Grilled Chicken Thighs with Chimichurri Recipe

Of all the dishes that grace our grill during the warm summer months, there is one that my family requests time and time again, a recipe that has become synonymous with backyard gatherings and effortless entertaining: these Grilled Chicken Thighs with Chimichurri. The first time I made this, I was simply looking for a new way to jazz up our standard grilled chicken. I had no idea it would become an absolute sensation. The magic lies in the dual-purpose chimichurri sauce. It’s a vibrant, zesty, and herbaceous concoction that works first as a potent marinade, tenderizing the chicken and infusing it with layers of flavor, and then as a fresh, bright topping that cuts through the smoky char of the grill. I still remember my husband’s eyes widening after his first bite, followed by an enthusiastic, “You can make this again, anytime.” Now, the sight of a food processor on the counter and the scent of fresh cilantro and garlic filling the kitchen is a clear signal to everyone that we’re in for a treat. It’s a dish that feels special and gourmet yet is deceptively simple to prepare, making it my secret weapon for everything from a quick weeknight dinner to a weekend barbecue with friends. The juicy, succulent chicken thighs, perfectly cooked on the grill, combined with that punchy, unforgettable sauce, is a pairing that truly never gets old.

Ingredients

The beauty of this recipe lies in its use of fresh, simple ingredients that come together to create something truly spectacular. The list is divided into two parts: the components for the vibrant chimichurri sauce and the chicken itself. Let’s break down each element to understand its role in this culinary masterpiece.

For the Chimichurri Sauce:

• ▢ 1/2 cup fresh cilantro, fresh: Cilantro brings a bright, citrusy, and slightly peppery note that is essential to this sauce. When shopping, look for vibrant green leaves with no signs of yellowing or wilting. Ensure it’s thoroughly washed and dried before use to prevent a watery sauce.
• ▢ 1/2 cup fresh Italian parsley, chopped, fresh: Italian (or flat-leaf) parsley is the traditional backbone of chimichurri. It has a robust, clean, and peppery flavor that is less bitter than its curly counterpart. It provides the herbaceous body of the sauce.
• ▢ 1 tablespoon fresh oregano or 1 teaspoon dried: Fresh oregano is wonderfully pungent and aromatic. If you can’t find it, dried oregano is a perfectly acceptable substitute, as noted in the recipe. Remember the general rule: use about one-third the amount of dried herbs as you would fresh, as the flavor is more concentrated.
• ▢ 1 small shallot, peeled: A shallot offers a milder, more delicate, and sweeter flavor than a regular onion, with subtle hints of garlic. It adds aromatic depth without overpowering the fresh herbs.
• ▢ 2 cloves garlic, peeled: Garlic is non-negotiable for a powerful chimichurri. It provides a pungent, spicy kick that is fundamental to the sauce’s character. Feel free to adjust the amount based on your personal love for garlic!
• ▢ 1/2 jalapeno pepper, seeded: This is where you control the heat. Removing the seeds and membrane from the jalapeño will provide a mild, fruity pepper flavor with just a whisper of spice. If you prefer a spicier sauce, leave some of the seeds in.
• ▢ 1 tablespoon fresh lemon juice: The acidity from fresh lemon juice brightens all the other flavors, lifting the sauce and keeping it from feeling too heavy or oily. Always use freshly squeezed juice for the best, most vibrant taste.
• ▢ 1 tablespoon red wine vinegar: This is the traditional acidic component in Argentinian chimichurri. It adds a distinct, sharp tang that complements the richness of the olive oil and the grilled meat perfectly.
• ▢ 1/2 cup olive oil: Use a good quality extra virgin olive oil for this sauce. Its fruity, sometimes peppery flavor is a key component, not just a carrier for other ingredients. It emulsifies with the acids to create a luscious, well-balanced sauce.
• ▢ 1 teaspoon kosher salt: Kosher salt has larger flakes and a cleaner flavor than table salt. It’s crucial for seasoning the sauce and enhancing all the individual ingredient notes.
• ▢ Fresh ground pepper: Freshly ground black pepper adds a final touch of mild, woody spice that rounds out the flavor profile.

For the Chicken:

• ▢ 2 lbs boneless skinless chicken thighs: This is the star protein. Chicken thighs are the superior choice for grilling because their higher fat content ensures they remain incredibly juicy, tender, and flavorful, even when cooked over high heat. They are much more forgiving than chicken breasts, which can dry out easily. Look for thighs that are uniform in size for even cooking.

Instructions

Following these steps carefully will ensure your chicken is perfectly marinated, grilled to juicy perfection, and served with a stunningly flavorful sauce. We’ll break the process down into three main stages: creating the sauce, marinating the chicken, and grilling.

Step 1: Prepare the Flavor-Packed Chimichurri Sauce

This sauce is the heart of the dish, acting as both the marinade and the final topping. Using a food processor makes this step quick and easy.

1. Combine the Solids: In the bowl of your food processor, add the fresh cilantro, fresh Italian parsley, fresh oregano (if using), the peeled shallot, peeled garlic cloves, and the seeded jalapeño.
2. Add the Liquids and Seasonings: Pour the fresh lemon juice, red wine vinegar, high-quality olive oil, kosher salt, and a few grinds of fresh black pepper directly over the ingredients in the food processor.
3. Pulse to Perfection: Secure the lid and pulse the mixture 8-10 times. You are aiming for a finely chopped, slightly coarse texture, not a smooth, creamy puree. The sauce should still have some body and visible pieces of herbs and garlic. Over-processing can make the herbs bitter and the sauce too thin. Once you’ve reached the desired consistency, set the sauce aside.

Step 2: Marinate the Chicken

This crucial step infuses the chicken thighs with the incredible flavors of the chimichurri and helps to tenderize the meat.

1. Prepare the Chicken: Place the boneless, skinless chicken thighs in a large bowl, baking dish, or a large zip-top plastic bag. Season them lightly on all sides with an additional pinch of salt and pepper.
2. Apply the Marinade: Measure out approximately 1/4 cup of the freshly made chimichurri sauce and pour it over the chicken. Reserve the rest of the sauce for serving later. It’s very important to keep the serving sauce separate from the marinade that has touched raw chicken to avoid cross-contamination.
3. Coat and Marinate: Use tongs or your hands to turn and coat the chicken thighs completely, ensuring every piece is covered in the marinade.
4. Rest and Absorb: Cover the dish or seal the bag and place the chicken in the refrigerator to marinate. For a quick dinner, a 20-minute marinade will still impart great flavor. For a deeper, more developed taste, you can marinate for up to 24 hours. The longer it marinates, the more intense the flavor will be.

Step 3: Grill the Chicken to Juicy Perfection

The final step is grilling, which adds a smoky char that complements the zesty sauce.

1. Preheat the Grill: Heat your gas or charcoal grill to a steady medium-high heat, which is approximately 400-450°F (200-230°C). A hot grill is key to getting a good sear and preventing the chicken from sticking.
2. Warm the Chicken: While the grill is preheating, take the marinated chicken out of the refrigerator and let it sit on the counter for about 15-20 minutes. Allowing the chicken to come closer to room temperature helps it cook more evenly.
3. Clean and Oil the Grates: Once the grill is hot, use a grill brush to clean the grates thoroughly. Then, use a paper towel soaked in a high-smoke-point oil (like canola or avocado oil) and, holding it with long tongs, wipe the grates. This will create a non-stick surface for your chicken.
4. Grill the Chicken: Place the chicken thighs on the hot, oiled grates. Cook for approximately 5-6 minutes per side. Avoid moving the chicken too much during the first few minutes to allow beautiful grill marks to form.
5. Check for Doneness: The chicken is done when it is opaque all the way through and the internal temperature reaches 165°F (74°C) when checked with a meat thermometer inserted into the thickest part of the thigh. The juices should also run clear if pierced with a fork.
6. Rest the Chicken: Transfer the cooked chicken from the grill to a clean cutting board or plate. Let it rest for 5-10 minutes before slicing or serving. This allows the juices to redistribute throughout the meat, ensuring every bite is moist and tender.
7. Serve: Serve the grilled chicken thighs whole or sliced, with the reserved fresh chimichurri sauce spooned over the top or served on the side for dipping.

How to Serve

This Grilled Chicken with Chimichurri is incredibly versatile. While it’s fantastic on its own, you can easily build a complete, satisfying meal around it. Here are some delicious ways to serve it:

• Classic Argentinian Style:
  • Serve the chicken thighs whole or thickly sliced.
  • Spoon a generous amount of the fresh, reserved chimichurri sauce over the top.
  • Pair with grilled corn on the cob slathered in butter and a simple salad of mixed greens, tomatoes, and red onion with a light vinaigrette.
• As a Hearty Main Course:
  • With Potatoes: Serve alongside crispy roasted potatoes, creamy mashed potatoes, or grilled potato wedges.
  • With Rice: A bed of fluffy cilantro-lime rice or simple steamed white or brown rice is perfect for soaking up the extra sauce and juices.
  • With Grilled Vegetables: Create a colorful platter by grilling other vegetables alongside the chicken. Asparagus, bell peppers, zucchini, and red onion all take on a wonderful smoky flavor that pairs beautifully.
• In Bowls or Salads:
  • Chimichurri Chicken Bowl: Slice the grilled chicken and serve it over a base of quinoa or farro. Add toppings like black beans, corn salsa, avocado, and a dollop of sour cream or Greek yogurt.
  • Big Green Salad: Let the chicken cool slightly, slice it, and place it atop a bed of romaine lettuce or arugula. Add cherry tomatoes, cucumber, feta cheese, and use the chimichurri as your salad dressing.
• For Sandwiches and Tacos:
  • The Ultimate Chicken Sandwich: Slice the chicken and pile it high on a toasted ciabatta roll with provolone cheese, arugula, and an extra smear of chimichurri.
  • Flavorful Tacos: Dice the chicken and serve it in warm corn or flour tortillas. Top with cotija cheese, pickled red onions, and a drizzle of chimichurri.

Additional Tips

To ensure your dish is a runaway success every time, keep these five professional tips in mind:

1. Don’t Puree the Chimichurri: The key to authentic chimichurri is its texture. You want a finely chopped sauce, not a smooth, pesto-like puree. Pulsing the food processor, rather than letting it run continuously, gives you precise control. This ensures you can still identify the individual flecks of herbs and garlic, which provides a more rustic and appealing mouthfeel.
2. Use a Meat Thermometer for Perfect Chicken: While “juices run clear” is a good guideline, the only foolproof way to guarantee perfectly cooked, safe, and juicy chicken is by using an instant-read meat thermometer. Chicken thighs are cooked through and safe to eat when the internal temperature in the thickest part reaches 165°F (74°C). This eliminates any guesswork and prevents both undercooked and overcooked, dry chicken.
3. Let Your Chicken Rest After Grilling: This is one of the most important yet often skipped steps in cooking meat. When you pull the chicken off the hot grill, the juices are concentrated in the center. Letting it rest for 5-10 minutes allows those juices to relax and redistribute throughout the thigh, resulting in a significantly more tender and flavorful piece of meat.
4. Make the Chimichurri in Advance: The flavor of chimichurri actually deepens and improves as it sits. You can make the sauce up to 48 hours in advance and store it in an airtight container in the refrigerator. Just be sure to let it come to room temperature for about 30 minutes before serving to allow the olive oil to liquefy and the flavors to wake up.
5. Master Your Grill Heat: Don’t place your chicken on a grill that isn’t fully preheated. Medium-high heat is the sweet spot. If the grill is too hot, the outside will burn before the inside is cooked. If it’s not hot enough, you won’t get a good sear, the chicken may stick, and it will end up steaming rather than grilling. A consistent temperature is your best friend.

Frequently Asked Questions (FAQ)

1. Can I use chicken breasts instead of thighs for this recipe?
Yes, you absolutely can use boneless, skinless chicken breasts. However, since breasts are much leaner than thighs, you’ll need to adjust your cooking method to avoid drying them out. It’s best to pound the thicker end of the breast to create a more even thickness for uniform cooking. Marinate as directed, but watch the grill time closely. They will likely cook faster, perhaps 4-6 minutes per side, depending on thickness. Grill until the internal temperature reaches 165°F (74°C) and not a degree more.

2. What is the best way to store leftover chimichurri sauce?
Store any leftover chimichurri sauce (the portion that did not touch the raw chicken) in an airtight container, like a glass jar, in the refrigerator. To help preserve its vibrant green color and freshness, pour a thin layer of olive oil over the top of the sauce before sealing the container. This creates a barrier against air and oxidation. It will keep well in the fridge for up to a week.

3. My chimichurri came out tasting a little bitter. What went wrong?
Bitterness in chimichurri can usually be traced to one of two things. First, over-processing the herbs in the food processor can cause them to break down too much and release bitter compounds. Pulse just until chopped. Second, the culprit could be your olive oil. Some robust extra virgin olive oils have a very strong, peppery, and sometimes bitter finish, which can be amplified in a raw sauce. Try using a milder, fruitier olive oil for a smoother taste.

4. I don’t have an outdoor grill. Can I still make this recipe?
Definitely! You have a few great indoor options. A cast-iron grill pan on the stovetop is the best alternative, as it will give you similar grill marks and char. Alternatively, you can use a regular heavy-bottomed skillet (cast iron works best) over medium-high heat. You can also cook the chicken under your oven’s broiler. Place the chicken on a broiler pan and broil for 5-7 minutes per side, watching it carefully to prevent burning. With any indoor method, be sure to turn on your exhaust fan!

5. Is chimichurri the same as pesto? They look similar.
While they may look alike, they are very different sauces from different parts of the world. The primary difference is in the core ingredients. Classic Italian pesto is made with basil, pine nuts, Parmesan cheese, garlic, and olive oil, giving it a creamy, nutty, and cheesy flavor. Argentinian chimichurri is parsley and oregano-based, contains no nuts or cheese, and gets its tangy kick from red wine vinegar. Chimichurri is bright, acidic, and herbaceous, while pesto is rich, savory, and creamy.
