What cheeses can I substitute in this Macaroni and Cheese recipe?

white Sharp cheddar and shredded mozzarella or Colby, american cheese

You can really use any cheese you want if you make a sauce resembling a mornay sauce which is what the recipe in your question calls for.

Just follow that same recipe and use the correct amounts of whatever cheese you choose to use

The reason you want to make the mornay(ish) sauce is to avoid a mealy texture. The cheese needs to bind with the milk/flower/butter mixture so that it's nice and creamy.

Good luck

you can use most hard cheeses in mac cheese,try gouda or emmental mixed with cheddar heres a nice recipe,enjoy!
