Allow the turkey to come to room temperature by letting it sit out for 1 hour before roasting.
Remove the giblets from the cavity.
Preheat the oven to 325°F (160°C).
Pat the turkey dry with paper towels and season the cavity with kosher salt and fresh ground black pepper.
Stuff the cavity with the quartered onion, quartered lemon, and sprigs of rosemary, thyme, and sage.
Combine the softened butter, minced garlic, kosher salt, black pepper, chopped rosemary, and chopped thyme in a small bowl.
Rub the herb butter under the skin and over the turkey.
Place the onion, celery, and carrots in the roasting pan.
Roast the turkey until cooked through, using the time guidance given in the recipe.
Let the turkey rest for 20 to 30 minutes before carving.
