Growing up, my mom often made London Broil. We viewed it as a fancy dinner because the flavors were so impressive.
But there is nothing fancy about London Broil. It is made with simple ingredients and an inexpensive cut of beef. And when prepared correctly, the results are spectacular.
What is London Broil?
Even though you may find cuts of beef labeled as London Broil, London Broil is not actually a cut of beef, but instead, it refers to the preparation. It is typically a top round steak or flank steak that is marinated and then broiled in the oven.
The combination of marinating and broiling at high heat results in a tender, succulent piece of beef from a tougher cut of beef.
Notes on Ingredients
- London Broil: When shopping for the beef for this recipe, you can select a cut of beef that is labeled as a London Broil, Top Round Steak, or Flank Steak.
- Pineapple Juice: Using 100% pineapple juice in the marinade for London Broil, not only helps to add flavor to the beef but will help to tenderize the tougher cut of meat.
- Red Pepper Flakes: The spice from the red pepper flakes adds a bit of kick to the marinade. Feel free to omit for sensitve palates or increase for a bit more heat.
How to Marinate London Broil
This cut of beef is desperate for flavor. My recipe for London Broil Marinade is made with simple ingredients that pack a ton of flavor into the beef while working to tenderize the beef.
You want to marinade the beef for at least 2 hours, but 8-12 hours is best. For best results, don't marinate longer than 24 hours, as the meat can begin to break down and become mushy.
- In a medium bowl whisk together the pineapple juice, oil, soy sauce, Worcestershire sauce, red pepper flakes, and dried minced onion together.
- Place the meat into a large storage bag or large dish and pour the marinade over the beef.
- Seal the bag and toss to coat. If using a bowl, try to fully submerge the beef in the marinade.
- Place into the refrigerator and allow the meat to sit in the marinade for at least 2 hours or overnight, but no longer than 24 hours.
How to Cook London Broil
- When ready to prepare, preheat the broiler on your oven to high heat and adjust an oven rack to be about 4-5 inches from the flame.
- Remove the beef from the marinade, letting the excess marinade drip away, and place it onto a sheet pan. Discard the marinade.
- Place the sheet pan into the preheated oven and broil for 5 minutes. Remove from the oven and flip the meat and return to the oven and broil for 3-4 minutes, or until the internal temperature reaches 130 degrees Fahrenheit.
- Remove the meat from the oven and allow to rest for 10 minutes. This will allow the London Broil to reach about 135 degrees in temperature AND redistribute the juices through the beef, keeping it flavorful and juicy once cut.
- To serve, cut the London Broil against the grain into very thin slices.
Storing Leftover London Broil
London Broil is best served immediately. However, leftover London Broil can be stored in a sealed container for 3 days.
If the leftovers are cut into slices already, reheat the slices in a dry skillet quickly until just warm. If the London Broil is not sliced, broil for 2 minutes per side just to warm through.
I find that leftover London Broil is best when used in the filling of quesadillas, fajitas, tacos, as a filling for a quick steak sandwich, or for topping on a salad instead of being served alone.
Recipe FAQs
Yes, you can certainly grill your marinated cut of beef. Preheat your grill to medium-high. Remove the meat from the marinade and then grill for 7-8 minutes per side, or until the internal temperature reaches 130-135 degrees.
London Broil is best served medium-rare, which is between 130-135 degrees Fahrenheit. While you can cook to medium or medium-well, the meat will not be as tender or juicy.
If you look at the London Broil, there are parallel lines of muscle fiber running down the meat. You want to cut in the opposite direction, or perpendicular, to those parallel lines. This results in tender, melt-in-your-mouth steak.
Yes! Feel free to use any of your favorite marinades in place of this pineapple soy marinade. Just be sure that you don't marinate the beef for longer than 2 hours if the marinade is made with lemon or lime juice, as the acid will break the beef down too much if marinated past 2 hours.
No, but by inserting an oven-safe thermometer into the middle of the London Broil, you can ensure that the beef reaches the correct temperature. You can remove your London Broil and check the temperature every 3 minutes using a digital thermometer if it is not oven-safe. Food and Wine has a good guide to follow to determine the temperature of the beef without a thermometer.

I don't have pineapple juice in the house. Can I use orange juice for the marinade?
Kristen Chidsey
Yes! It will have a more citrus-y flavor, but should be delicious.
