London Broil Marinade How To Cook London Broil

What is London Broil + Why We Love it

Almost 25 years ago, when Lieutenant Dan and I were newlyweds, we would cook certain meals to feel fancy on a small budget. Some of our heavy hitters included jambalaya, pain perdu, bread pudding, and of course, London Broil. London Broil is not actually a particular cut of meat… Rather, the name refers to the high-heat cooking technique used. The meat is typically a section of Top Round, which was a favorite of ours because it’s technically a steak, but usually cheaper than finer cuts of steak. When you broil and slice it, you can enjoy London Broil even on a newlywed budget. The key to making a fabulous Top Round Steak is to score it, marinate it, and broil it under high heat. Scoring the top and bottom allows the marinade flavors to soak deep into the beef. This London broil marinade combines salty, sweet, and spicy ingredients for a robust flavor that pairs well with anything! Broiling a London broil creates a crispy exterior and a tender medium-rare interior you’ll love.

London Broil Marinade Ingredients

London broil – cut from the Top Round (also known as top-round steak) Dijon mustard – a tangy and spicy mustard Light brown sugar – the mellow sweetness also helps to tenderize the meat Orange juice – adds flavor to the marinade, but the citrus taste is minimized once the steak is cooked Soy sauce – I suggest low-sodium soy sauce Fish sauce – funky and sweet, this sauce adds a great umami flavor (or Worcestershire sauce) Fresh ginger – peeled and grated Garlic – minced Crushed red pepper flakes – for a nice kick of heat, but entirely optional

Best Substitutes for London Broil

Most often what is called a London broil at the grocery store is, in fact, a cut of top round roast. But there are a few tasty cut of beef alternatives that work well with this delicious marinade! Flank steak, sirloin steak, skirt steak, and hanger steak have a similar taste and texture. Brisket is a bit tougher, but will still tenderize beautifully when marinated.

How to Marinate and Cook London Broil

Place the London Broil on a cutting board. Use a sharp knife to score the top and bottom of the London broil, cutting ¼ inch deep, in long strokes, across the surface, spacing the cuts about ¾ inch apart. Then turn the London broil and score again, in a perpendicular direction, to create a checkerboard pattern. Turn the London broil over and repeat on the other side. See photos for a reference. Next, make the marinade for the London broil. In a small mixing bowl, combine the Dijon mustard, brown sugar, orange juice, soy sauce, fish sauce, ginger, garlic, and crushed red pepper. Mix well to combine. Place the London broil in a rimmed baking dish, or a gallon zip bag. Pour the marinade over the top. If using a dish, cover the dish with plastic wrap and place it in the refrigerator. If using a plastic bag, squeeze the air out of the bag, and zip tightly. Shake the bag around, and place it in the refrigerator Marinate the London broil for at least 3 hours, but up to 24 hours. To cook the London broil, take the steak out of the marinade, and discard the remaining marinade. Use paper towels to dry off both flat surfaces of the meat. Preheat the broiler to 500°F. Move the top rack approximately 4 inches from the broiler. Set a large cast-iron skillet on the rack to preheat. Once hot, carefully place the London broil in the cast iron skillet. Broil for 4 minutes per side, flipping once, 8 minutes total. Remove from the oven and allow the steak to rest for at least 5 minutes. Then slice into thin strips, against the grain, and serve warm.

What to Serve with London Broil

Potatoes are an excellent choice to serve with meat, of course! Pair the steak with tender roasted potatoes, fluffy baked potatoes (you’ll love our foolproof microwave method), or hasselback potatoes for a cozy starch. Any veggie goes perfectly with a well-cooked steak. Keep things simple with a side of roasted or steamed broccoli, air fryer asparagus, green beans or brussels sprouts, or sautéed mushrooms. The vibrant sweet, spicy, and savory flavor of London Broil pairs well with Tex-Mex-style sauces. In the photos, we serve the steak with a rich avocado crema sauce and fresh sliced green onions. Or try other delicious toppings like chimichurri sauce, unbelievably flavorful cowboy butter, or a rich cognac cream sauce. Thin strips of broiled top round are also great to enjoy in sandwiches and wraps, on salads, or loaded into burritos or tacos! Or use them in any recipe that calls for cooked steak, like steak fajita stuffed avocados and roll ups.
