How Long To Grill London Broil Medium Rare?

To achieve a medium-rare finish for London broil, which is generally characterized by an internal temperature of 130°F to 135°F (54°C to 57°C), you should grill it for about 6 to 8 minutes on each side. Always use a meat thermometer for accuracy.

Understanding London Broil

London broil refers to both a cooking method and a specific cut of meat, typically from the flank steak or top round. This cut is known for being lean and flavorful, but it can also be tough if not cooked properly. To maximize tenderness, marinating and slicing against the grain are essential steps.

Temperature and Timing

Grilling is not just about time; it’s also about temperature. Here are the specific temperature guidelines to follow:

  • Rare: 120°F to 125°F (49°C to 52°C)
  • Medium Rare: 130°F to 135°F (54°C to 57°C)
  • Medium: 140°F to 145°F (60°C to 63°C)
  • Medium Well: 150°F to 155°F (66°C to 68°C)
  • Well Done: 160°F and above (71°C and up)

Preparing the London Broil

Before you start grilling, specific preparations are important to ensure the meat stays flavorful and tender. Here’s how to get started:

Choosing Your Cut

When selecting a London broil, look for a cut that is bright red in color with some marbling of fat. This will help keep the meat moist during grilling. Avoid any cuts that appear gray or have excessive gristle.

Marinating the Meat

Marinating London broil not only adds flavor but also helps to break down tough fibers. Here’s a simple marinade you can try:

  • 1/2 cup soy sauce
  • 1/4 cup olive oil
  • 1/4 cup red wine vinegar
  • 3 cloves garlic, minced
  • 1 tablespoon Worcestershire sauce
  • 1 tablespoon brown sugar
  • Salt and pepper to taste

Combine these ingredients in a bowl, then add your London broil. Marinate for at least 2 hours, or up to 24 hours for more depth of flavor.

The Grilling Process

Once your meat is marinated, it’s time to grill. Follow these steps for the best results:

  1. Preheat the Grill: Preheat your grill to high heat (about 450°F to 500°F or 232°C to 260°C).
  2. Remove the Meat from Marinade: Take the London broil out of the marinade and discard the marinade to prevent flavor contamination.
  3. Pat Dry: Pat the meat dry with a paper towel. This will help create a nice sear when grilling.
  4. Season: Season with salt and pepper or any additional spices you desire.
  5. Grill: Place the meat on the grill and cook for 6 to 8 minutes on one side. Flip the meat and cook for another 6 to 8 minutes.
  6. Check Temperature: Use a meat thermometer to check the internal temperature. For medium-rare, remove from the grill when it reaches 130°F to 135°F (54°C to 57°C).
  7. Rest the Meat: Let the cooked London broil rest for 10 minutes before slicing. This allows juices to redistribute throughout the meat.

Common Mistakes to Avoid

Avoiding common pitfalls is essential for successful grilling. Here are some mistakes to watch out for:

  • Overcooking: Keep an eye on cooking time and internal temperature; overcooked London broil can become tough and chewy.
  • Not Using a Thermometer: Relying on color alone can be misleading. A meat thermometer is the best tool for accuracy.
  • Skipping the Resting Period: Cutting into the meat too soon can lead to a loss of juices, making it dry.

Serving Suggestions

London broil is incredibly versatile and can be served in various ways. Here are a few ideas:

  • Slice thinly against the grain and serve on a platter with chimichurri sauce for a fresh touch.
  • Serve the sliced meat in sandwiches or wraps with fresh vegetables.
  • Pair with grilled vegetables or a fresh salad for a complete meal.

Preparing Ahead

Grilling London broil can be made easier with some advance preparation:

  • Marinate the Night Before: If you’re hosting a gathering, marinate your meat the night before for deeper flavors.
  • Slice Ahead of Time: Depending on your serving style, you can slice the meat ahead of time and keep it covered until ready to serve.

Storing and Reheating Leftovers

If you have any leftover London broil, proper storage and reheating methods are crucial to maintain flavor and texture:

  • Store leftovers in an airtight container in the refrigerator for up to 3 days.
  • To reheat, place slices in a pan over medium heat, adding a splash of broth or water to keep it moist.
