If you want to know how to cook skirt steak on grill, you need to start with the right technique. Skirt steak benefits from high, direct heat and should be sliced against the grain after resting. This cut is thin, flavorful, and cooks fast, making it a favorite for tacos, salads, or a simple steak dinner. Follow this guide for a perfectly charred, tender result every time.
Skirt steak comes from the plate section of the cow. It has long muscle fibers and a loose grain. When you grill it right, it turns out juicy and beefy. But get it wrong, and it can be tough or chewy. The key is heat management and proper slicing.
Understanding Skirt Steak Before You Grill
Before you fire up the grill, know your meat. Skirt steak is not the same as flank steak or hanger steak. It is thinner and more porous, so it absorbs marinades quickly. It also cooks faster than most steaks.
There are two types of skirt steak: inside skirt and outside skirt. Outside skirt is thicker, more tender, and harder to find. Inside skirt is more common but can be a bit tougher. Both work great on the grill if you treat them right.
Choosing The Best Skirt Steak
Look for steaks with even thickness. Avoid pieces that are too thin at one end. A uniform cut cooks more evenly. The meat should be deep red with some marbling. Fat adds flavor and moisture.
If you can, buy the whole skirt steak and cut it into grill-friendly portions. A typical skirt steak weighs about 1 to 1.5 pounds. That feeds two to three people.
Trimming And Prepping The Meat
Skirt steak has a thin membrane called silver skin on one side. Use a sharp knife to remove it. Leaving it on makes the steak chewy. Also trim any large pieces of hard fat.
Pat the steak dry with paper towels. Moisture on the surface prevents a good sear. Dry meat browns better and develops a crust.
How To Cook Skirt Steak On Grill
Now we get to the main event. Follow these steps for a steak that is charred outside and pink inside.
Step 1: Season Or Marinate
Skirt steak loves bold flavors. You can keep it simple with salt and pepper, or use a marinade. A classic marinade includes lime juice, garlic, cumin, and oil. But do not marinate too long. The acid can break down the meat and make it mushy. 30 minutes to 2 hours is plenty.
If you dry season, apply kosher salt at least 40 minutes before grilling. This lets the salt penetrate and season the meat evenly. Fresh cracked black pepper goes on just before grilling.
Step 2: Preheat The Grill
Skirt steak needs high heat. Preheat your gas or charcoal grill to 450-500°F. You want a hot fire that sears the meat quickly. For charcoal, let the coals turn white-hot before cooking.
Clean the grates with a wire brush. Then oil them with a paper towel dipped in vegetable oil. This prevents sticking and helps create grill marks.
Step 3: Grill Over Direct Heat
Place the steak directly over the hottest part of the grill. Cook for 3-4 minutes per side for medium-rare. Do not move the steak around. Let it sit and develop a crust.
Flip only once. Use tongs, not a fork, to avoid piercing the meat. The steak is thin, so it cooks fast. Keep an eye on it to avoid overcooking.
Step 4: Check Doneness
Use an instant-read thermometer for accuracy. For medium-rare, aim for 130-135°F. For medium, go to 140-145°F. Skirt steak is best served medium-rare to medium. Well-done skirt steak gets tough.
If you do not have a thermometer, use the finger test. Press the steak with your index finger. It should feel like the fleshy part of your palm when your thumb touches your index finger.
Step 5: Rest The Steak
Resting is non-negotiable. Transfer the steak to a cutting board and let it sit for 5-10 minutes. Tent loosely with foil to keep warm. Resting lets the juices redistribute so they do not run out when you slice.
Step 6: Slice Against The Grain
This is the most important step. Look at the direction of the muscle fibers. They run lengthwise along the steak. Cut perpendicular to those fibers. This shortens the fibers and makes each bite tender.
Slice the steak into thin strips, about 1/4 inch thick. Angle your knife at 45 degrees for wider slices. Serve immediately or keep warm.
Common Mistakes When Grilling Skirt Steak
Even experienced cooks make errors with this cut. Avoid these pitfalls for better results.
- Overcooking: Skirt steak dries out fast. Cook to medium-rare or medium at most.
- Skipping the rest: Cutting too soon releases all the juices. Let it rest.
- Wrong slicing: Slicing with the grain makes the steak chewy. Always cut against the grain.
- Low heat: Skirt steak needs high heat for a good sear. Low heat makes it gray and tough.
- Too much marinade: Acidic marinades can turn the meat mushy if left too long.

Classic Citrus Marinade

Serving Suggestions For Grilled Skirt Steak
Skirt steak is versatile. Here are some ways to serve it.
- Tacos: Slice thin and serve in warm corn tortillas with salsa, cilantro, and lime.
- Steak salad: Slice over mixed greens with avocado, tomatoes, and a vinaigrette.
- Rice bowl: Serve over cilantro lime rice with black beans and grilled vegetables.
- Simple steak dinner: Pair with roasted potatoes and a side of chimichurri sauce.
Chimichurri is a classic match for skirt steak. It is a fresh herb sauce made with parsley, garlic, vinegar, and oil. Drizzle it over the sliced steak for extra flavor.
How To Store And Reheat Leftover Skirt Steak
If you have leftovers, store them properly. Place the sliced steak in an airtight container. Refrigerate for up to 3 days.
To reheat, use a skillet over medium heat. Add a splash of beef broth or water. Cover and heat for 2-3 minutes. This prevents drying out. You can also reheat in the microwave on low power, but the texture may suffer.
Cold skirt steak works great in sandwiches or salads. Slice it thin and add to a wrap with lettuce and dressing.
