Leftover Mac and Cheese is a regular occurrence in our house with young kids. We have started getting super creative on how to use our leftovers so it’s not the same old thing every night.

Plus, macaroni and cheese can lose its cheesy flavor the next night and you need something with more flavors to bring it back to life!

I’ve put together 12 leftover mac and cheese recipes to make dinner that much more enjoyable – and easy to make! Just make extras and enjoy these recipes the day after.

How to Make Leftover Mac and Cheese Creamy Again

Macaroni and cheese can lose a lot of its flavor the next day, so it’s important to turn it back creamy and flavorful when eating it as leftovers.

The best way to revive mac and cheese is to do 2 things when reheating it:

  1. Add 1 tablespoon of butter (more if reheating a bunch)
  2. Add 1 tablespoon of milk per plate of mac and cheese

You can also add additional shredded cheddar cheese to add more of a cheesy flavor the next day.

Add these before reheating for the best results.
