Creating Five-Cheese Ziti al Forno is straightforward when you follow these steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Cook the Pasta: Boil a pot of salted water and cook the ziti according to package instructions until al dente. Drain and set aside.
3. Prepare the Sauce: In a large skillet, heat olive oil over medium heat. Add minced garlic and sauté until fragrant.
4. Add Tomatoes: Pour in the crushed tomatoes, oregano, basil, salt, and pepper. Simmer for 10 minutes, allowing the flavors to meld.
5. Mix the Cheese Filling: In a large bowl, combine ricotta cheese, half of the mozzarella, half of the provolone, Parmesan, fontina, and the egg. Mix until smooth and well incorporated.
6. Combine Ingredients: Add the cooked ziti to the skillet with the sauce and stir thoroughly to coat.
7. Layer the Dish: In a large baking dish, start with a layer of the ziti mixture. Then, add a layer of the cheese filling. Repeat the layers, ending with a ziti layer on top.
8. Top with Cheese: Sprinkle the remaining mozzarella and provolone on top of the final layer.
9. Bake: Cover the baking dish with aluminum foil and bake for 20 minutes. Remove the foil and bake for an additional 10 minutes or until the cheese is bubbly and golden.
10. Let it Rest: Once out of the oven, allow it to cool for about 5–10 minutes before serving.
