So you made too much mac and cheese. Now what do you do?

Turn them into these cups!

These poppable bites let you eat your mac and cheese on the run. 

With the help of an egg, you can bind them into muffins. Top each one with breadcrumbs, butter, and paprika for a little extra oomph. 

Whatever you won’t eat in a few days, freeze for later. 

2. Crispy Mac and Cheese Balls

These mac and cheese balls are little morsels of heaven.

Breadcrumbs give them a crispy coating, while the inside is oozing with gooey mac and cheese. 

To keep them from falling apart, chill the mac and cheese for a few hours.

An ice cream scooper also helps achieve the perfect serving. 

Appetizers or snacks, they’re a guilty pleasure everyone will devour. That’s a good thing, too, because these yield a large serving. 

3. Leftover Mac and Cheese Soup

Mac and cheese soup? Sure, I’ll give it a try!

If you like very rich comfort food, you should try it too. 

You plop those leftovers into a thick creamy base of cheese, milk, and broth. 

Use non-dairy and meat-free ingredients to keep it vegan-friendly. Or ramp up the decadence with cow’s milk, butter, and chicken stock.

4. Mini Leftover Mac and Cheese Quesadillas

These quesadillas are epic! 

Stuffed between two mini flour tortillas is a mound of leftover mac and cheese. As for add-ins, use any fillings you like. 

Bacon, avocado, caramelized onions, or hot sauce, there are plenty of variations. 

The smaller size is great for a snack or a party appetizer.

For those getting hangry, swap out the tortillas for burrito sized. 

5. Mac and Cheese Grilled Cheese

Next to quesadillas, grilled cheese is my other favorite way to use leftover mac and cheese.

The inside is oozing with mac and cheese goodness. Butter also gives the golden brown sourdough the best crunch.

To any hot sauce lovers, I say douse away!

Turn Meatless Monday leftovers into a Taco Tuesday treat with leftover mac and cheese.

This clever idea is one that even picky eaters can’t refuse.

To top off the tacos, sprinkle each one with crushed Ritz crackers. 

For a boost of protein, chicken, ham, or beef work well as fillings.

11. Macaroni and Cheese Stuffed Peppers

Mac and cheese just found a new home in these peppers.

12. Macaroni and Cheese Pizza

Next pizza night, I know what I’m making!

This is such a fun pizza topping idea. It’s also one that the family will agree on. 

It features mac and cheese, bacon, and extra cheese. With a hefty topping like that, you need a thick crust to match. 

Be sure to not roll it out too thin. You need it thick enough to support all the yumminess on top.

13. Macaroni and Cheese Egg Rolls

On the outside, these look like your typical egg rolls. But on the inside, they’re packed with mac and cheese and bacon.

Every egg roll also needs a dipping sauce to match. So use your favorite barbecue sauce.

To achieve the perfect texture, double check the temperature of your oil. 

Too hot and these will burn. Too low and they won’t cook right. 

14. Mac and Cheese Smashed Burgers

Doesn’t this remind you of one of those things you’d see on a food show?

They’re so flavorful, you won’t need a sauce on the side. 

17. Pepperoni Mac and Cheese Skillet

Mac and cheese lines the bottom of the skillet, acting as a crust. On top, pepperoni and mozzarella turn it into pizza. 

Spoil the family and make this for dinner. They’ll think you’re the best parent ever!
