Pat the chicken dry with paper towels. Season generously inside and out with salt and pepper.
Place the chopped root vegetables, onion, and garlic in a large roasting pan. Drizzle with 1 tablespoon of olive oil and toss to coat.
Place the seasoned chicken on top of the vegetables in the roasting pan. Drizzle the chicken with the remaining 1 tablespoon of olive oil. Sprinkle with rosemary and thyme.
Roast for 1 hour and 15 minutes to 1 hour and 30 minutes, or until the chicken is golden brown and the juices run clear when pierced with a fork. The internal temperature of the thickest part of the thigh should reach 165°F (74°C).
Let the chicken rest for 10-15 minutes before carving. Serve with the roasted vegetables.
Notes
For crispier skin, you can rub a little butter under the chicken skin before roasting.
You can prepare the vegetables and place them in the roasting pan ahead of time.
This dish pairs well with a simple gravy made from the pan drippings.
