    • Chicken Alfredo Casserole
    A close-up of a plate of chicken parmesan casserole. The casserole is topped with a golden brown breadcrumb crust and is served on a plate with a decorative pattern. A fork, spoon, and a piece of bread are visible in the background. This recipe is part of a chicken alfredo casserole recipe.

    Ingredients

    The ingredient list is so simple for this meal! All you need is:

    • Fettucine or spaghetti noodles
    • Cooked, diced chicken
    • Chicken broth
    • Whipping cream
    • Parmesan cheese
    • Butter
    • Flour
    • Pepper

    Please note that this recipe is NOT one of our usual 5 ingredient or less recipes. Make sure to check out our huge list of 5 ingredient or less casserole recipes!

    Instructions

    • Cook noodles according to package directions. Drain and set aside.
    • In a large saucepan, melt the butter. Whisk in the flour and seasonings. Cook over low heat stirring constantly until the mixture becomes smooth and bubbly. Remove from heat. Stir in broth and cream.
    • Return to heat, turn heat up to medium and continue stirring constantly until mixture comes to a boil. Boil for one minute. Turn heat off, stir in chicken and noodles.
    • Pour the mixture into a lightly greased 9x13 or 11x14 inch pan. Sprinkle parmesan cheese evenly over the top of the casserole. Bake casserole at 350 degrees for approximately 10-15 minutes, or until the center is bubbly and cheese on the top is lightly browned.
    • Fast option: If the casserole is still warm, I'll just put the casserole under the broiler for a couple of minutes until the cheese on top is browned.

    Substitutions

    It's very simple to make this casserole for a variety of different dietary preferences or needs!

    • Gluten free chicken casserole: Substitute gluten free fettucine noodles. You will also want to use a gluten free flour.
    • Dairy free: To make this recipe dairy free you will want to substitute dairy free heavy whipping cream, dairy free butter, and dairy free parmesan cheese.
    • Vegan chicken casserole: To make your casserole vegan, omit the chicken or use plant based chicken breasts and use plant based butter, plant based heavy whipping cream, and plant based parmesan cheese. You will also want to use vegetable broth instead of chicken broth.

    Tips

    • Use grated parmesan: Grated parmesan adds a nice crispy crust on the top of the casserole.
    • While diced chicken breasts are classic, you can substitute with shredded rotisserie chicken, turkey, or even shrimp for a twist. You can also substituted chopped vegan chicken breasts.
    • Since the casserole will bake in the oven, cooking the pasta to al dente ensures it won’t become mushy.
    • Enhance the casserole with cooked broccoli, spinach, or mushrooms for added flavor and nutrients.

    Storing

    Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through.

    Reheating

    You can reheat your chicken alfredo casserole by reheating it in the oven at 350°F (175°C), covered with foil, until heated through. Add a splash of milk or cream if needed to restore its creamy consistency.

    FAQ

    Can I use a different type of pasta?

    Yes! While fettuccine and spaghetti work well, you can substitute with any pasta shape you prefer.

    What can I use instead of heavy whipping cream?

    You can substitute with half-and-half or whole milk. We have even used part heavy whipping cream and 2% milk when we've been in a bind and it works great!

    Can you freeze the chicken casserole?

    Absolutely. Assemble the casserole but do not bake it. Wrap it tightly in plastic wrap and aluminum foil, then freeze for up to 3 months. Thaw overnight in the refrigerator before baking. Please note that it might change the texture of the casserole as cream based products may separate slightly when frozen.
