01 - Preheat oven to 425°F.
02 - Line a large baking sheet with parchment paper or grease lightly.
03 - Combine potatoes, red onion, carrots, and garlic in a large bowl. Toss with half the olive oil, half the salt, black pepper, rosemary, thyme, and paprika until vegetables are evenly coated.
04 - Spread 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 on top of vegetables.
06 - Roast for 40 minutes, or until chicken skin is golden and potatoes are fork-tender. For extra crispy skin, broil for 2 to 3 minutes if desired.
07 - Remove baking sheet from oven and let rest for 3 to 5 minutes. Garnish with chopped parsley before serving as desired.
