Wagyu skirt steak is what happens when the most flavorful cut on the case meets the most marbled beef there is - and the whole thing comes together with nothing but salt, pepper, and high heat. Skirt is loose-grained, beefy, and built to drink up a hard sear. Wagyu makes it richer still: ribbons of fat that render fast over the fire and leave you with a steak that tastes like it took all day, in a cook that takes about eight minutes.
Here is the thing about skirt: it is thin, it is fatty, and it punishes you for two mistakes - cooking it too long and slicing it the wrong way. Get those right and it is the easiest steakhouse-quality dinner you will make all summer. We shot this one on the grill because that is where wagyu skirt is happiest, but it cooks just as well in a ripping-hot cast iron skillet indoors - same heat, same timing, no deck required. It is the same fast, high-heat logic behind our wagyu strip steak and the indoor crust on a cast iron filet mignon. Salt it, pepper it, get the heat screaming, and slice it thin against the grain.

Why You'll Love This Wagyu Skirt Steak
- The most flavor for the least effort - skirt is the beefiest cut on the case, and wagyu marbling pushes it over the top.
- Grill or indoors, your call. We grilled it, but a screaming-hot cast iron skillet gives you the same crust with no deck required.
- Fast. Thin steak, high heat - about two to three minutes a side and you are resting it.
- Just salt and pepper. No marinade, no compound butter, no fuss. Great wagyu does not need dressing up.
- The slice makes the steak. Cut it thin and against the grain and even the leanest bite is tender.
Wagyu Skirt Steak Ingredients
Three things, and one of them is the steak. The whole point of wagyu skirt is that it needs almost nothing. See the recipe card below for exact quantities.
- Wagyu skirt steak, about ½ inch thick (outside skirt if you can get it)
- High-smoke-point oil (avocado or grapeseed), just to coat
- Kosher salt and freshly cracked black pepper
- Flaky finishing salt - Florida Pure Sea Salt Pure Flaked
Wagyu Skirt Steak Time & Temp Calculator
Pick your cook surface and target doneness and the calculator returns your sear time per side, the total cook, the temperature to pull at, and where the steak lands after it rests. Skirt is thin and uniform, so the cook is all about surface heat and timing - not thickness.
Find Your Cook Time
Pick your cook surface and target doneness. The calculator returns your sear time per side, the total cook, the temperature to pull at, and the final internal after the steak rests. Skirt is thin and uniform, so heat and timing matter more than thickness.
Why high heat and a short cook
Skirt steak is thin and loose-grained, and wagyu skirt is heavily marbled on top of that. The danger is not a cold center — it is overcooking. Over a screaming-hot surface the outside chars and the inside comes up to temperature almost at the same time, so two to three minutes a side is usually all it takes. Pull it at medium rare, rest it briefly, and slice thin against the grain. Push skirt past medium and the same fibers that make it so beefy turn chewy.
USDA recommends 145°F internal for whole-cut beef. Medium rare at 130°F is a culinary standard. Pregnant, immunocompromised, very young, or elderly diners should cook to 145°F.
How to Grill Wagyu Skirt Steak
High heat, short cook, sharp knife. Exact times are in the recipe card. Everything here works the same in a cast iron skillet indoors - just swap the grill for a ripping-hot pan.
Temper, dry, and season
Pull the skirt out of the fridge 30 minutes ahead and pat it bone-dry. A dry surface is what gives you a crust instead of a steam bath. Rub it lightly with oil, then season generously with kosher salt and pepper on both sides. That is the entire seasoning.
Get the heat screaming
Build a hot, direct fire - or heat a cast iron skillet over high heat until it just begins to smoke. Wagyu skirt wants the hottest surface you have. If you are grilling, leave yourself a cooler zone to slide to, because the rendering fat will flare.
Sear hard and fast
Lay the steak down and do not move it for two to three minutes. Flip once and sear the second side. Watch for flare-ups - wagyu renders a lot of fat, so slide to the cooler zone if the flames jump. You are building char and rendering fat, fast.
Pull early
Skirt is thin, so it climbs fast. Check the internal temperature in the thickest part and pull at 125 to 130°F for medium rare. Do not take it past medium - skirt gets chewy when it is overcooked.
Rest and slice against the grain
Rest the steak 5 minutes. Find the direction of the long muscle fibers and slice thin, straight across them, on a slight angle - this is the difference between tender and tough. Finish the slices with flaky Florida Pure Sea Salt and serve.
Grill or Cast Iron? How to Cook Wagyu Skirt
This is the one real decision, and there is no wrong answer.
- Grill (our pick). A hot, direct fire gives wagyu skirt a little smoke and a serious char, and the open grates let the rendering fat drip away instead of pooling. Keep a cooler zone to dodge flare-ups, because there will be flare-ups.
- Cast iron indoors. A ripping-hot skillet builds an even, edge-to-edge crust and is the move when there is no grill or no weather for it. Open a window and run the fan - wagyu skirt smokes. Pour off rendered fat between steaks if you are cooking more than one.
- Broiler. No grill, no skillet space? Run the broiler on high with the steak close to the element. It is the least control but it gets the job done in a pinch.
Substitutions
- No wagyu skirt? Regular skirt steak works the same way - same heat, same timing, same against-the-grain slice. You will lose some marbling-driven richness, so a flaky-salt finish matters even more.
- No outside skirt? Inside skirt or flank steak both take to this method. Flank is a touch thicker, so give it an extra minute a side and watch your pull temp.
- No avocado or grapeseed oil? Any neutral, high-smoke-point oil works - refined canola or light olive oil. Skip extra-virgin and butter; both burn before the surface is hot enough.
- Different finishing salt? Any flaky sea salt works in a pinch, but the larger, crisp flakes of Florida Pure Sea Salt give you that gentle crunch on the first bite.
Variations
- Tacos. Thin against-the-grain slices of wagyu skirt are the best carne asada you will ever fold into a tortilla. Char a few and pile them up.
- Steak salad. Fan the slices over greens with a sharp vinaigrette - the richness of the wagyu plays against something bright and acidic.
- Surf-side board. Slice it, shower it with flaky salt, and set it out on a wood board to pass around after a day on the water. No plates required.
- Garlic-rubbed. Want a little more without leaving simple behind? Rub the rested steak with a halved raw garlic clove before slicing. Still basically salt and pepper.
Storage
Refrigerate leftover sliced skirt in an airtight container for up to 3 days. Reheat gently, or not at all - skirt is fantastic cold over a salad. To warm it, use a low 250°F oven just until heated through, since a hard reheat turns an already-cooked thin steak tough. Cooked skirt does not freeze well; freeze the raw steak instead and thaw fully in the fridge before cooking.
Top Tip - Slice Against the Grain
Skirt steak has long, obvious muscle fibers, and if you cut with them, even wagyu turns chewy. Look at the steak, find the direction the fibers run, and slice straight across them on a slight angle into thin strips. Do that and the leanest bite is tender. It is the single most important move in the whole recipe - more than the heat, more than the temp.
The fire handles the char. The grain handles the slice.
About two to three minutes per side over a hot, direct fire. Skirt is thin - usually around half an inch - so it cooks fast. Pull at 125 to 130°F for medium rare and don't take it past medium, or it turns chewy.
Yes. A ripping-hot cast iron skillet gives you the same hard crust and the same fast cook - about two to three minutes a side. Open a window and run the fan, because wagyu skirt renders a lot of fat and will smoke. A broiler on high works too.
No. Marinades are a workaround for tougher, less flavorful skirt. Wagyu skirt is so marbled and beefy that salt and pepper is all it needs - anything more just covers up what you paid for.
Almost always one of two things: it was overcooked, or it was sliced with the grain instead of against it. Keep it at medium rare to medium, and slice thin, straight across the muscle fibers. Those two fixes solve nearly every chewy skirt steak.

Instructions
- Take the skirt steak out of the fridge 30 minutes before cooking. Pat it completely dry with paper towels.
- Rub the steak all over with the avocado oil.
- Season both sides with the kosher salt and black pepper.
- Heat a grill (or cast iron skillet) over high heat until very hot - a grill should be ripping hot, a skillet should just begin to smoke.
- Lay the steak down and sear without moving it for 2 to 3 minutes, until a deep brown crust forms.
- Flip the steak and sear the second side for 2 to 3 minutes. If grilling, slide it to a cooler zone if flare-ups jump up.
- Check the internal temperature in the thickest part. Pull at 125 to 130°F for medium rare.
- Move the steak to a board and rest for 5 minutes.
- Find the direction of the long muscle fibers. Slice the steak thin, straight across the grain, on a slight angle.
- Sprinkle the sliced steak with flaky sea salt and serve.
Notes
- Pull early - skirt is thin and keeps cooking as it rests. Pulling at 125-130°F lands medium rare. Don't take skirt past medium; it turns chewy.
- Slicing against the grain is the most important step. With the grain, even wagyu skirt is chewy; across the grain, it's tender.
- Wagyu skirt renders a lot of fat. On a grill, keep a cooler zone for flare-ups. Indoors, run the vent fan.
