2 tablespoons unsalted butter
2 clove garlic, minced
2 teaspoons grated lemon zest
4 teaspoons all-purpose flour
2 cups low-fat (2%) milk
1 teaspoon salt
4 tablespoons low-fat cream cheese
1.5 cups grated parmesan cheese
0.25 cups chopped parsley
Melt the butter in a skillet over medium heat. Add the garlic and lemon zest and cook until the garlic is slightly soft, about 1 minute. Add in the flour and cook, stirring with a wooden spoon about 1 minute. Whisk in the milk and salt and cook, whisking constantly, until just thickened, about 3 minutes.
Add the cream cheese and parmesan cheese; whisk until melted, about 1 minute. Stir in the chopped parsley.
Serve with pasta (1 pound) of your choice.
