The time required to reheat a chicken casserole in the oven can vary depending on factors such as the casserole’s size, thickness, and the temperature at which you’re reheating it. As a general guideline, you can follow these steps:

  1. Preheat the Oven: Set your oven to a moderate temperature, typically between 325°F to 350°F (163°C to 177°C).
  2. Choose the Right Dish: Select an oven-safe dish that can accommodate your chicken casserole without overcrowding. A glass or ceramic baking dish is preferable.
  3. Add Moisture: To prevent the casserole from drying out during reheating, add a small amount of moisture. You can drizzle chicken broth, gravy, or a splash of water over the casserole.
  4. Reheating Time: The time it takes to reheat a chicken casserole depends on its size and thickness. Here’s a general guideline:
  5. Check the Temperature: Use a food thermometer to check the internal temperature of the chicken casserole. Ensure it reaches a minimum of 165°F (74°C) to guarantee its safety for consumption.
  6. Final Touches: Optionally, uncover the casserole to allow the top to crisp up or add a sprinkle of fresh herbs for added flavor. Let the casserole rest for a few minutes before serving.

Keep in mind that these are general guidelines, and the actual reheating time may vary based on your specific oven, the casserole’s thickness, and other factors. It’s always a good practice to monitor the reheating process and use a food thermometer to ensure that the entire casserole reaches the recommended safe temperature.

You want to ensure that the method you use when heating chicken casserole does not leave it dry. This article will show you how to achieve this through the various reheating methods. Let’s look at them!

1. Reheat Chicken Casserole in the Oven

The oven remains the ideal way to reheat your chicken casserole. Since it may have some stew in it, it may not easily burn when you reheat it from the oven. While using the oven, the chicken casserole may take about 20 minutes to get ready if it is thick.

When it is in small pieces, 15 or fewer minutes should be enough to make it hot. Also, eventually, your chicken casserole will not be dry. Below are the steps you should follow when reheating it using the oven:

  1. Remove the chicken casserole from the fridge and place it at the kitchen counter. Doing this allows it to get to room temperature before reheating it. If it was in the freezer, get it out 20 minutes earlier to allow enough time for defrosting.
  2. As the chicken casserole defrosts, preheat the oven at 350. It will ensure that the chicken casserole starts to get the heat immediately after putting it in the oven.
  3. Prepare the chicken casserole for baking. If the pieces are large, cut them up into smaller pieces. You want to ensure that the inside heats up evenly.
  4. Place the casserole in the baking dish or tray. Cover it up with aluminium foil so that the juices in the chicken casserole do not escape. The aluminium foil will also ensure that its edges do not burn.
  5. Allow it to bake for about 20 minutes, but this is dependent on the size of the casserole. If they are thick, this time will be enough. Smaller and thinner pieces will take about 15 minutes to be ready.
  6. Once this time elapses, you can switch off the oven and remove the chicken casserole from it.
  7. Allow it to sit for about two or three minutes to cool. Then serve.

2. Reheat Chicken Casserole in the Microwave

The microwave will be an excellent reheating option if you are reheating just a small portion of the chicken casserole. It is much easier to use and will ensure that the pieces do not get dry. Also, the microwave will need only a few minutes for the chicken casserole to be ready. Here is how you do it:

  1. Start by getting the chicken casserole out of the fridge to defrost for a few minutes.
  2. When using the microwave, the chicken casserole will get hot outside, quickly leaving the inside cold. So, cutting it into small pieces helps prevent this. Cut it up into smaller pieces for easier and even reheating.
  3. Place the pieces you just cut in a microwave-safe dish. The microwave may destroy other kinds of dishes.
  4. Be sure to spread the pieces out well not to touch each other. Such will ensure that they get the heat on all sides.
  5. Cover the dish with a wrap that is safe to use in the microwave. However, ensure you leave a small gap on the wrap so that the steam can escape.
  6. Allow the chicken casserole to heat in the microwave for about 2 or 3 minutes.
  7. It is okay first to allow them to heat up for one minute. After this time, you can remove the chicken casserole and turn the pieces to the other sides. You do this to ensure all the sides get the heat.
  8. Put the pieces back and allow them to reheat for another one minute.
  9. After this, you can check whether the chicken casserole is at the heat you desire. If it is not yet there, allow it to cook for 30 seconds. You can finally remove it from the microwave and serve.
