Cook pasta according to package instructions, cooking 2-3 minutes less than the package indicates.
16 ounces uncooked ziti pasta
Meanwhile, preheat the oven to 350°F.
In a large bowl, stir together the ricotta, egg, parmesan cheese, ½ the mozzarella cheese and the spaghetti sauce. Season with salt and pepper to taste. Depending on the variety of spaghetti sauce I use, I tend to omit any additional salt and pepper or add ¼ - ½ teaspoon of each if the sauce is plain
24 ounces ricotta cheese, 1 large egg, ½ cup grated parmesan cheese, 16 ounces mozzarella cheese, 32 ounces spaghetti sauce, salt and pepper
Once the pasta has finished cooking, strain and add to the bowl with the other ingredients. Stir well. Spoon into a 9x13” baking dish and sprinkle the top with the remaining mozzarella cheese and extra grated parmesan cheese, if desired
16 ounces mozzarella cheese
Cover with foil and bake for 30 minutes. After 30 minutes, remove the foil and continue baking 10-15 mins longer until the cheese is starting to brown and the ziti is bubbling.
Remove from the oven and let stand 10-15 minutes before serving
