01 - Preheat the oven to 425°F (220°C).
02 - Line a large baking sheet with parchment paper or lightly grease it.
03 - In a large bowl, combine halved baby potatoes, red onion wedges, carrot coins, and smashed garlic. Toss with half the olive oil, 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 remaining olive oil, salt, black pepper, rosemary, thyme, and paprika. Place the chicken skin-side up on top of the vegetables.
06 - Roast for 40 minutes, or until chicken skin is golden and potatoes are fork-tender. For extra-crispy skin, broil for an additional 2 to 3 minutes if desired.
07 - Remove the pan from the oven and let rest for 3 to 5 minutes. Garnish with chopped parsley before serving, if desired.
