Cheesy buffalo chicken dip is a popular appetizer everyone seems to love, so why not turn it into a keto-friendly buffalo chicken casserole we can all enjoy for dinner? This recipe is made with a mixture of shredded chicken, riced cauliflower, and a mixture of cheeses, making it high in fat, full of fiber, and most importantly, low in carbs!

The good thing about this buffalo chicken keto casserole is that you can control the heat! If someone doesn’t like spicy food, you can dial it down by choosing the right sauce and not using too much of it! A win-win for all! Read more about that below. The best part of this casserole is the sauce. I added ranch dressing because it goes so well with buffalo sauce, but you can add in blue cheese if you prefer!

Your shredded chicken

Shredded chicken is a staple in buffalo chicken casseroles and is very easy to make. Plus, it is super cost-efficient! I like to add boneless chicken thighs or breasts to my crock pot and boil it for a few hours. You can also cook it in a saucepan. Check out exactly how I make shredded chicken using my slow cooker. You can make a large batch at once, shred it all up and portion it out for future keto casseroles!

If you DON’T have much time on your hands, pick up a rotisserie chicken from the store and remove the legs, thighs, and breasts. Take out the bones and shred using two forks. You can also use a knife to chop up the chicken if it’s too tough to shred properly.

How to make your buffalo sauce more/less spicy

I have a go-to brand of buffalo sauce I like to use, so choose whichever sauce you like BEST. Some hot sauces may still be a bit too spicy for you, so to dial down the heat, simply use less buffalo sauce. I recommend replacing the amount of sauce you removed with more melted butter.

If you LOVE spicy foods, you can always add more buffalo sauce. (about 1/4 to 1/2 cup more). With that said, too much sauce may make your casserole runny. So another option is to use a spicier sauce from the get-go.

Yum! This Keto Buffalo Chicken Casserole was a nice change of pace. My hubby and big kids loved it. Since they enjoy hot foods, it was right up their alley.

Why use riced cauliflower?

Riced cauliflower in this recipe adds nutrients, fiber and is what separates buffalo chicken DIP from buffalo chicken CASSEROLE. It turns it into a hearty meal, so I don’t recommend leaving it out. Without it, your casserole would be flat, dense, and not very “casserole-like.”

Tips for cooking and ricing cauliflower:

Cauliflower can be purchased frozen or fresh.

FRESHLY riced cauliflower

If you purchase a whole head of cauliflower, all you need to do is cut it down into small florets. Then you have the option to boil it or steam it.

If you boil your florets, whether on the stove or in your microwave, it is important to make sure you let your cauliflower FULLY COOL before adding it to the buffalo sauce. You don’t want a watery sauce.

The best way to cool your cauliflower is to lay the boiled cauliflower out on a sheet pan. Then allow the steam to evaporate fully. Once it’s cooled and the steam is gone, you can continue with the recipe.

FROZEN riced cauliflower

I love how almost every grocery store these days has pre-riced cauliflower pre-packaged in bags. You can find them in the frozen foods aisle where the veggies are. If your store has it, get the steam-able bags that allow you to steam cauliflower straight in the microwave, in the bag, in no time without making a mess!

    Oh. My. Stars. This was heavenly. Usually when I make a keto casserole, I’m dishing servings to my non-keto family members but I’m perfectly fine keeping all 9 servings of this to myself!

  2. This looks amazing. I forgot the cream cheese at the grocery store… Can I leave it out or are there good substitutes?? Thanks so much!

    1. We always have a selection of wing sauces. My hubby and 2 older kids love it. For this dish, a very traditional buffalo sauce is ideal. Sweet Baby Ray’s is a great option here because it is very traditional in flavor. I will say I have used whatever is in the fridge before too. So, I would suggest a solid traditional sauce. Nothing fancy.

  3. I despise cauliflower so I chopped up a zucchini and sautéed with the vegetables and it was a great substitute.

    1. Great thinking Katie! Glad you enjoyed it, and really glad you shared that here. Maybe someone else like you would prefer zucchini over cauliflower. Thanks!

    1. Hey Jay, thanks for the question. There is a ton of data online about the benefits of a keto lifestyle. It may or may not be for you. This is where it comes down to each person’s research to decide what works best for them. Good luck with whatever you try!
