Keeping Grilled London Broil Ready for Later

• Store leftover grilled London broil in an airtight container and keep in the refrigerator for up to 3-4 days.
• Cover the sliced meat with plastic wrap or aluminum foil to prevent drying out and absorbing other food odors.
• Warm the steak in a skillet over medium-low heat with a splash of beef broth or water to maintain moisture, cooking for 2-3 minutes per side.
• Cut the meat into thin slices before refrigerating to make reheating faster and more even, preserving the meat's tenderness.

Flavor Combos to Try with Grilled London Broil

• Select bold, tannic wines like Cabernet Sauvignon or Malbec that complement the meat's rich, grilled flavor and cut through its robust protein profile.
• Create roasted rosemary potatoes or garlic-thyme grilled vegetables that enhance the marinade's complex herbal and savory undertones without overpowering the steak.
• Choose full-bodied craft beers such as amber ales or porter styles that match the London broil's deep, caramelized exterior and bring out its smoky grilled characteristics.
• Prepare a chimichurri sauce or blue cheese crumble that adds bright, tangy notes to balance the meat's deep umami flavors and provide contrasting texture.

Ways to Switch Up Your Grilled London Broil

• Herb-Infused Option: Replace part of the marinade with fresh rosemary, thyme, and sage for an aromatic Mediterranean-style flavor profile that enhances the beef's natural richness.
• Low-Sodium Alternative: Swap soy sauce with coconut aminos, reduce salt content, and use low-sodium Worcestershire sauce to create a heart-healthy version without sacrificing taste.
• Keto-Friendly Adaptation: Eliminate brown sugar, substitute with erythritol or monk fruit sweetener, and ensure all marinade ingredients are carb-conscious for a ketogenic diet approach.
• Gluten-Free Version: Use tamari instead of traditional soy sauce, confirm Worcestershire sauce is gluten-free, and verify all marinade ingredients are certified gluten-free for sensitive individuals.

Answers to Popular Grilled London Broil Questions

• What makes London broil different from other steak cuts?

London broil isn’t actually a cut of meat, but a cooking method. It’s typically made with tougher cuts like flank or top round, which require marinating and careful cooking to ensure tenderness.

• How can I tell if my London broil is cooked to the right temperature?

Use a meat thermometer. For medium-rare, aim for 130-135°F. Insert the thermometer into the thickest part of the meat without touching fat or bone for an accurate reading.

• Why is slicing against the grain important?

Cutting against the grain breaks up muscle fibers, making the meat more tender and easier to chew. Look for the direction of the muscle lines and slice perpendicular to them for the best texture.

• Can I cook London broil in the oven if I don't have a grill?

Absolutely! Preheat the oven to 400°F and use a broiler pan or cast-iron skillet. Cook for about 4-6 minutes per side, depending on thickness, to achieve similar results to grilling.

• Cracked black pepper

Step 2: Marinate with Magic

Nestle the London broil into a large zip-top bag or shallow container. Pour the marinade all over the meat, ensuring every inch gets coated. Seal and park in the refrigerator for 4-12 hours, letting the flavors mingle and transform.

Step 3: Fire Up the Grill

Crank your grill to medium-high heat, aiming for 400-450 degrees Fahrenheit. Pull the marinated steak from the refrigerator and let it chill at room temperature for 20-30 minutes.

Chef-Approved Advice for Grilled London Broil

• Marinate Deeply for Maximum Flavor: Let the London broil soak in the marinade overnight to allow the complex blend of soy sauce, balsamic, and Worcestershire to penetrate deeply into the meat, creating a rich, layered taste.
• Slice Against the Grain: Cut the cooked steak perpendicular to the muscle fibers to break down tough connective tissues, ensuring each bite is supremely tender and easy to chew.
• Control Grill Temperature Precisely: Maintain a consistent medium-high heat around 400-450F to achieve a perfect sear without burning, which helps develop a delicious caramelized exterior while keeping the inside juicy.
• Rest Meat for Optimal Juiciness: Allow the grilled steak to rest for 10 minutes after cooking, letting the internal juices redistribute throughout the meat, which prevents dryness and preserves the steak's natural moisture.
• Choose Lean Cuts Wisely: Select a top round or flank steak with minimal fat marbling for an authentic London broil experience, ensuring a lean yet flavorful protein that absorbs marinades beautifully.

Instructions

1. Craft a robust marinade by whisking together olive oil, soy sauce, balsamic vinegar, Worcestershire sauce, lemon juice, minced garlic, brown sugar, Dijon mustard, black pepper, and onion powder in a medium mixing bowl.
2. Transfer the London broil into a large zip-top bag or shallow container, then thoroughly coat the meat with the prepared marinade. Seal and refrigerate for a minimum of 4 hours, preferably overnight to enhance flavor penetration.
3. Remove the marinated steak from the refrigerator approximately 30 minutes before grilling to allow it to reach room temperature. Meanwhile, prepare the grill by heating it to medium-high heat, targeting around 400-450°F.
4. Drain excess marinade from the meat and place the London broil directly on the preheated grill grates. Cook for 5-7 minutes on each side, aiming for a medium-rare doneness with an internal temperature of 130-135°F.
5. Once grilled to desired doneness, transfer the steak to a cutting board and let it rest for 10 minutes. This crucial resting period allows the meat’s juices to redistribute, ensuring maximum tenderness.
6. After resting, slice the London broil thinly against the grain to maximize tenderness. Optional: garnish with fresh parsley and serve alongside roasted vegetables, a crisp salad, or herb-roasted potatoes.

Notes

• Customize the marinade by swapping soy sauce for tamari to make the recipe gluten-free, ensuring everyone can enjoy this delicious dish.
• Cut cooking time by pounding the meat thinner, which helps the London broil cook more evenly and absorb marinade flavors faster.
• Use a meat thermometer for precise doneness, preventing overcooking and maintaining the steak’s juicy, tender texture.
• Leftover grilled London broil transforms beautifully into next-day sandwiches or salad toppers, maximizing your meal prep efficiency.
