In a large zipper bag add the vegetable oil, balsamic vinegar, lemon juice, dijon mustard, Worcestershire sauce, soy sauce, Italian seasoning blend and crushed red pepper.
Smoosh the mixture until it’s combined.
Add beef to the bag and smoosh it around until it’s fully coated.
Refrigerate for 12-24 hours.
Preheat grill to medium high heat.
Remove beef from the marinade and place on preheated grill. Discard marinade.
Grill for 9-10 minutes then flip the beef.
Grill for another 9-10 minutes or until beef is desired temperature.
Let London Broil rest for 5 minutes before slicing against the grain.
Notes
Easy to Cook: You want to pull the meat when it hits 110 internal. Once the London Broil hits 110 internal, it’s time to sear it. To seal in the juices.
Garlic: I love to add a little minced garlic to the marinade to change up the flavor!
It is Better with Butter: After you have cut your grilled London broil steak, finish it off with a little compound butter!
