Final answer:
When reheating a cooled chicken casserole for hot holding, it must reach a safe temperature of 165°F (74°C). Stirring and using a food thermometer are key steps in this process. Exact times will vary based on microwave wattage and dish size.
Step-by-step explanation:
When reheating a chicken casserole for hot holding after it has been cooled to 41 degrees, it is crucial to ensure the food reaches a safe temperature to kill any potential bacteria. According to food safety guidelines, food should be reheated to at least 165 degrees Fahrenheit, which is 74 degrees Celsius. In the context of using a microwave for reheating, make sure you stir the casserole occasionally to distribute heat evenly, as microwaves can heat food unevenly.
Use a food thermometer to check the internal temperature of the casserole to guarantee that it has indeed reached 165°F (74°C) throughout. To avoid overcooking while ensuring safe consumption, cover the dish and rotate it during the process if the microwave does not have a rotating plate. Since microwaves vary in power, the exact time to reheat the casserole will depend on the microwave's wattage and the size of the dish. As a general guideline, start with the microwave's reheat setting or high power, and check the temperature periodically.
