Chimichurri Skirt Steak

Method

1. Make the chimichurri first — combine parsley, cilantro, garlic, olive oil, red wine vinegar, red pepper flakes, oregano, and salt in a bowl. Stir well and set aside at room temperature. The sauce needs at least 15 minutes for the flavors to meld. The vinegar tames the raw garlic bite while the oil pulls flavor from the herbs.

2. Pat the skirt steak dry with paper towels — this is critical. Moisture on the surface creates steam instead of sear. Season generously with coarse salt and black pepper on both sides. Let it sit at room temperature for 10 minutes while the chimichurri develops.

3. Heat a cast iron skillet over the highest heat your stove can produce until it's smoking. Add olive oil and swirl. Lay the steak away from you to avoid splatter. Sear for 2-3 minutes without moving — you want an aggressive, dark brown crust. The Maillard reaction happens fastest at extreme temperatures, and skirt steak's thinness means you have a narrow window.

4. Flip once and sear the other side for 2-3 minutes. For medium-rare, the internal temperature should be 130°F. Skirt steak is thin enough that you can judge doneness by touch — it should feel like the base of your thumb when you touch your index finger to your thumb. Firm but with give.

5. Rest for 5 minutes on a cutting board. Even though it's thin, resting is essential — the juices redistribute from the center to the edges. Cutting immediately sends all those juices onto the board instead of into your mouth.

6. Slice thinly against the grain at a slight angle. The grain runs lengthwise on skirt steak, so you're cutting across the short dimension. Each slice should be about 1/4-inch thick. Fan the slices on a warm plate and spoon chimichurri generously over the top. Serve with a simple salad, roasted potatoes, or crusty bread to soak up the sauce.

Chef Notes

• The most important thing: Skirt steak must be cooked over the highest heat possible for the shortest time. It's a thin, fibrous cut that goes from perfect to overcooked in 60 seconds. Sear hard, rest well, slice thin against the grain.
• Cut the skirt steak into manageable pieces that fit your pan — about 6-8 inches long. Trying to cook a full-length skirt steak in a home pan leads to uneven cooking.
• Slice against the grain after resting. Skirt steak has very visible, long muscle fibers. Cutting against them shortens the fibers and makes each bite tender. Cutting with the grain makes it chewy.
• The chimichurri should be made at least 15 minutes before serving. The vinegar needs time to soften the raw garlic and the oil needs time to extract flavor from the herbs.
• Skirt steak is the traditional cut for Argentinian and Uruguayan asado. It's affordable, flavorful, and cooks in minutes — the perfect weeknight steak.

Common Substitutions

Ingredient	Substitution	Notes
Steak (ribeye, strip, etc.)	Flat iron or hanger steak	Both are flavorful and more affordable. Slice against the grain.
Bread	Gluten-free bread or lettuce wraps	GF bread varies by brand. Lettuce wraps for low-carb.
Potatoes	Sweet potatoes or cauliflower	Sweet potatoes add sweetness. Cauliflower for low-carb.
Red wine	Beef broth + 1 tsp red wine vinegar	Approximates the depth and acidity.
Olive oil	Avocado oil or grapeseed oil	Avocado oil has higher smoke point. Grapeseed is neutral.
Cilantro	Flat-leaf parsley + squeeze of lime	Parsley lacks the citrus note — lime helps bridge the gap.

What You're Practicing

Skirt steak teaches you about cooking thin cuts over extreme heat — a technique that requires confidence and timing. Unlike a thick ribeye where you have minutes of margin, skirt steak demands precision: 30 seconds too long and it's overcooked. This same skill applies to flank steak, hanger steak, and any thin cut. See Techniques for more on high-heat searing.

Slicing against the grain is one of the most important and most overlooked skills in meat cookery. The difference between cutting with and against the grain on skirt steak is the difference between tender and chewy. Once you train your eye to identify grain direction, you'll apply this to every cut of meat you cook. See Equipment for more on knife skills and cutting techniques.
