This creamy Buffalo chicken cauliflower casserole is my go-to when I want big flavor with a light touch. It brings together the spicy tang of Buffalo sauce with cool ranch, plenty of melty cheese, and bites of roasted cauliflower for a family-friendly dish you can feel good about digging into. Whether for a busy weeknight or a potluck, it always wins over even the pickiest eaters.
I first threw this together for a game day party and it disappeared before the second quarter ended. Now it is a staple whenever we want takeout flavor at home without the heaviness.
Ingredients
- Cauliflower florets: fresh is best for texture and flavor look for a firm head without brown spots
- Cooked chicken breast: shredded or diced use rotisserie for convenience or poach extra chicken while making the recipe
- Buffalo sauce: choose your preferred heat and quality thicker sauces cling better to the ingredients
- Ranch or blue cheese dressing: creamy dressings balance the heat choose a quality refrigerated brand if you can
- Shredded cheddar cheese: sharp varieties cut through the sauces and give stronger cheese pulls
- Shredded mozzarella cheese: for that classic melt and stretch always grate fresh if possible
- Green onions: add fresh zip and crunch pick ones with bright greens and no wilting
- Salt and pepper: to taste go with sea salt and cracked black pepper to boost everything
- Fresh parsley or chives: optional but they brighten up the casserole and add color
Step-by-Step Instructions
- Preheat the Oven:
- Set your oven to four hundred degrees Fahrenheit which is key for getting that golden cheese on top while keeping everything creamy underneath. Lightly grease a large casserole dish to prevent sticking.
- Prepare the Cauliflower:
- Steam or blanch florets until just fork tender which usually takes about five to seven minutes. You want them tender but not mushy. Drain thoroughly and pat each piece dry with towels since too much water can make the casserole runny.
- Mix the Ingredients:
- In a spacious bowl whisk together chicken buffalo sauce and your chosen dressing until well combined. Add the dried cauliflower and gently toss to coat every floret and shred. This ensures every bite is both spicy and creamy. Season with salt and pepper to your own taste.
- Assemble the Casserole:
- Put the cauliflower chicken mixture into your greased baking dish and spread it out evenly. Top with a generous sprinkle of cheddar and mozzarella for max cheesy coverage.
- Bake:
- Place the casserole on the middle oven rack for about twenty to twenty five minutes. Look for bubbling cheese and golden edges to signal it is ready. Every oven varies so keep an eye out at the twenty minute mark.
- Garnish and Serve:
- Let the casserole rest for a few minutes so it sets. Add a handful of sliced green onions and optional fresh herbs for color and brightness. Dish it up while still hot.

I always look forward to the blend of sharp cheddar with cool creamy ranch throughout the dish. My kids like to customize their servings with extra sauce or fresh herbs and often try to sneak the crispy cheese from the corners.
Storage Tips
This casserole keeps well in the fridge for up to three days stored tightly covered. I reheat leftovers in the oven to bring back the best texture but a quick microwave zap works too if you are in a hurry. If you have a lot leftover portion it into smaller containers for lunches.
Ingredient Substitutions
No ranch or blue cheese dressing Try plain Greek yogurt or sour cream with a bit of garlic powder and dried herbs for a lighter creamy sauce. If you need it dairy free choose your favorite plant based cheeses and dressings. Rotisserie chicken is my secret for ultra fast prep but any leftover roast chicken or even turkey works in a pinch.
Serving Suggestions
We love this casserole as a main with a crisp green salad on the side for balance. You can also spoon it into lettuce cups or stuff it into low carb wraps for a fun meal prep lunch. Sprinkle extra hot sauce for those who can handle it or top with a dash of celery salt.
Cultural and Historical Context
Buffalo flavor has roots in upstate New York where spicy buttery hot sauce first coated crispy chicken wings. Over the years I have seen Buffalo sauce show up in pizza bowls and even mac and cheese. This casserole is my riff on all those comforting flavors just made lighter and a bit healthier.
