01 - Preheat oven to 375°F. Lightly grease a 9x13 inch baking dish.
02 - Boil ziti in salted water until al dente, approximately 8 to 9 minutes. Drain and set aside.
03 - In a medium bowl, blend ricotta, half of the shredded mozzarella, Parmesan, egg, garlic, basil, oregano, salt, and black pepper until smooth.
04 - Spread 1/2 cup marinara sauce on the bottom of the prepared baking dish. Arrange half of the cooked ziti over the sauce. Evenly spread half of the cheese mixture on top. Pour 1 cup marinara sauce over the cheese layer.
05 - Repeat layering remaining ziti, cheese mixture, and 1 cup marinara sauce. Finish with the remaining marinara sauce and sprinkle the remaining mozzarella evenly on top.
06 - Cover dish with aluminum foil and bake for 20 minutes. Remove foil and bake for an additional 10 to 15 minutes until cheese is golden and bubbly.
07 - Let rest for 10 minutes before serving. Optionally garnish with fresh basil.
