Ingredients
Method
- Set your oven to 350°F (175°C) and let it warm up.

- In a spacious bowl, stir together the pasta, the seasoned chicken, Alfredo sauce, mozzarella, Parmesan, and peas until evenly blended.
- Pour this mixture into a greased 9×13-inch casserole dish, smoothing the top out.
- Add a sprinkle of mozzarella and Parmesan over the surface to create a cheesy crust.
- Place the dish in the oven and bake for about 25 to 30 minutes, or until the cheese is bubbling and has turned a nice golden color.
