Preheat the oven to 450 degrees Fahrenheit.

Step 5

Place the turkey in the oven and roast for 20 minutes. After 20 minutes, reduce the heat to 350 degrees Fahrenheit. Continue roasting for an additional 1 hour and 15 minutes, or until a quick read thermometer in the thigh registers at 170 degrees Fahrenheit.
