01 - Pat the chicken breasts dry with paper towels to ensure proper seasoning adhesion and crust formation.
02 - In a small bowl, combine the smoked paprika, garlic powder, onion powder, dried thyme, dried oregano, cayenne pepper, black pepper, and kosher salt. Mix thoroughly until evenly incorporated.
03 - Brush the chicken breasts with olive oil or melted butter on both sides, then rub the spice mixture generously over each piece, pressing firmly to adhere the spices to the meat surface.
04 - Place a large cast-iron skillet over medium-high heat and allow it to become very hot, approximately 3 minutes. Proper preheating is essential for achieving the characteristic blackened crust.
05 - Add the seasoned chicken breasts to the hot skillet and cook undisturbed for 4-5 minutes until a dark, caramelized crust forms. Flip and cook for an additional 4-5 minutes, or until the internal temperature reaches 165°F.
06 - Remove the chicken from the skillet and let rest for 3 minutes to allow juices to redistribute. Serve immediately with lemon wedges for squeezing over the finished dish.
