01 - Preheat the oven to 425°F. Line a rimmed baking sheet with parchment paper or aluminum foil for easy cleanup.
02 - Pat the chicken thighs thoroughly dry with paper towels and transfer them to a large mixing bowl.
03 - Drizzle the olive oil over the chicken. Add the Old Bay seasoning, garlic powder, paprika, black pepper, and salt. Toss everything together until each thigh is evenly and generously coated.
04 - Place the chicken thighs skin-side up on the prepared baking sheet, spacing them at least 1 inch apart to allow the skin to crisp properly.
05 - Roast for 35 to 40 minutes, until the skin is deeply golden brown and an instant-read thermometer inserted into the thickest part of the thigh registers 165°F.
06 - Remove the baking sheet from the oven and let the chicken rest for 5 minutes. Garnish with chopped fresh parsley and serve hot alongside the lemon wedges.
