How long to cook dry brined turkey?
According to a highly rated recipe from Food Network for dry brined turkey:


  Put the oven rack in the lowest position; preheat the oven to 350 degrees F. Put the turkey breast-side up on a rack in a large roasting pan, tucking the wing tips under. Tie the drumsticks together with twine. Roast until the skin is golden brown and a thermometer inserted into the thigh registers 165 degrees F, about 15 minutes per pound. Transfer to a cutting board and let rest 30 minutes before carving. 


Keep in mind that there are a lot of variables. Your thermometer is your friend. If the turkey is stuffed, it could take as long as 7.5 hours.
