01 - In a small mixing bowl, combine the rosemary, thyme, parsley, minced garlic, smoked paprika, sea salt, black pepper, cayenne (if using), olive oil, and lemon zest. Stir thoroughly until a thick, fragrant paste forms.
02 - Pat the chicken breasts 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, ensuring the grates are clean and lightly oiled 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 develops a nicely charred crust.
05 - Transfer the grilled chicken to a platter, cover loosely with aluminum foil, and let rest for 5 minutes to allow the juices to redistribute.
06 - Serve the chicken with lemon wedges alongside and a generous sprinkle of fresh chopped parsley.
