    Frequently asked questions

    Can chicken alfredo bake casserole be made ahead of time?

    Yes, this makes a great make-ahead meal! Simply fully assemble it without baking, then cover and store it in the fridge for up to 2 days or freeze up to 3 months.

    How do I reheat a frozen casserole?

    To reheat, allow thawing in the fridge overnight then bake as directed.

    I don't like mushrooms, do I have to use them?

    No, feel free to replace them with additional broccoli or sliced bell pepper.

    Can I make this dairy-free, paleo, and/or whole30?

    Yes, you can! To do this, simply swap out the homemade alfredo with my paleo alfredo sauce. Then, top with dairy-free mozzarella cheese, or omit it for whole30 and strict paleo.

    The alfredo sauce

    For the keto alfredo sauce recipe, we're making a to-die-for super-rich and creamy homemade version - with cream cheese!

    Cream cheese isn't a typical alfredo sauce ingredient, but it really takes this dish to the next level in creaminess and taste.

    The alfredo sauce is super quick and simple to make. Here are the easy instructions:

    garlic sauteing in butter

    You'll start by melting some butter then add garlic and saute until it becomes fragrant.

    Then, slowly whisk in the heavy whipping cream and softened cream cheese cut into blocks. Be sure to soften it and cut it into blocks or it will take forever to melt!

    Then, stir in the shredded parmesan, salt, pepper, and a pinch of nutmeg.

    Bring to a light simmer and whisk until the alfredo is smooth and has slightly thickened, around 3 to 5 minutes.

    Easy instructions

    Place chicken breasts, broccoli florets, and mushrooms on a large, lined baking sheet. Then, drizzle everything with melted butter or avocado oil and season with sea salt, pepper, and Italian seasoning, including both sides of the chicken.

    Bake at 400 degrees for 20 to 25 minutes, or until the chicken is cooked through and the broccoli is tender.

    While that's baking, make the alfredo sauce. I highly recommend the homemade version because it's not only delicious, but it's also super easy!

    However, if you prefer, you can replace it with 1 ยพ cups of the store-bought variety. Just be sure to read the label carefully to ensure it's keto-friendly with no hidden sugar.

    When the chicken and broccoli are done cooking, let the chicken slightly cool, then chop or shred it with 2 forks and place in a large mixing bowl.

    Transfer mixture to the prepared baking dish and evenly sprinkle the top with mozzarella cheese. Bake for 10 minutes, or until the cheese is melted and browned.

    Top tips

    • To make this recipe dairy-free, paleo, and/or whole30, simply use my paleo alfredo sauce recipe (instead of the one in the recipe) and use dairy-free mozzarella cheese or omit it for whole30 and strict Paleo.
    • Feel free to replace the mushrooms with a bell pepper cut into 2-inch pieces or additional broccoli.
