How to Reheat Chicken Casserole in the Oven

A Guide to Deliciously Reheating Your Chicken Casserole

We all know the feeling of having leftover chicken casserole sitting in our refrigerator, waiting to be enjoyed again. But reheating it properly can be a bit tricky. You want to make sure it’s heated evenly and maintains its original flavor and texture. In this guide, we’ll walk you through step-by-step instructions on how to reheat your chicken casserole in the oven, ensuring a mouthwatering meal every time.

Gather Your Equipment

Before diving into reheating your chicken casserole, gather the necessary equipment:

1. Oven-safe dish: Ensure you have an appropriate-sized dish that can withstand high temperatures.
2. Aluminum foil: This will help retain moisture during reheating.
3. Oven mitts: Protect your hands from hot surfaces while handling the dish.

Preheat Your Oven

The first step is preheating your oven to 350°F (175°C). Allow sufficient time for it to reach this temperature so that your casserole is cooked evenly throughout.

Prepare Your Casserole Dish

Take out your chicken casserole from the refrigerator and transfer it into an oven-safe dish if it isn’t already in one. Make sure the dish is deep enough for proper heating without overflowing or drying out the edges of the casserole.


For added moisture retention, lightly brush or spray some olive oil over the surface of your chicken casserole before placing it in the oven.

Cover with Foil

Once transferred into an appropriate dish, cover your chicken casserole tightly with aluminum foil. This will prevent excess moisture loss during reheating, keeping your casserole juicy and flavorful.

Reheating Time

Place the covered dish with your chicken casserole in the preheated oven. The reheating time may vary depending on various factors such as portion size, initial temperature, and oven efficiency. As a general guideline, allow your chicken casserole to reheat for approximately 20-30 minutes.


Every oven is unique! Keep an eye on your chicken casserole while it reheats to ensure it doesn’t over or undercook. Adjust the reheating time accordingly based on visual cues like bubbling edges or steam escaping when you briefly lift the foil.

Check for Internal Temperature

To guarantee that your chicken casserole is safely heated through, use a food thermometer to check its internal temperature. Insert the thermometer into the center of the dish without touching any bones or hitting bottom; it should register at least 165°F (74°C).


If you don’t own a food thermometer but want to visually assess if your casserole has reached a safe internal temperature, look for uniformly hot bubbling throughout.

Serve and Enjoy!

Once you’re satisfied that your chicken casserole is thoroughly reheated and safe to eat, carefully remove it from the oven using oven mitts. Let it cool slightly before serving to avoid burning yourself. Serve alongside some fresh greens or crusty bread for a complete meal!

With these simple steps, you can effortlessly reheat leftover chicken casserole in an oven while preserving its deliciousness. Say goodbye to dried-out microwave meals and relish every bite of this comforting dish all over again!
