The breaded chicken pieces stay crispy and crunchy when kept separate from the pasta and sauce. But this dish can also be made by placing the pasta and sauce in a large baking dish, then placing the crispy Chicken Parmesan over the pasta before baking. However, the crispy crust on the chicken doesn't stay as crunchy when doing this. It will soften as it sits on the pasta and sauce. This is why I bake the chicken separately in the oven, trying to retain that crispy coating on the chicken. Both ways of making this dish are delicious, it just comes down to preference.
