01 - Preheat the oven to 325°F. Remove the turkey giblets and pat the turkey dry with paper towels.
02 - In a bowl, combine softened butter, salt, pepper, paprika, dried thyme, lemon zest, and chopped parsley.
03 - Loosen the turkey skin over the breast and legs. Spread half the butter mixture under the skin and rub the remaining butter evenly over the turkey surface.
04 - Fill the cavity with quartered onion, lemon halves, halved garlic head, and fresh rosemary, thyme, and sage sprigs.
05 - Arrange carrots, celery, and onion wedges in the bottom of a large roasting pan. Place a roasting rack over the vegetables and position the turkey breast-side up on the rack.
06 - Pour chicken broth into the bottom of the pan. Tie the turkey legs together with kitchen twine and tuck the wings under the body to ensure even cooking.
07 - Roast in the preheated oven. Baste with pan juices every 45 minutes. If the skin browns too quickly, loosely tent with foil to prevent burning.
08 - Continue roasting until a meat thermometer inserted into the thickest part of the thigh reads 165°F, approximately 2.5 to 3.5 hours.
09 - Transfer the turkey to a cutting board, cover loosely with foil, and let rest for 30 minutes to allow juices to redistribute.
