01 - Pat the chicken breasts completely dry with paper towels to ensure proper seasoning adhesion and crust formation.
02 - Combine smoked paprika, garlic powder, onion powder, dried thyme, dried oregano, cayenne pepper, black pepper, and kosher salt in a small bowl. Mix thoroughly to distribute spices evenly.
03 - Brush both sides of each chicken breast with olive oil or melted butter. Generously rub the spice mixture over the oiled chicken, pressing firmly to ensure the seasoning adheres properly.
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 a dark, crispy crust.
05 - Carefully place the seasoned chicken breasts in the hot skillet. Cook undisturbed for 4 to 5 minutes until a dark, charred crust forms. Flip and cook for an additional 4 to 5 minutes, or until the internal temperature reaches 165°F.
06 - Transfer the chicken from the skillet and let rest for 3 minutes to allow juices to redistribute. Slice if desired and serve immediately with lemon wedges.
