01 - Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper or aluminum foil and set aside.
02 - Pat the 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 each piece is evenly coated.
04 - In a small bowl, combine kosher salt, black pepper, paprika, garlic powder, onion powder, dried thyme, and dried oregano. Sprinkle the seasoning blend over the chicken, tossing to ensure all surfaces are well covered.
05 - Place the seasoned chicken thighs skin side up on the prepared baking sheet, spacing them apart to allow even roasting.
06 - Bake for 35 to 40 minutes until the skin is golden and crispy and an instant-read meat thermometer registers 165°F (74°C) in the thickest part of the thigh.
07 - Remove from the oven and let the chicken rest for 5 minutes. Garnish with fresh chopped parsley and serve alongside lemon wedges if desired.
