My daughter was always scared to try anything Buffalo spiced. But then I made this awesome Buffalo chicken casserole recipe and it’s now one of her favorite dinners! She’s in fact a huge fan of Buffalo chicken dishes, as long as they’re not too spicy.

Luckily, when you make your own you can put in your own preferred amount of fiery Buffalo sauce spice.

What is Buffalo chicken?

Buffalo chicken is a chicken dish that’s typically hot and spicy. The chicken is coated in a hot sauce, a spicy Buffalo sauce, which is made from hot sauce and butter. Buffalo refers to the city where it was created, which is why it’s normally capitalized.

However, contrary to popular belief, Buffalo sauce is not just for hot wings!

🌶 How to use Buffalo sauce

You’ll most often hear about using Buffalo sauce for Buffalo wings, Buffalo chicken dip (I love Buffalo chicken dip and have a keto Buffalo chicken dip recipe coming soon!), Buffalo chicken tenders, Buffalo chicken meatballs, etc.

You can check out my keto Buffalo sauce recipe if you’d like to make your own. It’s a wonderful recipe, faster than you’d think, made with a few simple ingredients including Frank’s hot sauce (or your preferred brand of hot sauce) and butter.

Easy keto recipes and dinners are always good in my book!

I don’t know about you, but when I try a recipe, it rarely comes out exactly as listed in the nutritional facts of the recipe. It’s especially important to determine your own if you’re keeping close track and want to be accurate on a keto diet.

🍽 Equipment needed to make this low carb chicken casserole

The first and most obvious kitchen item you’ll need to make this spicy Buffalo chicken recipe is the casserole dish! I use a 9×13-inch casserole dish and it’s a perfect size.

You’ll also need a good knife to cut up the chicken into bite-sized pieces. Whether you’ve cooked chicken breasts or are using both the white and dark meat of a rotisserie chicken, a cutting board will also come in handy.

• large and medium-sized bowls
• a 9X13-inch baking dish
• a spatula
• whisk
• measuring cups and spoons
• knife
• cutting board

🥘 Ingredients in low carb Buffalo chicken casserole

The ingredients you’ll need to make keto Buffalo chicken casserole are:

• 8 oz cream cheese – Leave the cream cheese out to room temperature.
• 2 large eggs
• 1/2 cup keto blue cheese dressing (homemade or sugar free store bought) – You can also substitute a sugar free ranch dressing, sour cream, or mayonnaise with keto-approved ranch seasoning or garlic powder.
• 1/2 cup keto Buffalo sauce (homemade or sugar free store bought) – This is a super easy recipe not just for Buffalo wings made with butter and Frank’s red hot sauce (or whatever hot sauce you prefer).
• 1/2 cup thinly sliced celery sticks
• 1/3 cup sliced green onion (plus more to garnish (optional)
• 1/2 tsp salt
• 2 cups shredded cheddar cheese
• 4 cups chopped cooked chicken (or shredded chicken). I prefer to cook chicken breasts and use cubed chicken, but you can also use rotisserie chicken in a hurry.
• 4 cups organic riced cauliflower – I often use the Kirkland frozen cauliflower rice because it’s easy. However, you can also rice cauliflower by pulsing cauliflower florets in a food processor.
• 1/4 cup blue cheese crumbles
• 1/4-1 tsp cayenne pepper to taste (to add heat: optional)

The list of ingredients itself is making me hungry! Just looking at all of these keto Buffalo chicken casserole ingredients is making my mouth water.

So we’d better get to it!

🔪 Instructions: how to make spicy Buffalo chicken casserole

Be sure to follow the recipe instructions carefully so you end up with a delicious keto Buffalo chicken casserole everyone will love.

First of all, preheat the oven to 375 degrees F (190 degrees C). Then grease a 9×13 inch baking dish with butter or cooking spray. I like to use avocado or olive oil.

Mix the cream cheese

With a stand or hand mixer, blend up the cream cheese until there are no lumps.

Next, to the cream cheese, add in the eggs, blue cheese dressing, buffalo sauce, and salt. Mix it all up well. If you want it to be extra spicy, add 1/4-1/2 teaspoon of cayenne pepper now. The blue cheese dressing (or ranch dressing) really makes the keto Buffalo chicken casserole extra creamy and will also help it to not dry out as much while baking.

Keto blue cheese dressing: top tips!

My preferred keto blue cheese dressing is to make your own. However, if you buy one, be sure to read the labels for any added sugar or ingredients. You can also substitute a keto-friendly ranch dressing or even mayonnaise in a pinch.

Finish the casserole

After that, mix in the celery, green onions, and 1 cup of shredded cheddar cheese.

Now add in the bite-sized chopped (or shredded) chicken and cauliflower rice and stir well. If you’re using frozen riced cauliflower, thaw and drain it before adding it to the chicken mixture.

Then use a spatula to transfer the mixture to the greased baking dish. Finally, sprinkle the remaining 1 cup of cheddar cheese evenly over the top, and then the blue cheese crumbles.

⏲ Bake time

Bake the keto Buffalo casserole for about 40-45 minutes until the cheese begins to brown and the casserole is bubbling.

Personally, I like to let it cool for about 10 minutes before cutting into it.

Add some more color and flavor if you wish and garnish with sliced green onions and more blue cheese. You can also get creative and add more chopped celery, cheddar cheese, even ground pork rinds, or whatever you prefer.

Now dig in and enjoy!

🥣 How to store this easy chicken low carb casserole
