Creamy Alfredo Tortellini

1 (18 oz) package refrigerated three cheese tortellini
4 T unsalted butter
6 cloves garlic, minced
1/2 t crushed red pepper flakes
4 T flour
2 c milk
1 c half and half
4 oz cream cheese, cubed (Or you can substitute with some sour cream)
1/2 c Parmesan cheese
salt and pepper, to taste

In a large pot of boiling salted water, cook tortellini according to package instructions; drain well.
Melt butter in a saucepan over medium heat. Add garlic and red pepper flakes, and cook, stirring frequently, until fragrant, about 1 minute. Whisk in flour until lightly browned, about 1 minute.
Gradually whisk in milk and half and half, and cook, whisking constantly, until slightly thickened, about 2-3 minutes. Stir in cheeses until melted, about 1-2 minutes. If the mixture is too thick, add more milk as needed; season with salt and pepper, to taste. Stir in tortellini and gently toss to combine. Garnish with Parsley.
