Flank steak is a versatile and flavorful cut of meat that can be cooked in many ways. However, to get the best results, it needs to be marinated properly.

Marinating helps to tenderize the meat and infuse it with flavor. But how long should flank steak be marinated? Let’s find out.

What is Flank Steak?

Before we dive into the marinating process, let’s understand what flank steak is. Flank steak is a cut of beef that comes from the abdominal muscles of the cow. It’s a lean and tough piece of meat that requires proper cooking techniques to make it tender and juicy.

Why Marinate Flank Steak?

As mentioned earlier, flank steak is a tough cut of meat, which means it needs some extra love and care before cooking. Marinating helps to break down the fibers in the meat, making it more tender and easier to chew. Additionally, marinating allows you to add flavor to the meat by infusing it with herbs, spices, acids, or oils.

How Long Should You Marinate Flank Steak?

The ideal marinating time for flank steak depends on several factors such as thickness, acidity level of the marinade, and personal preference. In general, a minimum of 30 minutes is required for the marinade to penetrate the surface of the meat.

For more flavor and tenderness, you can marinate your flank steak for up to 24 hours. However, if you’re using an acidic marinade (such as vinegar or citrus juice), don’t leave the steak in for too long as this can cause it to become mushy.

Here’s a simple yet delicious marinade recipe for your flank steak:

  • 1/4 cup soy sauce
  • 2 tablespoons olive oil
  • 1 tablespoon Worcestershire sauce
  • 1 tablespoon honey
  • 2 cloves garlic, minced

Mix all the ingredients together in a bowl and pour over your flank steak. Cover the dish with plastic wrap or put it in a ziplock bag and refrigerate for at least 30 minutes.

Cooking Flank Steak

Once marinated, you can cook your flank steak using various methods such as grilling, broiling, or pan-frying. Make sure to pat the meat dry before cooking and discard any leftover marinade.


In summary, marinating is an essential step when it comes to cooking flank steak. The ideal marinating time is between 30 minutes to 24 hours, depending on personal preference and marinade acidity levels.
