01 - Preheat oven to 425°F and position the rack in the center.
02 - Pat chicken thighs thoroughly dry with paper towels and place them in a large mixing bowl.
03 - Drizzle olive oil over the chicken thighs and toss until evenly coated on all sides.
04 - In a small bowl, combine kosher salt, black pepper, paprika, garlic powder, onion powder, dried thyme, and dried oregano. Mix until well blended.
05 - Sprinkle the seasoning blend generously over each chicken thigh, pressing gently to ensure full and even coverage.
06 - Place chicken thighs skin side up on a parchment paper- or foil-lined baking sheet, spacing them at least 1 inch apart.
07 - Bake for 35 to 40 minutes until the skin is deeply golden and crispy and an instant-read meat thermometer registers 165°F in the thickest portion of the meat.
08 - Remove from the oven and let rest for 5 minutes to allow juices to redistribute. Garnish with fresh parsley and serve alongside lemon wedges if desired.
