Directions

1. In a large pot over low heat, melt butter then add flour and stir to combine. Cook for a minute stirring frequently then add milk slowly and whisk to combine until smooth. Cook over low heat until milk thickens, about 3-5 minutes. Add mustard, salt, white pepper, cayenne pepper, cheddar, provolone and parmesan and stir until it melts. Add the pasta to the sauce and cook for an additional minute. Remove from heat and allow to sit for 5 minutes so the sauce can thicken. Serve!
