01 - Pat the chicken breasts dry with paper towels to ensure proper seasoning adhesion.
02 - In a small bowl, combine the smoked paprika, garlic powder, onion powder, thyme, oregano, cayenne, black pepper, and salt until well blended.
03 - Brush the chicken breasts with olive oil or melted butter on both sides, then rub the spice mixture generously over each breast, pressing firmly to adhere.
04 - Heat a large cast-iron skillet over medium-high heat until very hot, approximately 3 minutes.
05 - Add the chicken breasts to the hot skillet and cook undisturbed for 4-5 minutes until a dark, charred crust forms. Flip and cook for another 4-5 minutes, or until the internal temperature reaches 165°F.
06 - Remove from the skillet and let rest for 3 minutes to allow juices to redistribute. Slice and serve with lemon wedges.
