Buffalo Chicken Casserole

Craving something extra? My new Buffalo Chicken Casserole is a show stopper and will help bring boring chicken to life. This recipe is full of flavor and amazing texture. In addition, it is Whole30, Keto and Paleo compliant. Healthy has never tasted so good!

Buffalo Chicken Casserole

When I create recipes, I always think about my husband. Taking his pallet into consideration allows me to create “man approved meals” that is not only overflowing with flavor, but is also healthy and filling. When I served this recipe to my husband, it easily became his favorite and even one he requested on a consistent basis.

Buffalo Chicken Casserole

This recipe is filled with a ton of flavor that will keep you going back for more. In addition, it is an amazing option for meal prep. I will throw this in a glass storage container and serve with a side salad drizzled with some red wine vinegar, light olive oil and a little lemon juice.

Tips for making this Buffalo Chicken Casserole:

  • I buy the frozen cauliflower rice at Sam’s Club in the freezer section. I highly suggest buying pre-made frozen cauliflower rice and just adding it in frozen. It really will save a ton of time.
  • Make sure not to over bake because it could possibly dry it out.
  • If you don’t want to make my homemade Mayo or Ranch, then you can buy other compliant brands such as, Primal Kitchen or Tessemae

Can you freeze this Buffalo Chicken casserole?

Absolutely! Simply transfer the entire casserole (except for the garnish) to an airtight container or individual meal prep containers and place in the freezer. They store well for 3 months!

Buffalo Chicken Casserole

Buffalo Chicken Casserole

A creamy Buffalo Chicken Casserole that is Whole30, Keto and Paleo compliant. Filled with shredded chicken, mayo, ranch, nutritional yeast, seasoning, green chilies and Franks Hot sauce. A perfect easy and quick weeknight dinner. 

  • Total Time: 42 minute
  • Yield: 4-5 1x


  • 2.5 lbs cooked chicken breast (4 1/2 cups, shredded)
  • 3 1/2 cups cauliflower rice (frozen or raw)
  • 1/2 cup Franks Hot Sauce
  • 2 tbsp compliant ranch dressing
  • 1/3 cup compliant mayo
  • 1/2 cup chopped white onion
  • 1/3 cup green chilies or sub chopped banana peppers 
  • 1/3 cup chopped green onions
  • Garnish with additional green onions and drizzle with 2 tbsp of ranch and a more hot sauce. 



  1. Preheat oven to 350F.
  2. Coat a 9X9 or a 9X13 baking dish with olive oil.
  3. In a large bowl, add the cauliflower rice, onions, green onions, banana peppers or green chilies, cooked shredded chicken, Franks Red Hot Sauce, mayo, ranch, nutritional yeast and the rest of the seasoning. 
  4. Mix all the ingredients together until completely combined. 
  5. Transfer the mixture to the baking dish and add to the oven. 
  6. Bake for 35-40 minutes or until the top is crispy and bubbling. 
  7. Drizzle with ranch, top with fresh chopped green onions and add a little more Franks Hot Sauce to the top.
  8. Enjoy!


  • Be sure to check the ingredients for the banana peppers for compliant ingredients. I love buying mine through Thrive Market, which is compliant for the Whole30 program. 
  • You can add in the cauliflower rice in frozen or raw. You do NOT have to cook it before adding it to the oven.
  • This will last in the fridge up to one week and in the freezer for 3 months.

    1. Ashley McCrary says:

      WOW! This makes me so happy. Thank you, Betsy!

  10. Jen says:

    Mine is in the oven as we speak! Was I supposed to pre-cook the cauliflower rice? I used riced raw cauliflower that I bought fresh from the store. I hope it’s not too crunchy lol.

    1. Ashley McCrary says:

      No you do not have to precook. I have included that in the recipe notes.

      1. Rebecca says:

        Hi there – excited to make this dish! Can I use white rice? Should I pre-cook?

        1. Ashley McCrary says:

          Yes you can sub white rice and I would pre-cook it.

  11. Tina says:

    This looks so delicious. Have it down to try. Thanks for all your hard work.

  12. Ellen says:

    LOVED trying this recipe tonight! I’ve had lots of fails in the past with cauliflower rice, I was a little nervous trying, but I figured you couldn’t go wrong with lots of ranch and hot sauce! This tasted amazing and my husband loved it too 🙂 Thanks for all your yummy, simple, and budget friendly recipes!

    1. Ashley McCrary says:

      This makes me so very happy to hear. Thanks for leaving a review.

  13. Nanette says:

    This recipe is delicious! Made it for dinner last night and leftovers today. I ate it on a baked sweet potato, with some of your ranch, soooo yummy! It was my first time trying cauliflower rice. You’ve made my whole 30 so much easier with ALL of your amazing recipes!

  14. Caitlyn says:

    This casserole was AWESOME! Really tasty and filling. I halved the recipe because I didn’t need a large pan of it and it came out great! I love the flavors and would think you could use this in other ways since it sort of has the consistency of a dip- I think on a pizza crust with cheese or in a taco.. or a lettuce wrap!

    1. Ashley McCrary says:

      Yay! So glad you like it. Yes, you could absolutely use it as a dip too.

  15. Any Hobbs says:

    Do you have to use the yeast?? What does it do or it’s purpose.

    1. Ashley McCrary says:

      You do not have to, but it does give the casserole a cheesy and nutty flavor.

      1. Jess says:

        Could you sub out the nutritional yeast for cheddar if you’re doing a keto plan?

        1. Ashley McCrary says:

          Sure, that would be great.

  16. Patricia says:

    Loved this! My twins and my older girls even enjoyed it.

    1. Ashley McCrary says:

      This is so awesome to hear. Thank you for sharing

  17. Adrienne Everding says:

    My family really enjoyed this recipe! It was tasty, comforting, and filling at the same time. To add a little texture, I added parmesan crips that I crumbled to the top. I liked the added crunch. This will definitely be added to our meal rotation.

    1. Ashley McCrary says:

      Hi Adrienne. My mom has to have that crunch factor too. Totally understandable. So glad to know the family was on board. Means a lot to know that my recipes are helping make family memories. Thanks for sharing your kind review!! Blessings your way;-)

  18. Katie Askren says:

    I love this buffalo chicken casserole! I have made this recipe twice now during my Whole30 and my husband and I both love it! The first time I used green chilies and the second time banana peppers. Both ways were delicious, but I think I like it with green chilies the best. I have also made several other of Mac’s recipes and I have loved them all!

    1. Ashley McCrary says:

      Look at you tweeking the recipe to make it your own;-) Love that!!!!! So thrilled to know this recipe was a hit. Thanks for your kind review;-)

  19. Deanna says:

    This is such a great go to dinner or lunch for me at work! So easy to reheat and transfer. Thanks!

    1. Ashley McCrary says:

      Hi Deanna. So glad to know this healthy recipe is a game changer for you. It really is a great meal to reheat and enjoy. Thanks so much for your kind review:-). Blessings your way!

  20. Mariah says:

    I’ve made quite a few of your recipes and loved them all, but this one is especially delicious. It’s so easy and reheats fabulously. I’m adding this one to my monthly rotation for sure!

    1. Ashley McCrary says:

      YAY…….I am thrilled to have made the rotation;-). It really is a fun recipe that adjusts nicely to reheats. Thanks so much for your kind review Mariah;-). Blessings your way!

  21. Tara Kreuger says:

    Another winner! We have added this to our monthly rotation. So yummy! Thank you for all of your delicious recipes!!

  22. Lana says:

    We love buffalo chicken in our house and are always looking for different recipes to try. This one does not disappoint! I love that it freezes well too so I can freeze the leftovers as “meal prep” for days that I’m working. It’s also good hot or cold which is great for days that I’m eating a few bites here and there on the run as a busy ER nurse!

    1. Ashley McCrary says:

      Hi Lana…….first of all thank you for what you do in the ER! Oh my goodness, your service is so so needed and is not always seen as important. It takes compassionate nurses to make the sometimes scary ER visits a game changer.
      Thank you for your kind food review comments. Looks like this recipe meets so many of your busy lifestyle needs. So so happy I could help:-)

  23. Stephanie B says:

    This recipe is simple and hearty! I used a rotisserie chicken to save myself some time in the kitchen. Great flavor and texture!

    1. Ashley McCrary says:

      I am so happy to hear you liked it. Thank you

  24. TARA says:

    Loved this recipe! Super easy! Always looking for great Whole30 recipes that both my husband and I will like.
    A winner! Thank you! xo

    1. Ashley McCrary says:

      Awwww, thanks Tara. Isn’t if so fun to find recipes that fit both of your tastebuds? So glad I could help build your Whole30 favs;-)

  25. Aly says:

    Made this the other night for my boyfriend and we were IN LOVE. I did sauté the onions a little first and did half rice/half cauliflower rice (for an extra full feeling).

    Always love your recipes and ideas. Thank you so much for sharing!

    1. Ashley McCrary says:

      YAY!!! Thanks so much for your kind words Aly!!!! So glad to know Im working to create recipes that you love and fit your lifestyle:-)

  26. Ashley says:

    So fast and easy and the flavor is great! Definitely will make again.

    1. Ashley McCrary says:

      Thank you so much!

      1. Lauren says:

        This was so good and so easy to put together! I think next time I might add some chopped celery to add a little extra crunch. This is definitely going to be in my regular rotation. Thank you!!

        1. Ashley McCrary says:

          SO happy to hear. Thank you Lauren!

  27. Christy says:

    I cheated w/ rotisserie chicken, but this is AMAZING! It was part of weekly meal prep & we had for dinner tonight! ❤️❤️❤️

    1. Ashley McCrary says:

      I am so happy to hear this. Thank you so much

  28. Erica says:

    If you like chicken with a kick, this is the one for you! Even better reheated the next day!

    1. Ashley McCrary says:

      Thank you so much!

  29. Kristin says:

    Do you have a specific recipe or preferred way of shredding the chicken for this recipe??

    1. Ashley McCrary says:

      I usually just shred with a fork. You can also you a stand mixer to shred your chicken.

      1. Kristin says:

        Whoops, I meant to ask for a recipe for how to prepare the shredded chicken but I ended up boiling it and then using your recommendation of the stand mixer. This is the first paleo recipe I’ve ever attempted and WOW! It’s so incredibly good! I used primal foods mayo and your homemade ranch recipe! This will last us several days, then we plan on trying your recipe for ranch roast next.

        1. Ashley McCrary says:

          I am so happy to hear you loved this one. I hope you enjoy! Thank you for giving them a try.

  30. Yvonne Campbell says:

    Everyone loved this!!! It was so so good. Definitely going to have this again. I put some sour cream on it to cut through the heat. Very good.

    1. Ashley McCrary says:

      Thanks so much Yvonne……..thrilled it was a hit

  31. Sue says:

    This looks amazing!! I’ll have to put this in our menu plan for an upcoming meal!

    1. Ashley McCrary says:

      Thanks Sue………let me know what ya think! Have a blessed weekend!

  32. Kelly says:

    So easy and yummy!!!

    1. Ashley McCrary says:

      Easy and tasty is certainly my passion. Thank you Kelly!!

  33. Lauren says:

    Is there a sub for the nutritional yeast? We can’t have folic acid, which nutritional yeast is fortified with.

    1. Ashley McCrary says:

      Nutritional yeast is what gives it the cheese flavor. You could sub cheese or even dairy free cheese. Maybe a 1/2 cup or so.

  34. Anna says:

    This is AMAZING!!!!

    1. Ashley McCrary says:

      Thank you so much.

  35. Michelle says:

    This was amazing! I’ve been wanting to try it for a while, but my husband doesn’t like cauli rice. We ate 2/3 of the casserole 😂
    I would maybe saute the onion and cauliflower rice a bit just to reduce the crunch, but that’s a personal preference.

    1. Ashley McCrary says:

      Thank you so much.

  36. Kim says:

    I haven’t made this one yet, but I just made the Buffalo chicken meatballs and they were a game changer. I really have a mayo aversion…is it for texture or can you taste it in this dish? Any recommended substitutions? Thank you for all the recipes – it’s saving us in lockdown!

    1. Ashley McCrary says:

      Hi Kim, you honestly can’t taste it in the dish. Really just makes it creamy.

  37. Lauren says:

    My family LOVES this recipe! Even my 4 year old eats this up and asks for more, it doesn’t last long in our house lol. We do have to omit the nutritional yeast because I can’t have folic acid, but otherwise we follow the recipe as written and its perfect everytime. Thanks for this!

    1. Ashley McCrary says:

      This comment made my day. Thank you

  38. Linda says:

    Absolutely delicious! Family approved too! Thank you for creating and sharing!

  39. Amber says:

    This casserole is amazing!! I following the recipe exactly. My kids love it also! This recipe is perfect for meal prep and gets even better as it sits.

    1. Ashley McCrary says:

      This is so awesome to hear. Thanks a bunch

  40. Stephanie says:

    Great recipe! Will make again! Thanks

    1. Ashley McCrary says:

      Thank you

  41. Kim Roehricht says:

    I have all of the ingredients and making it tonight! Thank you!

    1. Ashley McCrary says:

      Yay! Hope you love it

  42. Abbey says:

    Can the nutritional yeast be left out?

    1. Ashley McCrary says:

      You can leave it out, but it is what give it a “cheesy” taste.

  43. Heather Germershausen says:

    This recipe is the Lol!! Super easy, delicious and healthy. We have eaten it on sweet potatoes and Siete chips. I don’t even miss the cheese and I’m a recovering cheese a holic. Thanks for another great recipe ❤️

    1. Ashley McCrary says:

      Awww thanks Heather……Thrilled you loved this recipe!!!!! Hope it becomes a family favorite. Have a blessed weekend.

  44. Ashly Huff says:

    Really like this recipe! Simple to make, delicious and my boyfriend didn’t even realize he was eating something healthy! I added a chopped yellow pepper because I prefer those over green chiles or banana peppers, and loved the taste. This will be in our usual rotation!

    1. Ashley McCrary says:

      YAY! This made my day

  45. D Aragon says:

    Do we need to add the nutritional yeast??? Or could we make without?

    1. Ashley McCrary says:

      The nutritional yeast adds the cheesy tastes…… do not have to add!!

  46. Jessica says:

    Can you substitute the Mayo with anything?

    1. Ashley McCrary says:

      Hi Jessica,

      To stay Whole30 compliant you really can’t BUT if you are not completely compliant then you can substitute the mayo with either sour cream or cream cheese. Have a great weekend.

  47. Jessica Feist says:

    Do you have any whole30 compliant swaps for the Mayo? I have an egg allergy and can’t do the whole30 Mayos since they contain egg. I know Kite Hill makes a sour cream. Do you think that could be a good swap?

    1. Ashley McCrary says:

      You could for sure try that. It will give it that creamy texture. It may taste slightly different, but I still think it would be yummy!

  48. Marybeth says:

    This is one of our absolute favorites – especially on a Whole30. We love to eat it with siete chips – almost like a dip. Super filling, super easy and super versatile. We make this at least once a month.

  49. Kayla says:

    Simple to make and soooo good! I make this recipe at least once a month.

    1. Ashley McCrary says:

      Thank you so much! So happy to hear it’s a hit

  50. Kristen says:

    This recipe is a winner! Easy to throw together and so flavorful. I used ground chicken as it’s what I had on hand and it worked out great.

  51. amy says:

    hi!! If I freeze this should I cook and then freeze it?

  52. Kristin Pikop says:

    Can this be made with hash browns?

  53. Stephen E KC says:

    Greta meal but prep time is 45 minutes. You have to cook the chicken first!!! We didn’t eat till 8:30 because dad thought it would be ready in 50 minutes but add 45 at least to that

    1. Ashley McCrary says:

      It states in the recipe that it’s cooked chicken and it does not take 45 minutes to cook chicken as you have stated above. The number you have put down for prep is absolutely false.

  54. Tara says:

    Just made this for dinner. Used a whole bag of Eat Smart fresh cauliflower rice (about 4 cups) and shredded all the meat off a rotisserie chicken. Followed the rest of the recipe exactly and it was delish. Thank you!

    1. Ashley McCrary says:

      SO happy to hear Tara!

  55. Chelsea says:

    OMG, delicious! Like eating a buffalo wing without all the mess. Next time will eat with some celery and really get the hot wing experience. Definitely adding this to my recipe rotation!

    1. Ashley McCrary says:

      YAY! So happy to hear this

  56. Michelle says:

    Ashley you did it again. This Buffalo chicken casserole is sooooo good. Super easy to make, filling and plenty for another meal.

  57. Maddy says:

    Just made this recipe and love it! I prefer chicken thighs, so to make things easy for myself, I cooked the chicken thighs in my instant pot for 15 minutes with a half cup hot sauce and a half cup water. Then shredded the chicken up and added all the ingredients. I love heat so I used hot canned chilies in addition to hot diced canned jalapenos! Also used some fresh pressed garlic.

    1. Ashley McCrary says:

      Yumm! Love it. Thank you

  58. Briana Ramos says:

    This looks amazing. What does the nutritional yeast do in this dish? I don’t have it and was curious to see if there was something I might have in my pantry that could substitute it.

    1. Ashley McCrary says:

      It adds a cheesy taste. It really makes a big difference to the dish!

  59. Iris J. says:

    I made this today for my whole30. It’s delicious! But when I scooped some out of the casserole dish to taste it, it fell apart. Is it supposed to stick together? I thought about putting it back in the oven, but I already cooked it the full time and didn’t want to dry it out. I didn’t use the full amount of cauliflower rice. Could that be why? I would definitely make it again though! Buffalo chicken dip is one of my favorite dishes, and it tastes just like that.

    1. Ashley McCrary says:

      It’s always recommended to use the recipe as written to get the exact result. You can’t change the ingredients or amounts and expect to get the same results. It is an absolutley delicious and amazing dish if you stick to the exact recipe. 🙂

  60. Michelle says:

    Such a delicious, easy recipe!

    1. Ashley McCrary says:

      This is so awesome to hear. Thank you for taking the time to comment and review!

  61. Esther Schiavone says:

    Wow! The Buffalo Chicken Casserole is outstanding! It was so easy to make, put in the fridge and bake it the next day. We had it tonight and my husband loved it too.
    It’s recipes like this that make me want to keep doing Keto. Thank you!

    1. Ashley McCrary says:

      Awww thanks Esther for the kinds words of support. It thrills me to make recipes that become family favorites.

  62. Linda says:

    I’ve made this numerous times with a recipe from, same exact recipe and wording. Since you state that you invented the recipe, I’m wondering if you gave them permission to copy your recipe almost word for word. It is a keeper, that’s for sure!

    1. Ashley McCrary says:

      Thank you so much for letting me know. This is for sure my recipe and sad to hear it is almost copies word for word.

  63. Laurie says:

    Absolutely amazing!!! Anytime I’m craving anything Buffalo Chicken again – I will make this casserole instead. I can’t believe how incredible it tastes – and it’s Whole 30!!!

    1. Ashley McCrary says:

      This made my day. Thank you

  64. Amber says:

    I just wanted you to know how much I appreciate your recipes. This one is one that I love as well as my non keto family. I am making this again tonight because they requested it. Thank you for making healthy food that taste soooo good!

    1. Ashley McCrary says:

      AWWW thank you Amber for such kind words. Making recipes that are helpful to you and my followers is what gives me joy and gets me out of bed each day. Love when one of my creations makes a family favorite rotation. Thank you for connecting with me giving such positive feedback. Happy eating friend!!

  65. Ashley G says:

    Delicious; I love a good casserole and the flavor and texture were great in this one!
