London Broil: A Timeless Classic for Every Budget

For many, London Broil evokes memories of special meals, often crafted with ingenuity on a modest budget. It’s a dish that feels undeniably fancy yet remains incredibly accessible, making it a beloved choice for home cooks seeking impressive results without breaking the bank. My husband and I, in our newlywed days, frequently turned to recipes like jambalaya, pain perdu, bread pudding, and of course, London Broil, to create memorable dining experiences.

It’s important to clarify a common misconception: London Broil is not a specific cut of meat, but rather a cooking method. Historically, the term refers to a technique involving high-heat cooking, typically broiling, followed by thinly slicing the meat against the grain. The cut most commonly labeled and used for London Broil in grocery stores is a section of Top Round. This particular cut is lean and flavorful, offering a steak-like experience that is generally more economical than premium steak cuts. When properly prepared with marinating and broiling, Top Round transforms into wonderfully tender London Broil, making it a fantastic option even for those on a tight budget.

Achieving Ultimate Tenderness: The Key to Perfect London Broil

The secret to transforming a lean cut like Top Round into a truly fabulous London Broil lies in three critical steps: scoring, marinating, and broiling at high heat. Scoring the meat, by making shallow cuts across its surface, serves multiple essential purposes. Firstly, it creates channels that allow the rich flavors of our savory marinade to penetrate deep into the beef, infusing every bite with deliciousness. Secondly, these cuts help the high heat to cook the meat more evenly, preventing toughness. Lastly, scoring contributes to the desired texture – a wonderfully crispy exterior complemented by a tender, medium-rare interior. This simple yet effective preparation method guarantees a London Broil you’ll be eager to make again and again.

Our carefully crafted London Broil marinade is the heart of this recipe. It masterfully blends salty, sweet, and subtly spicy elements to create a robust and complex flavor profile that beautifully enhances the beef. This versatile marinade not only tenderizes the meat but also ensures it pairs exquisitely with a wide array of side dishes and sauces.

Broiling the London Broil under high heat is the final touch, creating that irresistible crispy crust while locking in the juices for a perfectly tender, medium-rare finish. It’s a cooking technique that delivers maximum flavor and an ideal texture, making your homemade London Broil rival any steakhouse offering.

Essential Ingredients for Our London Broil Marinade

A truly exceptional marinade is what elevates London Broil from a simple cut of beef to a show-stopping meal. Each ingredient in our recipe plays a crucial role, contributing to both the flavor and the tenderization of the meat. Here’s a closer look at what you’ll need:

  • London Broil (Top Round Steak): The star of our dish. This lean cut, often labeled as top round roast or steak, benefits immensely from proper marinating and high-heat cooking.
  • Dijon Mustard: Adds a sophisticated tang and a slight peppery kick. Dijon also acts as an emulsifier, helping to bind the marinade ingredients together for a consistent flavor distribution.
  • Light Brown Sugar: Provides a mellow sweetness that balances the savory and tangy components. More importantly, sugar aids in tenderization and promotes beautiful caramelization on the meat’s surface during broiling, creating that desirable crust.
  • Orange Juice: Beyond adding a subtle citrus flavor, the acidity in orange juice is key to breaking down tough meat fibers, contributing significantly to the London Broil’s tenderness without imparting an overpowering orange taste once cooked.
  • Soy Sauce: A cornerstone for umami depth and salinity. We recommend using low-sodium soy sauce to control the overall saltiness. Coconut aminos make an excellent gluten-free alternative.
  • Fish Sauce: Don’t let the name deter you! Fish sauce (or Worcestershire sauce as a substitute) is a powerhouse of savory, umami flavor. It adds an incredible depth and complexity that will make your London Broil truly unforgettable.
  • Fresh Ginger (Peeled and Grated): Delivers a warm, pungent, and aromatic zest that brightens the entire marinade. Freshly grated ginger offers the best flavor.
  • Garlic (Minced): Indispensable for its robust, aromatic base. Garlic pairs perfectly with beef and complements all the other marinade ingredients.
  • Crushed Red Pepper Flakes: Optional, but highly recommended for those who enjoy a little kick of heat. Adjust the amount to your preference or omit entirely for a milder profile.

Choosing the Right Cut: Versatile Alternatives for London Broil

While “London Broil” typically refers to Top Round, this fantastic marinade is incredibly versatile and works wonders with several other beef cuts that share similar characteristics. If Top Round isn’t available or you simply want to try something new, these alternatives will yield delicious results:

  • Flank Steak: A lean, flavorful cut with distinct grain, making it an excellent candidate for marinating and quick cooking. It’s perfect for slicing against the grain.
  • Sirloin Steak: A widely available and moderately tender cut, sirloin takes well to marinades and high-heat cooking.
  • Skirt Steak: Known for its rich beefy flavor and loose texture, skirt steak absorbs marinades beautifully and cooks quickly. Like flank, it requires slicing against the grain for tenderness.
  • Bavette Steak (Flap Meat): Similar to flank and skirt, bavette is lean, intensely flavorful, and benefits greatly from marinating. It’s a favorite among chefs for its texture.
  • Hanger Steak: Often called the “butcher’s steak,” hanger steak is prized for its tenderness and deep, rich beef flavor, especially when marinated and cooked quickly.
  • Brisket (Flat Cut): While traditionally a slow-cook cut, the flat cut of brisket can be surprisingly tenderized by this marinade, resulting in a flavorful, albeit slightly firmer, London Broil experience.

The Art of London Broil: Marinating and High-Heat Perfection

Creating truly tender and flavorful London Broil is a straightforward process when you follow a few key techniques. The journey begins with preparing the meat for maximum flavor absorption and even cooking.

Tips for Success: The first crucial step is to score your London Broil. Using a sharp knife, make shallow cuts approximately ¼ inch deep across the top and bottom surfaces of the meat. These cuts should be long strokes, spaced about ¾ inch apart. After completing the first set of cuts, turn the meat and score again in a perpendicular direction, creating a distinctive checkerboard pattern. This scoring technique offers a trifecta of benefits: A) It dramatically increases the surface area, allowing the marinade to penetrate deeper into the beef, infusing it with richer flavor. B) It helps the intense heat from the broiler to cook the beef more uniformly, preventing some parts from overcooking while others remain undercooked. C) It enhances the overall texture, contributing to that highly desirable crispy-on-the-outside, tender-in-the-middle contrast that defines a perfectly cooked London Broil.

Perfect Pairings: What to Serve with London Broil

Once you’ve mastered the art of tender and juicy London Broil, the next step is deciding on the perfect accompaniments. This versatile steak pairs beautifully with a wide variety of side dishes, from hearty starches to fresh vegetables and decadent sauces.

Hearty Starches: Potatoes are, without a doubt, a classic and excellent choice to serve alongside any beef dish. Consider serving your succulent London Broil with tender crispy roasted potatoes, light and fluffy baked potatoes (our foolproof microwave method is a game-changer!), creamy mashed potatoes, or elegant hasselback potatoes for a comforting and satisfying meal.

Fresh and Flavorful Vegetables: Any fresh vegetable will complement a perfectly cooked steak. Keep it simple yet delicious with a side of perfectly roasted broccoli or quick steamed broccoli. Alternatively, whip up some vibrant air fryer asparagus, crisp air fryer green beans, flavorful air fryer Brussels sprouts, or rich sautéed mushrooms for a fresh and nutritious addition.

Delectable Sauces and Toppings: The sweet, spicy, and savory notes of our London Broil marinade harmonize exceptionally well with creamy, zesty, or rich sauces. As seen in our photos, a vibrant avocado crema sauce and fresh sliced green onions provide a bright contrast. Other delicious toppings include a zesty creamy chimichurri sauce, unbelievably flavorful cowboy butter, or a luxurious cognac cream sauce for a truly indulgent experience.

Beyond the Plate: Creative Uses for London Broil: Thin strips of broiled top round are also incredibly versatile for other meals. Enjoy them in savory sandwiches and wraps, atop fresh salads, or loaded into burritos and tacos. They can also be used in any recipe that calls for cooked steak, such as steak fajita roll-ups, adding a gourmet touch to your weekly meal prep.

Frequently Asked Questions About London Broil

Is it possible to cook London Broil without marinating?

While you can technically broil a steak without marinating, it’s highly recommended for lean cuts like top round or flank steak, which are typically used for London Broil. Without a marinade, these cuts can be quite tough and chewy. Our marinade contains a strategic blend of acids (like orange juice), sugars, and salts, which work together to break down the protein fibers in the meat. This process, known as tenderization, significantly improves the texture and makes the steak much more enjoyable to eat. For the best results – tender, juicy, and flavorful – don’t skip the marinade!

Is marinating London Broil for 48 hours too long?

Yes, marinating London Broil for 48 hours is generally too long. For optimal tenderization and flavor infusion, we recommend marinating steak for a minimum of 3 hours and a maximum of 24 hours. Within this window, the marinade has enough time to work its magic, breaking down the meat fibers and imparting its delicious flavors without compromising the texture. Marinating for longer than 24 hours, especially with acid-based marinades, runs the risk of “over-tenderizing” the meat, causing it to become mushy or mealy. Stick to the 3 to 24-hour range for perfect results.

How long do London Broil leftovers last?

Properly stored London Broil leftovers can be enjoyed for several days. Once the cooked steak has cooled completely, wrap it tightly in plastic wrap or transfer it to an airtight container. It will keep fresh in the refrigerator for up to 3 days. For longer storage, London Broil freezes exceptionally well. After cooling, wrap the leftovers tightly in plastic wrap, then add an additional layer of aluminum foil for extra protection against freezer burn. Alternatively, place it in a freezer-safe airtight container or plastic zipper bag. Frozen London Broil can be stored for up to 3 months. To enjoy, simply thaw overnight in the refrigerator before reheating.

Can I add fresh herbs to the marinade?

Absolutely! Customizing your marinade with fresh herbs is a fantastic way to introduce new dimensions of flavor. If you’re looking for an alternative to or an addition to the ginger, fresh herbs like rosemary, thyme, oregano, and chives would all be excellent choices. Finely chop them and add them along with the other marinade ingredients. A little lemon zest can also be a delightful addition, adding a bright, fragrant note that complements the richness of the beef beautifully. Feel free to experiment and find your favorite combination!

Ingredients

US Customary – Metric
  • 2 – 2 ½ pounds London broil (Top Round Steak)
  • 3 tablespoons Dijon mustard
  • 3 tablespoons light brown sugar
  • 3 tablespoons orange juice
  • 2 tablespoons soy sauce (low-sodium recommended)
  • 2 tablespoons fish sauce (or Worcestershire sauce)
  • 2 tablespoons grated fresh ginger
  • 5-6 cloves garlic, minced
  • ½ teaspoon crushed red pepper flakes (optional)

Instructions

  1. Place the London Broil on a sturdy cutting board. Using a sharp knife, score both the top and bottom surfaces of the meat. Make cuts approximately ¼ inch deep, in long strokes across the surface, spacing the cuts about ¾ inch apart. Then, rotate the London Broil and score again in a perpendicular direction to create a distinct checkerboard pattern. Flip the meat over and repeat the scoring process on the other side. Refer to the photos provided for a visual guide.
  2. In a small mixing bowl, combine the Dijon mustard, light brown sugar, orange juice, soy sauce, fish sauce, grated fresh ginger, minced garlic, and crushed red pepper flakes (if using). Whisk all ingredients together thoroughly until well combined.
  3. Carefully place the scored London Broil into a rimmed baking dish or a gallon-sized zip-top bag. Pour the prepared marinade evenly over the meat, ensuring both sides are well coated. If using a dish, cover it tightly with plastic wrap before refrigerating. If using a plastic bag, press out as much air as possible, seal tightly, then gently massage the bag to distribute the marinade. Place in the refrigerator.
  4. Allow the London Broil to marinate for a minimum of 3 hours, but ideally for 6-12 hours, and no longer than 24 hours. This duration is crucial for both tenderization and flavor infusion.
  5. When ready to cook, remove the London Broil from the marinade and discard any remaining marinade. Pat both flat surfaces of the London Broil thoroughly dry with paper towels. A dry surface is essential for achieving a good sear.
  6. Preheat your oven’s broiler to 500°F (260°C). Position the top oven rack approximately 4 inches from the broiler heating element. Place a large cast-iron skillet (or another heavy, oven-safe pan) on this rack to preheat along with the broiler. Getting the pan scorching hot is key for a great crust.
  7. Once the skillet is smoking hot, carefully place the dried London Broil directly into the preheated cast-iron skillet. Broil for exactly 4 minutes per side. Flip the steak once halfway through, resulting in a total broiling time of 8 minutes for a perfect medium-rare. Adjust cooking time slightly for desired doneness, but be mindful of lean cuts.
  8. Remove the London Broil from the oven and transfer it to a clean cutting board. Allow the steak to rest for at least 5 to 10 minutes. Resting is vital; it allows the juices to redistribute throughout the meat, ensuring a tender and moist final product. After resting, slice the London Broil into thin strips, always cutting against the grain, and serve warm with your chosen sides.

Notes

To store leftovers, ensure the cooked London Broil has cooled completely before transferring it to an airtight container. It will keep fresh in the refrigerator for up to 3 days. For longer storage, wrap cooled leftovers tightly in plastic wrap or place them in a freezer-safe airtight container, such as a plastic zipper bag. For added protection against freezer burn, you can then wrap it in an additional layer of aluminum foil. Freeze for up to 3 months and thaw overnight in the refrigerator before reheating.
