Step 2: Place Turkey in Covered Roaster, Breast Side Up.
You can put an onion, an apple, garlic, fresh herbs in the cavity or add stuffing instead and adjust cooking time upwards by thirty minutes. Disposable aluminum pans are not recommended for roasting a whole turkey. The weight of the turkey may cause the pan to buckle when it is removed from the oven, creating a dangerous situation. The timetables are guidelines only for unstuffed birds roasted at 325 degrees. Remember, the only true gauge for determining proper doneness is with a meat thermometer. The breast must reach an internal temperature of 170 degrees and the thigh must reach an internal temperature of 180 degrees Farenheit.
