01 - Set the oven to 425°F and allow it to fully preheat.
02 - Pat the chicken thighs dry with paper towels and transfer them to 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, mixing thoroughly.
05 - Sprinkle the seasoning blend over the chicken thighs, turning and tossing to ensure complete and even coverage on all sides.
06 - Place the seasoned chicken thighs skin side up on a baking sheet lined with parchment paper or aluminum foil, spacing them apart for even roasting.
07 - Roast in the oven for 35 to 40 minutes until the skin is deeply golden and crisp, and a meat thermometer inserted into the thickest part of a thigh registers 165°F.
08 - Remove the baking sheet from the oven and let the chicken rest for 5 minutes. Garnish with fresh chopped parsley and serve alongside lemon wedges if desired.
