Season: Rub the softened butter or oil all over the chicken skin. Generously season with salt, pepper, and paprika. Stuff the lemon and some herbs inside the cavity.
Toss: In the bottom of your Dutch oven, toss the potatoes, carrots, and onions with a splash of oil and salt.
Assemble: Place the chicken directly on top of the vegetables. Tuck the garlic head and extra herbs into the sides.
Roast: Place the pot in the oven without the lid. Roast for 1 hour to 1 hour 15 minutes, or until the thickest part of the thigh reaches an internal temperature of 165°F (74°C).
Rest: Remove from the oven and let the chicken rest in the pot for 10–15 minutes before carving. This keeps the juices from running out.
