Understanding London Broil
Understanding London broil helps you achieve the best results on the grill. This cut of beef usually comes from the flank or round part of the cow, delivering rich flavors when cooked properly.
What Is London Broil?
London broil refers to both a cooking method and a specific cut of meat. Traditionally, it involves marinating and grilling meat at high temperatures. While “London broil” is often used to describe flank steak, it can also refer to other cuts such as top round or sirloin. The key is to cook the meat quickly and slice it against the grain for the best texture.
- Flank Steak: Known for its robust flavor and thinner profile, flank steak is a popular choice for London broil. It absorbs marinades well and benefits from quick, high-heat cooking.
- Top Round Steak: This cut is leaner than flank and offers a similar taste. It’s a good option if you prefer a less fatty cut.
- Sirloin Steak: Sirloin provides great flavor and tenderness. While not as common, it works well for London broil preparation.
- Hanger Steak: Often overlooked, hanger steak has a deep, beefy flavor. Its tenderness makes it suitable for grilling as a London broil.
Selecting the right cut plays a crucial role in achieving optimal grilling results. Always consider the marbling and tenderness of the meat for the best possible outcome on your grill.





Preparing Your London Broil for Grilling
Preparing your London broil for grilling enhances flavor and tenderness. Focus on marinating and seasoning for the best results.
Marinating Options
Selecting a good marinade makes a significant difference. Consider using a mixture of acidic components and flavorings. Here are some popular options:
- Soy Sauce: Adds umami and depth.
- Vinegar: Tenderizes with acidity; balsamic or red wine vinegar works well.
- Citrus Juices: Fresh lemon or lime juice brightens flavor.
- Oil: Olive oil or sesame oil helps retain moisture.
Combine these ingredients and marinate your steak for at least 30 minutes, up to 24 hours for maximum flavor. A longer marinating time helps break down tough fibers.
Seasoning Tips
Proper seasoning enhances the natural flavors of your London broil. Here are effective seasoning strategies:
- Salt and Pepper: Use kosher salt and freshly ground black pepper for basic seasoning.
- Garlic Powder: Adds depth; sprinkle generously.
- Onion Powder: Complements garlic; use in moderation.
- Herbs: Fresh herbs like rosemary and thyme pair nicely with grilled meats.
Even if you use a marinade, additional seasoning right before grilling boosts flavor. Apply the seasoning evenly on all sides for a balanced taste.
Cooking Times for London Broil on Grill
Cooking London broil on the grill requires precise timing for the best flavor and tenderness. Specific cooking times depend on the cut of meat and the desired level of doneness.
Recommended Cooking Times
- Rare (120-125°F): Grill for 4-5 minutes per side.
- Medium Rare (130-135°F): Grill for 6-7 minutes per side.
- Medium (140-145°F): Grill for 8-9 minutes per side.
- Medium Well (150-155°F): Grill for 10-11 minutes per side.
- Well Done (160°F and above): Grill for 12-13 minutes per side.
Use a meat thermometer to check internal temperatures. Always let the meat rest for about 5-10 minutes after grilling to allow juices to redistribute.





- Thickness of the Cut: Thicker cuts require longer cooking times. A 1-inch thick piece cooks faster than a 2-inch thick piece.
- Grill Temperature: Preheating the grill should reach a temperature of around 450°F. Higher temperatures cook meat faster but may cause charring.
- Marinade: Marinated meat could cook differently, sometimes quicker, due to acidic ingredients. Adjust cooking time based on the marinade used.
- External Conditions: Wind, humidity, and altitude can influence cooking times. Wind can cool your grill, while humidity can affect moisture levels in the meat.
- Resting Time: Allowing meat to rest influences carryover cooking. During resting, internal temperature can rise by 5-10°F.
By considering these factors, you can achieve juicy, flavorful London broil every time.
Grill Temperature and Techniques
Grilling London broil at the right temperature and using effective techniques ensures juicy, flavorful results. Focus on high heat and the appropriate cooking methods for optimal outcomes.
Ideal Grill Temperature
Aim for a grill temperature between 400°F and 450°F. This high temperature sears the outside quickly, locking in juices while maintaining tenderness. For best results, preheat your grill for at least 15 minutes. If using a charcoal grill, let the coals ash over and reach a steady heat before placing the meat on the grates. Tongue might get tempted to check constantly, but resist this urge. Keep the lid closed to maintain temperature and prevent flare-ups.
Cooking Methods: Direct vs. Indirect Heat
Utilize both direct and indirect heat methods for grilling London broil effectively.
- Direct Heat: Place the meat directly over the heat source. This method works well for quick cooking and searing. Grill each side for about 4 to 7 minutes, depending on thickness. Monitor closely for desired doneness.
- Indirect Heat: For thicker cuts, start with direct heat to sear and seal in flavors, then transfer the meat to a cooler part of the grill. Cover the grill and cook until the internal temperature reaches your desired level. This method reduces the risk of burning the outside while ensuring the inside cooks evenly.
By mastering grill temperature and techniques, you enhance the flavor and texture of your London broil, guaranteeing a delicious meal.
Resting and Slicing Your London Broil
Resting and slicing your London broil correctly can elevate your grilling experience. Following these steps will ensure maximum flavor and tenderness.
Importance of Resting
Resting your London broil after grilling allows the juices to redistribute throughout the meat. Some crucial points include:
- Resting Time: Let the meat rest for 10 to 15 minutes. This period prevents juices from escaping when you slice.
- Covering: Tent the meat with aluminum foil during resting. This keeps it warm while the juices settle.
- Temperature Increase: Expect a slight rise in temperature while resting. This phenomenon is known as carryover cooking, which can enhance doneness.
How to Slice for Maximum Tenderness
Slicing your London broil properly can enhance its tenderness and flavor. Keep these guidelines in mind:





- Against the Grain: Identify the direction of the grain in the meat. Always slice against it. This cuts the muscle fibers, making each bite more tender.
- Thin Slices: Aim for slices about 1/4 inch thick. Thin slices provide a more enjoyable texture and help with easier chewing.
- Angle: Slice at a slight angle for greater surface area. An angled cut not only looks attractive but also enhances mouthfeel.
Following these guidelines ensures that your London broil turns out juicy and tender, making for a satisfying meal.
Conclusion
Grilling a perfect London broil doesn’t have to be a daunting task. By understanding the right cooking times and techniques you can achieve that juicy and flavorful result every time. Remember to choose the right cut and don’t skip on marinating and seasoning to enhance those delicious flavors.
Pay attention to your grill temperature and utilize both direct and indirect heat for the best outcomes. And don’t forget the importance of resting and slicing against the grain to keep your meat tender. With these tips in mind you’re well on your way to impressing family and friends with your grilling skills. Enjoy your next London broil feast!
