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. Add Old Bay seasoning, garlic powder, paprika, black pepper, and salt. Toss well until every thigh is evenly coated with the seasoning mixture.
04 - Arrange the seasoned thighs skin-side up on the prepared baking sheet, spacing them at least 1 inch apart to allow air circulation for crispy skin.
05 - Roast for 35 to 40 minutes, or until the skin is deeply golden brown and the internal temperature of the thickest part reaches 165°F when checked with an instant-read thermometer.
06 - Remove from the oven and let the chicken rest for 5 minutes. Garnish with chopped fresh parsley and serve hot with lemon wedges alongside.
