Flank steak is a delicious cut of beef that can be used for a variety of dishes. However, it can be tough if not marinated properly.

Marinating is the process of soaking meat in a seasoned liquid to enhance its flavor and tenderness. In this article, we will explore how you can marinate flank steak quickly.

Choose the Right Marinade

The first step in marinating flank steak quickly is to choose the right marinade. You want a marinade that is acidic enough to help tenderize the meat but not too acidic that it overpowers the flavor. Some popular marinade ingredients include vinegar, citrus juice, soy sauce, and Worcestershire sauce.

Quick Marinade Recipe

  • 1/4 cup soy sauce
  • 1/4 cup olive oil
  • 2 tablespoons brown sugar
  • 1 tablespoon Dijon mustard
  • 2 cloves garlic, minced
  • 1 teaspoon black pepper

Simply mix all the ingredients together in a bowl and pour over your flank steak.

Cut Against the Grain

Another tip for quick marination is to cut against the grain. The grain refers to the direction of muscle fibers in the meat. Cutting against the grain means slicing perpendicular to these fibers, which makes it easier for the marinade to penetrate and tenderize the meat.

Vacuum Seal for Quick Results

If you’re really short on time, consider vacuum sealing your flank steak with your marinade. This method will infuse your meat with flavor quickly and efficiently.

Simply place your meat and marinade in a vacuum-sealed bag and remove the air using a vacuum sealer. Let the steak sit for 30 minutes to an hour, and you’ll have perfectly marinated flank steak.


Marinating flank steak doesn’t have to take hours. With the right marinade, cutting against the grain, and vacuum sealing, you can have deliciously tender flank steak in no time.

Remember to experiment with different marinades and flavors to find what works best for you. Happy cooking!
