Line a large roasting pan with aluminum foil, then add the rack. Preheat the oven to 325°F.
Transfer the turkey to the prepared roasting pan, and loosen the skin around the turkey breasts. Carefully slide 2 tablespoons of butter pieces underneath the loosened skin.
8 to 10 pound turkey, ½ cup unsalted butter
Sprinkle the salt and pepper over the top of the turkey in an even layer. Place the citrus pieces into the cavity of the turkey until the entire cavity is full.
2 teaspoons salt, ½ teaspoons ground black pepper, 3 to 4 pieces citrus fruits
Tie the turkey legs together to ensure the citrus stays in place.
Cover the turkey with foil, and bake for 20-25 minutes per pound, about 3 to 4 hours depending on the size of the turkey.
During the last 30 to 45 minutes, remove the foil. If the skin looks like it’s beginning to dry, slowly pour melted butter over the turkey. Repeat as needed to keep the skin moist and flavorful.
The turkey is done when an instant read thermometer inserted into the thigh registers 180°F and 170°F in the breast. Remove the turkey from the oven, and allow it to rest for 20 minutes before carving.
