Creating Grilled Lemon Herb Chicken Thighs is straightforward if you follow these clear steps:

1. Prepare the Marinade: In a bowl, whisk together the olive oil, lemon juice, lemon zest, minced garlic, rosemary, thyme, salt, pepper, and red pepper flakes until well combined.
2. Marinate the Chicken: Place chicken thighs in a large resealable bag or shallow dish. Pour the marinade over the chicken, ensuring each piece is coated. Seal the bag or cover the dish and refrigerate for at least 30 minutes to 2 hours for optimal flavor.
3. Preheat the Grill: Preheat your grill to medium-high heat (around 375-400°F or 190-200°C).
4. Grill the Chicken: Remove the chicken from the marinade, shaking off any excess. Place the chicken thighs skin-side down on the grill. Cook for 7-10 minutes, then flip and grill for another 7-10 minutes or until the internal temperature reaches 165°F (75°C).
5. Check for Doneness: Use a meat thermometer to check that the chicken thighs are fully cooked. If they need more time, close the grill lid and cook for an additional few minutes.
6. Rest the Chicken: Once cooked, remove the chicken from the grill and let it rest for about 5 minutes before serving. This helps the juices redistribute.
7. Garnish and Serve: Garnish with fresh parsley and additional lemon slices if desired. Serve the chicken warm with your favorite sides.

These steps make it easy to create succulent Grilled Lemon Herb Chicken Thighs that are sure to impress everyone at your table.
