01 - Preheat oven to 425°F.
02 - Line a large baking sheet with parchment paper or lightly grease with oil.
03 - In a large mixing bowl, combine halved potatoes, red onion wedges, carrot coins, and smashed garlic. Add half the olive oil, half the salt, black pepper, rosemary, thyme, and paprika. Toss until evenly coated.
04 - Spread the seasoned vegetables in a single, even layer on the prepared baking sheet.
05 - Rub chicken thighs with remaining olive oil, salt, pepper, rosemary, thyme, and paprika. Arrange chicken skin-side up on top of the vegetables.
06 - Roast in preheated oven for 40 minutes, until chicken skin is golden and potatoes are tender. For crispier chicken skin, broil for an additional 2 to 3 minutes if desired.
07 - Remove pan from oven and allow to rest for 3 to 5 minutes. Garnish with chopped fresh parsley before serving, if desired.
