    Why you'll love this recipe

    There's a reason this dish is such a classic! Hashbrown casserole has always been one of my favorites and I'm guessing one of yours too! Actually, it's hard to find someone who doesn't like cheesy hashbrown potato casserole!

    Hashbrown casserole has been around for decades. It was mostly made famous by Cracker Barrel and has since been taken to many potlucks and BBQ's over the decades. I've even seen this dish go by the name of funeral potatoes! And now, even those who are gluten-free can enjoy their favorite potatoes!

    The original dish can easily be modified by just swapping out the cream of chicken soup with a gluten-free version, or so I thought. One year, I made that mistake for our family's Easter dinner. I subbed the canned soup for a gluten-free canned soup I had found at the grocery store. Little did I know, the soup had an odd flavor that completely overpowered the dish and totally ruined it! I was embarrassed, to say the least!

    Since that terrible experience with that gluten-free canned soup, I've decided to just ditch the canned soup altogether and make a simple gluten-free condensed soup from scratch. It only adds about five minutes to the recipe prep time but it makes a world of difference and will save a little money too! But of course, you can swap out the from scratch soup and still use your favorite canned soup in this recipe!

    If you love this recipe, you may also love this gluten-free corn casserole or gluten-free sweet potato casserole which are also great sides to feed a crowd! Also, check out this list of gluten-free potluck recipes to get some ideas for your next potluck!

    Ingredients

    Ingredients for gluten-free hashbrown casserole measured out in bowls.
    • Frozen Hashbrowns: Diced hash browns are preferred. Always check labels on frozen potatoes because not all of them are gluten-free.
    • Cheddar cheese: I prefer to shred my own cheese, but you can use pre-shredded if you like.
    • Homemade cream soup substitute: Rice flour or potato starch, butter, milk, and chicken stock are all that's needed for this!
    • Butter
    • Sour cream
    • Dried Minced Onion: Adds a huge flavor boost and is much easier than dicing an onion.
    • Crispy Rice Cereal: Arguably the best part of this casserole is the crunchy topping! Always look for gluten-free rice cereal because the name-brand Rice Krispies are not gluten-free. Aldi and Malt-o-meal sell gluten-free versions.

    Easy to Make

    First, make the gluten-free cream soup substitute, basically just a thick gluten-free white sauce. Then, just mix all the ingredients together and pour the mixture into a casserole dish. You don't even need to thaw the potatoes.

    Pro-tip: It is easier to mix everything but the potatoes first, then add the potatoes and mix them in last. Since they are frozen, sometimes they cause the mixture to freeze up too!

    Mixing ingredients in a large bowl, the mixture is in a casserole dish, spooning Crispy Rice cereal mixture on top.

    For the topping, melt a little more butter and combine with the gluten-free rice cereal. Spread over the top of the casserole. Then it's time to bake!

    Make It Ahead

    If you're prepping for the holidays or a party, you can make this casserole about one day in advance and keep it in the fridge.

    Pro-tip: Pull the casserole out of the fridge about one hour before you place it in the oven. If you place the cold casserole dish right from the refrigerator into a hot oven, it could crack.

    Just look at that crunchy topping! That has to be the best part!

      This was fabulous! I was so very leery of the cream soup substitute when getting ready to make this. I seasoned the soup substitute with S&P as stated in your recipe and then added about a tsp of dried thyme just because of being leery of flavor quality not having the canned soup. I had shredded hashbrowns on hand instead of cubed so I used those and my grocery store did not carry crispy rice gluten free cereal so I used gluten free crushed sea salt rice chips. none of these minor changes altered your recipe in any significant way and everybody loved this dish! I have always made hashbrown casserole with canned soup, but it was so much better with your soup substitute, I will always make it with the substitute from here on. thank you so much for another great recipe!

      Can I use cornstarch instead of potato starch? I am so excited to find a GF recipe for this casserole!

        Yes, that should be a fine substitution. The result should be thick, not soupy, so you may need to adjust the amount based on the final result. Hope that helps!

          Made this tonight with a few changes. I used cornstarch because I didn’t have rice flour or potato starch. Added 2 cups of cheese, some onion flakes and topped it with Parmesan. Next time I will make extra soup substitute (we like it creamier). It was delicious! Such a treat for my daughter, who is celiac. We will be making this a lot - great recipe, thank you for sharing it!
