01 - In a mixing bowl, whisk together olive oil, lemon zest and juice, minced garlic, chopped parsley, thyme, rosemary, salt, and black pepper until well combined.
02 - Place chicken breasts in a resealable plastic bag or a shallow dish. Pour marinade over the chicken, turning each piece to fully coat. Seal and refrigerate for at least 20 minutes, up to 4 hours.
03 - Set oven to 400°F (200°C) to preheat.
04 - Heat an oven-safe skillet over medium-high. Add a small amount of olive oil if needed. Remove marinated chicken from bag, allowing excess marinade to drip off, and sear each breast for 2 to 3 minutes per side until golden brown.
05 - Transfer the skillet to the preheated oven. Roast for 15 to 18 minutes, or until the internal temperature reaches 165°F (74°C).
06 - Let chicken rest in the pan for 5 minutes before slicing. Garnish with additional parsley and lemon slices if desired, then serve while hot.
