# Directions:
01 - Preheat the oven to 375°F. Grease a 9x13 inch baking dish.
02 - Boil salted water and cook ziti until just al dente, about 2 minutes less than package instructions. Drain and set aside.
03 - Heat olive oil over medium heat in a saucepan. Sauté chopped onion until soft, approximately 4 minutes. Add garlic and cook for 1 minute.
04 - Add crushed tomatoes, tomato paste, oregano, basil, red pepper flakes (if using), sugar, salt, and pepper to the pan. Simmer uncovered for 10 to 15 minutes until thickened.
05 - In a bowl, mix ricotta, egg, Parmesan, and parsley. Season with salt and pepper to taste.
06 - Toss drained pasta with half of the tomato sauce in a large bowl.
07 - Spread half of the pasta mixture into the baking dish. Dollop and gently spread half of the ricotta mixture over the pasta, then sprinkle with half the mozzarella.
08 - Repeat layers using remaining pasta, ricotta mixture, and mozzarella. Pour remaining tomato sauce on top and finish with extra grated Parmesan.
09 - Cover with foil and bake for 20 minutes. Remove foil and bake an additional 10 to 15 minutes until bubbly and golden brown.
10 - Allow the casserole to rest for 10 minutes before serving.
