01 - In a small bowl, combine minced garlic, chopped parsley, rosemary, thyme, olive oil, lemon juice, salt, and black pepper. Mix thoroughly until a uniform paste forms.
02 - Place chicken breasts in a large resealable bag or shallow dish. Pour the marinade over the chicken, massaging the bag or turning each breast to ensure even, complete coating. Marinate at room temperature for at least 15 minutes, or refrigerate up to 2 hours for deeper flavor penetration.
03 - Preheat oven to 400°F or heat a grill to medium-high, ensuring the grate is clean and lightly oiled.
04 - Remove chicken from the marinade, allowing any excess to drip off. Discard the remaining marinade.
05 - For oven method: arrange chicken in a baking dish and bake 25–30 minutes until the internal temperature reaches 165°F. For grill method: cook 6–7 minutes per side until fully cooked through with appealing char marks.
06 - Transfer chicken to a cutting board and rest for 5 minutes to allow juices to redistribute. Garnish with fresh parsley and serve alongside lemon wedges.
