Understanding London Broil
London broil refers to a cooking method as well as a specific cut of meat. It’s popular for its rich flavor and ability to serve a crowd without breaking the bank.
What Is London Broil?
London broil typically involves flank steak or top round. This cut comes from the belly or the upper leg of the cow. When cooked properly, it offers a hearty, beefy taste. The key to London broil is marination. Marinating enhances flavor and tenderizes the meat, making it easier to chew. Common marinade ingredients include soy sauce, vinegar, garlic, and various herbs.
Choosing the Right Cut
Choosing the right cut is crucial for a successful London broil. Here are the two popular options:





- Flank Steak: Known for its rich flavor, flank steak has a pronounced grain. It requires slicing against the grain after cooking for optimal tenderness.
- Top Round: This cut is leaner than flank steak. Although it’s slightly tougher, it absorbs marinades well, resulting in a flavorful dish.
When selecting meat, look for cuts that have some marbling. This fat enhances juiciness and flavor during cooking. Always choose fresh, high-quality meat for the best results.
Preparing the London Broil
Preparing a London broil involves marinating and seasoning to enhance its flavor and tenderness.
Marinating Tips
Marinate your London broil for at least four hours, but overnight is best. A good marinade includes soy sauce, vinegar, garlic, and your choice of herbs. These ingredients help tenderize the meat while infusing it with flavor. Consider using a resealable plastic bag for easy marination and to ensure all surfaces are coated. Flip the bag occasionally to promote even flavor absorption.
Seasoning Options
Season your London broil just before grilling. Simple salt and black pepper work well, but you can explore more complex seasonings. Try garlic powder, onion powder, or smoked paprika for added depth. For a spicy kick, consider crushed red pepper flakes. Ensure an even coating to enhance the overall taste. Remember, less is often more when it comes to seasoning your steak, as you want the natural flavor to shine through.
Cooking on a Gas Grill
Cooking a London broil on a gas grill requires proper preparation and technique for optimal results. Follow these steps for a tender, flavorful steak.
Preheating the Gas Grill
Preheat the gas grill for at least 10 to 15 minutes before cooking. Set the burners to high to create a consistent, hot cooking environment. Aim for a temperature between 450°F and 500°F. This high heat helps achieve a nice sear on the outside while keeping the inside juicy.
- Searing: Start by placing the marinated London broil directly on the hottest part of the grill. Sear each side for about 4 to 6 minutes, depending on the thickness of the meat. Look for a nice caramelized crust.
- Indirect Heat: Once seared, move the steak to a cooler part of the grill. This allows it to cook through gently. Cover the grill and cook for an additional 10 to 15 minutes, checking the internal temperature with a meat thermometer.
- Target Temperature: Aim for an internal temperature of 130°F to 135°F for medium-rare. Remember, it’s better to undercook slightly since the steak continues to cook as it rests.
- Resting: After grilling, let the London broil rest for 10 minutes. This allows the juices to redistribute, resulting in a juicier steak. Avoid cutting into it immediately.
- Slicing: Slice the steak against the grain for maximum tenderness. Thin slices enhance the eating experience and make the flavors more pronounced.
Experiencing the right cooking techniques enables you to achieve the best London broil on a gas grill, ensuring a delicious meal every time.





Checking Doneness
Knowing when your London broil is perfectly cooked ensures a delicious and satisfying meal. Using an accurate method to check for doneness makes it easy to gauge the meat’s internal temperature.
Internal Temperature Guide
Aim for specific internal temperatures to achieve the desired level of doneness. Here’s a quick reference:
Doneness Level | Internal Temperature |
---|---|
Rare | 120°F to 125°F |
Medium Rare | 130°F to 135°F |
Medium | 140°F to 145°F |
Medium Well | 150°F to 155°F |
Well Done | 160°F and above |
Use a meat thermometer to check the thickest part of the steak for accuracy. Don’t forget that the steak continues to cook as it rests, so remove it from the grill a few degrees below your target temperature.
Resting the Meat
Resting your London broil is crucial for a tender result. After grilling, let the meat rest for about 10 minutes. This resting period allows juices to redistribute throughout the meat, enhancing flavor and moisture.
Place the steak on a cutting board and loosely cover it with aluminum foil to keep it warm. Avoid cutting into it too soon, as this releases juices and can result in a drier steak. Slice against the grain for maximum tenderness and enjoy your perfectly cooked London broil.
Serving Suggestions
Serving your grilled London broil with the right accompaniments enhances the meal experience.
Side Dishes to Complement
Consider these delectable side dishes to complete your London broil meal:
- Grilled Vegetables: Asparagus, bell peppers, and zucchini add vibrant color and flavor.
- Baked Potatoes: Serve with butter and sour cream for a hearty option.
- Garlic Mashed Potatoes: They pair well with the rich taste of the steak.
- Caesar Salad: Crisp romaine and tangy dressing balance the meal.
- Coleslaw: This adds crunch and a refreshing contrast to the savory meat.
These options not only elevate your meal but also introduce different textures and flavors.





Slicing Tips
Proper slicing ensures tenderness and enhances presentation. Follow these tips:
- Slice Against the Grain: Identify the direction of the muscle fibers and cut across them. This technique breaks up the fibers, making each bite tender.
- Use a Sharp Knife: A sharp knife prevents tearing the meat, ensuring clean cuts.
- Cut into Thin Strips: Aim for slices around ¼ inch thick for optimal portion sizes.
- Let It Rest: Allow the cooked steak to rest before slicing. This step retains juicy flavors.
Implementing these serving suggestions and slicing techniques will transform your London broil into a memorable dish.
Conclusion
Cooking a London broil on your gas grill can be a rewarding experience that impresses family and friends. With the right marinade and cooking techniques you can achieve a juicy and flavorful steak that’s sure to be a hit at your next gathering.
Don’t forget to let your steak rest before slicing to ensure every bite is tender and packed with flavor. Pair it with your favorite sides and you’ve got a meal that’s not just delicious but also memorable.
So fire up that grill and enjoy the delicious results of your hard work. Happy grilling!
