The term "al forno" is an Italian phrase that means "baked in the oven". When a dish is prepared "al forno" style, it typically means that it is baked in the oven until it is hot and bubbly, and sometimes topped with a crispy layer of bread crumbs or cheese. With my recipe, we are making things easy and skipping this step but feel free to cook your pasta further in the oven with a crispy bread crumb topping.
