Argentine Chicken Recipe: Chimichurri-Marinated Grill Masterpiece

This Argentine grilled chicken brings bold South American flavors to your table with a vibrant chimichurri marinade. The secret lies in a simple blend of fresh herbs, garlic, and vinegar that transforms ordinary chicken into a restaurant-quality masterpiece.

I perfected this method over years of backyard barbecues, learning that the marinade needs at least 2 hours to work its magic. The high-heat grilling creates a beautiful char while keeping the meat incredibly juicy inside.

You’ll achieve tender, flavorful chicken with that signature smoky aroma that defines Argentine asado. The chimichurri adds a bright, herby punch that cuts through the richness of the grilled meat.

Serve with grilled vegetables or crusty bread to soak up every drop of the marinade. This dish delivers authentic taste without complicated techniques.

Ingredients for Argentine Chicken

A handful of fresh ingredients plus bold spices create this vibrant dish with authentic flavor.

The chicken thighs are non-negotiable—bone-in, skin-on gives the best char and stays juicy. I grab mine from Whole Foods or a local butcher for quality. For herbs, fresh parsley and cilantro are key; look for bright, perky bunches (avoid anything wilted). The olive oil should be something you’d drizzle on bread—California Olive Ranch is a solid grocery store pick.

No fresh herbs? Dried parsley and cilantro at one-third the amount works in a pinch, but fresh is ideal. Swap red wine vinegar for apple cider vinegar if needed. Out of shallots? Red onion is a fine substitute. For heat, cayenne pepper can replace the red pepper flakes—just use half the amount. The chimichurri needs that 2-hour marinade time to develop flavor, so plan ahead.

Chimichurri keeps in the fridge for 3-4 days in a sealed jar—perfect for leftovers. The chicken is best served fresh but reheats okay (microwave with a damp paper towel to prevent drying). Store raw marinated chicken in the fridge for up to 24 hours before cooking.

Step-by-Step Instructions for Chimichurri-Marinated Chicken

Here’s the method I’ve perfected for vibrant, herb-packed chicken that grills up beautifully.

Step 1: Prepare the Chimichurri Marinade

In a food processor or blender, combine the 1.5 cups fresh parsley, 0.75 cup fresh cilantro, 6 cloves garlic cloves, 1 whole shallot, 1 tbsp dried oregano, 1 tsp red pepper flakes, 1.5 tbsp kosher salt, and 1 tsp black pepper.

Pulse until finely chopped. With the machine running, slowly drizzle in 0.75 cup extra-virgin olive oil followed by 0.5 cup red wine vinegar and the zest and juice from 1 whole lemon. Process until smooth but still slightly textured. This vibrant green sauce should smell incredibly fresh and herbal.

Step 2: Marinate the Chicken

Place the 2.5 lb chicken thighs in a large resealable plastic bag or shallow dish. Pour the chimichurri marinade over the chicken, ensuring all pieces are thoroughly coated. Massage the marinade into the meat for even distribution.

Let it marinate at room temperature for 30 minutes, or for deeper flavor, refrigerate for 4-12 hours. The acidity in the vinegar and lemon will begin to tenderize the meat while the herbs infuse it with authentic Argentine flavor. Don’t exceed 12 hours of marinating, as the acid can start to break down the meat texture too much.

Step 3: Grill to Perfection

Preheat your grill to medium-high heat. Remove the chicken from the marinade (reserve any leftover marinade for basting) and let excess drip off. The chicken should sizzle immediately when it hits the grates.

Grill the chicken for 6-8 minutes per side, basting occasionally with reserved marinade. You’ll know it’s ready to flip when the edges start to turn opaque white and the skin releases easily from the grates. Cook until the internal temperature reaches 165°F and the skin is beautifully charred.

Step 4: Rest and Serve

Transfer the grilled chicken to a clean platter and let it rest for 5-10 minutes. This allows the juices to redistribute throughout the meat, ensuring each bite is moist and flavorful. The chicken should have a beautiful char with bright green flecks from the chimichurri clinging to the surface.

Serve immediately with additional chimichurri sauce spooned over the top. The combination of smoky grill flavors and fresh herbal notes makes this dish truly special. I recommend pairing it with crusty bread to soak up all the delicious juices and sauce.

Pro Cooking Tips for Great argentine chicken

Marinade Mastery

For the most vibrant chimichurri, pulse herbs in a food processor just until finely chopped—not puréed. I use my Cuisinart Mini-Prep for perfect texture. The key is adding olive oil slowly while pulsing to create an emulsion. 💡

Grill Temperature Control

Maintain medium-high heat (about 375-400°F) for that perfect char. I check my Weber grill with an infrared thermometer. Too low and you’ll steam the chicken; too high and the herbs will burn before the meat cooks through.

Basting Technique

Reserve ¼ cup marinade for basting, but stop basting during the final 2 minutes of grilling. This prevents raw marinade from sticking to the surface. Use a long-handled basting brush to avoid flare-ups from dripping oil.

Chicken Placement

Arrange thighs skin-side down first, leaving space between pieces for proper airflow. On my 22-inch Weber kettle, I can fit 8 thighs comfortably. Rotate pieces halfway through cooking for even charring.

Resting Essential

Never skip the 5-10 minute rest—this lets juices redistribute. Tent loosely with foil to keep warm. The internal temp will rise 5-10°F during resting, so pull at 160°F for perfect doneness. 🔥

Charcoal Choice

For authentic flavor, use natural lump charcoal like Jealous Devil. Avoid briquettes with additives. I light my chimney starter 20 minutes before grilling to ensure even, hot coals.
