Skirt Steak: A Primer

When you think of summer grilling, a few things might come to mind. Maybe it’s a classic Bacon Cheeseburger (a sure fire bet), or perhaps something a little spicier, like Chipotle Grilled Chicken. Or maybe a charred hot dog or juicy rib eye is the epitome of summer for you.

We’re a big fan of all those things, but skirt steak is quickly becoming synonymous with summer in our house. This underrated cut of meat is perfect for marinating and throwing on the grill for an ultra fast dinner.

It’s flavorful, and, if done right, extremely tender.

You could easily eat it on its own with a side of Balsamic Grilled Vegetables, but we think we’ve found skirt steak’s true purpose in life with these Skirt Steak Sandwiches.

Today, we’ll teach you how to make some killer steak sandwiches, including the BEST skirt steak marinade and tips for grilling. Soon, you might find skirt steak at the top of your grilling list too!

What is skirt steak?

Let’s start with the basics. Skirt steak is a long, narrow strip of beef that comes from the diaphragm muscles of the cow. It is a lean cut with a robust, beefy flavor. Skirt steak is available at most major grocery stores or butchers. We have found it for a great price at Aldi!

How do you make skirt steak tender?

Skirt steak has a lot of tough fibers. To keep it tender we suggest three things:

  1. Marinate the meat. Marinating helps tenderize and add flavor to the meat.
  2. Don’t cook it past medium.
  3.  Slice across the grain.

If you follow these three steps, skirt steak is a really tender, versatile, and flavorful cut of meat to add to your rotation!

How long should you marinate steak?

Skirt steak should be marinated at least 1 hour, or up to 24 hours.

The best way to cook skirt steak

Skirt steak benefits from high heat cooking for a short period of time. Because it’s so thin, it only requires 4 minutes per side for medium doneness.

What is the difference between skirt steak and flank steak? Are they interchangeable?

Flank steak is another long, thin cut of beef. It tends to be slightly more tender than skirt steak, and also have a slightly less robust flavor. That said, these cuts can be used interchangeably for things like fajitas, sandwiches, and stir fry. You can learn more about different beef cuts here.

What can I use skirt steak for?

This is the best part! Skirt steak is perfect for a variety of dishes, including tacos, stir fry, sandwiches, and salads. Basically, anywhere you might want thin slices of steak, this cut is a great fit!

I love pairing Marinated Skirt Steak with Simple Summer Salad, or sub skirt steak for flank in these Grilled Flank Steak Tacos. You can also check out this collection of 60 Beef Recipes for Every Cut for more ideas on how to use skirt or flank steak.

The Best Skirt Steak Marinade:

Skirt steak is the perfect sponge for a flavorful marinade, and this one packs a punch! It has an excellent balance of savory and citrus ingredients, with the added flavor of fresh herbs! It’s great for skirt steak sandwiches, but would also be a lovely marinade for skirt steak tacos or fajitas!

Here’s what you’ll need to make it:

  • Soy sauce- I almost always use low sodium, but either will work.
  • Olive Oil
  • Lemon zest and juice
  • Chopped fresh basil and parsley
  • Garlic
  • Red pepper flakes for a little heat
  • A hint of honey

How to Cook Skirt Steak on the Grill:

The best way to cook skirt steak is over high heat for a very short amount of time. You can cook it on the stove top, but because of the long shape of the meat, it’s easiest to do it on the grill.

To grill skirt steak:

  1. Remove the steak (in its marinade) from the fridge while the grill preheats.
  2. Oil the grill grates, then preheat the grill to high heat (500+ degrees).
  3. Place the steak on the grill and cook for 3 minutes a side or until it reaches an internal temperature of 135-145 degrees for medium.
  4. Rest the steak before slicing.

Tips for grilling steak:

These tips apply to the skirt steak, but also for almost any cut of steak you cook on the grill or stove top.

  • Salt and pepper the steak generously, even if you’re adding a marinade. I prefer Kosher or coarse sea salt.
  • Start with clean and oiled grill grates. To prevent sticking and get those lovely sear marks, always begin with clean and oiled grates. I use a paper towel dipped in vegetable or canola oil to oil the grates.
  • Flip once. Again, if you want distinct sear marks and nice char, it’s best to put the steak on the grill and leave it alone. Flip just once at the halfway point.
  • Know your temps. The most accurate way to get a steak done exactly as you prefer is to use a meat thermometer (here’s ours). Keep in mind that steak will continue to cook and rise in temperature about 5 degrees after removing from the grill. Here’s the breakdown of temperatures:
    • Rare- 125°
    • Medium Rare-135°
    • Medium-145°
    • Medium Well-150°
    • Well Done-160°
    • Note: I don’t recommend cooking skirt steak past medium, as it can get tough and chewy. If you prefer a more well done steak, try a Cast Iron Ribeye or Filet (featured in this Steak and Scallops recipe).
  • For more information on how long to cook different types of beef, visit this grilling time guidelines chart.
  • Let it rest. After cooking, tent steaks with foil and let rest for 5-10 minutes before slicing so all the yummy juices reabsorb into the meat and don’t end up all over your cutting board!
  • Slice against the grain. Slicing against the grain prevents you from trying to chew through tough fibers.

Crafting the Ultimate Steak Sandwich

I really wanted the meat to shine in this recipe, so I kept the toppings pretty simple.

  • Add some greens. I prefer arugula, but leaf lettuce or spring mix would also be great.
  • Add crunch and color with sliced radishes or cucumbers.
  • Bring it all together with a creamy sauce. Plain mayonnaise will work just fine here, but I wanted to add a touch of sweetness, so I whipped up a quick sun dried tomato basil mayo to finish the sandwich.
  • Sandwich it in a fluffy, crusty sandwich roll, like ciabatta, or a halved French baguette.
