Keto Buffalo Chicken Casserole

This KETO BUFFALO CHICKEN CASSEROLE starts off with a cheesy cauliflower base and then gets buffalo chicken stirred right in. We bake this until it’s hot and bubbly and then drizzle with a bit more buffalo sauce and ranch dressing.

A few of my favorite restaurants have a buffalo chicken mac and cheese on the menu and I have to admit…I want it every time.

I decided to make my own version and I knew just the place to start!

My cauliflower mac and cheese is a favorite here with readers and in my home with family, so I knew it’d be the perfect base for this buffalo chicken casserole.

All the cheesy goodness of mac and cheese, spicy chicken, and a hefty drizzle of keto ranch dressing.

Yes, you can totally use blue cheese, if that’s your thing. I’ll always be TEAM RANCH myself. 😉

How to:

Start with fresh cauliflower. Frozen riced cauliflower may work, but I always recommend using fresh because the flavor and texture are just a million times better.

Chop the cauliflower into small, macaroni-sized pieces.

Boil the cauliflower, drain, and then add in your buffalo sauce, cream, cheese, and seasonings. Stir that up until it’s all melty and irresistible.

Toss some cooked, chopped or shredded chicken with buffalo sauce and stir that right into the cauliflower.

We like to use a rotisserie chicken to keep this easy.

Spread this mixture into a casserole dish and bake until it’s hot and bubbly, about 15 minutes.

We top this off with an extra drizzle of buffalo sauce, ranch or blue cheese dressing, and a sprinkling of green onions.

FAQ’s:

Is this keto buffalo chicken casserole spicy?

As written, the recipe definitely has a kick, but it’s still on the mild side.
You can reduce the amount of buffalo sauce used in the cheese sauce or on the chicken to make this more mild.
To make this dish more spicy, use Frank’s Red Hot Sauce instead of buffalo wing sauce or add in a little dried cayenne pepper.

Can I use frozen cauliflower rice instead of fresh?

Probably, but I haven’t tested it. Fresh produce will always taste better and have a better texture than frozen, so I recommend using fresh cauliflower.
Most grocery stores carry already chopped cauliflower in the produce section.

Where are the carbs coming from in this recipe?

Cauliflower, contrary to popular belief, does contain carbs. It also has a lot of fiber to balance it out. The carbs in this recipe come mostly from the cauliflower, but also from the cream and cheese.
