Boil water to cook the pasta, al dente. While that’s boiling, brown the bacon. Place in a paper towel lined plate to set aside. In a medium pot, melt the butter. Add the milk and the cheeses.
Whisk gently until everything is incorporated. Season with salt, black pepper, garlic powder, and Italian seasoning.
Preheat the oven to 355°. Drain the water off of the pasta. Pour the cheese sauce into the pasta then add the bacon. Stir everything together.
