We make macaroni and cheese for the cheese sauce, and this recipe how to shows you how to make the silkiest, creamiest and most cheesy smooth sauce for mac and cheese every time. 
Tips for a Smooth Cheese Sauce
Shred cheese off the block for a smooth cheese, never use pre shredded because it won't melt as smoothly since there are anti caking ingredients in it.
Use one part semi sharp to sharp cheddar, with one part mild cheddar cheese.
Couple that combination with just a bit of either American or cream cheese which will make it ultra silky and creamy.
The American cheese or cream cheese act as an anchor to blend the rest of the cheese into a smooth state. 
In addition to melting the cheeses correctly, you can reserve a half to one cup of the pasta water after you've boiled your pasta.
You might not need the pasta water, but if you notice the cheese sauce isn't clinging to the noodles, a splash of this will make the cheese sauce loosen up and stick to the pasta. 
Follow the directions in the recipe card below for perfect, stove top macaroni and cheese and you will never buy boxed brand again!
