Thaw the turkey one full day in advance.
Rub the turkey generously with kosher salt all over the outside and inside the cavities. Let it rest for about four hours (dry brine).
Preheat the oven to 350°F (175°C).
In a bowl, mix together the butter, thyme, rosemary, sage, and garlic.
Gently slide your hand under the skin to loosen it from the breast and thighs, creating pockets. Spread the herb butter between the skin and the meat.
Roughly chop the carrots, celery, onion, and garlic.
Stuff the turkey cavity with the chopped vegetables. Place additional vegetables and herbs in the bottom of the roasting pan. Pour in the chicken broth.
Roast the turkey for 2 hours.
Remove the turkey from the oven and baste it with the cooking juices. Cover loosely with aluminum foil and continue roasting for 1 hour 30 minutes, basting every 30 minutes.
The internal temperature of the turkey should reach 170°F when measured with a thermometer.
You can thicken the pan juices with cornstarch to make a gravy if desired.
Serve with mashed potatoes and cranberry sauce.
