01 - In a small mixing bowl, combine the rosemary, thyme, parsley, garlic, smoked paprika, sea salt, black pepper, cayenne pepper (if using), olive oil, and lemon zest. Stir until a thick, fragrant paste forms.
02 - Pat the chicken breasts thoroughly dry with paper towels. Rub the herb paste evenly over each breast, coating all sides. Let marinate at room temperature for at least 10 minutes, or refrigerate for up to 2 hours for deeper flavor.
03 - Heat your grill or grill pan to medium-high, approximately 400°F. Lightly oil the grates to prevent sticking.
04 - Place the chicken on the grill and cook for 6 to 8 minutes per side, until the internal temperature reaches 165°F and the exterior shows a well-charred crust.
05 - Transfer the chicken to a serving platter and tent loosely with aluminum foil. Allow it to rest for 5 minutes so the juices redistribute evenly.
06 - Plate the chicken alongside lemon wedges and finish with a sprinkle of freshly chopped parsley.
