavor.
- Bread: Slices of crusty bread or garlic bread offer a satisfying side. They can serve as a base for piling on meat or soaking up juices.
Experiment with different sides to find your favorites. Enjoy mixing and matching flavors to create a well-rounded meal.
Conclusion
Grilling a perfect London broil is all about the right preparation and technique. With a flavorful marinade and proper grilling methods, you can transform this cut into a tender and juicy masterpiece. Remember to keep an eye on the internal temperature and let the meat rest before slicing.
Pair your London broil with your favorite sides for a delicious meal that’s sure to impress. Whether it’s a summer barbecue or a cozy dinner at home, you’ll enjoy every bite of this tasty dish. Happy grilling!
