Ingredients & Why They Work

Each ingredient in this Buffalo Chicken Sweet Potato Casserole Recipe plays a delicious role, and I’ll share why I picked them and a few tips so you get the best results. The combination is really about layering textures and flavors that’ll make you want seconds.

Boneless chicken breasts: Cubed for even cooking and to soak up that buffalo sauce goodness.
Sweet potatoes: Their natural sweetness builds a beautiful contrast with the heat; leaving the skin on adds extra nutrition and texture.
Broccoli: Adds a fresh, green crunch and balances the richness.
Buffalo sauce: I lean toward New Primal for a cleaner ingredient list, but Franks is the classic go-to; both pack the right zing.
Avocado or olive oil: Helps everything roast up beautifully and adds healthy fat.
Seasonings (salt, pepper, garlic powder): These basic spices give a round, savory backdrop for the bold flavors.
Shredded cheddar cheese: Melts over the top to create an indulgent finish.
Chopped green onion: For a mild sharpness and fresh color pop.
Cooked turkey bacon: Adds crunch and smoky depth without overpowering.
Ranch dressing: Optional but highly recommended for drizzling at the end—it cools off the heat.

Tweak to Your Taste

One of my favorite things about this Buffalo Chicken Sweet Potato Casserole Recipe is how flexible it is. I often play around with the toppings or swap ingredients based on what’s in my fridge or the season. Don’t hesitate to make it your own!

Variation: Sometimes I use chicken thighs instead of breasts for juicier bites—also great if you want a richer flavor.
For extra heat: Add some sliced jalapeños or a sprinkle of cayenne when mixing your buffalo sauce.
Make it vegetarian: Swap the chicken for roasted chickpeas and use a vegetarian bacon or omit it altogether.
Dairy-free: Skip the cheese and ranch or use dairy-free alternatives—your casserole will still be yummy and creamy thanks to the buffalo sauce and roasted veggies.

Step-by-Step: How I Make Buffalo Chicken Sweet Potato Casserole Recipe

Step 1: Prep and start roasting the sweet potatoes

First things first, preheat your oven to 425°F and grease your 9×13 casserole dish. I like to cut my sweet potatoes into small, even cubes so they cook up nicely and get tender but still hold their shape. Toss half your buffalo sauce mixture (which is buffalo sauce, avocado oil, salt, pepper, and garlic powder mixed together) with the sweet potatoes, making sure every cube is coated. Spread them out in the casserole dish and pop them in the oven for 30 minutes. Flip them halfway through so they brown evenly. Roasting the sweet potatoes first gives you that lovely caramelized flavor that balances the buffalo heat.

Step 2: Toss chicken and broccoli in buffalo sauce

While the sweet potatoes are roasting, cube your chicken breasts and cut broccoli into small florets. In the large mixing bowl that once held the sweet potatoes, add the chicken, broccoli, and the remaining buffalo sauce mixture. Toss everything well so the chicken and broccoli are fully coated. This step ensures all your flavors come through perfectly by giving everything a spicy, tangy hug.

Step 3: Combine and finish baking

Once the sweet potatoes hit the 30-minute mark, take the casserole dish out and layer your buffalo-coated chicken and broccoli on top. Slide it back into the oven for another 20-25 minutes, until the chicken hits an internal temperature of 165°F—always trust a meat thermometer if you have one, it’s a game changer! When your timer goes off, pull the casserole out and immediately sprinkle on cheese, green onion, and cooked turkey bacon. Pop it back in for just 5 more minutes so the cheese can melt into that gooey perfection we all crave.

Step 4: Rest and garnish

Let the casserole cool for a few minutes after baking—the flavors need a moment to settle. Then drizzle with ranch or your favorite blue cheese dressing. The creamy dressing is like the perfect counterpoint to the spice and warmth, so don’t skip this final flourish unless you’re feeling bold! Serve it up warm.

Pro Tips for Making Buffalo Chicken Sweet Potato Casserole Recipe

Use a Meat Thermometer: To avoid dry chicken, check for 165°F internal temperature rather than guessing by appearance.
Cut Evenly: Cutting sweet potatoes and chicken into uniform pieces ensures everything cooks evenly and on time.
Buffalo Sauce Balance: I start with half the sauce on sweet potatoes to keep them from getting soggy, then toss the chicken and broccoli with the other half for the best texture.
Don’t Skip Resting: Letting the casserole cool slightly helps the cheese set and flavors marry perfectly before serving.

How to Serve Buffalo Chicken Sweet Potato Casserole Recipe

Garnishes

I always finish my Buffalo Chicken Sweet Potato Casserole Recipe with a drizzle of ranch dressing and a sprinkle of fresh green onions. The ranch cools the spicy buffalo notes beautifully, and the green onions add a subtle crunch and that fresh, savory pop. Sometimes I’ll throw on a handful of chopped cilantro or even a squeeze of lime for a bright twist that wakes up the dish. And don’t forget crispy turkey bacon for that smoky crunch—it’s my favorite topping!

Side Dishes

Since this casserole is pretty filling with protein, veggies, and carbs all in one, I like to keep side dishes light. A simple crisp green salad with a lemon vinaigrette or some steamed green beans is perfect. If you want something cozy, garlic bread or soft dinner rolls pair well too—especially when you’ve got leftovers to enjoy the next day.

Creative Ways to Present

For casual family dinners, I serve this casserole straight from the dish for that comfy “sit down and dig in” vibe. But if I’m hosting friends or want to impress at a potluck, I’ll bake it in individual ramekins or small skillets—each portion gets its own crunchy cheese and bacon topping. It’s a fun way to personalize servings and adds a restaurant-like feel right at your table.

Make Ahead and Storage

Storing Leftovers

Buffalo Chicken Sweet Potato Casserole keeps really well in the refrigerator for up to five days. I store leftovers in an airtight container and I’ve found that the flavors even deepen a bit after sitting overnight. It’s super handy for quickly reheating lunches or easy dinners throughout the week.

Freezing

You can definitely freeze this casserole for longer storage. Just make sure it’s fully cooled, then freeze in a tightly sealed container or foil-covered baking dish. When you’re ready, thaw overnight in the fridge and reheat in the oven until warmed through. The texture stays great, especially if you add fresh toppings after reheating.

Reheating

I recommend reheating leftovers in the oven at 350°F rather than the microwave—this keeps the chicken juicy and the sweet potatoes firm without getting mushy. Keep it covered with foil to prevent drying out, and add your cheese and bacon toppings fresh after reheating for the best flavor.

FAQs

Can I use frozen broccoli in this Buffalo Chicken Sweet Potato Casserole Recipe?

Yes, you can! Just be sure to thaw and drain it well first to avoid excess moisture that might make the casserole watery. Pat it dry with paper towels before tossing with the buffalo sauce and chicken.
What can I substitute for buffalo sauce?

If you’re not a fan of buffalo sauce or want something milder, you can use barbecue sauce mixed with a touch of hot sauce or even a spicy sriracha mayo for a different twist. Just adjust the amount to suit your preferred heat level.
Is this casserole spicy?

It has a pleasant, moderate heat level thanks to the buffalo sauce. If you prefer it milder, use less buffalo sauce, or add more ranch or cheese to balance it out. Conversely, ramp up the heat with extra hot sauce or fresh chilis.
Can I make this recipe ahead of time?

Absolutely! You can prep everything up to the point of baking, then cover and refrigerate the casserole dish overnight. Bake as directed the next day, adding extra baking time if it’s coming straight from the fridge.
