Step-by-Step Cooking Instructions
Start by preheating your oven to 375 degrees Fahrenheit. While it heats up, grab a 9 by 9 inch baking dish and lightly grease it with olive oil or a quick spray of nonstick cooking spray.
Use cooked chicken breast for best results. If you have leftovers from another meal or a store-bought rotisserie chicken, this is the perfect time to use them. Shred the chicken using two forks or a stand mixer with a paddle attachment. If your chicken is not already cooked, simply bake or pan-cook about one pound of boneless chicken breasts, then shred once cooled.
In a large mixing bowl, combine buffalo sauce, cream cheese, and sour cream. Stir until smooth and creamy. This will be the rich and spicy base that ties the casserole together. Add onion powder, garlic powder, paprika, and salt and pepper. Mix thoroughly so every bite has that signature tangy kick and warmth.
Fold the shredded chicken into the sauce mixture, making sure it is evenly coated. Add half of the cheddar cheese and half of the mozzarella cheese into the mixture and stir again. The cheese melts inside as it bakes and makes the casserole extra creamy.
Transfer everything into your prepared baking dish. Spread it out evenly with a spoon or spatula. Sprinkle the remaining cheddar and mozzarella cheese on top. Bake in your preheated oven for 20 to 25 minutes or until the cheese on top is fully melted and bubbly. The edges should start to turn golden brown.
Once baked, remove the dish from the oven and let it sit for five minutes before serving. This helps everything settle and makes it easier to scoop. Serve it hot and enjoy every cheesy, spicy bite.
Tips for Customizing the Recipe

This buffalo chicken casserole is very flexible. Here are a few ways to make it your own:
You can mix in chopped spinach, diced bell peppers, or grated zucchini to increase the nutrition without changing the flavor too much. Just stir them in with the chicken and sauce before baking.
If you are cutting back on carbs, serve the casserole over cauliflower rice or use spiralized zucchini as a base.
Not a buffalo fan? Swap the buffalo sauce with barbecue sauce for a smoky version or try ranch dressing for a creamy and mild twist.
Add hot sauce, red pepper flakes, or chopped jalapeños if you like more heat in your food.
For those following a keto diet, replace the sour cream with full-fat Greek yogurt. You can also skip any bread-based sides and serve with roasted low-carb vegetables.
