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 until evenly blended.
03 - Brush olive oil or melted butter over both sides of each chicken breast. Generously apply the spice mixture, pressing firmly to ensure the rub adheres to the surface.
04 - Heat a large cast-iron skillet over medium-high heat for approximately 3 minutes until the pan is thoroughly hot and ready for searing.
05 - Place chicken breasts in the hot skillet. Cook undisturbed for 4-5 minutes until a dark, crusty exterior forms. Flip and cook an additional 4-5 minutes until the internal temperature reaches 165°F.
06 - Remove chicken from the skillet and allow to rest for 3 minutes to let juices redistribute. Slice and serve immediately with lemon wedges.
