If you’re a fan of Mexican cuisine, then you’re probably familiar with fajitas. Fajitas are a popular dish made with grilled meat, usually beef or chicken, served with tortillas and various toppings like salsa, guacamole, and sour cream.

The key ingredient in fajitas is the meat. While chicken is often used in fajitas, beef flank steak is the traditional choice for an authentic taste.

But how do you cut flank steak for fajitas? Follow these steps to get perfectly sized strips of beef for your next fajita feast.

Step 1: Choose the Right Flank Steak

First things first, choose a good quality flank steak. Look for one that is bright red in color and has visible marbling.

Marbling refers to the white streaks of fat that appear throughout the meat. This fat helps to keep the meat tender and juicy during cooking.

Step 2: Freeze Slightly

Before cutting your flank steak, freeze it slightly for about 30 minutes. This will make it easier to slice thinly and evenly.

Step 3: Cut Against the Grain

The most important step in cutting flank steak for fajitas is to cut against the grain. The grain refers to the lines of muscle fibers that run through the meat. Cutting against the grain means slicing perpendicular to these lines, which makes the meat more tender and easier to chew.

To identify which way the grain runs in your flank steak, look for the lines of muscle fibers running across it. Once you’ve found them, use a sharp knife to slice across them into thin strips. Aim for slices that are about ¼ inch thick.

Step 4: Cut into Bite-Sized Strips

After slicing your flank steak against the grain into thin strips, cut those strips into bite-sized pieces. This will make it easier to cook and eat your fajitas.

Step 5: Marinate or Season

Now that your flank steak is sliced and ready to go, it’s time to add some flavor. You can marinate your steak for a few hours before cooking to infuse it with flavor, or simply season it with salt, pepper, and any other spices you like.

Step 6: Cook and Enjoy

There are many ways to cook flank steak for fajitas, but the most common method is to grill it over high heat for a few minutes on each side. You can also pan-fry or broil your steak if you don’t have access to a grill.

Once cooked, serve your thinly sliced flank steak with warm tortillas and all the toppings you desire. Enjoy!

  • Tips:
  • If you don’t have access to a grill, you can also cook your flank steak in a cast-iron skillet.
  • Don’t overcook your flank steak! It should be cooked quickly over high heat for maximum tenderness.


Cutting flank steak for fajitas is easy once you know the right technique – cut against the grain! Follow these steps and you’ll have perfectly sized strips of tender beef ready for your next Mexican feast.

Don’t forget to season or marinate your meat before cooking and serve it up with all the toppings you desire. Enjoy!
