Mostaccioli, known in Italy as “Penne Lisce,” are a specialty of the Campania Region in Southern Italy, which includes the cities of Naples, Capri, and Sorrento. Penne are tube-shaped with angled ends cut to resemble a quill or pen point. Unlike Penne, which are ridged, Mostaccioli are smooth in texture. Try Mostaccioli with fresh, light sauces like olive oil or a simple fresh tomato sauce. Mostaccioli is also great for baked casserole dishes, known as pasta al forno,” which is delicious with cheese-based sauces.
