Ingredients and Equipment

• 3 cups leftover Mac and Cheese, cooled to room temperature
• 1 egg, lightly beaten
• ½ cup shredded cheddar cheese (see notes below for other tasty cheese options)
• 2 ½ tablespoons panko bread crumbs
• ½ tablespoon melted butter
• 1 pinch paprika

Step-by-Step Instructions

1. Melt butter in a medium saucepan.
2. Whisk in flour and stir constantly for 40–50 seconds to cook the raw flour.
3. Slowly pour in milk while whisking, then add water, salt, and pepper.
4. Cook until the sauce starts to simmer and thickens, stirring frequently.
5. Add macaroni noodles, lower heat to medium–low, and stir occasionally until noodles are just shy of al dente (about 8–10 minutes).
6. Remove from heat and stir in cheese and a pinch of paprika until smooth and the cheese is melted.
7. Let the macaroni and cheese cool to room temperature and measure out 3 cups.
8. Preheat oven to 425°F and generously spray a 6-cup muffin pan with cooking spray.
9. In a medium bowl, combine 3 cups cooled mac and cheese, 1 beaten egg, and ½ cup shredded cheddar; mix thoroughly.
10. In a small bowl, stir together 2½ tablespoons panko, ½ tablespoon melted butter, and a pinch of paprika to make the topping.
11. Spoon the mac and cheese mixture into the greased muffin pan, pressing down gently to form cups.
12. Sprinkle the panko topping evenly over each cup.
13. Bake for 20–25 minutes until the tops are deep golden brown and crispy.

14. Let the cups cool 5–10 minutes, run a butter knife around each edge to loosen, and lift them out gently from the pan.

Pro Tips for Best Results

• Make sure you grease the muffin pan really well—these cheesy bites tend to stick, and a good spray helps them come out cleanly.
• To pop the muffins out easily, run a knife around the edges before gently lifting them up. If you’re using paper liners, cool the muffins fully before peeling the liners off slowly to keep them intact.
• Using macaroni and cheese at room temperature works best. Cold pasta is firm and harder to mix, causing the muffins to fall apart.

Flavor Variations and Add-Ins

While most leftover mac and cheese works, you’ll get the best results with a thicker, creamier batch. This helps the bites hold their shape and gives you a rich, cheesy taste in every bite.

• Homemade macaroni: My creamy homemade mac and cheese has just the right sauce-to-pasta balance and a deep flavor that keeps the muffin cups soft inside with that perfect cheesy bite.
• Boxed (like Kraft): Got boxed mac n cheese on hand? It’s a great shortcut! Just make sure it’s thick and creamy enough to scoop and shape well—avoid runny versions.
• Baked Casserole: This style tends to be dense, so it’s not ideal. However, if that’s what you have, stir in a splash of milk or extra shredded cheese to loosen it before baking.

Tip: Always let your macaroni cool to room temperature before shaping into cups—this step is key to keeping them together.

Stick with the same cheese you used to make your macaroni so the flavors stay cohesive. I like sharp cheddar for its bold, classic taste in my homemade batch—if you love broccoli-cheddar vibes, take inspiration from this broccoli cheese casserole recipe and fold in finely chopped, steamed broccoli. If using boxed mac, try boosting it by mixing in a few shredded cheeses: gruyère adds a lovely nutty note, gouda or Monterey Jack brings melty creaminess, and Swiss amps up the flavor complexity. Mixing cheeses is a small step that makes a big flavor difference for these mac and cheese cups.

Storing and Reheating Tips

Storing your mac and cheese cups: Pop any leftovers in an airtight container and store in the fridge for 3 to 5 days. For longer storage, freeze them in a sealed zip-top bag for up to a month.

Reheating tips: Warm frozen cups in a 350°F oven for 15-20 minutes or pop them in an air fryer for 8-10 minutes at the same temperature to bring back that crispy crust. If you’re in a hurry, microwave for 1-2 minutes, though keep in mind they won’t be as crispy with the microwave method.

Troubleshooting and FAQ

I recommend skipping paper liners and greasing the muffin pan generously instead. This method gives those mac and cheese cups a beautifully crisp, golden crust along the edges you just can’t get with liners. If you prefer liners for easier clean-up, make sure to let the cups cool completely before peeling them off carefully—that helps avoid sticking and breaking apart.

Bake these at 425°F for 20 to 25 minutes until the tops turn a deep golden, crunchy crust.
