01 - Set the oven to 425°F and allow it to fully preheat.
02 - Line a large baking sheet with parchment paper or lightly grease with oil.
03 - In a large mixing bowl, combine halved potatoes, onion wedges, carrot coins, and smashed garlic. Drizzle with half the olive oil, then season with half of the salt, pepper, rosemary, thyme, and paprika. Toss well to coat evenly.
04 - Spread the seasoned vegetables in an even layer on the prepared baking sheet.
05 - Rub chicken thighs with the remaining olive oil, salt, pepper, rosemary, thyme, and paprika. Arrange chicken pieces skin-side up on top of the vegetables.
06 - Roast for 40 minutes until the chicken skin is golden and the potatoes are tender. If desired, broil for 2 to 3 minutes for extra-crispy skin.
07 - Remove the sheet from the oven and let the chicken rest for 3 to 5 minutes. Sprinkle with chopped fresh parsley before serving, if desired.
