My recipe for London Broil marinade will help to ensure you ALWAYS have perfect results. Made with inexpensive ingredients, the marinade is sweet, savory, and helps to tenderize the beef. Once marinated, the London Broil is broiled (or grilled) to result in tender, succulent beef.
This marinated London Broil is one of the easiest recipes to make, yet the flavors are nothing short or spectacular. Pair it with rice pilaf and a bacon spinach salad for a meal with serious wow factor.
What You Need to Make London Broil
- Beef: London Broil is classically made with a top round steak or flank steak. Occasionally, you will find beef labeled as London Broil, but keep in mind, London Broil is not technically a cut of beef, but instead refers to the preparation of a cut of beef.
- London Broil Marinade: The marinade with made with garlic, Worcestershire, soy sauce, olive oil, red pepper flakes, dried onion, and pineapple juice. Using 100% pineapple juice in the London Broil marinade not only helps to add a subtle sweetness to the marinade, but helps to tenderize the tough cut of beef.
London Broil Marinade
The cut of beef used to make London Broil, is desperate for flavor and needs to be tenderized. This simple sweet and savory marinade recipes ensures the beef is both tenderized and infused with flavor.
Once the ingredients for the London Broil Marinade are whisked together, pour the marinade over the beef. I prefer placing both the beef and marinade in a large storage bag, which makes for easy clean up and makes it easier to toss the beef in the marinade.
How Long Does a London Broil Need Marinated?
You want to marinate the cut of beef for at least 2 hours, but 8-12 hours is best. Don’t marinate longer than 24 hours, as the meat can begin to break down and become mushy.
Broil London Broil
As the name suggests, this recipe is typically broiled, although, I have provided instructions for grilling London Broil in the recipe card if desired.
Regardless of whether or not you broil or grill the marinaded beef, it is critical to NOT overcook to ensure the London Broil is super tender. London Broil is best cooked until it reaches an internal temperature of 130-135 degrees F, which is medium-rare. I recommend inserting an oven-safe thermometer into the middle of the London Broil before placing it under the broiler or on the grill, which will ensure that the beef reaches the correct temperature.
Cut London Broil Against the Grain
Another tip to keeping your beef super tender and juicy is to let it rest for 10 minutes after it has been cooked. Once rested, cut the London Broil against the grain into very thin slices, which just means to cut in the opposite direction, or perpendicular, to the parallel lines running down the meat.
Serving Suggestions
London Broil makes an impressive beef entree but can also be served in salads or in rice bowls if desired.
London Broil Variations
- Make it Sweeter: While the pineapple juice sweetens the marinade naturally, feel free to add up to 2 tablespoons of honey or maple syrup to the marinade for a sweeter spin with rich caramel notes.
- Control the Spice: Control the heat by omitting or decreasing the amount of crushed red pepper flakes in the marinade. You can also add up to 2 teaspoons of hot sauce for additional heat.
- No Dried Onion Flakes? Use 2 teaspoons of onion powder instead.
- Add Fresh Herbs: Feel free to add sprigs of thyme or rosemary to the marinade if desired.
Storage & Reheating Instructions
- Refrigerate: London Broil is best served immediately. However, leftover London Broil can be stored in an airtight sealed container for 3 days in the refrigerator.
- Reheat: 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.
- Suggestions for Leftovers: I find that leftover London Broil is best when added to a cheese quesadilla or veggie fajitas, or used to make a quick taco or steak sandwich.

Instructions
-
For the London Broil Marinade, whisk together the pineapple juice, soy sauce, Worcestershire sauce, garlic, red pepper flakes, dried minced onion, and olive oil.
-
Place the meat into a large storage bag or bowl and pour the marinade over the meat. Toss the meat in the marinade to coat and distribute the marinade evenly over the meat. Marinate the beef in the refrigerator for at least 2 hours and up to 24 hours. I find 8-12 hours best.
-
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 meat from the marinade and place it onto a sheet pan and discard the marinade.
-
Place the sheet pan into the 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 an internal temperature of 130℉ to 132℉ for medium-rare.
-
Remove the meat from the oven and allow to rest for 10 minutes–it will rise in temperature to about 135 degrees.
-
After resting the London Broil, cut the beef against the grain (perpendicular to the parallel lines of muscle fiber running down the meat) into very thin slices. and serve immediately.
Notes
Temperature of the Meat: London Broil is best served medium-rare, which is an internal temperature of 130-135 degrees. This is best determined by inserting an oven-safe digital thermometer into the center of the steak and monitoring the temperature. Cook to 140-145 degrees for medium doneness, 150-155 for medium-well, or 160-165 degrees for well done.
Leftover London Broil can be stored in a sealed container for 3 days. Reheat slices in a dry skillet quickly until just warm, or broil unsliced London Broil for 2 minutes per side just to warm through.
Grill London Broil: 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. Remove from grill, rest for 10 minutes, cut, and serve.
