Fire up the BBQ! Because this recipe for London Broil Marinade is going to blow your mind! This marinade produces tender, juicy, and tasty grilled beef that can be used in sandwiches, on top of salads, or simply eaten as a main dish with a few sides.
London Broil, also referred to as Top Round, or Coulotte, can be an intimidating cut of meat for some who are not familiar with it. However, it’s actually quite easy to prepare. It’s a very lean cut of meat, so marinating it before you cook it is ideal, as the marinade helps to tenderize it.
How to tenderize London broil:
While using a marinade aids in the tenderizing process, to further tenderize the London broil, I use the flat side of a meat tenderizer to evenly pound both sides of the meat. This breaks down the connective tissues, producing a softer piece of meat once it’s grilled. Just remember, think tenderize – not pulverize. And you want to pound the meat evenly. If the meat is cut unevenly, pound it out to one thickness to ensure even cooking.
How to make Grilled London Broil Marinade:
This homemade gluten-free garlicky marinade can be easily thrown together with ingredients you most likely already have in your pantry.
- Balsamic Vinegar– This is dark vinegar is intense in flavor and slightly sweet. The sweetness aids in the browning reaction as the London broil is grilled, and significantly enhances the flavor of the outer layer of the meat.
- Braggs Liquid Aminos or Gluten-Free Soy Sauce (tamari)- I use Braggs Liquid Aminos in this marinade recipe, but if you prefer tamari, feel free to use that instead. Both Braggs Liquid Aminos and gluten-free soy sauce are wonderful for imparting a salty/umami type flavor everyone loves. That’s what makes it perfectly suited for marinade recipes.
- Olive Oil– Olive oil helps lock moisture in and reduces moisture loss during the cooking process. It also prevents your meat from sticking to the grill. I normally use olive oil because it’s what I have on hand, but you could also use avocado oil or another light tasting oil.
- Gluten-Free Worcestershire Sauce– Worcestershire sauce is a fermented liquid condiment mostly used to enhance flavor. It, combined with the other ingredients in this quick London broil marinade, packs a flavor punch!
- Minced Garlic– My family LOVES garlic. If you like a little less, or a little more, feel free to adjust it to your preference.
- Dried Italian Seasoning– Dried Italian seasoning adds another depth of flavor to the marinade. If you need a substitute, try dried basil, or just omit it altogether. The marinade will still taste amazing!
- Ground Black Pepper– Ground black pepper imparts a spicy bite to the marinade. I keep the amount fairly tame because of my younger daughter with the sensitive-to-spice palate. You can easily increase the amount to 1 teaspoon if you’re looking to add more of a kick!
The best way to cook a London broil? Grill it.
HOW TO GRILL LONDON BROIL:
- Make sure you remove the marinated London broil from the refrigerator at least 45 minutes prior to starting your grill. It needs time to come up to room temperature.
- Preheat the grill to 400 degrees (F).
- Discard the marinade, and grill the London broil for 9-11 minutes on each side, or until the meat registers the preferred desired temperature: 125 F – rare, 135 F – medium rare, 145 F – medium, 150 F – medium well, 160 F – well done.
- Place the meat in a heat safe dish, and allow it to rest for at least 10 minutes.
- Slice against the grain, and serve immediately.
What to serve with this London Broil Recipe:
My personal favorites are Gluten-Free Pasta Salad, or Oven Roasted Horseradish Dijon Potatoes, but, if you’re looking for something different, try this Raw Beet, Carrot and Apple Salad (the ginger lime dressing is ahhhhhhh-mazing!).
Helpful information for those who love to camp:
For camping, I like to Foodsaver the London broil in the marinade, that way I can easily pull it out of the cooler when I get to my destination and throw it on the grill. The Foodsaver bags are so much stronger than plastic sealable bags; they have an airtight seal and really do ensure a mess-free cooler!
You can also freeze the Foodsavered package before packing it in the cooler. That way it will help keep all of the other cooler contents cold, and will take another day or two to thaw. I do this when we’re going on longer trips. It’s very handy!

London Broil Marinade Recipe
- 2 lbs London Broil
- ¼ cup balsamic vinegar
- ¼ cup Braggs Liquid Aminos or Gluten-Free soy sauce (tamari)
- ¼ cup olive oil
- 2 tablespoons gluten-free Worcestershire sauce
- 4-5 garlic cloves, minced
- 1 ½ teaspoon dried Italian seasoning
- ½ teaspoon ground black pepper
- Seal the uncooked London broil in a gallon-sized sealable plastic bag and place it on top of a large cutting board.
- Use the flat side of a meat tenderizer to pound both sides of the London broil evenly. This breaks down the connective tissues, producing a softer piece of meat once it's grilled. Just remember, think tenderize - not pulverize. And you want to pound the meat evenly. If the meat is cut unevenly, pound it out to one thickness to ensure even cooking. If the gallon-sized sealable plastic bag was damaged while pounding the meat, replace it with a new one.
- Now make the marinade by mixing together the balsamic vinegar, Braggs Liquid Aminos, olive oil, Worcestershire, garlic cloves, dried Italian seasoning, and ground black pepper.
- Pour the marinade into the bag containing the meat. Remove the air from the bag, and seal it. Use your hands to squish the bag and move the London broil around until it’s completely coated in the marinade.
- Place the bagged London broil in a medium-sized baking dish, and place the dish in the refrigerator. Marinate for at least 4-6 hours, or overnight if you prefer a stronger flavor.
- Pull the meat out from the refrigerator to warm up 45 minutes before grilling.
- Preheat a grill to 400 degrees (F), discard the marinade, and grill the London broil for about 9 to 11 minutes on each side, or until the meat registers your preferred desired temperature (125 F - rare, 135 F - medium rare, 145 F - medium, 150 F - medium well, 160 F - well done).
- Place the meat in a heat safe dish, and allow it to rest for at least 10 minutes. Slice against the grain (this is my absolute favorite knife for slicing meat), and serve immediately.
