Buffalo Chicken Cauliflower Casserole is a tasty twist on classic comfort food, blending spicy buffalo chicken with tender, roasted cauliflower. This dish has a wonderful mix of creamy cheese and zesty buffalo sauce that brings a little kick without being overwhelming. It’s a great way to enjoy all the flavors of buffalo chicken wings but in a warm, cozy casserole form.
I love making this casserole when I want something filling but not too heavy or greasy. The cauliflower adds a nice texture and keeps things feeling a bit lighter than your typical buffalo chicken dishes. Plus, it’s super easy to throw together on a busy weeknight. I often add a little extra cheese on top to get that golden, melty finish that everyone always goes crazy for.
My favorite way to serve this is with a side of crunchy celery sticks and a dollop of ranch or blue cheese dressing to cool off the spice. It’s a crowd-pleaser at any gathering, and I find that even folks who usually shy away from cauliflower end up asking for seconds. This casserole has quickly become one of my go-to recipes when I want comfort food with a bit of a healthy twist.
Key Ingredients & Substitutions
Cauliflower: This is the main vegetable that keeps the dish light and healthy. I like using fresh cauliflower florets for better texture. If you’re short on time, frozen cauliflower works too—just thaw and drain well.
Chicken: Cooked chicken breast adds protein and balances the heat. Rotisserie chicken is a great shortcut here, but shredded leftover chicken or even canned chicken can work in a pinch.
Buffalo Sauce: This gives the casserole its signature spicy flavor. Feel free to adjust the amount or use a mild sauce if you prefer less heat. You can also mix your own buffalo sauce using hot sauce and butter.
Cheeses: A combo of cheddar and mozzarella adds creaminess and gooey texture, while crumbled blue cheese on top gives a salty tang. If you’re dairy-free, try vegan cheese alternatives or nutritional yeast for a cheesy flavor.
How Do You Get the Perfect Cauliflower Texture Without It Getting Mushy?
Cauliflower can easily become mushy if overcooked. Here’s how to keep it tender but firm:
- Boil the florets for just 4-5 minutes until they’re slightly softened, not fully cooked.
- Drain immediately and pat dry with paper towels to remove excess moisture.
- Don’t skip drying—too much water can make the casserole watery and soggy.
- If you prefer, roast the cauliflower instead of boiling; roasting enhances flavor and keeps texture firmer.
Equipment You’ll Need
- Large pot – I use it to quickly boil the cauliflower; it’s easy and saves time.
- Mixing bowl – perfect for combining all ingredients until evenly coated.
- 9×13-inch casserole dish – ideal for baking and evenly cooking the casserole.
- Measuring cups and spoons – for accurate measurement of sauces, cheese, and seasonings.
- Silicone spatula or large spoon – helpful for mixing everything smoothly.
- Oven mitts – to handle the hot dish safely when removing from the oven.
Flavor Variations & Add-Ins
- Swap chicken for cooked turkey or shredded pork for different protein options.
- Add cooked bacon bits or sliced jalapeños for extra flavor and heat.
- Mix in chopped celery or carrots for added crunch and sweetness.
- Use a different cheese like pepper Jack or Monterey Jack to tweak the flavor profile.

Step-by-Step Instructions:
1. Prepare Your Oven and Dish:
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish with olive oil or cooking spray to prevent sticking.
2. Cook the Cauliflower:
Bring a large pot of salted water to a boil. Add the cauliflower florets and cook for about 5 minutes, just until they are a little tender but still firm. Drain thoroughly and pat dry with paper towels to avoid excess moisture.
3. Mix Everything Together:
In a large bowl, combine the cooked cauliflower, shredded chicken, cheddar cheese, mozzarella cheese, buffalo wing sauce, and ranch or blue cheese dressing. Stir gently until everything is evenly mixed and coated.
4. Bake the Casserole:
Spread the mixture evenly into your prepared casserole dish. Place it in the oven and bake for 20 to 25 minutes, or until the cheese melts and bubbles nicely.
5. Add Final Touches:
Remove from the oven and sprinkle the crumbled blue cheese on top. Garnish with sliced green onions and chopped parsley or cilantro for fresh flavor and a pop of color.
6. Serve and Enjoy:
If you like, drizzle a little extra buffalo sauce over the casserole before serving. Let it cool for a few minutes, then serve warm with celery sticks and ranch or blue cheese dressing for dipping.
Can I Use Frozen Cauliflower for This Recipe?
Yes, you can use frozen cauliflower, but be sure to thaw and drain it well to avoid extra moisture. Pat it dry with paper towels before mixing to keep the casserole from becoming watery.
Can I Prepare This Casserole Ahead of Time?
Absolutely! Assemble the casserole and refrigerate it for up to 24 hours before baking. Just bring it to room temperature for about 20 minutes before placing it in the oven to ensure even cooking.
How Should I Store Leftovers?
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave, adding a splash of buffalo sauce or dressing to keep it moist.
Can I Make This Recipe Spicier or Milder?
Definitely! Adjust the amount of buffalo sauce to your heat preference, or use a mild buffalo sauce for less spice. You can also add extra blue cheese or ranch dressing to tone down the heat.
