Step‑by‑Step Instructions for Buffalo Chicken Sweet Potato Casserole
Step 1: Preheat the Oven
Start by preheating your oven to 425°F (220°C). While the oven warms up, take a moment to grease a 9×13 casserole dish thoroughly, ensuring the coating is even to prevent sticking. This will provide a perfect base for your flavorful Buffalo Chicken Sweet Potato Casserole.
Step 2: Prepare the Vegetables and Chicken
Cube the boneless chicken breasts into bite-sized pieces, and set aside. Next, peel and cube the sweet potatoes, then chop the broccoli into small florets. This ensures that everything cooks evenly, creating a balanced texture and flavor throughout the casserole.
Step 3: Mix the Buffalo Sauce
In a small bowl, combine the buffalo sauce with avocado oil, salt, pepper, and garlic powder. Mix these ingredients until well blended, creating a flavorful sauce infused with zesty goodness. This will provide that signature kick to the chicken and sweet potatoes as they roast.
Step 4: Coat the Sweet Potatoes
In a large mixing bowl, add the cubed sweet potatoes and half of the buffalo sauce mixture. Toss everything together until the sweet potatoes are well-coated with the sauce. The vibrant color will signal that you’re on the right track to a delicious Buffalo Chicken Sweet Potato Casserole.
Step 5: Roast the Sweet Potatoes
Pour the coated sweet potatoes into your greased casserole dish, spreading them out evenly. Roast in the preheated oven for 30 minutes, and remember to flip them halfway through to ensure they achieve a golden, tender texture.
Step 6: Combine Chicken and Broccoli
While the sweet potatoes roast, return to the bowl used earlier and add the cubed chicken and chopped broccoli. Pour in the remaining buffalo sauce mixture and toss well to coat. This step ensures each piece is packed with flavor, bringing the dish together beautifully.
Step 7: Layer the Chicken and Broccoli
Once the sweet potatoes are roasted, carefully layer the chicken and broccoli mixture over the sweet potatoes in the casserole dish. Spread them evenly to ensure all the flavors meld while baking, creating a hearty base for your Buffalo Chicken Sweet Potato Casserole.
Step 8: Bake the Casserole
Return the casserole to the oven, and bake for an additional 20-25 minutes, or until the chicken reaches an internal temperature of 165°F (74°C). The excitement builds as you wait for the luscious, savory aroma to fill your kitchen.
Step 9: Add the Toppings
After baking, remove the casserole from the oven and sprinkle your desired amount of cheese, green onion, and turkey bacon on top. Place it back in the oven for around 5 minutes just until the cheese melts beautifully, adding a creamy finish to your dish.
Step 10: Cool and Serve
Finally, allow the casserole to cool slightly before digging in. This brief resting period enhances the flavors. Optionally, drizzle some ranch or blue cheese dressing over your servings to add a creamy, tangy twist to your delicious Buffalo Chicken Sweet Potato Casserole.

Make Ahead Options
