Creating the Olive Garden Five-Cheese Ziti al Forno can be straightforward if you follow these simple steps:

1. Cook the Pasta: Bring a large pot of salted water to a boil. Add the ziti pasta and cook until al dente according to package instructions. Drain and set aside.
2. Preheat the Oven: Preheat your oven to 375°F (190°C).
3. Prepare the Cheese Mixture: In a large mixing bowl, combine the ricotta cheese, egg, Italian seasoning, salt, and pepper. Mix well until creamy and smooth.
4. Combine Ingredients: In the same bowl, add the drained ziti pasta and half of the marinara sauce. Stir until the pasta is evenly coated.
5. Layer the Dish: In a 9×13-inch baking dish, spread half of the pasta mixture. Top with shredded mozzarella, provolone, and fontina cheeses.
6. Add Second Layer: Pour the remaining pasta mixture over the cheese layer, then top with the remaining marinara sauce.
7. Final Cheese Layer: Sprinkle the grated Parmesan cheese over the top. This will create a delicious, golden crust as it bakes.
8. Bake: Cover the dish with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden.
9. Rest: Once baked, remove from oven and let it sit for 10-15 minutes to set before serving. This allows the flavors to meld beautifully.
10. Garnish: Just before serving, sprinkle the dish with chopped parsley for a fresh touch.
