Ricotta cheese (more or less depending on how cheesy you like it!)
Mozzarella cheese (I used shredded. Use whatever you like.)
One large egg (optional)
Grated Parmesan cheese or Parmigiano-Reggiano
1 pound box ziti pasta, cooked al dente and drained
Take a big mixing bowl, add the egg with a small container of ricotta, use a larger container of ricotta if you like, but then add another egg if you like. Mix some grated cheese in to the ricotta and egg and then mix the ziti noodles in to the cheese mixture. Coat the bottom of a large baking dish (9×13 dish) with some marinara. Put some of the ziti cheese mix on top. Sprinkle with some shredded mozzarella, then a little more of the sauce to cover. Another layer of the noodles, some more sauce, then layer the top with the rest of the mozzarella. Cover with sauce lightly and some thin slices mozzarella. Pile the rest of the ziti mixture on top of that layer. Bake at 350 until cheese has melted, bubbly and lightly beginning to brown.
