How to Make It
Set a rack over a rimmed baking sheet. In a small bowl, mix the salt and pepper with all of the dried herbs and the lemon zest. Rub the herb salt all over the turkey cavity. Transfer the turkey to the baking sheet and refrigerate uncovered for 2 days.
Transfer the turkey to a clean rack set over a clean baking sheet; let stand at room temperature for 1 hour.
Preheat the oven to 400°. Stuff the turkey with the onion, celery and garlic. Tuck the wings under the breast and tie the legs together with kitchen twine. Brush the turkey all over with the butter. Put it in the oven and immediately reduce the temperature to 275°. Roast the turkey for about 3 hours and 15 minutes, basting occasionally, until an instant-read thermometer inserted in the inner thigh registers 165°. Cover the turkey with foil and let rest for 1 hour. Carve and serve.
