01 - Preheat oven to 425°F (220°C) to ensure a hot roasting environment.
02 - Line a large baking sheet with parchment paper or lightly grease to prevent sticking.
03 - In a large mixing bowl, combine halved baby potatoes, onion wedges, carrot coins, and smashed garlic. Toss with half of the olive oil, salt, pepper, rosemary, thyme, and paprika until evenly coated.
04 - Spread seasoned vegetables in an even layer on the prepared baking sheet for uniform cooking.
05 - Rub remaining olive oil, salt, pepper, rosemary, thyme, and paprika onto chicken thighs. Place chicken skin-side up on top of the vegetables.
06 - Roast in the center of the oven for 40 minutes, or until chicken skin is golden and potatoes are fork-tender. For crispier chicken skin, broil for an additional 2 to 3 minutes if desired.
07 - Remove tray from oven and allow to rest 3 to 5 minutes. Garnish with chopped parsley before serving, if desired.
