Understanding London Broil
London broil refers to a cooking method as well as a specific cut of meat. Understanding its characteristics enhances your grilling experience. This affordable cut can yield impressive results when cooked properly.
What Is London Broil?
London broil typically comes from tougher cuts of beef, like flank or top round steak. It’s known for its bold flavor and fibrous texture. The term “London broil” originally described a preparation technique, involving marinating and broiling. The meat is grilled quickly at high temperatures, producing a flavorful outer crust while retaining juiciness inside.
Best Cuts for London Broil
Select beef cuts that work best for London broil grilling. Here are the top options:





- Flank Steak
Flank steak is lean with a rich beefy flavor. Its graininess makes it ideal for marinating, helping break down toughness.
- Top Round Steak
Top round steak, while slightly tougher, is economical and flavorful. Proper marinating and slicing against the grain yield satisfying results.
- Sirloin Tip
Sirloin tip offers tenderness and robust flavor. It cooks well on the grill and absorbs marinades effectively.
Choosing the right cut ensures you enjoy a delicious and satisfying London broil.
Preparing the Marinade
Marinating adds flavor and softens the fibrous texture of London broil. A good marinade is key to achieving a delicious grilled steak.
Key Ingredients for Marinade
- Oil: Use olive oil or vegetable oil. Oil helps infuse flavors while keeping the meat moist.
- Acid: Incorporate vinegar (balsamic or red wine) or citrus juice (like lemon). Acid helps tenderize the meat.
- Salt: Add kosher or sea salt. Salt enhances flavor and helps retain moisture during grilling.
- Sweetener: Include brown sugar or honey. Sweetness balances acidity and adds caramelization.
- Herbs and Spices: Use fresh or dried garlic, onion powder, black pepper, or rosemary. Herbs elevate flavor profiles.
- Soy Sauce: Consider adding soy sauce for umami. It deepens flavor and contributes to color.
- Time Matters: Marinade for at least 2 hours, but no more than 24 hours. This timeframe strikes a balance between flavor absorption and over-tenderizing.
- Seal It Up: Use a zip-top bag or a glass container to marinate. This ensures even coverage and makes cleanup simple.
- Refrigerate: Always marinate in the fridge to keep the meat safe. Avoid leaving it out at room temperature.
- Massage the Marinade: Gently massage the marinade into the meat. This allows for deeper penetration of flavors.
- Pat Dry Before Grilling: Remove excess marinade with paper towels before grilling. This helps achieve a better sear and prevents flare-ups.
Cooking Techniques
Cooking London broil on a grill requires a few essential techniques to ensure a tasty and tender outcome. Use the following methods for a perfect grilling experience.
Prepping the Grill
Prepping your grill sets the stage for a great London broil.





- Clean the Grate: Scrub the grill grates with a brush until they’re free from debris. A clean grill prevents sticking and enhances flavor.
- Oil the Grates: Use a paper towel soaked in oil and tongs to coat the grates lightly. This helps reduce sticking and promotes even cooking.
- Preheat the Grill: Heat the grill to high, around 450°F to 500°F. Preheating ensures a proper sear, locking in juices and flavors.
- Set Up for Two-Zone Cooking: Allocate one side of the grill for direct heat and the other for indirect heat. This method allows for searing and finishing cooking at a gentler temperature.
Cooking Times and Temperatures
Focus on cooking times and temperatures for the best results.
- Sear First: Once the grill reaches the desired temperature, place the marinated London broil on the direct heat side. Sear each side for about 4 to 6 minutes, developing those flavorful grill marks.
- Move to Indirect Heat: After searing, transfer the steak to the cooler side of the grill. Close the lid and allow it to cook indirectly. Aim for an internal temperature of 135°F for medium-rare, which takes about 10 to 15 minutes.
- Rest Before Slicing: After removing the steak from the grill, let it rest for at least 5 to 10 minutes. Resting redistributes the juices and prevents them from leaking out when you slice the meat.
- Slice Against the Grain: When ready to serve, cut the London broil against the grain. This technique ensures tender bites and maximizes flavor with each slice.
Grilling the London Broil
Grilling London broil creates a delicious meal with proper technique. Follow these steps to achieve a perfectly cooked steak.
Searing the Meat
Start by placing the marinated London broil directly over the hottest part of the grill. Sear the meat for 4 to 6 minutes without moving it. This creates a nice crust. Searing locks in juices and enhances flavor. After this time, it’s essential to check for grill marks before flipping.
Flipping and Checking Doneness
Flip the steak using tongs, being gentle to preserve the crust. Sear the other side for another 4 to 6 minutes. During this phase, utilize an instant-read meat thermometer to check the internal temperature. Aim for 135°F for medium-rare. If it’s not close, transfer the steak to the cooler part of the grill. Close the lid and allow for indirect cooking. Continue checking until it reaches your desired doneness, keeping in mind that it will rise a few degrees while resting.
Serving Suggestions
Serving London broil can elevate your meal and impress your guests. Focus on slicing and pairing to enhance the dining experience.
Slicing Tips for Optimal Flavor
Slice the London broil against the grain to maximize tenderness. Identifying the direction of the muscle fibers helps in slicing. Aim for thin slices, about 1/4 inch thick. Arrange the slices on a platter for visual appeal. Drizzle any remaining marinade or a balsamic reduction over the meat for added flavor.
Accompaniments and Sides
Select sides that complement the bold flavor of London broil. Here are some popular options:
- Grilled Vegetables: Asparagus, bell peppers, and zucchini provide a colorful and healthy contrast.
- Potato Dishes: Consider twice-baked potatoes or garlic mashed potatoes for a hearty pairing.
- Salads: A fresh arugula salad with lemon vinaigrette balances the richness of the meat.
- Bread: Serve with crusty bread or garlic bread to soak up juices.
Mix and match these accompaniments for a well-rounded meal.
