Ingredients for White Sauce Chicken Pasta Bake:

Pasta and Chicken with White Sauce is easy to make and will delight your family and friends. Here is what you’ll need:

Pasta: Feel free to use any shape (ziti, penne or rigatoni) and variety (classic, whole-wheat, gluten-free pasta) of pasta that you prefer. I like to use Rigatoni pasta when I can, it is great for baked pasta dishes, and holds up well to thicker sauces such as the creamy white sauce in this recipe. If you can’t find rigatoni at your local grocery store, penne is a good substitute.

Skinless chicken breast: Cut into bite size pieces and cooked.

Olive oil: For cooking the chicken.

Salt & spices: Ground nutmeg, ground ginger and black pepper.

Alfredo sauce (white sauce): My alfredo sauce recipe is a lightened up version- made simply with low-fat milk, little butter, mozzarella cheese, and all purpose flour.

Shredded mozzarella cheese: Feel free to use part-skim or full-fat.

Fresh spinach leaves: I used baby spinach.

Fresh mushrooms: cooked with the chicken, just until wilted.

How to Make Pasta with Chicken and White Sauce:

  1. Cook the pasta. Cook your pasta according to package instructions, just until tender.
  2. Cook the chicken. While the pasta is cooking, cook the chicken in a large skillet with salt and spices. Add mushrooms and baby spinach to the pan and cook some more, just until softened.
  3. Prepare the white sauce. To make the white sauce, just add milk to a sauce pan. Stir in some flour to thicken, add butter and cheese and bring to a simmer. Season with salt.
  4. Layer everything together. Once your pasta, sauce, and chicken are all ready to go, it’s time to combine the white sauce bake! In your pasta pot, stir together the pasta, alfredo sauce and chicken until combined. Then spread half of the pasta mixture out evenly in a 9 x 13-inch baking dish. Spread the the cooked on top . And repeat with the remaining pasta mixture, and sprinkle with shredded mozzarella cheese.
  5. Bake. Transfer the pan to the oven and bake for 20 minutes, or until the cheese is completely melted and has started to brown a bit on top.
  6. Add toppings. Remove and sprinkle with finely-chopped fresh parsley, if you’d like.
  7. Serve. Then dish it up while it’s s till nice and warm. Dig in and enjoy!

Tips for the Best Baked Chicken with White Sauce: 

This chicken chicken baked white pasta dish is a real crowd pleaser as-is, but there are so many ways to customize it. Here are some possible chicken alfredo variations:

  • Shred your own mozzarella cheese. If you want your cheese to melt well and stretch. Otherwise pre shredded cheese will taste just fine. 
  • For a different flavor, try using some pecorino romano or asiago cheese or parmesan.
  • This dish can be assembled up to 3 days before you plan to bake it. Store it in the refrigerator until you’re ready to put it in the oven. Bring to room temperature before baking. 
  • Make it spicy. If you like spicy food, sprinkle lots of crushed red pepper into (and on top of) this casserole to give it a bit of a kick.

Is Chicken Alfredo bad for you?

In a regular chicken alfredo recipe, I would say yes, chicken alfredo is not the healthiest. But in this recipe we are not using cream cheese, parmesan or heavy cream. This recipe calls for low fat milk, and 1 tablespoon of butter which can also be left out. So I can safely say that this chicken alfredo recipe is a heathier version ?

Can you Make Baked Pasta in Advance?

This pasta bake can be made in advance and refrigerated. It will be good up to three days in the refrigerator. To reheat it simply cover the pasta in aluminum foil and bake it at 350 F for about 45 minutes to reheat it in the oven.

Can you Freeze Baked Pasta?

Yes! The best part about this dish is that it’s great for meal prep! Can be frozen for up to 3 months. Tightly cover the top of your dish with foil, then cover everything with plastic wrap to get as tight of a seal as possible. Thaw it in the fridge over night before baking. You can also bake it from frozen, just add additional 20- 30 minutes of cook time.
