Step 1

Cook pasta according to package directions. I recommend cooking the pasta a minute less than the directions.  Drain and set aside for a few minutes.

Step 2

To prepare roux, melt butter into a medium saucepan over medium heat. Once melted whisk in flour, salt and pepper. Stir and cook for 3-4 minutes until color of roux gets slightly darker. Slowly whisk in milk, stirring continuously until thickened, about 2 minutes. Reduce heat to a simmer and stir in cheese until melted.

Step 3

Transfer cooked pasta to large dutch oven or pot over low heat. Pour cheese sauce over top, stirring to combine. This is a thick and creamy sauce. To thin the sauce, add a few tablespoons of milk at a time until at desired consistency.
