In a saucepan over low heat, combine the milk, cream cheese, butter, parmesan cheese, and chipotle in adobo sauce.
Stir to combine, then allow the mix to simmer, stirring continuously, for 5 minutes or until the cheese is melted and all ingredients are fully combined.
Use immediately over pasta.
Notes
Want it as a dip? Simmer for a little longer to thicken the sauce.
