What You’ll Need For London Broil
- Beef: The term “London Broil” refers to the cooking method not the cut of beef. Look for cuts labeled London Broil or flank steak, or use skirt steak or top round steak.
- Oil: Use olive oil or any light-flavored oil.
- Acid: Balsamic vinegar is the acid in this marinade; it’s needed to break down the meat and tenderize it.
- Flavor: Soy sauce adds salt and umami, while garlic and herbs add flavor.
- Butter: A bit of melted butter before broiling/grilling helps with browning.
How to Cook London Broil

Pro Tips
- An instant-read meat thermometer will ensure London Broil is not under or overcooked. Properly cooked steak should read 125°F for rare up to 130°F for medium-rare.
- Once the steak is cooked to your liking, it will continue to cook as it rests, so you can pull the steak a few degrees shy of those numbers if desired and wrap it in aluminum foil.
- Cutting across the grain is a simple trick for tender meat! The grain is the direction of the muscle fibers, and when you slice against it, you make those fibers shorter and for more tender bites.
Leftovers?
- Store leftover London Broil in an airtight container in the refrigerator for up to 4 days.
- Leftovers are great in Beef Barley Soup or as a steak sandwich.
- Freeze London Broil in a zippered bag for up to one month and thaw in the refrigerator before serving cold or reheating.
