Deliciously Creamy Baked Chicken Alfredo

Our creamy Chicken Alfredo Bake turns my Slow Cooker Chicken Alfredo Pasta, Instant Pot Chicken Alfredo, and Chicken Bacon Ranch Casserole into an oven baked chicken alfredo casserole.

This alfredo pasta bake combines the convenience of cooked chicken and prepared penne with the creamy cheese sauce featured in my copycat Olive Garden Alfredo Sauce recipe, then bakes it in a casserole dish until brown and bubbly.

Alfredo chicken pasta is the perfect crowd-pleasing casserole that can be customized with different proteins or bulked up with veggies. So easy to assemble ahead of time, store in the fridge or freezer, and bake before feeding your family.

Why we love this Baked Chicken Alfredo Recipe

  • Quick and easy to make in under 30 minutes.

Chicken Alfredo Pasta Bake Substitutions and Additions

  • Choose Your Chicken: You can use a store bought shredded rotisserie chicken or cooked chopped or shredded chicken for this recipe.
  • Pick Your Pasta: I prefer to use penne pasta for my chicken Alfredo casseroles as it’s perfect for coating with cream sauce. Bowtie pasta, rotini pasta, or elbow pasta will also work well.
  • Change The Cheese: For a different flavor, try using some pecorino romano, asiago cheese, or your favorite freshly grated cheese instead of the parmesan.
  • Add Vitamin-Rich Veggies: Feel free to mix some vegetables into this dish, such as peas, spinach, kale, tomatoes, mushrooms, roasted red peppers, broccoli, or cauliflower.

Chicken Alfredo Bake Recipe Tips

  • If you are looking for a shortcut, you can opt-out of making your own sauce and use a store bought jar of Alfredo sauce! 
  • You can add a dash of chicken stock to the baking dish if needed when reheating.
  • You can add a little of the pasta water if needed to help bind and thicken the sauce.
  • Feel free to add crushed red pepper flakes to your chicken and Alfredo bake for a bit of heat.

How to store leftover Baked Chicken Alfredo

  • To Store: Leftovers can be stored in an airtight container or covered with tin foil in the fridge for up to 3 days.
  • To Freeze: You can freeze chicken Alfredo bake in a freezer safe container for up to 3 months.
  • To Reheat: Thaw overnight and reheat in the oven or microwave.

What to serve with Chicken Alfredo Pasta Bake

This pasta dish is a hearty, protein-packed meal on its own, but pairs perfectly with a simple side. Try serving it with some garlic bread, Easy Cheese Stuffed Garlic Rolls, Cheesy Pull-Apart Garlic Bread, or cauliflower breadsticks.

Another great addition to this dish is to start out with a garden salad or to serve some roasted veggies, Broccoli Salad, or green beans on the side.
