01 - Pat the chicken breasts dry with paper towels to remove excess moisture.
02 - In a small bowl, combine the smoked paprika, garlic powder, onion powder, thyme, oregano, cayenne pepper, black pepper, and salt.
03 - Brush both sides of the chicken breasts with olive oil or melted butter, then rub generously with the spice mixture, pressing to adhere.
04 - Heat a large cast-iron skillet over medium-high heat until very hot, about 3 minutes.
05 - Add the chicken breasts and cook without moving for 4–5 minutes until a dark crust forms. Flip and cook another 4–5 minutes, or until the chicken reaches an internal temperature of 165°F.
06 - Remove from the skillet and let rest for 3 minutes before slicing. Serve with lemon wedges.
