Recipe FAQ

Yes, adding sautéed mushrooms or spinach provides extra vegetables and complements the dish's flavors.

How to achieve the perfect pasta texture?

Cook rigatoni slightly less than al dente before baking to ensure it finishes perfectly tender in the casserole.

What cheese combination is recommended?

A blend of shredded mozzarella and grated Parmesan creates a melty, flavorful topping with a golden crust.
