It sounds like the fanciest entrée at the best restaurant in town, but actually Grilled London Broil is an inexpensive and delicious way to feed a large family or a backyard full of hungry guests. The marinade does most of the work for you and the coals do the rest for perfect results every time.
This classic recipe for Grilled London Broil relies on an herb and balsamic marinade that works its magic for up to eight hours in the refrigerator.

What is London Broil?
Despite its name, London Broil is a way to cook a marinated cut of meat, using a broiler or hot grill, that originated in America. Once it’s marinated for several hours, the meat is cooked quickly and sliced thin to serve.
What cut of meat is London Broil?
Typically, if you ask for London Broil, butchers will give you top round steak, top blade steak, or flank steak. Top round steak is an incredible value as a cut, because it is less desirable than filet or other more expensive steaks.
Here, we score the surface of the meat for extra tenderness and then marinate it into submission.
Can you broil London Broil?
Don’t let the weather stop you from making this! Go ahead and broil it, instead of lighting those coals. Adjust your broiler rack to about 6 inches below the broiler. Place meat on a foil-lined pan. Turn every 2 minutes, for even cooking, about four times, until done.
How is London Broil different from flank steak?
Because London Broil is the name of a finished dish, it’s possible that you’ve had London broil that was made with flank steak.
How do you cut London Broil?
This juicy, mouthwatering dish gets cut into thin slices, against the grain
What is the best temperature for Grilled London Broil?
Because the meat used to make London Broil is lean, the best way to eat it is to cook it medium rare. Of course, if your family likes to eat steak on the well done side of the dial, cook it a little longer. Just know that some tenderness may be sacrificed in the end product, but it will still be delicious.
Can you make London Broil marinade without ketchup?
Ketchup provides a little sweetness in the marinade, but feel free to use tomato paste or even a spoonful of dijon mustard instead.
What do you do with leftover London Broil?
You can do almost anything with the leftovers, if there are any, but I always love to make sandwiches or toss slices of the meat in with a big green salad.
