1 pound uncooked penne
1/4 cup all-purpose flour (about 1 ounce)
3 cups fat-free milk
2 cups (8 ounces) shredded fontina cheese
1/4 cup (2 ounces) mascarpone cheese
3/4 teaspoon salt
1/4 teaspoon freshly ground black pepper
1/2 teaspoon freshly grated nutmeg
1 cup Italian seasoned breadcrumbs
1 tablespoon butter
1 small garlic clove, minced
1 1/2 tablespoons chopped fresh parsley
Cook pasta according to package directions, omitting salt and fat. Drain; keep warm.
Preheat oven to 350°.
Lightly spoon flour into a dry measuring cup; level with a knife. Combine flour and milk in a large saucepan over medium heat, stirring with a whisk. Cook 10 minutes or until thick, stirring constantly with a whisk. (It will still be runny after ten minutes. Don't worry, it will thicken in the oven.) Remove from heat; add cheeses, stirring with a whisk until smooth. Stir in salt, black pepper and nutmeg. Add cooked pasta, stirring to coat. Spoon pasta mixture into a 13 x 9-inch baking dish coated with cooking spray.
Melt butter in a small skillet over medium heat. Add garlic; cook 30 seconds. Remove from heat. Stir in breadcrumbs until well combined. Sprinkle breadcrumb mixture evenly over pasta mixture. Bake at 350° for 25 minutes or until bubbly. Sprinkle with parsley.
