01 - Preheat oven to 425°F. Line a baking sheet with parchment paper or aluminum foil.
02 - Pat chicken thighs dry thoroughly with paper towels to ensure crispy skin during roasting.
03 - In a small bowl, combine smoked paprika, garlic powder, onion powder, dried thyme, dried oregano, cayenne pepper, black pepper, and kosher salt.
04 - Coat chicken thighs evenly with olive oil, then generously season both sides with the Cajun spice blend, pressing gently to ensure proper adhesion.
05 - Position chicken thighs skin-side up on the prepared baking sheet with adequate spacing between pieces for air circulation.
06 - Roast for 30 to 35 minutes until skin achieves crispness, chicken is fully cooked through, and internal temperature registers 165°F when measured at the thickest part.
07 - Remove from oven and allow to rest for 5 minutes. Garnish with fresh parsley and serve with lemon wedges.
