01 - Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper or aluminum foil.
02 - Pat chicken thighs completely dry with paper towels to ensure crispy skin during roasting.
03 - In a small mixing bowl, combine smoked paprika, garlic powder, onion powder, thyme, oregano, cayenne pepper, black pepper, and kosher salt.
04 - Coat chicken thighs thoroughly with olive oil, then sprinkle the Cajun spice blend evenly over both sides, pressing gently to ensure seasoning adheres properly.
05 - Place seasoned chicken thighs skin-side up on the prepared baking sheet with adequate spacing between each piece.
06 - Roast for 30 to 35 minutes until the skin is crispy, the meat is cooked through, and the internal temperature reaches 165°F (75°C) when measured at the thickest part.
07 - Remove from oven and allow chicken to rest for 5 minutes. Garnish with chopped fresh parsley and serve with lemon wedges.
