Buffalo Chicken Cauliflower Casserole is the kind of weeknight dinner that brings bold flavor without the fuss. Tender shredded chicken, roasted cauliflower, and creamy buffalo sauce bake together into a bubbling, cheesy casserole that hits every craving. I made this on a cold Tuesday night when I needed something hearty but not heavy, and it immediately earned a permanent spot in my dinner rotation.
What makes this dish special is how it balances spice with creaminess. The buffalo sauce delivers that tangy kick, while the cream cheese and cheddar mellow everything into something deeply satisfying. It works for game day, meal prep, or a cozy family dinner. And the best part? It comes together in under an hour with simple, everyday ingredients.

Ingredients for Buffalo Chicken Cauliflower Casserole
Every time I make this casserole, I keep the ingredient list tight and straightforward. No fancy store runs, no hard-to-find items. Just real food that works together beautifully.
- 4 boneless, skinless chicken breasts (about 1.5 lbs)
- 4 cups cauliflower florets (cut into even pieces for consistent roasting) – I recommend cutting them slightly smaller so they roast faster and absorb more sauce
- 1 cup buffalo sauce – My preference is Frank’s RedHot for its balanced heat and tang; it gives the most authentic flavor
- 8 oz cream cheese (softened at room temperature) – In my experience, softened cream cheese blends far more smoothly into the chicken mixture
- 1 cup shredded sharp cheddar cheese, divided
- 3 green onions, sliced
- 2 tablespoons olive oil
- Salt and pepper, to taste – I usually season generously at each stage for the best depth of flavor
Step-by-Step Instructions
I recommend reading through all the steps before you start. This casserole moves quickly once the oven is hot, and staying one step ahead makes everything run smoothly.
Step 1: Preheat your oven to 400 degrees F (200 degrees C). Lightly coat a 9×13 baking dish with nonstick cooking spray.
Step 2: Toss the cauliflower florets with olive oil, salt, and pepper until evenly coated. Spread them in a single layer in the baking dish. Roast for 15 minutes until the edges are golden and the florets are just tender. Avoid overcrowding or they will steam instead of roast.
Step 3: While the cauliflower roasts, season the chicken breasts with salt and pepper on both sides. Cook in a skillet over medium heat for 6 to 8 minutes per side until fully cooked through and no longer pink inside. Transfer to a cutting board and shred using two forks.
Step 4: In a large mixing bowl, combine the shredded chicken, buffalo sauce, and softened cream cheese. Stir until fully blended and creamy. Fold in half of the shredded cheddar. The mixture should look thick and evenly coated.
Step 5: Add the roasted cauliflower to the bowl and fold everything together gently so the florets stay intact. Transfer the mixture back into the baking dish and spread it evenly.
Step 6: Scatter the remaining cheddar cheese and sliced green onions over the top. Bake for 15 to 20 minutes until bubbly and golden on top. Serve hot with extra buffalo sauce drizzled on top if you like more heat.
What to Serve with Buffalo Chicken Cauliflower Casserole
This casserole is bold and saucy, so the best sides add contrast through coolness, crunch, or freshness.
Celery and Carrot Sticks: A classic buffalo pairing for good reason. The cool crunch cuts right through the richness of the cheese and sauce, and it adds a fresh texture without any extra cooking.
Simple Green Salad: A lightly dressed salad with romaine or arugula brings a refreshing lift to the plate. The mild greens balance the spice without competing with the main dish’s strong flavors.
Cauliflower Rice: If you want to keep things low-carb, cauliflower rice is a natural partner. It soaks up the buffalo sauce beautifully and keeps the whole meal light and clean.
Warm Crusty Bread: For those who want something heartier, a slice of crusty sourdough or a dinner roll is perfect for scooping up every bit of the saucy filling from the dish.
Blue Cheese or Ranch Dip: A small bowl of blue cheese or ranch dressing on the side adds a cool, creamy element that pairs perfectly with the spicy buffalo flavor profile.
Storage and Serving Tips
Store any leftovers in an airtight container in the refrigerator for up to 4 days. This casserole actually tastes even better the next day once the flavors have had time to settle and deepen.
To reheat, place it in an oven-safe dish at 350 degrees F for about 10 to 15 minutes until warmed through and bubbly again. For a quick lunch, the microwave works fine. Just heat in 60-second intervals, stirring between each, to avoid drying it out.
Pro tip: this dish works great for meal prep. Portion it into individual containers right after baking and you have easy, high-protein lunches ready for the week. I recommend adding a fresh drizzle of buffalo sauce after reheating to bring the flavors back to life.
