Argentinian Steak With Chimichurri Sauce Recipe: Herb-Packed Freshness That Elevates Every Bite

This Argentinian steak recipe transforms a simple cut of meat into a restaurant-worthy masterpiece with chimichurri sauce—bright, herby, and impossible to resist. 🔥 The secret lies in marinating the steak for at least 4 hours (overnight is even better), allowing the garlic, vinegar, and herbs to tenderize and infuse every bite.

I’ve perfected this method using skirt steak, which delivers bold flavor and perfect tenderness when cooked over high heat.

The chimichurri sauce is where the magic happens, blending fresh parsley, garlic, red wine vinegar, and olive oil into a vibrant green sauce that cuts through the richness of the steak. Unlike heavy creamy sauces, this fresh herb blend keeps the dish light yet deeply flavorful.

The key is chopping the parsley finely enough to create a smooth texture while maintaining that bright, herbaceous punch.

When you serve this dish, expect perfectly seared edges on the outside and tender, juicy meat inside, all paired with that zesty chimichurri that brightens every bite. The sauce doesn’t just sit on top—it soaks into the steak, enhancing its natural flavors without overpowering them.

This is the kind of meal that feels special yet stays true to its roots, bringing a taste of Buenos Aires to your kitchen.

For a complete Argentinian experience, serve with grilled provoleta (cheese sticks) or a simple side of grilled vegetables. The chimichurri works just as well on grilled chicken or shrimp, making this recipe versatile for any occasion. Let’s get cooking!

Ingredients for argentinian steak with chimichurri sauce

Fresh herbs and bold flavors transform simple skirt steak into an Argentinian masterpiece.

The skirt steak is the star—look for thin, well-marbled cuts at your butcher or Costco’s pre-trimmed packages. If you can't find skirt, flank steak works in a pinch, but slice against the grain for tenderness. The parsley needs to be fresh and vibrant—skip the dried stuff here. For the best chimichurri, I grab organic parsley from Whole Foods or my local farmers' market. The garlic should be plump and firm, not sprouting. Red wine vinegar matters too—avoid the sweetened kind found near balsamic; grab a bottle labeled 'dry' from the wine aisle.

No fresh parsley? Cilantro works in a bind, though the flavor will differ slightly. Running short on red wine vinegar? White wine vinegar or apple cider vinegar both work, but reduce the lemon juice to 1 tbsp to balance acidity. The olive oil should be light and fruity—none of that heavy, peppery stuff. For extra depth, add 1 tsp smoked paprika to the marinade. The cornstarch coating isn't mandatory, but it helps create that perfect crust when searing. If you're grilling outdoors, preheat your grill to high (450°F or higher)—this steak needs screaming heat to develop those charred edges.

Marinate the steak for at least 4 hours—overnight is ideal. Store it in a sealed container in the fridge. The chimichurri sauce keeps for up to 5 days in the fridge, but the parsley will darken. For longer storage, freeze the sauce in ice cube trays—thaw and stir before using. The cooked steak reheats beautifully—warm in a skillet over medium heat for 1-2 minutes per side. Leftovers? Slice thinly and use in tacos, sandwiches, or grain bowls within 3 days.

Step-by-step instructions for Argentinian steak with chimichurri

Master this iconic pairing with a bold, herb-forward chimichurri that brightens every bite of tender skirt steak.

Pat the 1.5 lb skirt steak completely dry with paper towels—this ensures a perfect sear. Trim any remaining fat to leave just a thin layer, which will render during cooking. Season both sides generously with 1.5 tbsp kosher salt and 1 tsp ground black pepper, pressing it into the meat so it adheres evenly. Let the steak sit at room temperature for 30 minutes before cooking. This step is non-negotiable; cold meat cooks unevenly and steaks lose precious moisture.

While the steak rests, make your cornstarch slurry by mixing 1 tbsp cornstarch with 1 tbsp grainy mustard in a small bowl. This mixture will create a subtle crust that locks in juices. Set it aside—you'll use it just before cooking. The mustard adds depth that complements the bright chimichurri perfectly.

Heat a cast-iron skillet over high heat until it's screaming hot—you should see a shimmer of smoke when you sprinkle a few drops of water. Add the steak and let it sear undisturbed for 3-4 minutes until a deep, golden-brown crust forms. Here's the thing—don't move it. Resist the urge to flip early; you'll know it's ready when the edges release easily from the pan.

Flip the steak and sear the other side for another 3-4 minutes. In the last minute, brush the cornstarch slurry evenly over both sides. This creates a delicate crust that holds up to the chimichurri's acidity. For medium-rare doneness, aim for an internal temperature of 130-135°F—use a meat thermometer for precision. Transfer the steak to a cutting board and let it rest for 10 minutes, tented loosely with foil. This resting period is crucial for redistributing juices.

While the steak rests, pulse 1.5 cups fresh flat-leaf parsley, 8 cloves garlic, 0.25 cup fresh oregano, and 0.5 tsp red pepper flakes in a food processor until finely chopped but not paste-like. Transfer the mixture to a bowl and whisk in 0.5 cup red wine vinegar, 2 tbsp lemon juice, and 1 cup extra-virgin olive oil. The sauce should be vibrant green with a loose, saucy consistency—like a fresh herb pesto.

Taste and adjust seasoning with additional kosher salt if needed. The chimichurri should be bright, herby, and slightly tangy—this balance is what makes it work with the rich steak. If it's too thick, whisk in 1-2 tbsp water to loosen it. This sauce is best made fresh; its vibrant flavors fade quickly once blended.

Slice the steak against the grain into ¼-inch thick strips for maximum tenderness. Arrange the slices on a platter and immediately drizzle with the chimichurri sauce. The acidity in the sauce cuts through the richness of the steak, creating a perfect balance of flavors. For an extra touch, garnish with additional chopped parsley and a sprinkle of red pepper flakes if you like heat.

Serve immediately with crusty bread or roasted potatoes to soak up the remaining sauce. The chimichurri should coat every bite, delivering layers of fresh herbs, bright acidity, and a touch of spice. This dish is all about contrast—juicy, tender steak paired with the vibrant, fresh chimichurri. Leftovers? Store the steak and sauce separately to keep the chimichurri fresh.

Storing and reheating this argentinian steak with chimichurri sauce

Steak Storage

Store raw skirt steak in an airtight container or sealed plastic bag in the fridge for up to 3 days. For longer storage, vacuum-seal the steak and freeze it for up to 6 months.

When freezing, label the bag with the date and thaw overnight in the fridge before marinating. Never thaw at room temperature—this promotes bacterial growth. 🥩

Chimichurri Shelf Life

Fresh chimichurri sauce stays vibrant in the fridge for 3-4 days when stored in an airtight container with a splash of olive oil on top to preserve freshness. For longer storage, freeze the sauce in ice cube trays—thaw and whisk before using.

The parsley will darken but the flavor remains bright. Avoid freezing with metal utensils to prevent oxidation.

Reheating Steak

Reheat sliced steak in a cast-iron skillet over medium heat for 1-2 minutes per side until warmed through. Add 1 tbsp olive oil to prevent sticking. For a quick option, microwave slices on 50% power for 30-45 seconds, then finish in the skillet to restore texture.

Never reheat past 165°F to avoid drying out the meat. 🔥

Reviving Chimichurri

If your chimichurri looks dull after refrigeration, whisk in 1 tbsp fresh lemon juice and 1 tbsp olive oil to revive its brightness. For extra freshness, stir in 1 tbsp finely chopped parsley just before serving.

Avoid reheating chimichurri—it loses its fresh, vibrant character when heated. Instead, serve it at room temperature alongside reheated steak.

Make-Ahead Tips

Marinate the steak overnight for maximum flavor penetration. Store the marinade separately in the fridge and combine with the steak just before cooking. For a complete make-ahead meal, prep the chimichurri ingredients (chopped herbs and garlic) in advance and store in airtight containers in the fridge.

Assemble the sauce fresh when ready to cook. 💡

Serving Leftovers

Use leftover steak in tacos, grain bowls, or sandwiches within 3 days. Chimichurri pairs perfectly with scrambled eggs or as a marinade for grilled chicken. For a quick lunch, slice steak thinly and toss with roasted potatoes and extra chimichurri.

Store leftovers in single-serving portions to maintain freshness and prevent sogginess. ✨
