01 - Set oven to 425°F (220°C) to preheat.
02 - Line a large baking sheet with parchment paper or apply a light coating of oil.
03 - Combine halved potatoes, onion wedges, carrot coins, and smashed garlic in a mixing bowl. Toss with half the olive oil, half the salt, black pepper, rosemary, thyme, and paprika until evenly coated.
04 - Spread the seasoned vegetables in an even layer on the prepared baking sheet.
05 - Rub chicken thighs with the remaining olive oil, salt, black pepper, rosemary, thyme, and paprika. Place chicken thighs skin-side up atop the arranged vegetables.
06 - Roast for 40 minutes or until chicken skin is golden brown and potatoes are tender when pierced with a fork. For extra crispiness, 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 freshly chopped parsley before serving, if desired.
