01 - Preheat oven to 425°F. Line a rimmed baking sheet with aluminum foil or parchment paper.
02 - Pat chicken thighs thoroughly dry with paper towels and transfer to a large mixing bowl.
03 - In a small bowl, combine kosher salt, black pepper, smoked paprika, garlic powder, onion powder, dried oregano, and dried thyme. Mix until evenly blended.
04 - Drizzle olive oil over the chicken thighs, then sprinkle the seasoning blend evenly over each piece. Toss and rub to coat thoroughly on all sides.
05 - Place chicken thighs skin-side up on the prepared baking sheet, spacing them at least 1 inch apart for even air circulation.
06 - Bake on the center rack for 35 to 40 minutes until the skin is deeply golden and crisp, juices run clear, and an instant-read thermometer inserted into the thickest part registers 165°F.
07 - For an even crispier finish, switch the oven to broil for the final 2 to 3 minutes, watching closely to prevent burning.
08 - Transfer chicken to a warm platter, garnish with chopped fresh parsley, and serve alongside lemon wedges.
