Argentinian Chicken Recipe: Chimichurri-Kissed Grill Perfection

This Argentinian chicken recipe delivers the bold flavors of pollo a la parrilla—juicy, perfectly grilled chicken kissed with fresh chimichurri that transforms a simple meal into a restaurant-worthy experience.

The secret lies in marinating the chicken overnight in a blend of garlic, oregano, and red wine vinegar, ensuring tender meat with a crispy exterior that sizzles on the grill.

I developed this recipe after years of perfecting the balance between smoky char and vibrant herbaceousness, a technique I learned from Buenos Aires asados.

What sets this dish apart is the chimichurri sauce, a bright green herb blend that cuts through the richness of the grilled chicken while adding layers of freshness.

Unlike traditional marinades, this version uses olive oil and red wine vinegar to create a sauce that’s equally effective as a finishing touch or a dipping companion.

The recipe also includes a side of puré de papa—creamy mashed potatoes infused with garlic and butter—to round out the meal with comfort and texture.

By the time you serve this dish, you’ll have golden-brown chicken with a smoky crust, tender meat that falls apart easily, and chimichurri that adds a burst of parsley, garlic, and vinegar with every bite.

The combination of grilled chicken, vibrant chimichurri, and creamy potatoes creates a harmonious balance of flavors and textures that feels both rustic and refined. This is the kind of meal that turns weeknight dinners into a taste of Argentina.

Pair it with a crisp white wine or a cold cerveza for the full experience. Whether you’re grilling for a crowd or treating yourself to a special meal, this recipe delivers foolproof results every time. Let’s get cooking!

Ingredients for argentinian chicken

Argentinian flavors start with these fresh ingredients for perfectly grilled chicken and vibrant chimichurri.

The chicken thighs are non-negotiable here—bone-in, skin-on delivers the most flavor, but boneless works if you prefer. Look for organic or free-range at Whole Foods or your local butcher for the best marbling. The parsley needs to be bright green and fresh—avoid wilting leaves. For the chimichurri, Penzeys or local Latin markets often carry the best quality herbs. The potatoes should be firm and unblemished—Russets hold up best to boiling and mashing.

No red wine vinegar? Apple cider vinegar or white wine vinegar work in a pinch, though the flavor profile shifts slightly. Mexican oregano is ideal, but regular dried oregano at half the amount gets you close. The olive oil should be lightly fruity—avoid the bitter varieties. For the mashed potatoes, butter and cream must be cold when adding to avoid a gluey texture. The red pepper flakes are optional but add a subtle heat that complements the smoky chicken perfectly.

Chimichurri keeps best in a sealed jar with a thin layer of olive oil on top—good for 5-7 days in the fridge. The marinated chicken can be refrigerated for up to 24 hours before grilling. Leftover mashed potatoes reheat beautifully—just add a splash of milk or cream and warm through. Portion the chimichurri into small containers for easy dipping or drizzling over future meals.

Step-by-step instructions for chimichurri-kissed grilled chicken

Here’s the method to achieve perfectly grilled chicken thighs with vibrant chimichurri and crispy russet potatoes.

In a food processor, combine the 1 cup fresh flat-leaf parsley, 6 cloves garlic cloves, 1 tablespoon dried oregano, 1.5 teaspoons kosher salt, and 0.25 teaspoon red pepper flakes. Pulse until finely chopped but not completely puréed—you want texture. With the processor running, slowly drizzle in the 0.5 cup red wine vinegar and 0.75 cup extra-virgin olive oil until fully incorporated. The sauce should be bright green and slightly thick, like a coarse pesto. Taste and adjust seasoning if needed—this is your flavor foundation.

Transfer the chimichurri to a small bowl and set aside. The acidity from the vinegar will tenderize the chicken as it marinates, while the herbs infuse deep flavor. This sauce is best made fresh, so prepare it just before grilling to preserve its vibrant color and sharpness.

Pat the 1.5 lb boneless, skinless chicken thighs dry with paper towels—this ensures a better sear. Season both sides generously with 0.5 teaspoon ground black pepper, then rub the chimichurri evenly over the entire surface, pressing it into the meat. Place the chicken on a plate and let it marinate for at least 30 minutes at room temperature. This step guarantees tender, flavorful meat with a perfect crust.

While the chicken marinates, preheat your grill to medium-high heat, around 400°F, with the lid closed. Clean and oil the grates thoroughly to prevent sticking—this is especially important for juicy chicken thighs. The high heat will create those coveted grill marks while keeping the interior moist.

Place the marinated chicken thighs on the preheated grill, skin-side down if applicable. Grill for 5-6 minutes per side until the internal temperature reaches 165°F and the surface develops deep grill marks. You’ll know it’s ready when the edges are slightly charred and the juices run clear when pierced with a meat thermometer. Avoid pressing the meat with a spatula—this squeezes out precious juices.

During the last minute of grilling, brush any remaining chimichurri over the chicken to enhance flavor and add a fresh herb finish. Transfer the cooked chicken to a cutting board, tent loosely with foil, and let it rest for 5 minutes before serving. This resting period allows the juices to redistribute, ensuring each bite is succulent and flavorful.

While the chicken rests, boil the 2 lbs russet potatoes in salted water until tender, about 15-20 minutes. Drain well and return them to the pot. Add the 0.5 cup unsalted butter, 0.25 cup heavy cream, 1 tablespoon fresh lemon juice, and 0.5 teaspoon ground black pepper. Toss gently until the potatoes are coated in a creamy, garlicky sauce. The butter and cream create a velvety texture that balances the bold chimichurri flavors.

For extra depth, sprinkle with additional chopped parsley and a pinch of red pepper flakes if you like a bit of heat. Serve the potatoes immediately alongside the sliced chicken, drizzled with any remaining chimichurri from the bowl. The contrast of crispy, tender chicken with creamy potatoes makes this a complete, satisfying meal.

Regional styles of this argentinian chicken

Buenos Aires Asado Style

In Buenos Aires, grilled chicken—called pollo a la parrilla—is traditionally cooked over wood or charcoal fires during asados, or barbecues.

The key difference here is the marinade: instead of chimichurri, many Argentinian grill masters use a simple blend of olive oil, garlic, oregano, and red wine vinegar directly on the chicken.

I’ve adapted this by marinating the chicken in chimichurri for at least 4 hours (or overnight) to mimic the slow, smoky infusion of a traditional asado. 🌶️

For an authentic touch, use quebracho wood if grilling with wood chips—it’s the preferred fuel in Argentina for its mild, slightly sweet smoke. If you don’t have access, hickory or pecan chips work well as substitutes.

Serve the chicken family-style, piled high on a platter with chimichurri drizzled generously over the top, just like at a Buenos Aires parrilla.

Patagonia-Inspired Twist

In the southern regions of Patagonia, where winds are fierce and winters are long, chicken is often grilled over open flames with a heavy emphasis on garlic and smoked paprika. For a Patagonian-inspired version, add 1 teaspoon smoked paprika and 1 minced shallot to your chimichurri base.

The smoky depth pairs beautifully with the bright herbs, creating a flavor profile that’s both rustic and complex. 🔥

Serve this version with grilled zucchini and bell peppers instead of potatoes—a nod to the fresh, hearty vegetables grown in Patagonia’s fertile valleys. The high-altitude climate means vegetables here are often sweeter and more vibrant, so take advantage of their natural flavors by grilling them alongside the chicken.

Cordoba-Style Chimichurri

Cordoba, in the heart of Argentina, is famous for its thicker, oilier chimichurri, which is often used as both a marinade and a sauce.

For a Cordoba-style twist, reduce the red wine vinegar to ¼ cup and increase the olive oil to 1 cup, then blend in 2 tablespoons of fresh oregano (not dried) for an extra herbal punch. This richer chimichurri clings beautifully to the chicken, creating a luxurious, herb-forward bite. 💛

Pair this with grilled corn on the cob and a side of ensalada rusa (Russian salad), a classic Argentinian dish made with potatoes, carrots, peas, and a tangy mayo-based dressing. The contrast of the creamy salad with the smoky, herby chicken is a match made in Cordoba.

Urban Buenos Aires Shortcut

For city dwellers in Buenos Aires, where grills aren’t always available, chicken is often pan-fried in a cast-iron skillet with chimichurri. Heat 2 tablespoons of olive oil in a Lodge cast-iron skillet over medium-high heat, then sear the marinated chicken for 4-5 minutes per side until golden and crispy.

Finish with a splash of white wine (about 2 tablespoons) to deglaze the pan, then spoon the sauce over the chicken. This method delivers the same bold flavors without the need for a grill. 🍳

Serve the pan-fried chicken with quick-pickled red onions (thinly sliced onions soaked in vinegar, sugar, and salt for 15 minutes) to cut through the richness. This urban adaptation is perfect for weeknight dinners but still feels like a taste of Argentina.
