Instructions
London Broil Marinade
In a Ziplock storage bag, mixing bowl, or brining container, combine the ingredients for your marinade (balsamic vinegar, Worcestershire sauce, soy sauce, olive oil, Dijon mustard, garlic, black pepper, salt, and optional thyme or oregano).
Prep your steak by tenderizing both sides with a meat mallet, then use a sharp knife to cut the surface of the meat in a criss-cross pattern. *Tenderizing your London broil is highly recommended.
Add your London broil to the marinade, submerging it as much as possible. If using a bag, squeeze the marinade around the steak so it is touching all sides. Place it in the fridge to marinate for at least 30 minutes, but preferably a few hours. You may leave it for up to 24 hours, but no longer.
London Broil
Move the top oven rack to the second from highest position and set your oven to broil on high (or just 'broil' if your oven doesn't have a high/low setting).
Remove the steak from the marinade and place it onto a broiler pan or a wire rack set over a rimmed baking sheet. *Alternatively you may line a tray or pan with foil.
Place the London broil on the center of the top rack and broil for 7 minutes per side for medium-rare (9 minutes per side for medium).
Remove the steak from the oven and cover it loosely with a piece of foil. Let it rest for 10 minutes, then slice against the grain and serve.
Notes
This marinade will be delicious on any steak and does not exclusively have to be used on a London broil.
If you have the time, it is best to set the meat out on the counter to come to room temperature before cooking. This takes 30 minutes to 1 hour, but it will help your London broil cook evenly.
Always dispose of marinade after it has come in contact with raw meat or you risk exposure to foodborne illnesses.
To store: If you'd like to make the marinade in advance, store the unused marinade in an airtight container in the fridge and use it within 1 week.
