In how many time should a turkey be in oven?

The cooking time for a turkey varies depending on the size of the bird and the oven temperature. A general rule of thumb is to cook the turkey at 325 degrees Fahrenheit for 20 minutes per pound. So, for example, a 12-pound turkey would need to cook for about 4 hours. However, it is always best to use a meat thermometer to ensure that the turkey is cooked to the proper internal temperature of 165 degrees Fahrenheit.
