Stir until warmed through (do not boil), then add the Mozzarella, Sharp Cheddar, Colby Jack, and Gruyere (all of the cheese except the 4 oz of cheddar cheese). Add mustard, garlic powder, onion powder, seasoned salt, paprika, and cayenne pepper, and cream cheese. Stir until combined, then taste for salt and pepper.

Step 5

Whisk together sour cream and cornstarch in a small bowl until all of the cornstarch is incorporated into the sour cream. Add to the pot and stir until combined.

Remove from the heat and add in the seasoned noodles. Stir until all of the noodles are coated in the cheese sauce. Add eggs and mix until combined.

Step 7

Add half of the macaroni and cheese into the pan, then add the mozzarella cheese slices in an even layer. Add the remainder of the macaroni and cheese on top. Sprinkle the remaining 4 oz of cheddar cheese macaroni and cheese on top.
