01 - Set oven to 425°F and allow to fully preheat.
02 - Line a large baking sheet with parchment paper or lightly grease it.
03 - In a large bowl, toss halved potatoes, onion wedges, carrot coins, and smashed garlic with half the olive oil, salt, pepper, rosemary, thyme, and paprika until evenly coated.
04 - Spread vegetables in an even layer across the prepared baking sheet.
05 - Rub chicken thighs with the remaining olive oil, salt, pepper, rosemary, thyme, and paprika. Place chicken skin-side up atop the vegetables.
06 - Roast in the oven for 40 minutes, until chicken skin is golden and potatoes are fork-tender. For crispier skin, broil an additional 2 to 3 minutes as desired.
07 - Remove pan from oven and let rest 3 to 5 minutes. Finish with chopped fresh parsley before serving, if desired.
