Step-by-Step Instructions

1. Make the Chimichurri Sauce: In a medium bowl, combine the chopped parsley, cilantro (if using), minced garlic, oregano, olive oil, red wine vinegar, lemon juice, red pepper flakes (if using), salt, and pepper. Stir well to combine. Let the sauce sit for at least 15 minutes at room temperature to allow the flavors to meld. Reserve about 1/4 cup of the sauce for serving.
2. Marinate the Chicken: Pat the chicken breasts completely dry with paper towels. This is essential for getting a good sear on the grill. In a shallow dish or large bowl, combine the chicken breasts with about 1/4 cup of the chimichurri sauce, ensuring both sides are well coated. Cover and refrigerate for at least 1 hour, or up to 4 hours for deeper flavor.
3. Fire Up the Grill: Preheat your grill to medium-high heat (around 400°F). For a charcoal grill, set up a two-zone fire with coals on one side for direct heat and a cooler indirect zone on the other. For a gas grill, preheat all burners, then turn one off to create an indirect cooking area. Clean and oil the grates to prevent sticking.
4. Grill the Chicken: Remove the chicken breasts from the marinade, letting any excess drip off. Season both sides with salt and pepper, and drizzle with olive oil. Place the chicken breasts on the direct heat side of the grill. Cook for 5-7 minutes per side until you get nice, dark grill marks. Move the chicken to the indirect heat side, close the lid, and cook for another 5-10 minutes until the internal temperature reaches 165°F. The chicken should feel firm but still slightly springy to the touch.
5. Rest and Serve: Remove the chicken from the grill and let it rest on a cutting board for 5-10 minutes. This allows the juices to redistribute, ensuring tender, juicy meat. Slice the chicken breasts against the grain and serve with a generous spoonful of the reserved fresh chimichurri sauce on top. Garnish with fresh lemon wedges and extra herbs if desired.

Tips for Chimichurri Chicken Perfection

• Use Fresh Herbs: Fresh parsley and oregano are essential for authentic chimichurri. Dried herbs won’t give you the same bright, vibrant flavor. If you can find flat-leaf (Italian) parsley, it has more flavor than curly parsley.
• Chop, Don’t Blend: Traditional chimichurri is chopped by hand, not blended in a food processor. Hand-chopping gives the sauce a rustic texture with distinct bits of herb and garlic. If you do use a food processor, pulse gently to avoid pureeing the herbs.
• Let the Sauce Rest: The chimichurri sauce needs time for the flavors to meld. Make it at least 15 minutes before serving, or even a few hours ahead. The longer it sits, the more flavorful it becomes.
• Don’t Overcook the Chicken: Chicken breasts can dry out quickly. Use an instant-read thermometer to check for doneness—165°F is the target. Remember that the chicken will continue to cook slightly as it rests, so you can pull it off at 160°F-162°F.
• Serve with Extra Sauce: Chimichurri is meant to be generous. Serve extra sauce on the side so everyone can add as much as they like. It’s also amazing on grilled vegetables, steak, or fish.

Delicious Variations

• Smoked Chimichurri Chicken: Smoke the chicken on a pellet grill or smoker at 225°F for 1 hour, then finish over high heat for a smoky flavor that pairs beautifully with the bright chimichurri.
• Spicy Chimichurri: Add 1 finely chopped jalapeño or serrano pepper to the sauce for an extra kick. You can also add a pinch of cayenne pepper for heat without the chunks.
• Cilantro Lime Chimichurri: Replace half the parsley with cilantro and add extra lime juice for a brighter, more citrus-forward version that’s perfect for summer.
• Mint Chimichurri: Add 1/4 cup of fresh mint to the sauce for a refreshing twist that’s especially delicious with grilled lamb or chicken.
• Shallot Chimichurri: Add 1 finely chopped shallot to the sauce for an extra layer of mild, sweet onion flavor that complements the garlic and herbs beautifully.

Storage and Reheating Instructions

Storage: Store leftover chicken in an airtight container in the refrigerator for up to 3-4 days. Store the chimichurri sauce separately in a small jar or container—it will keep for up to a week.

Reheating: The best way to reheat this chicken is on the grill or in the oven to restore that crispy exterior. Preheat your oven to 375°F and bake for 8-10 minutes, or reheat on the grill over medium heat for 3-4 minutes per side. You can also use an air fryer at 375°F for 5-6 minutes. Avoid microwaving, as it will make the chicken tough and dry.

Freezing: Cooked chicken freezes well for up to 2 months. Thaw in the refrigerator overnight and reheat as directed. The chimichurri sauce can also be frozen in ice cube trays for easy portioning.

Frequently Asked Questions (FAQ)

How long do I grill chicken breasts for this recipe?
On a medium-high grill, chicken breasts typically take about 15-20 minutes total, depending on thickness. You’ll sear them over direct heat for 5-7 minutes per side, then move to indirect heat for another 5-10 minutes. Always check the internal temperature—you’re aiming for 165°F in the thickest part of the breast.

Can I use this chimichurri sauce on other meats?
Absolutely! Chimichurri is incredibly versatile and is traditionally served with grilled beef, especially steak. It’s also fantastic on grilled pork, lamb, fish, shrimp, or even roasted vegetables. The bright, herbaceous flavor complements so many different foods.

What’s the difference between chimichurri and pesto?
Chimichurri is an Argentinean sauce made with parsley, garlic, oregano, olive oil, and vinegar. It’s tangy, herbaceous, and typically served with grilled meats. Pesto is an Italian sauce made with basil, pine nuts, Parmesan cheese, garlic, and olive oil. Pesto is creamier and nuttier, while chimichurri is brighter and more acidic.

Can I make chimichurri ahead of time?
Yes! Chimichurri is actually better when made ahead of time. The flavors continue to meld and develop as it sits. Make it up to 2-3 days in advance and store it in the refrigerator. Just bring it to room temperature before serving and give it a good stir.

What sides go well with chimichurri chicken?
This dish pairs beautifully with a variety of sides. Try it with grilled vegetables, rice and beans, roasted potatoes, a fresh green salad, or crusty bread to soak up the chimichurri sauce. For a complete Argentinean meal, serve it with grilled provolone cheese and a glass of Malbec.
