Ingredients
Method
- Preheat the oven to 350°F. Pour the water into a 3-quart pot and bring to a boil over high heat. Meanwhile, cook the bacon or prosciutto, drain and crumble and set aside.
- In a small sauce pan, melt 2 1/2 tablespoons of the butter over low heat. Add the bread crumbs and Parmigiano-Reggiano cheese, toss well, and set aside.
- Put the remaining 3 tablespoons butter in a 2-quart, heavy-bottomed saucepan and melt it over low heat. Add the flour and cook for 5 minutes, whisking constantly, but not letting the flour burn. Pour in the milk and cook for 5 minutes, whisking or stirring with a wooden spoon. Add 4 1/2 teaspoons salt, 4 grinds of pepper, the Gruyère, Fontina and mascarpone, dashes of nutmeg and cayenne, and continue to whisk until the cheese is melted and incorporated. Remove the pot from the heat.
- Add 1 tablespoon of salt and the pasta to the boiling water and cook until al dente, approximately 8 minutes. Drain the macaroni in a colander and add it to the pot with the cheese sauce. Add crumbled bacon or pancetta and mix well with a wooden spoon.
- Pour the macaroni mixture into an 8-inch by 8-inch baking dish. Sprinkle the breadcrumb mixture evenly over the top of the macaroni and cheese. Bake until golden brown and bubbly, approximately 30-35 minutes. Serve hot and garnish with fresh parsley.
