Final answer:
Cook a raw chicken casserole at 350° Fahrenheit for 45 minutes to ensure it is thoroughly cooked and safe to eat, using a thermometer to check the food's internal temperature.
Step-by-step explanation:
To cook a raw chicken casserole, the temperature you should use is 350° Fahrenheit. This temperature is sufficient to both cook the casserole throughout and ensure that it reaches a high enough internal temperature to kill any bacteria that may be present. As per the given recipes, the casserole should be covered with aluminum foil and baked for 45 minutes when using small birds like dove or quail, or for 30-45 minutes when preparing a dish that includes duck. Always remember to check that the food has reached the safe minimum internal temperature by using a thermometer.
