# Directions:
01 - Heat the oven to 375°F (190°C). Grease a 9x13-inch baking dish.
02 - Boil salted water in a large pot. Cook ziti until slightly firmer than al dente (about 2 minutes less than package instructions). Drain and set aside.
03 - In a saucepan over medium heat, warm olive oil. Sauté onion until soft, approximately 4 minutes. Add garlic and cook for another minute.
04 - Incorporate crushed tomatoes, tomato paste, oregano, basil, red pepper flakes if using, sugar, salt, and pepper. Let simmer uncovered for 10 to 15 minutes until sauce thickens.
05 - Combine ricotta, egg, Parmesan, and parsley in a bowl. Season with salt and pepper and mix thoroughly.
06 - In a large bowl, toss the drained pasta with half of the prepared tomato sauce.
07 - Spread half of the pasta mixture in the baking dish. Evenly dollop and gently spread half of the ricotta mixture over it, then sprinkle with half of the mozzarella.
08 - Repeat with remaining pasta, ricotta, and mozzarella layers. Pour the remaining sauce on top and finish with additional grated Parmesan.
09 - Cover the dish with foil and bake in the preheated oven for 20 minutes.
10 - Remove the foil and bake for another 10 to 15 minutes until the top is golden and bubbling.
11 - Allow the casserole to rest for 10 minutes before slicing and serving.
