Put the turkey onto a wire rack on top of a baking sheet.
Brining
Mix together the brining ingredients then pat the turkey completely dry, inside and out. Rub the mixture generously over the skin of the turkey and inside the cavity.
Put the turkey bare into the fridge overnight and up to 18 hours to dry brine.
Roasting Turkey
An hour before you want to roast the turkey, take the brined turkey out of the fridge to rest on the counter.
Preheat oven to 325 degrees F.
Place the turkey into a roasting pan with a rack or prepped with aluminum foil, then pat the turkey dry of any moisture that may be lurking on the skin or in crevices.
Stuff the inside of the turkey with the aromatics until completely full. Truss the legs with butcher’s twine if they’re not already trussed.
Chop the herbs and lemon zest for the compound spread finely, then mix into the mayonnaise well.
Generously spread the compound mixture all over the dry skin of the turkey just before placing the turkey into the oven, every single part of the turkey. Use your fingers to pull the skin from the meat of the breasts and smooth some of the mixture under the skin. Tuck the wings under the turkey.
Roast the turkey at 325 degrees F, at about 15 minutes per pound or until a meat thermometer in the breast reads 160 degrees F.
Check the turkey about halfway through cooking, and once the skin gets golden brown cover the turkey breasts with aluminum foil to protect it from overcooking and the skin getting burned.
Let the turkey rest on the countertop for at least 25-30 minutes.
Reserve the drippings from the roasting pan to make a pan gravy.
