This creamy buffalo chicken cauliflower casserole transforms comfort food into a low-carb delight that still delivers all the satisfying flavors you crave. The combination of spicy buffalo sauce, tender cauliflower, and juicy chicken creates a perfect balance of textures and tastes that will have everyone asking for seconds.
I first created this dish when looking for ways to satisfy my buffalo chicken craving without the heavy carbs. It quickly became our Friday night favorite, with my family now requesting it even more than traditional buffalo wings.
Ingredients
- Large head of cauliflower: the perfect low carb substitute that absorbs all the delicious flavors while adding nutrients
- Cooked shredded chicken breast: adds lean protein and makes this a complete meal. Rotisserie chicken works beautifully here
- Buffalo sauce: the star ingredient that brings that classic spicy tang. I recommend Frank's RedHot for authentic flavor
- Ranch or blue cheese dressing: adds creaminess and balances the heat. Choose blue cheese for more traditional buffalo flavor
- Cheddar cheese: provides sharp flavor and that irresistible cheese pull
- Mozzarella cheese: creates that perfect gooey, melty top layer
- Green onions: adds a fresh bite and color contrast
- Salt and pepper: enhances all the other flavors
- Fresh herbs for garnish: brightens the finished dish with color and freshness
Step-by-Step Instructions
- Preheat the Oven:
- Set your oven to 400°F and take a moment to lightly grease your 9x13 baking dish. This temperature ensures the casserole cooks evenly and gets that perfect bubbly cheese top.
- Prepare the Cauliflower:
- Steam or blanch your cauliflower florets until they are just tender, about 5 to 7 minutes. The key here is not to overcook them as they will continue cooking in the oven. After cooking, drain thoroughly and pat dry with paper towels. Removing excess moisture prevents a watery casserole.
- Mix the Ingredients:
- In a large mixing bowl, combine your shredded chicken, buffalo sauce, and dressing, stirring until the chicken is completely coated. The amount of buffalo sauce can be adjusted depending on your heat preference. Gently fold in the cauliflower florets, ensuring each piece gets coated in the creamy buffalo mixture. Season with salt and pepper to taste.
- Assemble the Casserole:
- Transfer your mixture to the prepared baking dish, spreading it out evenly. Make sure the cauliflower and chicken are distributed uniformly throughout the dish for consistent flavor in every bite. Sprinkle the cheddar and mozzarella cheeses over the top, creating an even layer that will melt into golden perfection.
- Bake:
- Place your casserole in the preheated oven and bake for 20 to 25 minutes. Look for the cheese to become completely melted with light golden spots and bubbling around the edges. This visual cue tells you that the flavors have melded together perfectly.
- Garnish and Serve:
- Pull the casserole from the oven and immediately sprinkle with chopped green onions and herbs if using. The residual heat will slightly wilt them, releasing their aroma. Let the casserole rest for about 5 minutes before serving to allow it to set slightly.

The buffalo sauce is absolutely transformative in this recipe. I discovered its magic when trying to recreate my favorite restaurant appetizer at home. My husband, who typically avoids cauliflower, devoured two servings and declared it better than traditional buffalo chicken dip.
Make Ahead Options
This casserole works wonderfully as a make ahead meal. You can prepare everything up to the baking step, cover tightly with foil, and refrigerate for up to 2 days. When ready to serve, simply add an extra 10 minutes to the baking time. The flavors actually develop nicely when the ingredients have time to mingle in the refrigerator.
Perfect Pairings
While this casserole stands alone as a complete meal, you can round it out with simple sides. A crisp green salad with a light vinaigrette offers a refreshing contrast to the rich casserole. For those not counting carbs, garlic bread makes an excellent accompaniment for soaking up the creamy sauce. For a full buffalo experience, serve with celery sticks and extra blue cheese dressing on the side.
Dietary Adaptations
This recipe is naturally gluten free and keto friendly. For a dairy free version, use dairy free shredded cheese alternatives and a dairy free ranch dressing. To make it vegetarian, replace the chicken with roasted chickpeas or extra firm tofu marinated in buffalo sauce. The versatility of this casserole makes it adaptable to most dietary needs without sacrificing flavor.
