01 - In a medium bowl, whisk together olive oil, smoked paprika, thyme, rosemary, garlic, salt, pepper, lemon zest, and lemon juice until well combined.
02 - Pat chicken breasts dry with paper towels. Place them in a large zip-top bag or shallow dish.
03 - Pour marinade over the chicken, ensuring all pieces are well coated. Marinate for at least 15 minutes (up to 2 hours in the refrigerator for deeper flavor).
04 - Preheat grill or grill pan to medium-high heat. Lightly oil the grates.
05 - Remove chicken from marinade, letting excess drip off. Grill chicken for 6–8 minutes per side, or until internal temperature reaches 165°F and juices run clear.
06 - Transfer to a plate, cover loosely with foil, and let rest for 5 minutes.
07 - Slice, garnish with fresh herbs and lemon wedges if desired, and serve.
