Flank steak is a flavorful cut of meat that is often used in dishes like fajitas, stir-fries, and steak salads. However, it can be tough if not cooked properly. In this article, we will look at different methods to tenderize flank steak.


One of the best ways to tenderize flank steak is by marinating it. Marinating involves soaking the meat in a mixture of acidic ingredients like vinegar, citrus juice, or yogurt along with seasonings like garlic and herbs. The acid in the marinade breaks down the tough muscle fibers in the meat and makes it more tender.

  • Make a marinade by combining ¼ cup of olive oil, ¼ cup of soy sauce, 2 tablespoons of Worcestershire sauce, 1 tablespoon of brown sugar, 1 tablespoon of minced garlic and 1 tablespoon of red wine vinegar.
  • Place the flank steak in a resealable plastic bag and pour the marinade over it.
  • Seal the bag and refrigerate for at least an hour or up to overnight. The longer you marinate the meat, the more tender it will become.


Another method to tenderize flank steak is by pounding it with a meat mallet. This breaks down the muscle fibers and makes them more tender.

  • Place your flank steak on a cutting board and cover it with plastic wrap.
  • Pound the steak with a meat mallet until it’s about ¼ inch thick.
  • Cut the flattened steak into pieces and cook them as desired.

Cooking Methods

The way you cook your flank steak can also affect its tenderness.

  • Grilling or broiling the steak quickly over high heat can help to keep it tender.
  • Cooking the steak slowly over low heat, such as in a slow cooker or braising, can also help to make it more tender.
  • Letting the steak rest for at least five minutes before slicing it against the grain will also make it more tender.


In conclusion, flank steak can be tough if not cooked properly. However, by marinating it with acidic ingredients, pounding it with a meat mallet, and cooking it using certain methods, you can make this flavorful cut of meat more tender. Try out these methods and enjoy a delicious and tender flank steak!
