Flank steak is a popular cut of beef that is known for its rich flavor and versatility. However, many people are unsure where the grain runs on a flank steak, which can make it tricky to prepare and slice properly. In this article, we’ll explore where the grain is on flank steak and how to identify it.

What is Flank Steak?

Flank steak comes from the abdominal muscles of the cow and is a lean, flavorful cut of meat. It’s often used in dishes like fajitas, stir-fry, and sandwiches. However, because it’s a tougher cut of meat with long muscle fibers, it can be difficult to cook properly.

Where Is the Grain on Flank Steak?

To understand where the grain is on flank steak, you need to know what muscle fibers are. Muscle fibers are long strands of cells that run parallel to each other within a muscle. The direction these fibers run determines the direction of the grain.

On a flank steak, you’ll notice that the muscle fibers run diagonally across the meat. The grain is easy to see if you look closely – it looks like lines running across the surface of the meat at an angle.

How to Identify the Grain

To identify the grain on flank steak, look for these telltale signs:

  • Lines: As mentioned above, look for lines running diagonally across the surface of the meat.
  • Texture: Run your fingers over the surface of the meat – you should be able to feel that one direction is smoother than another.
  • Cut: If you’re still having trouble identifying which way the grain runs after looking at lines and feeling texture, try making a small cut against the grain with a sharp knife. You should be able to see which way the muscle fibers run.

Why Is It Important to Know Where the Grain Runs?

Knowing where the grain is on flank steak is important for a few reasons:

  • Tenderness: Slicing flank steak against the grain makes it more tender because it shortens the muscle fibers. If you slice with the grain, you’ll end up with tough, Chewy meat.
  • Presentation: Slicing against the grain also makes for a more visually appealing presentation. The meat will have a more uniform texture and won’t look stringy.

How to Slice Flank Steak Against the Grain

Now that you know where the grain is on flank steak and why it’s important, let’s talk about how to slice it properly.

  1. Identify which way the grain runs by using one of the methods described above.
  2. Position your knife perpendicular to the grain.
  3. Slice across the grain into thin strips, making sure to maintain a consistent angle and thickness.


Flank steak is a delicious and versatile cut of beef that can be used in many different dishes. However, it’s important to know where the grain runs so you can slice it properly. By following these tips, you’ll be able to prepare tender, flavorful flank steak every time!
