If you’re craving a hearty, flavorful, and slightly spicy casserole without the heaviness of pasta or potatoes, this Creamy Buffalo Chicken Cauliflower Casserole is the perfect dish. It combines tender cauliflower florets, shredded chicken, and bold buffalo sauce with creamy dressing and gooey cheese for a satisfying meal. The dish is packed with protein, rich in flavor, and versatile enough to serve as a family dinner, a game-day snack, or a dish for meal prep.

Cauliflower is a wonderful low-carb substitute for potatoes or pasta in casseroles. Its mild flavor soaks up the buffalo sauce and dressing, creating a creamy, spicy, and cheesy combination that will delight both adults and kids. By layering shredded chicken, cauliflower, and a blend of cheeses, this casserole becomes a comforting, visually appealing dish that can be enjoyed on its own or alongside a fresh salad or steamed vegetables.

In this article, you’ll find a full guide to making this Creamy Buffalo Chicken Cauliflower Casserole, including a step-by-step preparation method, tips for success, serving suggestions, storage advice, and a detailed FAQ section to answer common questions about the recipe.

Why This Casserole Stands Out

This casserole is special because it combines the best of both worlds: the spicy, tangy flavor of buffalo chicken and the creamy, cheesy comfort of a traditional casserole. It’s lower in carbs than most casseroles, thanks to cauliflower replacing traditional starchy ingredients, but still indulgent and filling.

The balance of flavors is key: the heat from buffalo sauce is tempered by ranch or blue cheese dressing, while cheddar and mozzarella add richness and a gooey texture. The addition of green onions adds freshness and a mild bite, and optional parsley or chives provide a vibrant garnish for presentation.

Ingredients You Will Need

To make this flavorful casserole, gather the following ingredients:

• 1 large head of cauliflower, cut into florets
• 2 cups cooked chicken breast, shredded
• 1 cup buffalo sauce (adjust to taste)
• 1/2 cup ranch dressing or blue cheese dressing
• 1 cup shredded cheddar cheese
• 1 cup shredded mozzarella cheese
• 3 green onions, chopped
• Salt and pepper, to taste
• Fresh parsley or chives, chopped, for garnish (optional)

These ingredients come together to create a dish that is spicy, creamy, cheesy, and full of protein while keeping it lower in carbs than traditional casseroles.

Step-by-Step Preparation Method

Follow these steps to make your casserole perfectly:

Step 1: Preheat and Prepare the Cauliflower

Preheat your oven to 375°F (190°C). Wash and cut the cauliflower into bite-sized florets. For a softer texture, steam or boil the florets for 5–7 minutes until slightly tender but not mushy. Drain and pat dry to prevent excess water from making the casserole watery.

Step 2: Prepare the Chicken Mixture

In a large mixing bowl, combine the shredded chicken, buffalo sauce, and ranch or blue cheese dressing. Stir until the chicken is evenly coated. Adjust the amount of buffalo sauce depending on how spicy you want the casserole to be.

Step 3: Assemble the Casserole

In a greased 9×13-inch baking dish, arrange the cauliflower florets evenly. Pour the buffalo chicken mixture over the cauliflower and gently toss to combine. Spread it evenly for a uniform casserole.

Step 4: Add the Cheeses

Sprinkle shredded cheddar and mozzarella evenly over the top of the casserole. This will create a gooey, golden cheese layer once baked. Add the chopped green onions for freshness and mild flavor.

Step 5: Bake the Casserole

Place the dish in the preheated oven and bake for 20–25 minutes, or until the cheese is melted, bubbly, and slightly golden. If you prefer extra browning, you can broil the casserole for an additional 1–2 minutes at the end, keeping a close eye on it to prevent burning.

Step 6: Garnish and Serve

Remove the casserole from the oven and let it sit for 5 minutes before serving. Garnish with freshly chopped parsley or chives, if desired, to add a pop of color and freshness. Serve hot, either as a main dish or a side.

Tips for Perfect Buffalo Chicken Cauliflower Casserole

• Avoid overcooking the cauliflower to maintain texture; it should be tender but not mushy.
• Use freshly shredded chicken for best flavor, or rotisserie chicken for convenience.
• Adjust spice level by adding more or less buffalo sauce.
• Drain cauliflower well to prevent the casserole from becoming watery.
• Cheese blend: Feel free to experiment with pepper jack or Monterey Jack for extra flavor.
• Rest before serving to allow the casserole to set slightly for easier serving.

Serving Suggestions

This casserole is versatile and can be enjoyed in several ways:

• Serve with a side of steamed vegetables or a green salad for a complete meal.
• Pair with ranch or blue cheese dipping sauce for extra flavor.
• Serve alongside roasted potatoes or cauliflower rice for a hearty dinner.
• Offer as a game-day appetizer or party dish for friends and family.
• For meal prep, divide into portions for grab-and-go lunches or dinners.

Storage Instructions

Proper storage ensures the casserole remains flavorful and retains its texture:

Refrigerator: Cover the cooled casserole with foil or an airtight lid. Store for up to 4 days. Reheat in the oven at 350°F (175°C) for 10–15 minutes or in the microwave until heated through.

Freezer: Portion the casserole into freezer-safe containers for up to 2 months. Thaw overnight in the refrigerator before reheating in the oven or microwave.

Creative Variations

• Spicy Kick: Add diced jalapeños or a dash of cayenne to the buffalo chicken mixture.
• Cheese Variation: Mix in pepper jack or smoked cheddar for extra depth.
• Ranch vs. Blue Cheese: Swap ranch for blue cheese dressing for a richer, tangier flavor.
• Low-Sodium Option: Use low-sodium buffalo sauce and cheeses to reduce salt content.
• Extra Veggies: Add steamed broccoli or bell peppers for additional nutrients and color.

These variations allow you to customize the casserole for flavor, spice, and nutrition.
