London Broil Crockpot Recipe

Chef Justin , On March 20, 2023

This London broil crockpot recipe uses flank steak.

This Crockpot London broil recipe has a rich, beefy flavor with a slightly gamey taste. Since I am using flank steak for this London broil crockpot recipe, it has a firm texture and is lean, making it a healthy option. If you were using a leaner cut of red meat for this London broil recipe like a top round (this dries out fast) I would recommend allowing the meat to be submerged in a brining solution to inject moisture in the meat. Since flank is already quite tender I opted to use a marinade to inject flavor. The marinade I use in this London Broil crockpot recipe has a combination of ingredients such as soy sauce, Worcestershire sauce, red wine, garlic, and savory herbs such as thyme and rosemary. These ingredients not only add flavor to the meat, but they also tenderize it, making it more succulent and juicy. The outcome is a delicious London Broil crockpot recipe you won’t want to miss.
