Once the moisture has been absorbed out of the dish, it will no longer be a satisfyingly delicious meal

In this article we shall take a look at two ways to reheat leftover casserole, and how to store the leftovers properly.

How Should You Reheat Leftover Casserole To Make Sure It Does Not Go Dry?

Here are two ways to reheat leftover casserole without it going dry:

Using The Microwave To Reheat A Casserole

Using the microwave is best if you only have a portion to reheat. However, this does not mean you cannot use it otherwise. Here are a few simple steps:

Step 1

Once the casserole has been defrosted, you will need to either place the portion that is left  into a microwavable container, or slice a few portions and place them into the microwavable container.

Step 2

Add the lid or plastic wrap to the top of the microwavable container. Make sure to either stab a few holes into the top of the plastic wrap, or to place the lid on with a gap.

There needs to be an opening so the steam can rise and escape from the food. 

Step 3

Let the microwave do its job for around a minute. Once the time has passed, remove the casserole slice(s) and turn them so the microwave can heat all of the sides up.

Step 4

Keep microwaving the casserole for 30 seconds at a time until it is piping hot throughout the whole slice(s). However, make sure not to overdo it!

Do keep in mind that the more casserole slices that there are, the longer it will take, hence it is a much quicker job to do with one slice (portion) of casserole.

Using The Oven To Reheat A Casserole

When it comes to using the oven, it does a great job at reheating a few leftover slices of casserole. Also, the oven method is very straightforward and easy to do, however it takes much longer than in the microwave.

Step 1

Take the casserole out of the refrigerator and allow it to sit at room temperature for around 20 minutes. This also allows the oven to heat up to 350 degrees Fahrenheit. 

Step 2

Add the leftover casserole onto a baking tray and cover with some aluminum foil. This will ensure that the casserole stays juicy and that it will not burn.

Step 3

Depending on the thickness of the casserole, cook the casserole for around 20 minutes. Change this accordingly. For example, if the slices are thinner, then only do it for 15 minutes. 

Step 4

Once it is piping hot throughout, remove from the oven, let it cool for a couple of minutes and then serve. 

How Should You Store Leftover Casserole?

How Should You Store Leftover Casserole?

Once you have some casserole leftovers, you should always put them in the fridge. Leaving casserole at room temperature, no matter the ingredients, will limit the amount of time the food will last before going bad.

A casserole often has different types of sauces, veggies and meat, and each one is highly susceptible to the dangers of bacteria when put at room temperature. 

So, to avoid food poisoning, always put the casserole in the fridge as soon as possible. This will make the casserole last a few days extra rather than a couple of hours. 

While reheating a casserole will never be as fresh as it was the first time around, it will still be just as tasty. To store, transfer the casserole into an airtight container and put it into the refrigerator. 

How Long Will A Casserole Last In The Fridge Before Going Bad?

While putting the casserole into a cooler temperature will help it to last longer, at the end of the day, it is food. That means that every day it is on a countdown to going bad.

More often than not, the casserole will last for up to around 3 days. With each day that passes, the least fresh it will be. By the fourth day, it may still be okay to eat, but you will want to check before consuming it.

If the casserole has mold, discoloration or has an odd smell or taste, then discard it. You will want to avoid it once anything changes, as it means bacteria is present.

However, do always keep in mind the ingredients when wondering how long the casserole will last. Expect cream and cheese sauces to last only a matter of a day or two compared to meat and so on. 

If you want a cheesy casserole to last a lot longer, always consider putting it in the freezer, even if you are planning to eat it that very same week.  

Can You Freeze Leftover Casserole?

If you already know that you will not be consuming the casserole for a number of days, then the best thing to do will be to freeze it. Not only will it last much longer than just putting it in the fridge, but it may hold onto some of the freshness too. 

Often people purposely make a casserole in batches to freeze, this way they can whip up a quick meal for the kids later on in the week – or month!

If you are planning to dish it up as separate meals, a good trick is to freeze a portion size at a time. This makes defrosting it much easier. 

To do so, place it in the fridge overnight to ensure it becomes fully defrosted and ready to be reheated. If you are planning to use the oven method, always allow the casserole to sit at room temperature for up to 20 minutes. 

A casserole may last for 3 to 6 months in the freezer, with the possibility of it lasting even longer. However, the longer you leave it frozen, the higher the chance it will not be as tasty or as fresh as it once was. 

Final Thoughts

It is common to have leftover casserole due to the fact it is made as a big batch. Instead of throwing it out, or putting it at the back of the fridge to be forgotten about, there are two ways to reheat it without it going dry.

If you make sure to reheat the casserole in a particular way by using a microwave (for a quick one portion) or the oven (for a longer cooking time for a big batch), you will be able to reheat the casserole without it going dry.

Hopefully you will have found the perfect technique for you within this article. You can be sure that you will no longer have to put up with eating a dry and crispy reheated casserole that doesn’t taste very fresh or flavorsome.
