Cook pasta according to the directions on the package. NOTE: you can cook ziti halfway done. In this case use a bit more milk for the cheese sauce, so that pasta can continue cooking in the oven.
If you’re using long ziti break them in half to fit in the pot.
In the meantime prepare the five-cheese sauce.
In a pot add milk, fontina, emental, gorgonzola cheese cut in cubes, also ½ of the quality of shredded mozzarella and half of all grated parmesan cheese.
Set on very low heat and simmer for a few minutes until all cheese is melted. Stir continuously.
Grease a large casserole with butter.
Drain ziti and layer half of the quantity in the casserole. Cover with ⅓ of melted cheese sauce.
Drizzle with 2 tablespoons of breadcrumbs. Top with shredded mozzarella and grated parmesan cheese.
Place the second layer of ziti and repeat the process. Cover with cheese sauce, then breadcrumbs, then remaining cheese.
Bake in a preheated to 375F (190C) oven for about 15-20 minutes until a light golden brown crust on the top.
Notes
If you don't finish the whole dish in one go, just add some more milk and reheat ziti in the oven. They're absolutely delicious even the next day.
