Follow these simple steps to create your Chimichurri Chicken Thighs:

1. Prepare the Chimichurri Sauce: In a bowl, combine the chopped parsley, olive oil, red wine vinegar, minced garlic, red pepper flakes, salt, black pepper, and lemon juice. Mix well and set aside.
2. Marinate the Chicken: Place the chicken thighs in a large zip-top bag or a shallow dish. Pour half of the chimichurri sauce over the chicken, ensuring they are well coated. Reserve the remaining sauce for serving.
3. Chill: Seal the bag or cover the dish, then refrigerate for at least 30 minutes. For best results, marinate for a few hours or overnight.
4. Preheat the Oven: When ready to cook, preheat your oven to 400°F (200°C).
5. Prepare the Chicken for Baking: Remove the chicken from the marinade and place it skin-side up on a baking sheet lined with parchment paper.
6. Bake the Chicken: Bake in the preheated oven for 25-30 minutes, or until the chicken reaches an internal temperature of 165°F (75°C) and the skin is crispy and golden brown.
7. Rest the Chicken: Remove from the oven and let the chicken rest for 5 minutes before serving.
8. Serve: Drizzle with the reserved chimichurri sauce and enjoy!
