Step 1

Preheat the oven to 450°. Rub the chicken with 1 tablespoon of the olive oil. Season the chicken inside and outside with 3 teaspoons of the salt and 1 teaspoon of the black pepper. Stuff the chicken with 2 onion wedges, the halved garlic head and thyme sprigs. Rub the outside of the chicken with the chopped thyme, paprika and onion powder. Set aside.

Step 2

Toss together the potatoes, carrots, remaining onion wedges, 1 tablespoon of the olive oil, 1/2 teaspoon of the salt and ½ teaspoon of the pepper in a 6-quart round Dutch oven. Pour in the chicken stock. Place the chicken, breast-side up, on top of the vegetables and cover the Dutch oven with the lid.

Step 3

Roast the chicken, covered, for 35 minutes. Uncover and continue roasting until a thermometer inserted in the thickest part of the thigh registers 165°, 20 to 25 minutes. Broil on high until the chicken begins to brown, 1 to 2 minutes. Remove from the oven and let chicken rest for 15 minutes.

Step 4

Serve the carved chicken with the roasted vegetables and pan drippings.
