Creating Chimichurri Chicken is simple when you follow these steps:

1. Prepare the Chimichurri Sauce: In a mixing bowl, combine the chopped parsley, cilantro, minced garlic, red wine vinegar, olive oil, red pepper flakes, salt, black pepper, and lime juice. Stir well until all ingredients are combined.
2. Marinate the Chicken: Place the chicken breasts in a resealable plastic bag or a shallow dish. Pour half of the chimichurri sauce over the chicken, ensuring it’s well coated. Reserve the other half for serving.
3. Marinate: Seal the bag or cover the dish and refrigerate for at least 30 minutes. For best results, marinate for up to 2 hours.
4. Preheat the Grill or Oven: If grilling, preheat your grill to medium-high heat. If using an oven, preheat to 400°F (200°C).
5. Cook the Chicken: Remove the chicken from the marinade and discard the marinade. Grill the chicken for about 6-7 minutes on each side, or until fully cooked. If baking, place the chicken on a baking sheet and cook for 20-25 minutes or until the internal temperature reaches 165°F (75°C).
6. Rest the Chicken: Once cooked, remove the chicken from the grill or oven and let it rest for 5 minutes. This helps retain its juices.
7. Serve: Slice the chicken and drizzle the reserved chimichurri sauce over the top.

This step-by-step guide will ensure your Chimichurri Chicken turns out juicy, flavorful, and utterly delicious.
