Being the food-loving blogger that I am, a restrictive diet can be really challenging. Food needs to taste good. Really good.
The idea for this Creamy Buffalo Chicken Cauliflower Casserole had been a long time coming. I was inspired to make this simple dinner recipe by my love for any and all things made with Buffalo sauce – especially Buffalo Chicken Dip. Because the sauce has 0 calories, and therefore 0 carbs, it’s a great condiment to use to add big flavor!
In fact, I love Buffalo sauce so much that it has inspired quite a few other recipes! Bacon Wrapped Buffalo Chicken Poppers, Buffalo Chicken Pizza, and Buffalo Chicken Salad are three more low carb recipes where Buffalo chicken is the star!
Why This Recipe Works
- 5 ingredients is all it takes to make this super flavorful casserole dish!
- Cream cheese is blended with a sharp cheddar cheese for a smooth, creamy base.
- Classic Buffalo sauce brings plenty flavor and spiciness.
- Cauliflower rice is used in place of regular rice to reduce the carbohydrates. Chunks of chicken add plenty of protein making this casserole suitable for those on low carb or keto diets.
- This recipe is naturally gluten free.
How to Make Buffalo Chicken Cauliflower Casserole
Prep!
Set the cream cheese out to come to room temperature about an hour before you begin to make mixing a bit easier. You can skip this step, but the casserole mixture will be harder to combine.
Dice and cook your chicken, or shred it, if preferred. Leftover or rotisserie chicken works great for this recipe! I also like to use my Instant Pot to cook the chicken which makes it super easy to dice and shred.
Rice the cauliflower. I recommend using fresh cauliflower, when possible. Using frozen may give you a runnier sauce. You can rice the cauliflower by using a grater or by adding the florets to a food processor and pulsing a few times until it resembles rice.
Shred the cheddar cheese. It is not recommended to use a bagged shredded cheese as it contains a starch to keep it from sticking together. That starch makes it so the cheese doesn’t melt as nicely and increases the carb count of this Creamy Buffalo Chicken Cauliflower Casserole recipe.
Preheat your oven to 375°F.
Create!
In a large bowl, combine the chicken, riced cauliflower, buffalo sauce, cream cheese, and half of the cheddar cheese. The mixture will be thick.
Spread into a medium casserole dish.
Top with the remaining cheddar cheese.
Cover loosely with foil and bake for 25 minutes. Remove the foil and bake for an additional 10 minutes or until the cheese is melted and bubbling.
Present!
Top the Creamy Buffalo Chicken Cauliflower Casserole is with extra Buffalo sauce and fresh, minced parsley, if desired.
Enjoy!
Tips and Techniques for the Best Creamy Buffalo Chicken Cauliflower Casserole
- Setting the cream cheese out to come to room temperature an hour before you begin will make it easier to combine all of the ingredients.
- Cut the chicken into bite size cubes and cook in a skillet with olive oil until just done through, or use an Instant Pot, or use leftover or rotisserie chicken to save time.
- It is best to shred the sharp cheddar cheese from a block rather than buying a bag of pre-shredded cheese which contains a starch and doesn’t melt as well.
- I recommend using fresh cauliflower, when possible. Using frozen may give you a runnier sauce. You can rice the cauliflower by using a grater or by adding the florets to a food processor and pulsing a few times until it resembles rice.

Keely Langer says
I was wondering about using just cauliflower florets? Do you think it would work if I steamed them a bit first?
Lauren says
Hi Keely! That should work. I would make sure to cut them bite-size and steam until just fork tender – or they may get super soft and fall apart (unless you want that result 🙂 Hope you love this recipe!! – Lauren
Brittany says
Made this tonight and it was a hit!! I also used frozen cauliflower rice and It was the perfect consistency! I cooked it as the package said on medium heat in a nonstick skillet for 5 minutes then I patted dry to make sure there wasn’t excess moisture!
Lauren says
Hi Brittany! Thanks so much for the tips on using frozen cauliflower 🙂 Glad the recipe turned out great for you! – Lauren
Kelsey says
Loved this! I boiled my chicken, and used frozen cauliflower because I’m lazy and it was perfect!
Lauren says
Glad to hear you loved it!!
Mindy says
Delicious! I used two steamable bags of frozen riced cauliflower cooked a couple of minutes to thaw. I browned the chicken in a little olive oil, then melted the cream cheese into the hot chicken and mixed it all up in a big bowl. When it came out of the oven it was kinda soupy (more like oatmeal), but as it cooled it thickened up some. A little high on sodium. This is going into my keto rotation!
Lauren says
Hi Mindy – I need to add a little tip to use fresh cauliflower if possible. I have had other people say they have used frozen with good results, but I tend to get a “soupier” result with frozen vs. fresh. I think the sodium is coming from the cheese, but it does seem high – I’ll recheck the calculations to see if the information it gave me is a little off, or if that’s actually correct. Thanks for coming back to comment and rate the recipe – I appreciate it! Lauren
Susan says
When you say to “rice the cauliflower”, what exactly does that entail?
Lauren says
Hi Susan! I’m sorry – I’ve been trying to explain this in any posts that use riced cauliflower, but I have yet to add it here. You can buy riced cauliflower from some grocery store produce departments, or rice it yourself with a grater or by putting cauliflower florets in a food processor and pulsing a few times until it resembles rice. I hope this helps – Lauren
Traci says
I too added some celery. Excellent dish!!
Laura says
Hi,
What is the serving size? 1 cup?
Thanks.
Lauren says
Hi Laura – nutritional information is only an estimate and based on 1/6th of the recipe. It’s not a measurement based on exact cups etc. since that is extremely hard to do especially just out of a home kitchen. Thanks for understanding 🙂
Jenny says
Does the rice cauliflower need to be precooked? Seems like raw cauliflower wouldn’t have time to cook in that much time. 😊
Lauren says
Hi Jenny! I don’t precook the cauliflower and haven’t had any issues with it being raw still. I would say just to make sure when you process/rice it to make it more rice-sized – sometimes the pre-riced cauliflower can be bigger and if so, you may want to add a few minutes to the cook time.
Monica says
How much is one serving? A cup? Half a cup?

Lauren says
Hi Jeni! SO happy to hear you enjoyed the recipe! Thanks for coming back to let me know – I hope you find more to try 🙂 Lauren
Sarah says
Very yummy! I added a little extra hot sauce, craving that kick I guess. I used neufchatel instead of cream cheese. I also was a little short on cheddar so topped it with colby. I also used frozen riced cauliflower which made this an incredibly easy casserole and one that could work for a weeknight. Delish, thanks!
Lauren says
So happy to hear you liked the recipe! Glad to hear frozen cauliflower worked out too!
Alli says
This is a great recipe, I used reduced fat cream cheese & Cabot 50% less fat sharp cheddar cheese & it was still delicious!
Lauren says
So glad to hear you love the recipe! Thanks for the info on the results with different cheeses and for rating the recipe too! 🙂 Lauren
MaryAnne says
4 STARS!!! This is so easy and so delicious. I cooked some chicken breast in my instant pot and chopped them up and I added 2 stalks of chopped celery for some crunch. I served it with extra Franks hot sauce and crumbled blue cheese on the side. So yummy and such a hit with my boys. Great for leftovers too…make extra for lunch the next day with a salad!
Lauren says
SO glad to hear you love it! This is one of my family’s favorite so we rarely have leftovers – I had to make a Buffalo Chicken Salad recipe on it’s own hahaha! I appreciate you coming back to let me know how it went and for rating the recipe 🙂 – Lauren
