Easy London Broil Marinade Recipe - Just 4 Ingredients! (2024)

My go-to london broil marinade recipe with mustard, balsamic vinegar and garlic. This tender cut of beef is a family favorite. Everyone is happy when mom makes London Broil for dinner!

I picked up a London Broil the other day on sale at Publix. I wanted to treat my husband to a good steak dinner….since that is his favorite…and since I’m watching my calories, I compromised by picking up a leaner cut of beef like this one so I wouldn’t feel too guilty eating it with him. I love how economical London Broil is…it’s often on sale and you can get several meals from one good sized steak.

I made the best London Broil recipe again recently and my family raved about it. I must still not be cooking steak for them very often, ha ha. It’s still a treat.

What’s a good marinade for London Broil?

I have been making this marinade for London Broil for over 10 years and it is absolutely delicious. All you need is balsamic vinegar, dijon mustard and lots of garlic to create the best marinade for your London Broil – just 4 ingredients. Make sure to let it marinate for a few hours in the refrigerator to get the full flavor.

My steak marinated for about 5 hours, but you can easily let it sit in the marinade overnight and/or all day…the longer the better as far as I’m concerned.

Always make sure to include an acid in your marinade, like vinegar or citrus. This helps tenderize the meat.

Ingredients for London Broil marinade:

This marinade makes about 1/3 cup and works well for a 1 1/2 pound cut of beef. I like to place my beef in a large ziplock bag or Pyrex storage dish to marinate. Be sure to move the meat around in the marinade periodically by massaging it through the ziplock bag or flipping it over in the storage dish.

• 1/4 cup Balsamic vinegar
• 2 TB stone ground Dijon mustard
• 1 TB Worcestershire sauce
• 4 garlic cloves, minced (or less depending on your love of garlic!)

What is the best way to cook London Broil?

In the oven, with high heat. I’m sure it would be great on the grill too, but I have only cooked London Broil this way in the oven. Make sure to bring your meat to room temperature before placing in hot oven – this will help it cook more evenly.

1. Preheat oven to 450 degrees. Using tongs, pull steak out of ziplock bag and place on broiler pan. Spoon over about 2 tablespoons of marinade over steak.
2. Place in oven a cook for approximately 5-7 minutes per side (for a 1 inch steak) for medium. Add more time for a thicker steak or if you like it more well done (I recommend medium rare – medium for most tender).
3. Once steak is done cooking, let rest on cutting board for at least 5 minutes before slicing. Make sure to slice against the grain (click here for a demo).

What should I serve with London Broil?

To keep things simple, I decided to roast some tomatoes and asparagus in the oven as well. Any roasted vegetables or potatoes would make a delicious side dish for this meal. We love these Roasted Red Potatoes with Smoked Paprika and make them often.

Here’s the recipe for easy Roasted Asparagus. For the tomatoes, roast plum tomato halves at the same time, with a little drizzle of olive oil, salt and pepper. If you have fresh basil, sprinkle it over the tomatoes at the end.

What to do with your leftovers? Here are some great ideas for your London Broil leftovers:

I love serving leftover London Broil over a salad for lunch the next day, like this Steak Spinach Salad. Leftover sliced beef is great to add to quesadillas or stir fry too. Try it in something like this Thai Curry Spaghetti Squash– this recipe is delicious!
