01 - Preheat your oven to 425°F.
02 - Remove the chicken giblets if present and pat the chicken completely dry with paper towels.
03 - Season the cavity of the chicken with 1 teaspoon salt and ½ teaspoon pepper. Stuff with lemon halves, halved garlic head, and half of each herb.
04 - Rub the outside of the chicken with olive oil or melted butter. Sprinkle remaining salt, pepper, and paprika evenly over the skin.
05 - Tuck the wings under the chicken and tie the legs together with kitchen twine, if desired.
06 - Place onion quarters and remaining herbs in a roasting pan. Set the chicken breast-side up on top of the onions and herbs.
07 - Roast in the preheated oven for 1 hour 15 minutes, or until juices run clear when you cut between the leg and thigh, and a thermometer inserted into the thickest part of the thigh registers 165°F.
08 - Remove chicken from the oven and let rest for 10–15 minutes before carving to allow juices to redistribute.
09 - Carve and serve with pan juices and roasted onions.
