Ingredients

For the Creamy Buffalo Chicken Cauliflower Bake, you’ll need:

• 1 large head cauliflower (about 2 lbs/900g), cut into florets
• 2 tablespoons (30ml) olive oil
• 2 lbs (900g) boneless, skinless chicken breasts, cubed
• 1 teaspoon (5g) garlic powder
• 1 teaspoon (5g) onion powder
• Salt and pepper to taste
• 8 oz (225g) cream cheese, softened
• 1/2 cup (120ml) buffalo sauce (Frank’s RedHot recommended)
• 1/4 cup (60ml) ranch dressing
• 3/4 cup (85g) mozzarella cheese, shredded
• 3/4 cup (85g) cheddar cheese, shredded
• 2 green onions, thinly sliced
• Optional garnish: chopped fresh parsley, blue cheese crumbles

The buffalo sauce provides the signature tangy heat, while the cream cheese and ranch dressing create that luxurious creaminess that makes this Buffalo Chicken Cauliflower Casserole so irresistible. For best results, use fresh cauliflower rather than frozen to ensure the perfect texture.

Pro Tips

Pre-roast the cauliflower: The secret to avoiding a watery casserole is to pre-roast your cauliflower florets before adding them to the casserole. Spread them on a baking sheet, drizzle with olive oil, season with salt and pepper, and roast at 425°F (220°C) for 20 minutes until the edges begin to brown. This step removes excess moisture and concentrates the cauliflower’s flavor, creating a much better foundation for your Creamy Buffalo Chicken Cauliflower Casserole.

Temperature control for cream sauce: When making the buffalo cream sauce, ensure your cream cheese is fully softened before mixing. If it’s too cold, it won’t blend smoothly. For an ultra-creamy result, combine the cream cheese, buffalo sauce, and ranch dressing in a saucepan over low heat, stirring constantly until perfectly smooth before adding to the other ingredients.

Rest before serving: Allow your Buffalo Cauliflower Chicken Casserole to rest for 10-15 minutes after baking. This patience pays off enormously – the rest time allows the sauce to thicken and the flavors to settle, making each bite more cohesive and flavorful. Plus, it prevents that disappointing runny sauce that can happen when cutting into a casserole too quickly.

Instructions

Step 1: Prepare the Cauliflower

Preheat your oven to 425°F (220°C). Cut the cauliflower into bite-sized florets and place them on a large baking sheet. Drizzle with 1 tablespoon olive oil, season with salt and pepper, and toss to coat evenly. Spread the florets in a single layer and roast for 20 minutes until they begin to brown at the edges. This pre-roasting step is crucial for a non-watery Creamy Buffalo Chicken Cauliflower Casserole.

Step 2: Cook the Chicken

While the cauliflower roasts, heat the remaining tablespoon of olive oil in a large skillet over medium heat. Add the chicken cubes and season with garlic powder, onion powder, salt, and pepper. Sauté until the chicken is cooked through and slightly browned, about 7-8 minutes. The chicken should reach 165°F (74°C) internally. Set aside.

Step 3: Create the Buffalo Cream Sauce

In a medium bowl, combine the softened cream cheese, buffalo sauce, and ranch dressing. Mix until completely smooth. If you’re having trouble getting it smooth, warm the mixture gently in a saucepan over low heat while stirring constantly. This velvety sauce is what gives your Buffalo Chicken Cauliflower Casserole its signature creamy texture.

Step 4: Assemble the Casserole

Reduce oven temperature to 350°F (175°C). In a large mixing bowl, gently combine the roasted cauliflower and cooked chicken. Pour the buffalo cream sauce over the mixture and stir carefully to coat everything evenly. Transfer to a 9×13 inch (23×33 cm) baking dish.

Step 5: Add Cheese and Bake

Sprinkle the combined mozzarella and cheddar cheeses evenly over the top of the casserole. Bake uncovered for 20-25 minutes until the cheese is melted, bubbly, and beginning to brown in spots. For an extra golden top, broil for the final 2 minutes, watching carefully to prevent burning.

Step 6: Garnish and Serve

Remove your Creamy Buffalo Chicken Cauliflower Casserole from the oven and let it rest for 10-15 minutes. This resting time is essential for the sauce to set properly. Sprinkle with sliced green onions and optional blue cheese crumbles or parsley before serving. Each bite should deliver that perfect balance of spicy, creamy, and savory flavors.

Variations

Extra Spicy Buffalo Cauliflower Chicken Bake: For heat lovers, add 1-2 tablespoons of minced jalapeños to the mixture and use a spicier buffalo sauce. You can also add a teaspoon of cayenne pepper to the chicken seasoning for an extra kick that elevates the traditional Creamy Buffalo Chicken Cauliflower Casserole.

Mediterranean Version: Transform this dish by replacing the buffalo sauce with 1/4 cup of sun-dried tomato pesto. Use feta instead of cheddar cheese, add a handful of chopped olives, and garnish with fresh basil instead of green onions. The tangy feta provides a similar flavor contrast to the blue cheese in the original recipe.

Vegetarian Buffalo Cauliflower Casserole: Skip the chicken entirely and double the cauliflower, or substitute with 2 cups of chickpeas or white beans for protein. The creamy buffalo sauce works wonderfully with just vegetables, creating a satisfying vegetarian main dish that still captures the essence of the original Buffalo Chicken Cauliflower Casserole.

Storage and Serving

This Creamy Buffalo Chicken Cauliflower Casserole stores beautifully in the refrigerator for up to 4 days in an airtight container. The flavors actually improve overnight as they continue to meld. Reheat individual portions in the microwave for 2-3 minutes or larger amounts in a 350°F (175°C) oven for 15-20 minutes until heated through.

For freezing, cool the casserole completely, then cover tightly with plastic wrap and aluminum foil. It will keep for up to 3 months. Thaw overnight in the refrigerator before reheating.

Serve this casserole alongside a simple green salad with a light vinaigrette to balance the richness. For a more substantial meal, pair it with garlic bread for those who aren’t counting carbs. If you’re hosting a game day gathering, offer small portions as a hearty appetizer alongside celery and carrot sticks with extra ranch dressing for dipping – a nod to traditional buffalo wings.

FAQs

Can I use frozen cauliflower for this recipe?
While fresh is preferred, you can use frozen cauliflower in a pinch. Thaw it completely and pat it very dry before roasting. You’ll need to roast it longer to remove the extra moisture, about 25-30 minutes.

How can I make this Buffalo Chicken Cauliflower Casserole milder?
To reduce the heat, use a mild buffalo sauce and increase the amount of ranch dressing to 1/3 cup. You can also mix in 2 tablespoons of honey to balance the spice with sweetness.

Can I prepare this casserole ahead of time?
Absolutely! You can assemble the entire casserole up to 24 hours ahead and refrigerate it covered. When ready to bake, add an additional 10-15 minutes to the baking time since you’ll be starting with a cold dish.

What can I substitute for ranch dressing?
Blue cheese dressing makes an excellent substitute and pairs wonderfully with buffalo flavors. For a healthier option, try plain Greek yogurt mixed with a ranch seasoning packet.

Is this casserole keto-friendly?
Yes! With cauliflower as the base and no added starches, this Creamy Buffalo Chicken Cauliflower Casserole fits perfectly into a ketogenic diet. Just double-check your buffalo sauce to ensure it doesn’t contain added sugars.

Conclusion

This Creamy Buffalo Chicken Cauliflower Casserole is comfort food at its finest — a perfect harmony of spicy, tangy buffalo heat tamed by creamy cheese, with hearty chicken and tender cauliflower creating a satisfying meal that doesn’t weigh you down.
