01 - Preheat the oven to 425°F.
02 - In a large bowl, toss the chicken thighs with olive oil, salt, pepper, thyme, garlic powder, and paprika until evenly coated.
03 - In another bowl, combine carrots, potatoes, red onion, and bell pepper. Toss with olive oil, salt, pepper, and rosemary.
04 - Spread the vegetables in a single layer on a large baking sheet or roasting pan. Nestle the chicken thighs on top of the vegetables, skin-side up.
05 - Roast for 45–50 minutes, or until the chicken is golden and cooked through (internal temperature 165°F) and the vegetables are tender.
06 - If desired, broil for 2–3 minutes at the end for extra crispy chicken skin.
07 - Remove from the oven. Rest for 5 minutes. Garnish with fresh parsley and serve with lemon wedges.
