It’s important that you use a roasting rack so the heat in the oven can circulate around the entire turkey.
Don’t worry about seasoning your turkey yet — seasoning won’t stick to a frozen turkey. You can season the turkey later after it thaws for a couple of hours in the oven.
If the temperature is lower than 100–125 °F (38–52 °C), let the turkey continue to roast and check on it periodically until it’s up to temperature.
You can also use other kinds of seasonings, like rosemary, thyme, and sage.
8–12 pounds (3. 6–5. 4 kg): roast for 1. 5-2 more hours. 12–14 pounds (5. 4–6. 4 kg): roast for 2-3 more hours. 14–20 pounds (6. 4–9. 1 kg): roast for 3-4 more hours. 20–24 pounds (9. 1–10. 9 kg): roast for 4-5 more hours.
Check the center of the turkey with the thermometer since it will take the longest to cook.
