Ingredients You’ll Need

For the Casserole:

1 medium head cauliflower, cut into florets (about 4 cups)
2 cups cooked shredded chicken (rotisserie works great!)
½ cup cream cheese, softened
½ cup sour cream
½ cup buffalo sauce (adjust to taste)
½ tsp garlic powder
½ tsp onion powder
½ tsp smoked paprika
½ tsp salt
¼ tsp black pepper

For the Topping:

1 cup shredded cheddar cheese
½ cup shredded mozzarella cheese
¼ cup chopped green onions
¼ cup crispy turkey bacon bits (optional, but highly recommended!)

How to Make Creamy Buffalo Chicken Cauliflower Casserole

Step 1: Prep and Cook the Cauliflower

To get that perfect tender but not mushy cauliflower, follow these steps:

Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
Steam or boil the cauliflower for about 5 minutes until it’s slightly tender. (It should be fork-tender but still have some bite.)
Drain it well and set it aside.

🔎 Tip: Make sure your cauliflower is well-drained! Any extra moisture can make the casserole watery. For best results, pat it dry with a paper towel before mixing.

2 Step: Make the Creamy Buffalo Sauce

This sauce is the secret to making the casserole ultra-creamy and flavorful.

In a large bowl, mix together:
- Cream cheese (softened so it mixes smoothly)
- Sour cream
- Buffalo sauce (adjust the amount based on your spice preference)
- Garlic powder, onion powder, smoked paprika, salt, and black pepper.
Stir until everything is fully combined and smooth.

💡 Pro Tip: If you prefer a milder casserole, reduce the buffalo sauce to ⅓ cup and add ¼ cup heavy cream for extra creaminess.

Step 3: Combine the Ingredients

Add the shredded chicken and cooked cauliflower to the buffalo mixture.
Stir until all the ingredients are well-coated in the creamy buffalo sauce.

Next Steps

The base is ready! Now, let’s assemble the casserole, top it with cheese, and bake it to golden, bubbly perfection.

Now that our buffalo chicken mixture is ready, it’s time to assemble the casserole and make it cheesy, bubbly, and irresistible. This is where the magic happens!

Step 4: Assemble the Casserole

Transfer the buffalo chicken and cauliflower mixture to your greased 9×13-inch baking dish. Spread it evenly to ensure that every bite is packed with flavor.
Sprinkle the shredded cheddar and mozzarella cheese evenly over the top.

🧀 Why use two cheeses?

Cheddar cheese adds a sharp, bold flavor that pairs beautifully with buffalo sauce.
Mozzarella cheese melts into a gooey, stretchy topping for that ultimate cheesy pull!

Step 5: Bake to Perfection

Place the casserole in the preheated oven (375°F / 190°C).
Bake for 20-25 minutes, or until the cheese is melted, bubbly, and slightly golden on top.

🔥 Want an extra crispy topping? Broil the casserole for 2-3 minutes at the end of baking for a lightly golden, toasty cheese crust.

Step 6: Garnish and Serve

Now, let’s add some fresh flavors and a bit of crunch:

Sprinkle chopped green onions over the top for a fresh, zesty kick.
Add crispy turkey bacon bits (optional, but SO good!) for extra crunch.

Serving Suggestions

This casserole is hearty enough to be a full meal on its own, but if you want to make it a complete dinner, try these pairing ideas:

Serve it with celery sticks or carrot sticks for a cool, fresh contrast.
Pair it with a side salad, like a crisp ranch coleslaw or a simple garden salad.
Drizzle with ranch dressing or blue cheese dressing for extra flavor!
