Creamy Buffalo Chicken Cauliflower Casserole

Creamy Buffalo Chicken Cauliflower Casserole is the answer when you want serious comfort without all the carbs. Tender bits of cauliflower soak up spicy buffalo sauce and get tossed with juicy shredded chicken and loads of melty cheese. With a touch of ranch dressing and a bubbly, golden topping, it is totally satisfying but feels lighter on your plate. This casserole has come to my rescue on busy weeknights and always earns requests for seconds.

My family loves the punch of buffalo flavor here and I usually make it for game days or chilly evenings when everyone wants something cozy. The leftovers even heat up beautifully for lunch the next day.

Ingredients

• Large head of cauliflower: fresh crisp heads work best and provide the tender bite
• Cooked chicken breast: use rotisserie or home-cooked for the juiciest results
• Buffalo sauce: go for your favorite brand or homemade and adjust heat level to your taste
• Ranch or blue cheese dressing: pick whichever creamy tang you prefer for the sauce
• Shredded cheddar cheese: sharp cheddar gives the best flavor punch
• Shredded mozzarella cheese: brings meltiness and helps blend all the ingredients
• Green onions: add bold color and onion zip to the finished dish
• Salt and pepper: balance all the bold flavors
• Fresh parsley or chives: bright green finish and fresh flavor pop

For the best result pat your cauliflower dry after steaming to avoid a watery casserole and always go for block cheese you shred yourself for extra creamy melt.

Step-by-Step Instructions

Preheat the Oven:

Set your oven to 400 degrees Fahrenheit and grease a large baking dish to prevent sticking

Prepare the Cauliflower:

Steam or blanch cauliflower florets for about 5 to 7 minutes until they are tender but not mushy then drain and pat them very dry with paper towels

Mix the Ingredients:

Combine shredded chicken with buffalo sauce and ranch or blue cheese dressing stirring to coat well then fold in the cauliflower making sure every bite gets sauced

Assemble the Casserole:

Spread the cauliflower and chicken mixture evenly in your baking dish then top with cheddar and mozzarella making sure there is plenty of coverage so it all melts into a bubbly topping

Bake:

Put the dish in the preheated oven and bake for 20 to 25 minutes until the cheese is melted and starting to brown and everything is heated through

Garnish and Serve:

Scatter chopped green onions and fresh parsley or chives over the top for a fresh look and flavor then serve steaming hot right from the oven

I am extra picky about my buffalo sauce and after plenty of trial and error I now seek out the one with the most tang and a hint of butteriness. One memorable time my youngest forgot it was a spicy dish and took a gigantic bite just to grin and ask for more.

Storage Tips

Let the casserole cool to room temperature before storing

• Use airtight containers and keep refrigerated for up to three days
• To reheat use the oven at a low temperature for the best texture but the microwave is handy for quick meals
• If you like freezing your casseroles assemble everything but wait to bake until ready to serve

Ingredient Substitutions

Try swapping cooked turkey or rotisserie chicken thighs for a richer flavor

• Dairy free cheese melts can be used for those avoiding dairy
• Greek yogurt with a splash of lemon juice works instead of ranch or blue cheese
• If you love crunch you can add some toasted walnuts or sunflower seeds to your topping

Serving Suggestions

This is delicious on its own but I also serve it over a bed of crisp lettuce or with celery sticks for extra crunch

• A side of cucumber salad or roasted broccoli makes a bright contrast
• You can even tuck leftovers into lettuce wraps for a spicy lunch
