    Instructions

    Steps to make the homemade sauce for chicken casserole.
    • Preheat oven to 375°. Lightly grease a 9×13-inch casserole dish and set aside.
    • Melt dairy-free butter in a large skillet over medium heat. Add the onions and heat for 4 minutes, stirring frequently. Then, add the crushed garlic and cook for an additional minute. 
    • Next, mix in the gluten-free flour, stirring constantly. Cook for 1 minute, then slowly the almond milk a little at a time, stirring to keep it smooth as it thickens. 
    • Stir in the nutritional yeast, sea salt, and Herbamare.
    • Slowly add 2 cups of the chicken broth. Stir frequently and cook for 2-3 more minutes. Then turn off the heat and let sit.
    Steps to construct the casserole.
    • Place the rice in a metal strainer and run under cold water for a few minutes to rinse off excess starch. Then, pour the rice into the prepared casserole dish. 
    • Spread the broccoli over the rice.
    • Place the chicken evenly over the broccoli. Pour the remaining 2 cups of chicken broth over the chicken.
    • Next, pour the homemade sauce evenly over the casserole. Press any rice or broccoli that might have popped up under the sauce.
    • Cover the casserole dish with aluminum foil and bake for 60 minutes.

    Storage

    Leftovers should be stored in the refrigerator for 3-4 days. The leftovers can also be frozen for up to 3 months. I like to freeze individual portions to have easy meals on hand. That way, you can take out however many you need at a time.

    To thaw, place the frozen casserole in the refrigerator overnight. To reheat, place in an oven-safe dish and cover with foil. Heat in a pre-heated 350° oven for 15-20 minutes until heated through. You can also reheat it in a microwave if preferred.

    Notes

    For the dairy-free butter, I used Country Crock Plant-Based Butter.

    For gluten-free flour, I used Pamela’s All-Purpose Mix.

    You can use chicken breast or chicken thighs or a combination of both to equal 2 pounds. Personally, I prefer all chicken breast.

    I purchase my Nutritional Yeast and Herbamare on Amazon.  

    The dishes I used in this post are a non-stick Caraway 12-inch skillet and a 9×13-inch deep dish casserole dish.
