    Dairy-Free Chicken Broccoli Alfredo Bake Ingredients

    With homemade Alfredo sauce and some other real food ingredients, it's time to get cooking. Here are the major ingredients you'll need:

    • Gluten-free penne pasta
    • Onion
    • Chicken breast or thighs
    • Frozen broccoli
    • Alfredo sauce
    • Garlic
    • Olive oil
    • Red chili flakes

    What type of chicken is best?

    Chicken breast and chicken thighs both work well here. Use whichever type of chicken you prefer.

    This is a great recipe for using what you have. Have leftover roasted chicken or rotisserie chicken? Skip the browning step and add the chicken in with the broccoli.

    Can I make the dairy-free Alfredo sauce ahead of time?

    Absolutely! Store the Alfredo sauce in an airtight container in the refrigerator. When you start to prepare the recipe, remove the sauce from the refrigerator so that it warms at room temperature.

    What's the best way to thaw frozen broccoli?

    The best way to thaw frozen broccoli is by placing it in a bowl and covering the florets with hot water. Allow the water to sit for a few minutes and then drain. Repeat this process if necessary.
