01 - In a small bowl, combine the minced garlic, chopped parsley, rosemary, thyme, olive oil, lemon juice, salt, and black pepper. Mix thoroughly until a uniform paste forms.
02 - Place the chicken breasts in a large resealable bag or shallow dish. Pour the marinade over the chicken, massaging it into each piece to ensure even, complete coating. Refrigerate for at least 15 minutes, or up to 2 hours for more pronounced flavor.
03 - Preheat the oven to 400°F or heat a grill to medium-high, ensuring the grate is clean and lightly oiled.
04 - Remove the chicken from the marinade, letting any excess drip off, and discard the remaining marinade. For oven baking, arrange the chicken in a single layer in a baking dish and bake for 25–30 minutes until the internal temperature reaches 165°F. For grilling, cook for 6–7 minutes per side until nicely charred and cooked through.
05 - Transfer the chicken to a cutting board and let it rest for 5 minutes so the juices redistribute. Garnish with fresh chopped parsley and serve alongside lemon wedges.
