This London broil marinade recipe will give you the best London broil with big flavor, with soy sauce, vinegar, homemade chili paste and lots of seasonings.
We're cooking up beef in the Chili Pepper Madness kitchen today, my friends, so let's fire up the grill or the broiler and get cooking!
There are so many wonderful cuts of beef out there, and I love so many of them, but today we're doing with an economical cut and we're making one of my favorites, Grilled London Broil. "London Broil" refers to the preparation of the beef - Marinate, Cook, Slice - not the cut.
You can use different cuts of beef, but I'm using top-round, which is a tougher, leaner cut with big flavor that benefits greatly from a good marinade, which is the point of this recipe.
We're talking London Broil Marinade, and this particular recipe makes the perfect London Broil. It's all about tenderizing the steak while at the same time infusing it with addictive flavor, and satisfying that spicy food crave we all enjoy.
Let's talk about how we make this flavorful London broil marinade, shall we?
London Broil Marinade Ingredients
- Peppers. I used 2-3 spicy chili peppers (chopped - I used a jalapeno, Fresno and habanero for this recipe, though you can use other peppers to your preference. Use milder peppers for less heat.
- Garlic. I use 2 cloves, though you can easily double that if you love garlic. You can also use garlic powder.
- Liquids. Use ½ cup soy sauce, 2 tablespoons apple cider vinegar and 2 tablespoon olive oil
- Seasonings. Use 1 teaspoon sugar, 1 teaspoon cayenne pepper, 1 teaspoon dried oregano, 1 teaspoon dried thyme, 1 teaspoon salt and 1 teaspoon black pepper. You can vary the ratios to your own preference.
- Hot Sauce! Optional. 1-2 tablespoons of your favorite is good, or try your favorite sriracha.
How to Make London Broil Marinade - the Recipe Method
Make the Marinade. Add the chili peppers, garlic, soy sauce, vinegar, olive oil, sugar and seasonings to a food processor. Process until very smooth.
Score the Meat. Score the London Broil on both sides with a crosshatching pattern, about ¼ inch deep to allow the marinade to penetrate the meat.
Marinate the Meat. Add the meat to a large baggie or into a wide dish and pour the marinade over it. Rub the marinade into the meat and cover. Refrigerate at least 6 hours, though it is best to marinade overnight or 24 hours for better flavor penetration.
How to Cook London Broil
FOR GRILLED LONDON BROIL
Heat the Grill. Heat a grill to medium-high heat. Very lightly oil the grates.
Grill the Meat. Grill the London Broil for 5 minutes per side. Simply grill 5 minutes, then flip and grill another 5 minutes.
Check the Temperature. You’ll want 125 degrees F internally for medium-rare or 130 degrees F for medium. Continue to grill and flip until you reach your desired temperature, up to 20 minutes TOPS.
I like to use my ThermoPop meat thermometer from ThermoWorks (I"m an affiliate). Works great!
Rest the Beef. Rest for 10 minutes, then slice up against the grain and serve.

Boom! Done! London broil is ready to serve! Such a good marinade. Pretty easy to make, isn't it? The secret is all in the flavorful marinade, with all those bold flavors. The cooking part is super easy.
The Benefits of a Marinade and How Long Should I Marinate London Broil?
Marinating not only helps to flavor beef and other foods, but it also tenderizes tougher cuts of meat, making them much more enjoyable. Typical cuts of beef used for London broil, like top-round or flank steak, are somewhat tough and tenderize the longer you marinate them.
You will get the most flavor penetration if you marinate your London broil for 24 hours, or at least overnight, though you will get great results in 6 hours. However, if you are pressed for time, you can marinate your beef for 1 hour. You will still get some flavor penetration.
Recipe Tips & Notes
- Best Cuts of Meat for London Broil. Top-round steak is sometimes labeled "London Broil" in grocery stores. Flank steak is traditional as well. You can also use skirt steak. All of these work wonderfully with a marinade.
- Other Ingredients. You can work in other flavor building ingredients if you'd like for your marinade. Popular additions include Worcestershire sauce, lemon juice or lime juice, and other seasonings.

Mike, love your recipes. Haven’t tried this one yet, but have a comment. A lot of people don’t like getting out their big food processor and all the parts. I also have a Mini-prep (very small to grind or chop, not a coffee grinder type). I use it all the time to grind nuts, make marinades, even small amounts of pesto. It only has the single blade. Perfect for the job. Sometimes, if I see a recipe needs lots of equipment, I just pass it by. This looks like I can use my mini-prep. Just a suggestion to maybe mention mini-prep Or food processor.

Thanks, Carol. Yes, I use my small food processor all the time for this and many recipes. Smart idea.

Unfortunately, I probably overcooked the meat, but the flavor was amazing, incredible!
This day was a sad, a very dark day here, for me, Mike, but this meal was its rainbow! and I thank you very much.
