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.

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!

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. 
Prep Time: 5 minutes
Servings: 4 -5


  • 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.


  • 1/2 tsp salt
  • 1 tsp paprika
  • 1/2 tsp pepper
  • 3/4 tsp garlic powder
  • 2 1/2 tbsp nutritional yeast


  • Preheat oven to 350F.
  • Coat a 9X9 or a 9X13 baking dish with olive oil.
  • 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. 
  • Mix all the ingredients together until completely combined. 
  • Transfer the mixture to the baking dish and add to the oven. 
  • Bake for 35-40 minutes or until the top is crispy and bubbling. 
  • Drizzle with ranch, top with fresh chopped green onions and add a little more Franks Hot Sauce to the top.
  • 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.

    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. 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.

    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!

  3. 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!

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

    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.

    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.

    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. 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. 🙂
