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
Ingredients
- Cooked Chicken: you can use diced or shredded. Leftover and rotisserie chicken work great!
- Cauliflower Rice
- Cheddar Cheese
- Cream Cheese
- Buffalo Sauce
The entire recipe and instructions can be found in the recipe card at the bottom of this post. You can also print the recipe from the card, if needed.
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 reference this post on How to Rice Cauliflower, if needed.
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 or Ranch dressing and fresh, minced parsley, if desired.
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.

Erica says
Hello there!! Is there anyway you can maybe make this in a crock pot/slow cooker? I’m looking for a dmix dump and go recipe that’s all ready for su after we get home from swim team practice! Do you think I can cube something chicken breasts, make recipe as you stated and throw all in the crock pot top w cheese and let her go for like 4 hours on low?? Let me know this sounds SO delish!! And my hubby hates cauliflower rice so trying to make something he will eat he loves Buffalo
Chicken lol thanks in advance for getting back to me 🥰
Lauren Vavala says
Hi Erica! Honestly, I’ve never tried this but this recipe is one ingredient different than most Buffalo Chicken Dips so I think it would work out just fine. The cauliflower rice shouldn’t take too long to get tender at all.
If you try it, let me know how it works out!
– Lauren
Melissa says
Hi, Erica
I realize your comment was from last year, but I just wanted to say if your hubby is still refusing the cauliflower, a great tip is mixing in some real rice as well.
It’s what I do with my kids, haha.
Cathie K says
This was really yummy! I had my 14 year old granddaughter make it while I gave her directions….she was so proud of herself, and more importantly, she really loved the dish!
Lauren Vavala says
Hi Cathie! This is such great feedback! I am so happy to hear that you and your granddaughter enjoyed the recipe!
– Lauren
Tammy says
Even my picky eater loved this dish. So easy and full of flavor. One of our favorites now.
Lauren Vavala says
Thanks so much!!
Randee says
Wow! Found this on Pinterest and it was so easy and so delicious!!!! Full fat cream cheese and sharp cheddar cheese made it very Keto friendly. Sprinkled the top with crumbled blue cheese.
Thank you for a dish that will be made again and again. 🙂
Lauren Vavala says
Thanks so much for the feedback Randee! Happy to hear that you enjoyed the recipe!!
Kristin says
How did you find out the portions? The ingredients are listed but doesn’t say how much of each product to use
Lauren Vavala says
Hi Kristin. The recipe card is at the bottom with amounts and instructions. That card is also printable, if needed.
Karen B. says
I have not yet tried this delicious sounding recipe, but I have a question. Could I use ground chicken or ground chicken sausage (I have a lot of it in my freezer) browned in non stick cooking spray?
Lauren Vavala says
Hi Karen! I haven’t ever made this with ground chicken, but I don’t see why it wouldn’t work. I usually dice the chicken pretty small or shred it anyway, so it’s similar. Obviously, the texture would be a bit different though. Let me know if you try it!!
– Lauren
Kirby says
Can I use quinoa if I don’t have enough riced cauliflower?
Lauren Vavala says
I’ve never made this with quinoa, so I’m not sure how it would work out. It will definitely affect the nutritional calculations so keep that in mind if you’re low carb/keto. The casserole might just be a tad bit creamier if you’re short on cauliflower and don’t replace it with anything 🙂
– Lauren
Marla Neely says
I wasn’t sure about this but I’m so happy that I decided to make it. I served it with a dollop of sour cream to cut the heat but it’s not necessary. I think this would be really great as a filling for so many things (taquitos and tacos come to mind) but from a bowl is also perfect!
Toni Sprouse says
This looks incredible and fits perfectly with my low carb lifestyle!!
Hope Hill says
This looks delicious! Cannot wait to make. I love cauliflower.
Adela says
5 stars my daughter in law made in Missouri last summner it was great now she is here so she make it again doubled the recipe. thanks for a great recipe
Lauren Vavala says
Great to hear! I’m glad you guys have been enjoying this recipe – it’s a personal favorite of mine 🙂
Alicia Warming says
Are you not supposed to cook the riced cauliflower at all?? It cooks while in oven with everything else?
Lauren Vavala says
Hi Alicia! Yep, the cauliflower rice will cook right in the casserole. It should be riced fairly small, plus its covered in hot, melted cheeses and sauce which help it to cook, as well. Hope this helps – Lauren
Alicia Warming says
Thanks so much! I am super excited to make this tomorrow, and just wanted to be sure I didn’t misread! 🙂
Lauren Vavala says
No problem! I hope you love it!!
Alicia Warming says
It was AMAZING! My boyfriend who is picky with vegetables loved it too and ate so much! And we still had leftovers — score! I bet it is even better heated up the next day. Will definitely be making this again soon!
Lauren Vavala says
Yay!! So glad the recipe turned out delicious for you guys! Thanks for stopping back to let me know 🙂 Lauren
Cynthia St Louis says
We loved this! I halved the recipe for the two of us. I used one bag of cauliflower rice and it did not seem to affect the consistency. We ate the entire dish- definitely a keeper!
Lauren Vavala says
Thanks for your feedback Cynthia! I’m glad that you guys enjoyed the recipe and that the frozen riced cauliflower worked out for you. It definitely makes things a bit easier and less mess 🙂
– Lauren
Maureen says
Turned out great! I did use frozen cauliflower just defrosted it then riced it. Not watery at all.
Lauren says
Thanks – glad to hear it!!
Stacey says
This recipe is really good and easy but im struggling calculating calories to be even close to 315 a serving..i know you said its just an estimate..im getting closer to 500? 🙁 maybe its for 8 servings and not 6? A block of cream cheese is 800, a block of cheddar is around 900 and 1.5lbs of chicken breast is around 1100. That alone is about 470 a serving split 6 ways. Am i missing something here? Thanks for the help!!
Lauren says
Hi Stacey! I’m so glad you said something. My recipe card is linked to a database for nutritional information. Basically, I plug in the ingredients and amounts and it has values already there. For some reason, the cooked chicken values were all blank. I just went in and used cooked shredded chicken instead. It’s giving me 1136 calories for the chicken, 914 for cheddar, and 776 for cream cheese so you are spot on. It’s all been updated but now shows 504 calories per serving. Thank you!
Alexa Verdade says
I was curious if you used low fat cream cheese or regular? thanks so much cannot wait to make this!!
Lauren says
Hi Alexa! I use full fat cream cheese. I haven’t tested the recipe with low fat so I can’t say how it would be different. I hope you enjoy it!!
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
Kyle says
Made this dish for my wife it was amazing we did have to end up cooking it twice as long because the cauliflower wasn’t cooking. Will be making it again!
Lauren Vavala says
Hey Kyle! Glad to hear you enjoyed the recipe. The cauliflower cook time might vary a bit depending on the side of the “rice.” I might have to adjust the time frame a bit to account for that. Thanks for the feedback, 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 Monica – 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 🙂
Jeni Morrow says
This dish was easy & delicious! I will make this again! Thanks for sharing! I will definitely be trying your other recipes! I’m so glad I found your site!
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
Jenni LeBaron says
