- 3 cups Alfredo sauce (store-bought or homemade)

- ½ cup Parmesan cheese (grated)
- 1 cup heavy cream or milk (for extra creaminess)
- 2 tbsp butter
- 1 tsp garlic powder
- Salt and black pepper (to taste)
- Fresh parsley (for garnish)
Step-by-Step Instructions

1. Cook the Pasta
Boil the pasta until al dente. Don’t overcook because it will keep baking in the oven. Drain and set aside.
2. Prepare the Chicken
Use cooked chicken (rotisserie chicken works perfectly). Cut or shred it into small pieces so it mixes well with the sauce.
3. Mix the Sauce

In a large bowl, combine Alfredo sauce, heavy cream, butter, garlic powder, salt, and pepper. Stir well until creamy and smooth.
4. Combine Everything

Add pasta, chicken, and half of the mozzarella cheese into the sauce. Mix until everything is coated evenly.
5. Assemble the Casserole
Transfer the mixture into a greased baking dish. Sprinkle the rest of the mozzarella and Parmesan cheese on top.
6. Bake
Bake in a preheated oven at 375°F (190°C) for about 25 minutes or until the cheese is bubbly and golden brown.
7. Garnish and Serve

Top with fresh parsley before serving. Serve hot and enjoy the creamy, cheesy goodness!
