01 - Preheat oven to 425°F. Line a baking sheet with parchment paper or aluminum foil for easy cleanup.
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. Add Old Bay seasoning, garlic powder, paprika, black pepper, and kosher salt. Toss well until every piece is evenly coated.
04 - Place the seasoned thighs skin-side up on the prepared baking sheet, spacing them at least 1 inch apart to allow the skin to crisp.
05 - Roast for 35 to 40 minutes, or until the skin is deeply golden brown and the internal temperature at the thickest part reads 165°F on an instant-read thermometer.
06 - Remove the baking sheet from the oven and let the chicken rest for 5 minutes. Garnish with chopped fresh parsley and serve hot with lemon wedges alongside.
