Bring a large pot of water to a boil.
Season the water well with salt then add the pasta.
Broil for 9-10 minutes, strain the pasta once it is cooked.
Place pasta back in the pot with the cheese and ½ cup of milk.
Stir over medium heat until all of the cheese is melted, add more milk as needed.
Add salt and pepper to taste.
Pour the pasta onto a parchment-lined baking sheet.
Spread it evenly to the thickness you want for your buns.
Cover the Mac & Cheese with plastic wrap then freeze for 2-4 hours.
Once the Mac & Cheese is frozen remove it from the parchment and cut it into the shape of buns.
Set up a breading station with flour, egg, and breadcrumbs.
Make sure the buns are well coated in breadcrumbs.
Heat oil in a pan over medium-high heat.
Fry for 2-3 minutes per side until golden brown.
Set on a paper towel-lined plate and repeat with the other buns.
Brown the Goetta patties in a pan with a small amount of oil for more even browning.
Assemble your burger with all of your favorite toppings and enjoy!
