Pioneer Woman London Broil Recipe: Marinated Grill Masterpiece

This London broil recipe transforms an affordable cut into a tender, flavorful masterpiece with a simple marinade and hot grill. The key lies in proper slicing against the grain, which ensures each bite melts in your mouth.

I’ve perfected this method over years of backyard cookouts, discovering that a 2-hour marinade in soy sauce, garlic, and brown sugar creates depth without overpowering the beef’s natural richness.

The result is a juicy, caramelized steak with a smoky char from the grill. It’s impressive enough for guests but easy enough for a weeknight dinner.

Serve it thinly sliced with roasted potatoes or a fresh salad for a complete meal that feels like a steakhouse experience at home.

Ingredients for Pioneer Woman London Broil

Eleven ingredients build a marinated steakhouse experience right in your backyard grill.

The steak selection is critical here. Top round or flank are traditional choices for London broil, offering robust beefy flavor at an affordable price point. Look for cuts with visible marbling (about 1-1.5 inches thick) from Costco or your butcher—avoid pre-cut steaks that are too thin. The soy sauce forms the backbone of the marinade; Kikkoman low-sodium provides consistent quality without overwhelming saltiness.

No Worcestershire sauce? Substitute with additional soy sauce and a dash of balsamic vinegar. Dried thyme can be replaced with fresh rosemary at half the quantity. For a sweeter profile, swap brown sugar for maple syrup or honey. Apple cider vinegar can be replaced with red wine vinegar in a pinch. The Dijon mustard is non-negotiable though—it emulsifies the marinade beautifully.

Marinate the steak for 2-12 hours in the refrigerator for optimal flavor penetration. Leftovers keep well for 3-4 days when stored airtight. Slice against the grain just before serving to maintain tenderness. The marinade can be made 2 days ahead and stored separately.

Step-by-Step Instructions for Marinated London Broil

Master this technique for a perfectly tender, flavorful steak with a caramelized crust.

Step 1: Prepare the Marinade Base

In a medium bowl, whisk together the 0.5 cup Soy Sauce, 0.25 cup Brown Sugar, and 0.25 cup Olive Oil until the sugar begins to dissolve. The oil and soy sauce will separate initially—that’s normal. This emulsified base forms the flavor foundation for the entire dish.

Add the 2 tbsp Apple Cider Vinegar, 2 tbsp Worcestershire Sauce, and 1 tbsp Dijon Mustard. Whisk vigorously for 1-2 minutes until the mixture thickens slightly and becomes uniform. The vinegar and Worcestershire balance the sugar’s sweetness while the mustard adds body to the marinade.

Step 2: Incorporate Aromatics and Seasonings

Mince the 5 cloves Garlic Cloves finely—this ensures even distribution throughout the marinade. Add the minced garlic to the bowl along with the 1 tsp Black Pepper, 1 tsp Kosher Salt, 0.5 tsp Dried Thyme, and 0.5 tsp Red Pepper Flakes.

Crush the thyme between your fingers as you add it to release its essential oils. Stir all ingredients together until fully combined. The garlic infuses the marinade with pungent depth, while the spices create a complex, well-rounded flavor profile that penetrates the meat.

Step 3: Marinate the London Broil

Place the 2 lb London Broil Steak in a shallow dish or resealable plastic bag. Pour the marinade over the steak, ensuring it’s fully submerged. Turn the steak to coat all sides evenly. This step guarantees every bite absorbs maximum flavor.

Seal or cover and refrigerate for at least 4 hours, or ideally overnight. The longer marinating time allows the acidic components to tenderize the meat while the salt and sugars work their way deep into the fibers. For best results, flip the steak halfway through the marinating period.

Step 4: Grill to Medium-Rare Perfection

Preheat your grill to high heat (about 450°F). Remove the steak from the marinade, allowing excess to drip off, and place it on the grill. Sear for 4-5 minutes per side with the lid closed, resisting the urge to flip early. The steak will release naturally when it’s ready to turn.

Look for a deep, caramelized crust and internal temperature of 130-135°F for medium-rare. The sugars in the marinade create a beautiful char, while the high heat seals in juices. If flare-ups occur, move the steak to a cooler part of the grill temporarily.

Step 5: Rest and Slice Against the Grain

Transfer the steak to a cutting board and tent loosely with foil. Let it rest for 10-15 minutes—this critical step allows the juices to redistribute throughout the meat. Skipping this will result in a dry steak with all the flavorful juices pooled on your cutting board.

Slice thinly against the grain, which shortens the muscle fibers and ensures tenderness. The grain in London Broil runs lengthwise along the steak, so cut perpendicular to those lines. Serve immediately while warm, with any reserved marinade boiled for 3-5 minutes as a sauce if desired.

Wine and Beer Pairings for These Flavors

Bold Red Wines

For this dish, a full-bodied Cabernet Sauvignon from Napa Valley cuts through the richness with its dark fruit and tannic structure. I love Josh Cellars for its approachable price and consistent quality. Serve slightly below room temperature for best balance. 🍷

Smooth Malbec

An Argentine Malbec like Catena offers plush blackberry flavors and velvety texture that complements the steak’s char. The wine’s smoky notes echo the grill’s caramelization beautifully. Chill for 20 minutes before serving to enhance its complexity.

Craft Beer Options

A robust porter or stout beer provides a delightful contrast with its roasted malt flavors. I recommend Guinness or Founders Porter—their coffee and chocolate notes pair wonderfully with the soy-marinated beef. Serve at 45-50°F for optimal taste.

Lighter Alternatives

If you prefer white wine, a bold Chardonnay with oak aging can work surprisingly well. Look for California options like Kendall-Jackson with its buttery finish. The acidity helps cut through the dish’s richness while the oak complements the caramelized crust.

Non-Alcoholic Pairings

For non-drinkers, a sparkling black cherry soda or iced hibiscus tea offers refreshing contrast. The tartness in both balances the steak’s savory depth. I particularly enjoy San Pellegrino Aranciata for its citrusy brightness.
