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 the olive oil over the chicken thighs and toss until every piece is evenly coated.
04 - In a small bowl, combine the kosher salt, black pepper, paprika, garlic powder, onion powder, dried thyme, and dried oregano. Sprinkle the seasoning blend over the chicken, tossing to ensure full and even coverage on all sides.
05 - Place the seasoned chicken thighs skin side up on the prepared baking sheet, spacing them apart so air can circulate between each piece.
06 - Bake for 35 to 40 minutes, or until the skin is deeply golden and crisp and a meat thermometer inserted into the thickest portion registers 165°F (74°C).
07 - Remove the baking sheet from the oven and let the chicken rest for 5 minutes. Garnish with chopped fresh parsley and serve alongside lemon wedges if desired.
