I’ve tried a lot of marinades for flank steak, but this one is my favorite. It’s a great way to prepare an inexpensive and otherwise tough piece of meat.
The longer you marinate your London Broil, the more tender it will be. I definitely recommend overnight if possible.
I like to grill mine about 6-8 minutes per side, but your cooking time will vary based on the thickness of your steak and how you like it cooked.
Flank steak and London broil are both the same cut of meat. London broil is actually a method of cooking flank steak. Nobody really knows where the name originated, but it probably wasn’t in London, England. You will find either label used in grocery stores.
I highly recommend serving this with a side of Parmesan Garlic Roasted Potatoes.
