Things You'll Need
Turkey is a popular main course for many holidays, such as Thanksgiving and Christmas. One of the most popular ways to cook a turkey is roasting it. Lower roasting temperatures, including 300 degrees, require greater cooking time. Just be advised that the USDA does not recommend cooking a turkey at lower than 325 degrees.
Thaw the turkey if you purchased it frozen. According to the USDA, there are three safe ways to thaw a turkey: leave it in the refrigerator for roughly 24 hours for every 4 to 5 pounds; place it in cold water, allowing about 30 minutes per pound; and defrost it in the microwave oven, according to your microwave's specific instructions.
Clean the turkey. Once the turkey is thawed, you must next clean the turkey by removing the giblets from the inside. Gently rinse the bird with cool water externally and internally.
Season and stuff the turkey. At this stage, you should add any seasonings you want to include in your cooking. Additionally, add any stuffing you want to insert into the turkey. Alternatively, you can cook your stuffing separately in a casserole dish.
Preheat the oven to 300 degrees.
Cook the turkey. Place the turkey in a cooking pan large enough to catch any juices. Place the turkey and pan in the oven. Medium to large turkeys should be cooked for roughly an hour for every 4 to 5 pounds, slightly longer for a stuffed bird.
Test the temperature. Using a meat thermometer, ensure that the internal temperature of the turkey is at least 165 degrees.
When cooking any poultry, including turkey, make sure the meat is fully cooked. Undercooked poultry might contain harmful bacteria such as salmonella.
