If you’re not familiar with London broil, perhaps it’s time to experiment with something new. You can learn to cook London broil on the grill, in the oven, in an air fryer, or however you prefer to cook it, really. 


Regardless of the cooking method you choose, there’s one thing you should remember when it comes to London broil: This steak needs a good marinade to truly become a mouthwatering staple on your dinner plate. Continue reading this guide to learn how to create the perfect London broil marinade.

Tips for the Perfect London Broil Marinade

First, let’s start with the basics. A good steak marinade needs fat, acid, and flavor. For London broil, the fat usually comes from olive oil or a similar type of oil, and the acid usually comes from beef-friendly ingredients like balsamic vinegar, red wine vinegar, or Worcestershire sauce. 

The “flavor” part can really go many different ways. This is where you’ll add in your spices and herbs, like black pepper, minced garlic, thyme, paprika, or chili powder. Whatever herbs and spices you love most for steak, feel free to add them to your marinade. 

Just be sure their flavor profiles work together well. For example, a sweeter marinade might call for a little nutmeg or brown sugar, which probably wouldn’t pair well with something more savory like garlic. Meanwhile, an Asian-inspired marinade might use sesame oil, orange juice, garlic, and ginger, but adding in rosemary might throw off those flavors.

Another tip: Make sure your entire steak is covered in the marinade for best results. This ensures that all parts of the meat get the benefits of the marinade, including tenderizing and flavoring the steak.

Finally, give the steak several hours to marinate in the refrigerator. If possible, let the steak marinate for the full night before you’re ready to cook it. If you can’t do that, allow it to marinate for at least 2-4 hours.
