Leave the turkey in its original wrapping and thaw it completely in the refrigerator.
Most turkeys come with the giblets and turkey neck packed inside the main body cavity. Some turkeys also include gravy mix packed inside the body. Look inside the thawed turkey from both ends and remove anything you find.
Preheat the oven to 325° Fahrenheit.
Rinse the thawed turkey with cold water and pat it dry with paper towels.
Rub the inside of the turkey with about ½ teaspoon salt.
If you are not going to stuff the turkey cut an onion or two into quarters and place inside the turkey while it roasts. When done, you can serve the onions or discard if you prefer.
If you want to stuff the turkey, do so now. Spoon the stuffing in lightly leaving room for it to swell. If you stuff it too tightly it will not cook thoroughly. Use no more than ¾ cup stuffing per pound of turkey. (You can bake left over stuffing in a covered casserole at 325° Fahrenheit for 30 to 45 minutes until heated through, or according to the package directions.)
Rub the turkey all over outside with vegetable oil and then with minced garlic. Place the turkey breast side up on a metal rack in a shallow roasting pan.
Mix together the seasonings you wish to use. (For an 8 to 10 pound turkey you would use 1 teaspoon basil, 1/2 teaspoon each sage and thyme, and about ¼ teaspoon salt.) Sprinkle this seasoning mixture all over the turkey.
