Easy Buffalo Chicken Casserole (Cheesy, Spicy, 40‑Minute Dinner)
This buffalo chicken casserole takes everything you love about classic wing flavor and turns it into a cheesy baked pasta dinner that’s on the table in about 40 minutes. No frying, no deep‑fried cleanup, just tender pasta, shredded chicken, and a spicy cream sauce under a blanket of melted cheddar.

It’s the kind of dish that makes a weeknight feel a little more fun, especially if you’re a buffalo sauce fan. Serve it with celery sticks and ranch on the side and watch it disappear.
What Makes This Casserole So Good
The buffalo sauce brings heat without being overpowering, balanced by a little cream cheese and sour cream in the sauce. Shredded rotisserie chicken cuts the prep time down to almost nothing, and the pasta bakes up tender in all that spice.
Every bite has that tangy, buttery buffalo flavor with a gooey cheese pull that makes it feel indulgent but still easy enough for a Tuesday.
Ingredients

- 12 oz rotini pasta: any short pasta works, like penne or fusilli
- 3 cups shredded cooked chicken: rotisserie chicken saves time
- 8 oz cream cheese, softened: full‑fat for the creamiest sauce
- ½ cup sour cream: adds tang and richness
- ⅔ cup buffalo wing sauce: use your favorite brand, like Frank’s
- 2 cups shredded cheddar cheese, divided: half for the casserole, half for the top
- 2 green onions, sliced: for garnish
- Salt and pepper: to taste
Variations / Substitutions
- Use ranch seasoning: stir 1 tablespoon dry ranch mix into the sauce for a cool, herby note
- Swap the cheese: mozzarella, Monterey Jack, or pepper jack all melt beautifully
- Lighten it up: use Neufchâtel cream cheese and reduced‑fat sour cream
- Add crunch: crush some tortilla chips or butter crackers over the top before baking
- Go blue cheese: swap half the cheddar for crumbled blue cheese if that’s your thing

How to Make Buffalo Chicken Casserole
Step 1: Cook the Pasta

Preheat your oven to 375°F (190°C) and bring a large pot of salted water to a boil. Add the 12 oz rotini and cook until just al dente, about 2 minutes less than the package says. Drain and set aside.
The pasta will finish cooking in the oven, so you want it slightly firm now. If you cook it all the way through, it will turn mushy after baking.
Step 2: Whisk the Buffalo Sauce

In a large bowl, microwave the 8 oz cream cheese for 20 to 30 seconds until very soft. Add the ½ cup sour cream, ⅔ cup buffalo wing sauce, a pinch of salt, and a few grinds of pepper. Whisk until smooth and combined.
The sauce should be pale orange and pourable. It will look a little thin, but it thickens up once it bakes with the pasta.
Step 3: Assemble the Casserole

Stir 1 cup of the shredded cheddar into the sauce, then fold in the drained pasta and the 3 cups shredded chicken until everything is evenly coated. The mixture should be saucy and bright orange.
Transfer it to a greased 9×13‑inch baking dish and spread it into an even layer. This is the last time you’ll see it before it comes out of the oven all bubbly, so give it a quick taste and add a touch more salt or wing sauce if you want more kick.
Step 4: Top with Cheese and Bake

Sprinkle the remaining 1 cup cheddar evenly over the top. Bake for 20 to 25 minutes, until the cheese is melted and the edges are bubbling.
If you like a browned, crispy top, switch on the broiler for the last 1 to 2 minutes. Just keep an eye on it so it doesn’t burn.
Step 5: Scoop into Bowls

Let the casserole rest for 5 minutes after it comes out of the oven so the sauce can set up a bit. Scatter the sliced green onions over the top, then scoop generous portions into bowls.
The cheese will be stretchy and the sauce will cling to every piece of pasta. Serve right away while it’s still hot.
A Few Tips Before You Start
- Grab a rotisserie chicken.: Shred it while it’s still warm, and you’ll have tender, juicy pieces with zero extra cook time.
- Undercook the pasta on purpose.: A 2‑minute head start in boiling water means it won’t turn to mush after 25 minutes in the oven.
- Let it rest.: Those 5 minutes off the heat keep the casserole from becoming soupy when you serve it.
- Double it for a crowd.: Use a deep 9×13 dish and expect a slightly longer bake time, about 30 to 35 minutes.
Bake times by dish size:
| Dish Size | Bake Time |
|---|---|
| 9×13 inch, glass or metal | 20–25 mins |
| 8×8 inch (deeper) | 30–35 mins |
| Individual ramekins | 15–20 mins |
Storing Leftovers
Refrigerate leftovers in a covered container for up to 3 days. Reheat individual portions in the microwave, or warm the whole casserole in a 350°F (175°C) oven for about 15 minutes.
What to Serve with Buffalo Chicken Casserole
Crisp celery sticks and a bowl of ranch dressing are the classic cool‑down pair, no matter how fancy the casserole. A simple coleslaw with a vinegar‑based dressing cuts through the richness, and a side of roasted broccoli or green beans rounds it out into a full meal.
Frequently Asked Questions
Can I use uncooked chicken?
Yes, but cook it first. Sauté diced raw chicken with a little oil and salt until cooked through, then shred or chop and use as directed.
Can I assemble this ahead of time?
Absolutely. Assemble the casserole, cover, and refrigerate for up to 24 hours. Bake straight from the fridge, adding 5 to 10 minutes to the bake time.
What if I don’t have buffalo wing sauce?
Mix ½ cup hot sauce with 2 tablespoons melted butter and a pinch of garlic powder. It’s not exact, but it gets you close.
Can I freeze it?
Yes. Assemble the casserole without baking, wrap it tightly, and freeze for up to 2 months. Thaw overnight in the fridge, then bake as directed.
