Reheat Mac And Cheese

I was born in 1982 and a 90’s kid. This meant that I was raised on the canned foods that were reheated in the microwave.

There were cans of Campbells meatballs, Heinz spaghetti Bolognese, Heinz spaghetti loops and let’s not forget about Heinz macaroni cheese.

And let’s be honest, they didn’t taste very good and I doubt the cheese was quality that was going into the cans.

But as a kid, you didn’t know any better, and as a parent you never realised how unhealthy there were.

Their best selling point was how quick you could reheat your cans of macaroni cheese in the microwave and that 2-3 minutes later you had macaroni cheese in a bowl and your kid fed.

I was thinking about that, as I am stood over the air fryer reheating mac and cheese. How it takes just as long to reheat mac and cheese in the air fryer as it does the microwave. Or how you can create so many different things from leftover mac and cheese, that you will never need a can again.

Leftover Mac And Cheese

It was from our slow cooker mac and cheese recipe. Which is a great way to make mac and cheese in bulk and ideal for serving over a few days.

How Long Is Leftover Mac And Cheese Good For?

Leftover mac and cheese is good for 2-3 days. Even though it is meatless, mac and cheese carries a lot of dairy which does not have a long shelf life for reheating.

What I recommend is that you plan ahead. Imagine you are making macaroni cheese for dinner on Monday, that you plan into your dinner menu that you are going to serve mac and cheese on the Tuesday or Wednesday.

Best Way To Reheat Mac And Cheese?

How To Fix Dry Mac And Cheese?

The secret tip to help your dried mac and cheese creamy again, is to add in loads of milk.

I know it sounds silly, but the reason you have dry mac and cheese is because your cheese has dried out and the macaroni and cheese has been starved of liquid.

The easy way to fix dry mac and cheese is simply to load it up with 240ml (1 cup) of skimmed milk and reheat it on the stovetop.

Then gradually add a bit more milk, then a bit more milk until it is creamy enough.

Or if you feel after this its no longer dry, but not creamy, then add in about two tablespoons of cream cheese.

You can also use this same method to rescue mac and cheese, not just for reheating.

Stir it and you will have perfectly cooked creamy mac and cheese.

Can You Freeze Cooked Macaroni And Cheese?

However, if you have other plans and know that you wont be able to consume your mac and cheese in the reheat window, I recommend freezing it instead.

The freezer is fantastic for storing your leftover mac and cheese and we recommend you wait until its 100% cool before reheating to avoid condensation.

To freeze your leftover macaroni cheese, I recommend you load it into either zip loc bags, foil containers of glass bottom storage containers. Then label it up to help you remember what it is, when dumped in the freezer and save it for later.

Your macaroni cheese can then be consumed within 3 months.

Notes

Variations. Remember, you can follow any of these leftover mac and cheese recipes I have suggested. But note, slow cooker Bolognese mac and cheese is aimed at lots of leftovers, whilst the others are for a small leftover portion.

Milk. I recommend skimmed milk for making your dry leftover pasta moist again, but if you want creamy go with coconut milk or cream cheese such as Philadelphia.
