What is London Broil?
London Broil refers to both a technique for cooking beef, and a specific cut of meat. Top-round steak and flank steak are the most common cuts sold under this name because they marinate well.
The technique involves marinating, grilling, and thinly slicing beef. This makes it a perfect choice for turning an affordable steak into a tender, restaurant-quality meal.
Grilled London Broil Ingredients

- balsamic vinegar
- soy sauce
- Worcestershire sauce
- olive oil
- lemon juice freshly squeezed
- garlic powder
- brown sugar
- powdered ginger

- fresh parsley (optional)
How to Cook London Broil
- Whisk together soy sauce, balsamic vinegar, powdered ginger, Worcestershire sauce, olive oil, fresh lemon juice, garlic powder, brown sugar, and red pepper flakes to create the London Broil marinade.
- Pour the marinade into a zip-lock bag, then add London Broil steak. Shake well and refrigerate to marinate for at least 4 hours up to overnight.
- Remove the steak from the bag and set it aside. Keep the marinade! You will use it later to make a sauce. Season steak with salt and pepper to taste on both sides.
- Add to the grill at 400°F for 5 to 8 minutes on each side. High heat works well for this recipe. Use a meat thermometer for best results.
- Meanwhile, pour steak marinade from the bag into a skillet over medium heat on the stove. Mix and let it simmer and thicken until it forms a sauce.
- Remove your steak from the grill, cover it with aluminum foil, and let it rest for 10-15 minutes. After resting, slice thinly and serve with sauce on top.

London Broil Recipe FAQs
The secret is in the marinade, grilling it properly, and slicing it thinly.By allowing your beef to marinate 4 hours up to overnight, it will soak in all of the delicious flavors of your marinade and be tenderized by the juices.
Then you take the marinade and turn it into a delicious garlic ginger sauce. It couldn’t be any tastier. Grilling it cooks it to the perfect temperature while giving it the perfect sear, and slicing it thinly against the grain ensures each bite is so tender.Cook your cut of beef at about 400°F (medium-high) on the grill for 5 to 8 minutes on each side.
This way you will achieve a perfect sear on your grilled London Broil while cooking it to a beautiful medium-rare on the inside.

Really good marinade and sauce afterwards. Unfortunately the cut of meat I used didn’t get very tender from the overnight marinade but I’ll try again.

Pat D. says
This marinade is delicious! I marinated the London Broil over night. The only thing I added was a sprig of fresh rosemary. Our card club devoured it!
