• Olive oil
• Soy sauce
• Balsamic vinegar
• Worcestershire sauce
• Fresh lemon juice
• Minced garlic
• Brown sugar
• Dijon mustard
• Cracked black pepper

Step 2: Bathe the Steak in Deliciousness

Transfer the London broil into a large zip-top bag or shallow container. Pour the marinade over the meat, ensuring every inch gets coated. Seal tightly and pop into the refrigerator. Let it soak up all those incredible flavors for 4-8 hours or overnight for maximum taste explosion.

Step 3: Fire Up the Grill

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

Step 4: Perfectly Sear the Meat

Step 5: Let the Meat Rest and Slice

Remove the steak from the grill and let it rest for 10 minutes. This magical pause allows juices to redistribute, ensuring each bite is incredibly tender. Slice against the grain using a sharp knife to maximize tenderness.

Step 6: Serve with Flair

Plate your masterpiece with a sprinkle of fresh chopped parsley. Pair with roasted vegetables, a crisp salad, or golden potato wedges for a complete meal that’ll impress everyone at the table.

Tips For Grilled London Broil Success

• Maximize Marinade Magic: Let the London broil soak in the marinade overnight to absorb maximum flavor and tenderize the meat deeply. The longer it marinates, the more delicious and tender it becomes.
• Temperature Precision Matters: Use a meat thermometer to check internal temperature for perfect doneness. Medium-rare hits around 130-135°F, ensuring juicy and flavorful results every time.
• Slice Like a Pro: Always cut the steak against the grain to break down muscle fibers, creating incredibly tender and melt-in-your-mouth slices that are easy to chew.
• Rest for Juiciness: Allow the grilled steak to rest for 10 minutes after cooking, which helps redistribute juices and prevents moisture loss when cutting, guaranteeing a succulent dining experience.
• Grill Mastery Tip: Preheat the grill to medium-high heat and let the steak sit at room temperature before grilling to ensure even cooking and beautiful caramelization on the outside.

Best Way To Store Grilled London Broil

• Refrigerate leftover London broil in an airtight container for up to 3-4 days.
• Wrap slices individually in plastic wrap or aluminum foil to prevent moisture loss and maintain tenderness.
• Store in the coldest part of your refrigerator, typically the back shelf.
• When reheating, use gentle methods like low-temperature oven warming or quick microwave pulses to prevent drying out the meat.
• Freeze sliced London broil for longer storage, placing portions in freezer-safe bags with excess air removed.
• Frozen slices will keep well for 2-3 months.
• Thaw overnight in the refrigerator before reheating to preserve the meat's original texture and flavor.
• Always reheat to an internal temperature of 165°F to ensure food safety and prevent bacterial growth.

What Goes Best With Grilled London Broil

• Pair with Bold Red Wine: Select a robust Cabernet Sauvignon or Syrah to complement the rich, grilled meat's intense flavors and cut through its savory profile.
• Match with Roasted Vegetable Medley: Create a harmonious side dish of herb-roasted root vegetables like carrots, parsnips, and sweet potatoes that echo the steak's caramelized exterior.
• Create Zesty Chimichurri Sauce: Whip up a bright, herbal Argentine-style sauce with fresh parsley, garlic, olive oil, and red wine vinegar to add tangy contrast to the meat's deep umami notes.
• Serve with Crisp Craft Beer: Choose a hoppy IPA or amber ale that stands up to the steak's robust character and provides a refreshing counterpoint to its richness.

Change It Up With Grilled London Broil

• Spicy Southwest Kick: Replace Dijon mustard with chipotle peppers in adobo sauce, add ground cumin and smoked paprika to marinade for a bold, southwestern flavor profile that brings heat and depth.
• Mediterranean Herb Infusion: Swap Worcestershire sauce with red wine, incorporate fresh rosemary, thyme, and oregano into the marinade, creating a bright, herbaceous Mediterranean-inspired version that elevates the steak's natural richness.
• Asian Fusion Blend: Modify marinade by adding sesame oil, grated ginger, rice vinegar, and a touch of honey, transforming the London broil into a savory Asian-inspired dish with complex umami undertones.
• Caribbean Rum Marinade: Introduce dark rum, allspice, and orange zest to the original marinade, developing a tropical-influenced preparation that adds subtle sweetness and Caribbean warmth to the grilled steak.

Grilled London Broil FAQ Roundup

• What makes London broil different from other beef cuts?

London broil isn’t actually a cut of meat, but a cooking method typically using top round or flank steak. These cuts are leaner and more muscular, requiring marinating and careful cooking to ensure tenderness.

• Why is marinating so crucial for London broil?

Marinating helps break down tough muscle fibers, adding flavor and making the meat more tender. The acidic ingredients like balsamic vinegar and lemon juice help soften the meat, while herbs and spices enhance its overall taste.

• How can I tell if my London broil is cooked perfectly?

Use a meat thermometer to check internal temperature. For medium-rare, aim for 130-135°F. Remember that the temperature will rise slightly while resting, so remove the steak just before it reaches your desired doneness.

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

Absolutely! Preheat your oven to 400°F and use a cast-iron skillet or broiler pan. Sear the steak on high heat for 2-3 minutes per side, then finish in the oven until it reaches your preferred internal temperature.

Instructions

1. Craft a vibrant marinade by whisking olive oil, soy sauce, balsamic vinegar, Worcestershire, lemon juice, minced garlic, brown sugar, Dijon mustard, black pepper, and onion powder in a medium mixing bowl until thoroughly combined.
2. Transfer the London broil into a large resealable plastic bag or shallow container, then completely submerge the meat in the prepared marinade. Seal and refrigerate for a minimum of 4 hours, allowing the flavors to deeply penetrate the protein.
3. Remove the marinated steak from the refrigerator approximately 30 minutes before grilling to ensure even temperature distribution. Meanwhile, prepare the grill to medium-high heat, targeting around 400-450°F.
4. Carefully place the London broil onto the preheated grill grates, cooking for 5-7 minutes on each side to achieve a perfect medium-rare doneness with an internal temperature of 130-135°F. Adjust cooking duration based on the cut’s thickness and personal preference.
5. Once grilled, transfer the steak to a cutting board and allow it to rest undisturbed for 10 minutes. This crucial resting period helps redistribute the meat’s juices, ensuring maximum tenderness and flavor.
6. Using a sharp knife, slice the London broil thinly against the grain to maximize tenderness. Arrange on a serving platter and optionally garnish with fresh parsley.
7. Complement the grilled steak with roasted seasonal vegetables, a crisp garden salad, or herb-infused potatoes for a complete and satisfying meal.
