Creamy, cheesy, and easy to make, this Chicken Alfredo Bake is the perfect comfort food dinner. No need to pre-cook the pasta—everything bakes in one dish!
Preheat the oven to 375°F. Lightly grease a 9x13-inch baking dish.
In a large mixing bowl, combine uncooked pasta, milk, cream, Parmesan, 1 cup mozzarella, chicken, garlic, Italian seasoning, salt, and pepper. Stir everything together until well mixed.
Pour the mixture into the baking pan and spread evenly.
Cover tightly with foil and bake for 40 minutes.
Remove the foil, stir well, and sprinkle with ½ cup mozzarella. Bake uncovered for an additional 15 minutes, or until the pasta is tender and the top is bubbly and golden.
Let it sit for 5 minutes before serving. Sprinkle on fresh parsley if using.
Notes
No need to boil the pasta beforehand—it cooks right in the sauce as it bakes.
Use cooked chicken from leftovers or a rotisserie chicken for convenience.
Freshly grated Parmesan melts better and adds more flavor than pre-packaged.
If the pasta looks dry after baking, stir in a splash of warm milk or cream.
Add vegetables like spinach, peas, or steamed broccoli for extra color and nutrition.
This dish can be made ahead and stored in the fridge before baking. Just add an extra 5–10 minutes to the bake time.
