The Ultimate London Broil Marinade: A Symphony of Flavors

I can still picture my grandfather, apron smeared with barbecue sauce, carefully arranging slices of London broil on a platter. The aroma alone was enough to transport me to summer evenings filled with laughter and the comforting crackle of charcoal. He always swore his secret was a marinade passed down through generations. While his recipe remains a treasured family secret, this London broil marinade, discovered years later, evokes a similar sense of nostalgia and that familiar, deeply savory flavor. It’s a journey back to those cherished memories with every delicious bite.

Recipe Overview

• Prep Time: 15 minutes
• Cook Time: Variable, depending on desired doneness
• Total Time: 8 hours 15 minutes (includes marinating time)
• Servings: 4
• Dietary Type: Gluten-Free (check Worcestershire and Soy Sauce labels), Dairy-Free

Ingredients

• 2 garlic cloves, minced
• 1 tablespoon red wine vinegar
• 1 tablespoon balsamic vinegar
• 2 tablespoons lemon juice
• 1 1/2 tablespoons Dijon mustard
• 1 tablespoon Worcestershire sauce
• 1/2 tablespoon soy sauce
• 1/2 teaspoon oregano
• 1/2 teaspoon basil
• 1/2 teaspoon thyme
• 1/3 cup olive oil

Equipment Needed

• Glass bowl
• Whisk
• Refrigerator
• Grill

Instructions

1. In a glass bowl, combine the minced garlic, red wine vinegar, balsamic vinegar, and lemon juice. The acidity in these ingredients tenderizes the meat and infuses it with bright flavors.

2. Add the Dijon mustard, Worcestershire sauce, and soy sauce to the bowl. The Dijon mustard acts as an emulsifier, helping the marinade cling to the meat. Worcestershire sauce adds depth and umami, while soy sauce provides a salty, savory note. Remember to check the labels on these sauces for gluten if needed.

3. Incorporate the dried herbs: oregano, basil, and thyme. These classic Italian herbs contribute aromatic complexity to the marinade. Ensure your dried herbs are relatively fresh for the best flavor.

4. Gradually whisk in the olive oil until the marinade is well combined. The olive oil helps to distribute the flavors evenly and prevents the meat from drying out during grilling.

5. Place a 1-2 lb London broil in the marinade, ensuring it is thoroughly coated. A large, resealable bag or a shallow dish works well for this. If using a dish, turn the meat occasionally to ensure even marination.

6. Refrigerate the London broil in the marinade overnight, or for at least 8 hours. This allows the flavors to penetrate deep into the meat and tenderize the fibers. The longer it marinates, the more flavorful and tender the London broil will be.

7. Preheat your grill to medium-high heat. Ensure the grates are clean and lightly oiled to prevent sticking.

8. Remove the London broil from the marinade and discard the marinade. Do not reuse the marinade, as it has been in contact with raw meat.

9. Grill the London broil for 4-6 minutes per side for medium-rare, or longer depending on your desired level of doneness. Use a meat thermometer to ensure accuracy. The internal temperature should reach 130-135°F for medium-rare, 135-145°F for medium, and 145-155°F for medium-well.

10. Once cooked to your liking, remove the London broil from the grill and let it rest for at least 10 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful final product. Tent it loosely with foil to keep it warm.

11. Slice the London broil thinly against the grain. This is crucial for tenderness, as it shortens the muscle fibers.

Expert Tips & Tricks

• Poking the Meat: Avoid piercing the London broil with a fork while grilling, as this will release valuable juices and dry out the meat. Use tongs to flip it.
• Marinating Time: While 8 hours is good, 24 hours is even better! Just make sure the marinade isn’t too acidic if marinating for longer periods, which can negatively affect the meat’s texture.
• Flavor Boost: For an extra layer of flavor, add a pinch of red pepper flakes to the marinade for a subtle kick.
• Grill Marks: To achieve perfect grill marks, rotate the London broil 45 degrees halfway through cooking each side.
• Doneness Check: Use a reliable instant-read thermometer to ensure the London broil is cooked to your desired doneness. Remember that the internal temperature will rise slightly as the meat rests.
• Resting: The resting period is critical! Don’t skip it.

Serving & Storage Suggestions

Serve the sliced London broil immediately. It’s fantastic on its own, with a side of roasted vegetables, mashed potatoes, or a fresh salad. It also makes a delicious addition to sandwiches or wraps.

Storage: Leftover London broil can be stored in an airtight container in the refrigerator for up to 3-4 days.

Reheating: To reheat, gently warm the sliced London broil in a skillet over low heat, or in the microwave. Be careful not to overcook it, as it can become dry. Adding a little beef broth or the original marinade (if reserved before marinating raw meat) can help retain moisture. Sliced London Broil freezes well for up to 2-3 months. Wrap tightly in freezer-safe plastic wrap, and place it in a freezer bag, expelling as much air as possible. Thaw overnight in the refrigerator before reheating.

FAQs (Frequently Asked Questions)

Q: Can I marinate the London broil for longer than 8 hours?
A: Yes, you can marinate it for up to 24 hours, but be mindful of the acidity of the marinade, as it can start to break down the meat fibers if left too long.

Q: Do I need to rinse the London broil after marinating?
A: No, there’s no need to rinse it. Just remove it from the marinade and pat it dry with paper towels before grilling.

Q: What is the best way to slice London broil?
A: Always slice against the grain. Look for the direction of the muscle fibers and slice perpendicular to them for the most tender result.

Q: Can I cook London broil in the oven instead of grilling?
A: Yes, you can broil it in the oven. Preheat your broiler and place the marinated London broil on a broiler pan. Broil for 5-7 minutes per side, or until it reaches your desired level of doneness.
