Cook the ziti pasta according to package instructions until al dente. Drain and set aside.
In a large mixing bowl, combine the ricotta cheese, half of the mozzarella cheese, egg, olive oil, garlic powder, oregano, salt, and pepper. Mix well until combined.
Stir the cooked ziti into the cheese mixture until the pasta is fully coated.
Spread half of the marinara sauce at the bottom of a 9x13-inch baking dish.
Add the ziti and cheese mixture on top of the sauce, spreading it evenly.
Pour the remaining marinara sauce over the ziti, then sprinkle with the remaining mozzarella and the grated Parmesan cheese.
For an extra kick, sprinkle crushed red pepper flakes on top (if using).
Cover the baking dish with aluminum foil and bake for 25 minutes.
Remove the foil and bake for an additional 15 minutes, or until the cheese is bubbly and golden.
Once baked, allow the dish to cool for a few minutes before serving. Garnish with fresh basil leaves.
Notes
