Cook the Pasta

• Bring a large pot of salted water to a boil.
• Add fettuccine (or your chosen pasta) and cook until just shy of al dente, as it will finish cooking in the oven.
• Drain and set aside.

Prepare the Alfredo Sauce

• Use store-bought Alfredo sauce for convenience or make it from scratch.
• To make it, simmer heavy cream, Parmesan cheese, butter, and minced garlic over low heat until creamy and smooth.

Combine Ingredients

• In a large mixing bowl, combine the cooked pasta, Alfredo sauce, heavy cream (optional), shredded chicken, garlic powder, Italian seasoning, and a pinch of salt and pepper.
• Mix well to coat the pasta and chicken evenly.

Assemble the Casserole

• Preheat your oven to 375°F (190°C).
• Lightly grease a casserole dish.
• Pour the pasta mixture into the dish and spread it evenly.

Add the Cheese Topping

• Sprinkle mozzarella, Parmesan, and cheddar cheeses evenly over the pasta.

Bake the Casserole

• Place the casserole in the preheated oven.
• Bake for 20–25 minutes or until the cheese is melted, bubbly, and slightly golden on top.

Garnish and Serve

• Remove the casserole from the oven and let it cool for a few minutes.
• Sprinkle freshly chopped parsley on top for garnish, if desired.

Serve warm and enjoy!
