If you’ve been searching for a steak recipe that delivers restaurant-quality results without the hefty price tag, this London Broil is about to become your new favorite. I’m talking about tender, juicy flank steak that’s perfectly seasoned and cooked to perfection every single time.

The simple yet powerful marinade that transforms an ordinary cut into something extraordinary.

What Ingredients are in Melt-in-Your-Mouth London Broil?

To make a perfect London Broil that’s tender and flavorful, you’ll need just a handful of simple ingredients. The magic happens in the marinade, which tenderizes the naturally lean flank steak and infuses it with a savory, bright flavor profile. This classic recipe keeps things straightforward but delivers impressive results that’ll make you look like a seasoned chef at your next dinner gathering.

When shopping for your flank steak, look for a piece with good marbling throughout, as this will contribute to a more tender final result. The oil can be whatever you have on hand—olive oil works beautifully, but vegetable or canola oil are perfectly fine substitutes. And while dried parsley can work in a pinch, fresh really makes a difference in the brightness of the marinade. You might also consider doubling the marinade ingredients if you prefer a more intensely flavored steak or if your cut is on the larger side. The simplicity of these ingredients makes this London Broil accessible for weeknight cooking, yet impressive enough for special occasions.

  • 1½-2 pounds flank steak
  • 1 tablespoon lemon juice
  • 1 tablespoon oil
  • 2 teaspoons chopped fresh parsley
  • 1 clove garlic, crushed
  • 1 teaspoon salt
  • ⅛ teaspoon pepper

Let’s start with the marinade, which is where all the flavor magic happens. In a small bowl, combine 1 tablespoon of lemon juice, 1 tablespoon of oil, 2 teaspoons of chopped parsley, 1 clove of crushed garlic, 1 teaspoon of salt, and 1/8 teaspoon of pepper. This simple mixture mightn’t look like much, but trust me, it’s going to transform your 1½-2 pounds of flank steak into something spectacular. Give it a good stir until everything is well incorporated.

Now for the patience part. Place your flank steak in a shallow dish where it can lie completely flat—no curling up the edges, please. Pour your marinade over the steak, making sure to coat both sides. Cover the dish and pop it in the refrigerator for at least 2 hours. Waiting is the hardest part, right? But this time allows those flavors to penetrate the meat, tenderizing it and infusing it with a zesty, garlicky goodness.

When you’re ready to cook, position your oven rack about 4 inches from the broiler and preheat. Place the marinated steak on a broiler pan and cook for about 15 minutes. Then flip it over, brush with any remaining marinade, and broil for another 5 minutes. For even better results, consider cooking your steak in a cast iron pan which provides excellent heat retention and distribution. The key to serving? Slice very thinly across the grain—this makes all the difference between a chewy disappointment and those melt-in-your-mouth slices we’re aiming for.

Melt-in-Your-Mouth London Broil Substitutions and Variations

While the classic London broil recipe delivers amazing results, you can jazz it up with numerous variations that’ll make this dish your own personal masterpiece.

Try swapping lemon juice for balsamic vinegar or soy sauce for deeper flavor. Not a fan of parsley? Rosemary or thyme work beautifully. You might even add a tablespoon of Dijon mustard to the marinade for tangy complexity.

For heat lovers, a dash of red pepper flakes or minced jalapeño transforms this dish entirely. Honestly, who doesn’t love a little kick?

The cut itself is flexible too. Can’t find flank steak? Top round makes a wonderful substitute, though you might need to adjust cooking time slightly. The magic is in slicing thin, across the grain, no matter which cut you choose.

What to Serve with Melt-in-Your-Mouth London Broil

Complementary sides transform your London broil from mere protein to a complete dining experience. I’m a firm believer that starchy sides like roasted potatoes or a creamy risotto provide the perfect canvas for those delicious meat juices.

Can’t you just imagine that tender, thinly sliced flank steak alongside a bright, acidic side like a tomato salad with balsamic glaze?

For a truly balanced plate, I’d recommend a vibrant vegetable option – perhaps asparagus or green beans quickly sautéed with garlic. They add color and freshness without overwhelming the star of the show. And don’t forget a simple sauce option, maybe a chimichurri or horseradish cream to complement those savory flavors. The trick is balance – something starchy, something fresh, and something with a bit of zing.

Final Thoughts

The joy of mastering a perfect London broil extends far beyond just the meal itself. It’s about creating those memorable dining experiences where conversation flows as smoothly as a good red wine alongside your perfectly sliced flank steak.

I’ve found that the key truly lies in patience—giving the meat time to marinate and rest properly makes all the difference between tough disappointment and tender delight.
