The Differences Between Skirt Steak And Flank Steak
As you can sort of see above, there aren’t major differences between skirt steak and flank steak. This is another reason recipes that call for either steak can be substituted for one another quite easily.
With that said, the major difference between flank steak and skirt steak is the fat content. Skirt steak has more fat/marbling than flank steak, and as the saying goes, fat is flavor.
Truth be told, flank steak has very little fat, if any.
Another difference is in the size of the meat. Skirt steak is a long , thin cut of meat . Flank steak is a roughly 10-12 inches long and 5-6 inches wide. However both are only at most 1/2 to 1 inch thick.
While both cuts of meat consist of tough muscle fibers, flank steak has a tighter grain where-as skirt steak is loser yet more fibrous. Meaning, Skirt steak will take better to marinades than flank steak.
The Inside Skirt Steak
The inside skirt steak is obtained from below the ribs of a cow. It is a fatty and chewy kind of meat that often the butcher removes its membrane before selling it. This explains why it is an easy cut to cook. In addition, the inside steak is tougher, thinner, and more irregular in shape when compared to the outside skirt steak.
What Is Outside Skirt Steak
As you might have already guessed, the outside steak gets its name because it sits further towards the outside of the cow than the inside cut does. In fact, it lays across the outside of the chest wall passing from the 6th down to the 12th rib.
Because of its position and orientation, the outside skirt steak tends to be both longer and wider than the inside portion of the skirt steak. But the actual volume of meat is roughly the same as its also a much thinner cut.
In addition, it also tends to have much less fat and also doesnt have that hard membrane that needs removing .

Theres excellent marbling and fat on the outside skirt steak, making it rather suitable for grilling. This meat is tender, juicy, and has a strong beefy taste. On the other hand, the inside skirt steak is a bit more chewy and lacks the juiciness that outside skirt steak presents.
As you can well imagine, the above characteristics make the outside skirt steak a more attractive pick for most people. As such, it is more expensive.
Interestingly, when cooking, the inside skirt steak shrinks significantly while the outside skirt steak sees less shrinkage. This is largely due to the higher fat content on the inside steak. Its also a reason why commercial kitchens give a higher preference to outside skirt steak.
How Do You Know If Youre Slicing Skirt Steak Correctly
Cut off a few slices in the direction that you think is correct. Now pick up a slice and look at the cut edge. Is your slice made up of long shreds of meat that run the length of your slice? That is incorrect. You want to be cutting THROUGH those shreds of meat, not along them.
When you look at the cut edge, you should not see any defined shreds. Instead, it should look like a bunch of dots of meat pushed together. That tells you that you have cut through the shreds.
If youre having trouble visualizing this, dont worry. Take a look at the comparison photo below. You want it to look like the pieces on the left, not the ones on the right where I cut with the grain.
The final slicing tip for juicy and tender skirt steak is to let it rest. You dont want all the juices to come out when you cut into it. Instead, let the steak rest for 5 minutes before you cut into it. That way, the juices have a chance to stop moving around and to reabsorb into the meat. Dont cover it with anything while it is resting.
Tip:This electric knife is my favorite tool for perfect, even slices.

Which Is Better For Fajitas Flank Steak Or Skirt Steak
Skirt steak is the traditional cut for fajitas, but flank can work in its place. Skirt steak is better because of how well it marinades. The fibers in skirt steak arent tightly-knit, which allows the marinade and seasoning to penetrate deeper into the cut.

However, flank steak can also be used for fajitas, even if it isnt as well suited. Flank steak is a more tender cut, but with a closer knit fiber. This means that while it will hold a marinade, the flavors wont reach as deep. Flank steak has a less intense flavor, which some prefer.

The Difference In Meat Structure
The main difference between flank steak and skirt steak is their muscle fibers. Flank steak will typically have grain running along the longest direction of the cut, giving you shorter pieces of meat when cut against the grain. Strip steak tends to have grain running the short direction, giving you longer, thinner cuts.
One thing you’re going to hear a lot is that you have to cut both of these steaks against the grain. What that means is that the long strings of muscle will run in one direction and you’ll cut the steaks perpendicular to the direction the threads of muscle run.
When Would You Pick One Over the Other
Though these two cuts of meat are often used interchangeably, there are times when one is superior to the other. The key thing to remember is that skirt steak gets marinaded while flank steak does not. This is due to the structure of the muscle fibers which allow marinades to penetrate the tough fibers of the skirt steaks. Flank steak is denser and doesn’t take on much flavor from a marinade.
If you have a recipe calling for a marinade, choose skirt steak. A marinade that includes an acid like orange juice or lime juice will help to break down the tough muscle fibers and result in a more tender cut.
