Steak is a staple in my household. We have it at least once a week. Beef recipes are my specialty, and because I serve it so often I love to come up with ways to make each dish stand out from the others.

What is London Broil?
It refers to two things: a few different cuts of beef such as top round and flank steak, and a cooking technique used for tenderizing even the toughest steaks.
This involves marinating your beef for several hours up to overnight, then grilling it or roasting it in the oven. Finally, the beef is sliced thinly against the grain for the most tender meat.
London Broil Cut
- Top round
You can use this London Broil marinade recipe for a few different cuts of beef. The most common choices are top round and flank steak, but other budget-friendly cuts like flap and skirt work as well.
What makes this marinade so special is it's perfect for using with the most inexpensive cuts of beef. No need to worry about a tough steak - this marinade tenderizes meat beautifully!
- Use vegetable oil instead of olive oil
- Gluten-free? Replace soy sauce with tamari or coconut aminos
- Try garlic paste or fresh garlic instead of garlic powder
- Red wine vinegar is a good replacement for balsamic vinegar
- Instead of brown sugar, try honey or a mix of white sugar and maple syrup
- No ginger? Use ground allspice, cinnamon, or nutmeg
- Red pepper flakes are optional, but do add a nice kick of flavor
Can you marinate London broil too long?
Yes, you can. We recommend marinating for at least 4 hours or up to overnight. If you leave the beef marinating too long, it will start to break down. Don't leave it past 1 day.
Make Your Marinade into a Sauce
After marinating and grilling your steak, you can use the leftover marinade from the bag to create a sauce.
Pour the liquid from the bag into a skillet over medium heat on the stove. Mix and let it simmer and thicken until it forms a sauce. Serve over your beef and enjoy!
