Preheat the oven to 375°F (190°C).

Bring a large pot of salted water to a boil, then add the pasta and cook until al dente, about 8–10 minutes.

In a large mixing bowl, combine ricotta cheese, egg, 1 cup of shredded mozzarella, Parmesan cheese, Italian herbs, garlic powder, salt, and pepper.

Drain the pasta and return it to the pot, then stir in the marinara sauce until well coated.

Add the cheese mixture to the pasta and stir gently to combine.

Grease a 9x13 inch baking dish and transfer the pasta mixture, spreading evenly.

Sprinkle the remaining 1 cup of shredded mozzarella on top of the pasta.

Cover the dish with aluminum foil and bake for 20 minutes at 375°F (190°C).

Remove the foil and bake for an additional 10 minutes until the cheese is golden and bubbly.

Let the baked ziti rest for 10 minutes before serving.
