How to Make Buffalo Chicken Sweet Potato Casserole

Step 1: Preheat and Prepare

Preheat your oven to 425°F (220°C). Lightly grease a 9×13-inch casserole dish to prevent sticking.

Step 2: Make the Buffalo Sauce Mixture

In a small bowl, whisk together buffalo sauce, olive oil, garlic powder, onion powder, salt, and black pepper until well combined.

Step 3: Roast the Sweet Potatoes

Place cubed sweet potatoes in a large bowl and toss with half of the buffalo sauce mixture until evenly coated. Spread them in the prepared baking dish and roast for 30 minutes, flipping halfway through to ensure even cooking.

Step 4: Prepare Chicken and Broccoli

In the same bowl, combine chicken cubes and broccoli florets. Add the remaining buffalo sauce mixture and toss until everything is well coated.

Step 5: Add and Bake

After the sweet potatoes have roasted for 30 minutes, remove the dish from the oven. Add the buffalo-coated chicken and broccoli on top. Return to the oven and bake for an additional 20–25 minutes, until the chicken is fully cooked.

Step 6: Add Cheese and Broil

Sprinkle shredded cheddar cheese evenly over the casserole. Broil for 3–5 minutes until the cheese is melted, bubbly, and slightly golden.

Step 7: Garnish and Serve

Remove from the oven and garnish with chopped green onions. Let it rest briefly before serving.

Tips for Success

• Cut sweet potatoes into small, even cubes for faster, uniform cooking
• Flip the potatoes halfway through roasting to avoid burning
• Don’t overcrowd the pan—spread ingredients evenly for proper roasting
• Use a good-quality buffalo sauce for the best flavor
• Broil carefully at the end to avoid burning the cheese
