Cook the pasta accordion to the directions. It is best to cook the noodles al dente.
Once the macaroni is cooked, drain and transfer to a bowl. Set it aside.
Preheat your oven to 350 degrees.
To make the sauce, add milk, unsalted butter, and heavy cream to a pan.
Make sure the butter has melted first, and then add the pasta on top.
Add the ground nutmeg, Velveeta cheese, mustard powder, Gruyere cheese, salt, and pepper.
Transfer the mixture to the baking dish. Sprinkle some Cheddar cheese over, if you’d like.
Bake for half an hour.
Allow your mac and cheese to cool for a few minutes before serving.
