01 - Preheat the oven to 425°F.
02 - Line a large baking sheet with parchment paper or lightly grease the surface.
03 - In a large mixing bowl, combine halved baby potatoes, red onion wedges, carrot slices, and smashed garlic. Toss with half of the olive oil, half of the salt, black pepper, rosemary, thyme, and paprika until vegetables are evenly coated.
04 - Spread the seasoned vegetables in a single layer on the prepared baking sheet.
05 - Rub chicken thighs with the remaining olive oil, remaining salt, pepper, rosemary, thyme, and paprika. Place the chicken thighs skin-side up on top of the vegetables.
06 - Roast in the preheated oven for 40 minutes, or until the chicken skin is golden brown and the potatoes are fork-tender.
07 - If desired, broil for 2 to 3 minutes to further crisp the chicken skin, watching closely to prevent burning.
08 - Remove from oven and let rest for 3 to 5 minutes. Garnish with chopped parsley before serving, if desired.
