Fill a large pot with salted boiling water. Add the macaroni pasta and boil for 5 to 7 minutes or until just al dente. Drain the pasta and set aside.

In the same pot, add the butter and melt over medium heat. Add the flour and stir with a whisk for 2 to 3 minutes. Slowly add the milk and continue to stir with the whisk until smooth and the mixture has slightly thickened to coat the back of a spoon. Add the cheeses and stir until melted. Add the mustard, smoked paprika, cayenne pepper, and salt & pepper to taste. Stir in the cooked pasta.

Serve and enjoy!
