Begin by taking a handful of your leftover mac and cheese and squeezing into about a 2 tablespoon ball. Do this until you run out of mac and cheese. Set aside.
Beat the eggs into a bowl. Whisk in your milk. Set aside.
In a separate bowl or on a plate, mix together your bread crumbs and seasonings.
Grad a ball of mac and cheese, place in the egg & milk mixture until fully coated. Then roll around in the breadcrumb mixture until fully coated. Place on a sheet of parchment paper. Repeat this for each ball.
Once all of your balls are coated in both your egg mixture and the breadcrumbs, place in the freezer for 30 minutes.
Remove from the freezer and place in the air fryer. Make sure the balls do not touch.
Cook each round of mac and cheese bites on 360 degrees for 8-10 minutes or until golden brown.
When the timer is up, remove from the air fryer and serve immediately.
