How Long to Cook London Broil on Grill: A Complete Guide for Perfectly Grilled Steak

Wondering how long to cook London broil on the grill? You’re not alone. Many home cooks face the challenge of getting this flavorful cut just right. Overcooked meat can be tough and chewy, while undercooked meat can leave you worried about safety.

Understanding London Broil

London broil refers to a cooking method as much as it does a specific cut of meat. It typically involves marinating tougher cuts of beef, then grilling or broiling at high heat to tenderize the protein. This technique allows you to enjoy a flavorful and affordable cut that’s perfect for gatherings.

What Is London Broil?

London broil is a culinary method originating from North America rather than a designated cut of beef. It’s most often associated with flank steak or top round steak, both of which require marinating and quick cooking to enhance tenderness. The process usually involves cooking the meat to a medium-rare doneness, around 130-135°F, before letting it rest for optimal flavor.

Cuts of Meat Suitable for London Broil

Several cuts of meat work well for a London broil. Popular choices include:

• Flank Steak: Known for its rich flavor, flank steak is lean and benefits from marinating.
• Top Round Steak: This cut is affordable and has good flavor when cooked correctly.
• Sirloin Steak: This cut offers tenderness and flavor, making it a versatile choice.
• Skirt Steak: This cut is flavorful but can be tougher, requiring marination for the best results.

Selecting the right cut is essential for achieving juicy, tender meat when grilling.

Preparing London Broil for Grilling

Preparing London broil properly sets the foundation for a delicious meal. Start with marinating the meat and follow up with proper seasoning.

Marinating the Meat

Marinating enhances the flavor and tenderness of London broil. Use a mixture of acidic ingredients, such as vinegar, citrus juice, or wine, combined with oil and spices. Aim for a 4- to 8-hour marinating period for optimum results.

• Choose ingredients like soy sauce, garlic, and herbs for a savory marinade.
• For a sweeter touch, consider adding brown sugar or honey.
• Place the meat in a resealable bag or shallow dish to ensure even coverage.

Seasoning Tips

Seasoning enhances the natural flavor of the meat. A good seasoning blend includes salt, pepper, and herbs.

• Apply a generous amount of salt about 30 minutes before grilling to draw out moisture.
• Use freshly ground pepper for added spice.
• Sprinkle dried herbs, like thyme or rosemary, for an aromatic touch.

Make sure to rub the seasoning evenly over the entire piece of meat to ensure a well-rounded flavor. Get creative and adjust the seasonings based on personal taste preferences, but keep it simple to allow the meat’s flavor to shine through.

Cooking London broil on the grill requires precise timing to ensure juicy, tender meat. Follow these guidelines for the best results.

Recommended Cooking Times

• Medium-Rare (130-135°F): Grill for 4-5 minutes per side.
• Medium (135-145°F): Grill for 5-6 minutes per side.
• Medium-Well (145-155°F): Grill for 6-7 minutes per side.
• Well Done (155°F and above): Grill for 8-10 minutes per side.

Using a meat thermometer helps ensure accuracy. Insert it into the thickest part of the meat without touching bone or fat. After cooking, let the meat rest for 5-10 minutes to allow juices to redistribute.

• Thickness of the Cut: Thicker cuts require longer cooking times. Aim for a thickness of around 1 to 1.5 inches for optimal grilling.
• Grill Temperature: High heat (450-500°F) produces a good sear. If your grill temperature is lower, increase cooking times accordingly.
• Marinade Content: Marinades high in sugar can caramelize quickly, leading to faster cooking. Monitor closely to prevent burning.
• Desired Doneness: The internal temperature will rise slightly after removal from the grill, so account for that when timing.
• Altitude: Higher altitudes may require adjustments to cooking times due to decreased air pressure.

These tips ensure you achieve the perfect doneness for your London broil on the grill.

Best Practices for Grilling London Broil

Grilling London broil requires attention to detail for the best results. Follow these best practices to ensure a flavorful and tender outcome.

Checking Doneness

To check the doneness of your London broil, use a meat thermometer. Insert it into the thickest part of the meat. Here are the target temperatures for various doneness levels:

• Medium-Rare: 130-135°F
• Medium: 135-145°F
• Medium-Well: 145-155°F
• Well Done: 160°F and above

Avoid cutting into the meat to check doneness; this releases juices and can dry it out. Instead, rely on the thermometer for accuracy. After grilling, let the meat rest for 5-10 minutes. This helps retain juices and enhances flavor.

Slicing Techniques

Slicing London broil correctly is key to enjoying its tenderness. Always slice against the grain. This shortens muscle fibers, making each bite easier to chew. Here’s how to slice effectively:

1. Identify the grain of the meat by observing the direction of the muscle fibers.
2. Position the knife perpendicular to the grain. Aim for a diagonal angle to enhance presentation.
3. Cut thin slices, ideally about 1/4 inch thick.

Proper slicing also helps distribute the juices evenly, maximizing flavor. Enjoy it sliced over a salad, in a sandwich, or on its own.

Conclusion

Grilling London broil can be a rewarding experience when you know the right techniques and timings. By focusing on marinating and properly seasoning your meat you can elevate the flavors and tenderness. Remember to keep an eye on the cooking times for your preferred doneness and always use a meat thermometer for precision.

After grilling let your London broil rest before slicing to keep those juices locked in. With the right approach you’ll enjoy a delicious meal that’s sure to impress. So fire up that grill and get ready to savor every bite of your perfectly cooked London broil.
