Ingredients for argentinian skirt steak with chimichurri sauce

The vibrant green chimichurri and perfectly seared skirt steak transform simple ingredients into a restaurant-worthy masterpiece.

The skirt steak is the foundation—look for thin-cut, grass-fed from a trusted butcher or specialty market like Whole Foods or D'Artagnan. The thinner the cut, the more tender it cooks, and grass-fed delivers superior flavor. If you can't find skirt steak, flank steak works as a substitute, but slice it thinly against the grain. For the chimichurri, fresh parsley is non-negotiable—it's the heart of the sauce. Curly parsley has more flavor than flat-leaf, but either works. Buy it in small bunches and use it within 3 days for peak freshness.

No red wine vinegar? White wine vinegar or apple cider vinegar will work, though the flavor will differ slightly. The olive oil should be extra-virgin and fruity—avoid the cheap, bitter-tasting varieties. For heat, red pepper flakes are more versatile than cayenne, which can overpower. If you're missing cilantro, skip it entirely—the parsley alone carries the dish. The garlic should be fresh, never powdered. Toast the cumin seeds lightly in a dry pan before grinding for an intensified aroma. For the steak, Diamond Crystal kosher salt dissolves more easily than table salt, enhancing seasoning.

Store the chimichurri in an airtight container with a thin layer of olive oil on top to preserve freshness—it keeps for 3-4 days in the fridge. The steak should be cooked immediately or refrigerated uncovered for up to 24 hours to dry-brine. For leftovers, slice against the grain and reheat gently in a skillet. The chimichurri can also be frozen for up to 3 months—thaw in the fridge before using. Garnish with thinly sliced red onion just before serving to keep it crisp.

Step-by-step instructions for Argentinian skirt steak with chimichurri

This method delivers perfectly seared skirt steak paired with vibrant chimichurri—simple steps for maximum flavor impact.

In a food processor, combine the 1.5 cups fresh parsley leaves, 0.25 cup fresh cilantro leaves, 6 cloves garlic, 1 tsp red chili flakes, 1 tsp ground cumin, 1.5 tsp kosher salt, and 0.5 tsp cracked black peppercorns. Pulse until finely chopped but not puréed—you want texture, not a smooth paste.

With the processor running, slowly drizzle in the 0.5 cup extra-virgin olive oil and 0.25 cup red wine vinegar. Process until fully emulsified, scraping down the sides as needed. Transfer to a bowl and stir in the 1 tbsp lemon juice. The sauce should be bright green with herby aroma—this is your flavor foundation.

Pat the 1.5 lb Argentinian skirt steak completely dry with paper towels—moisture prevents proper searing. Season both sides generously with additional kosher salt. Let it sit at room temperature for 30 minutes while you prepare the grill or skillet.

Heat a cast-iron skillet over high heat until smoking hot. Add the steak and sear for 3-4 minutes per side, pressing down gently during the first minute to prevent curling. You'll know it's ready when deep brown crust forms and the internal temperature reaches 130-135°F for medium-rare.

Transfer the steak to a cutting board and let it rest for 10 minutes, loosely tented with foil. This crucial step allows juices to redistribute—cutting too soon will yield dry meat. While it rests, thinly slice the 1 whole red onion for garnish.

Slice the steak against the grain into ¼-inch strips. Plate immediately with a generous spoonful of chimichurri sauce and the sliced red onion. The vibrant green sauce should coat each bite, balancing the rich, smoky flavor of the perfectly seared steak.

Serve the skirt steak while still warm, ensuring each portion receives equal chimichurri distribution. The sauce should cling to the meat, adding bright herbal notes that complement the steak's natural beefy flavor. For best results, serve immediately with crusty bread or roasted potatoes.

This technique guarantees tender, flavorful steak with chimichurri that transforms ordinary grilling into a restaurant-quality experience. The key is proper searing paired with fresh, vibrant chimichurri—never overcook the steak or overprocess the sauce.

Troubleshooting your argentinian skirt steak with chimichurri sauce

Steak Overcooking

Skirt steak's thin cut means it cooks faster than thicker steaks—3-4 minutes per side max for medium-rare. The biggest mistake? Checking internal temp too late. Use a meat thermometer and pull at 130-135°F—it'll rise to 135-140°F while resting.

I've ruined many steaks by waiting for 140°F directly on the probe. 🔥

Chimichurri Texture Issues

If your chimichurri turns into a paste instead of a chunky sauce, you've overprocessed it. Pulse the food processor in short bursts—just until the herbs are finely chopped, not puréed. For extra texture, chop the parsley and garlic by hand first.

I once made the mistake of blending too long, ending up with a sad, soupy sauce instead of vibrant herby magic. ✨

Sauce Too Thin?

Chimichurri should coat the back of a spoon but maintain texture. If it's too thin, reduce the red wine vinegar by 1 tablespoon and add 1 extra tablespoon of olive oil.

The oil helps emulsify while keeping the sauce clingy. Pro tip: Let the sauce sit for 15 minutes before serving—flavors meld beautifully during this time.

Steak Sticking to Pan

Moisture is the enemy of perfect searing. Pat the steak completely dry with paper towels before seasoning. Heat your cast-iron skillet until smoking hot—this creates a nonstick crust. If it still sticks, your pan isn't hot enough.

I swear by Lodge cast iron for this—it retains heat like a dream and develops a natural nonstick patina over time.

Underseasoned Steak

Skirt steak absorbs salt well, but don't skimp. Use 1.5 teaspoons of Diamond Crystal kosher salt generously on both sides. For extra insurance, sprinkle a pinch of salt 10 minutes before cooking.

The key is even distribution—press the salt into the meat with your fingers. I've learned the hard way that "a little salt" won't cut it for this flavorful cut.

Chimichurri Separating

If your chimichurri separates, it's likely from too much vinegar or not enough emulsification. Stir in 1 extra tablespoon of olive oil and pulse briefly in the food processor to recombine.

For prevention, add the vinegar slowly while processing. The oil should bind everything together beautifully. This sauce is all about balance—too much acidity ruins the harmony.
