01 - Preheat oven to 425°F. Line a baking sheet with parchment paper or aluminum foil.
02 - Pat chicken thighs thoroughly dry with paper towels to promote crispy skin development.
03 - In a small mixing bowl, combine smoked paprika, garlic powder, onion powder, dried thyme, dried oregano, cayenne pepper, ground black pepper, and kosher salt. Mix until evenly distributed.
04 - Coat chicken thighs with olive oil, then generously sprinkle the Cajun spice blend over all surfaces, pressing gently to ensure the seasoning adheres properly.
05 - Place seasoned chicken thighs skin-side up on the prepared baking sheet with adequate space between each piece.
06 - Roast in preheated oven for 30 to 35 minutes until the skin is crisp and the internal temperature reaches 165°F when measured at the thickest part.
07 - Remove from oven and allow to rest for 5 minutes. Top with fresh parsley and serve alongside lemon wedges.
