Ingredients & Why They Work

Each component here has a distinct purpose — the sweet potatoes give a tender, naturally sweet base while the chicken soaks up that tangy buffalo sauce perfectly. Roasting the broccoli alongside adds that nice veggie crunch and color. I always recommend fresh, quality ingredients because you can really taste the difference.

Boneless Chicken Breasts: Easy to cube and cook evenly; they absorb buffalo sauce so well and stay juicy if you don’t overcook.
Sweet Potatoes: Their natural sweetness contrasts the spicy buffalo, and you can keep the skin on for extra fiber and nutrients.
Broccoli: Adds a fresh, slightly bitter crunch to balance the richness; cut into small florets so they roast quickly.
Buffalo Sauce: The star of the flavor party; I love New Primal for its bold taste, but Frank’s works just as well.
Avocado or Olive Oil: Helps everything roast up golden and keeps the casserole moist without greasiness.
Seasonings (Salt, Pepper, Garlic Powder): Simple but essential for layering flavors throughout the dish.
Shredded Cheddar Cheese: Melts over the top for that ooey-gooey finish everyone craves.
Green Onion: Provides a fresh bite and a pop of color at the end.
Cooked Turkey Bacon: Adds a smoky crunch that’s optional but definitely worth it.
Ranch Dressing: Drizzled on top or served on the side balances the heat and adds creaminess.

Make It Your Way

What I love most about this Buffalo Chicken Sweet Potato Casserole Recipe is how you can tailor it to suit your mood or pantry. I sometimes switch up the proteins or add more veggies when I’m feeling adventurous. Don’t hesitate to make it your own; that’s part of the fun!

Variation: I’ve tried adding shredded rotisserie chicken when I’m short on time, and it still tastes fantastic with the buffalo flavor.
Vegetarian Option: Swap chicken for extra broccoli and even some roasted cauliflower instead — just use your favorite hot sauce to keep the kick.
Spice Level: Adjust the buffalo sauce quantity or use a milder sauce if you’re cooking for kids or sensitive palates.
Dairy-Free: Go dairy-free by skipping the cheese or using a vegan cheese alternative, and swap ranch for a cashew cream drizzle.

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

Step 1: Prep Your Ingredients

Start by cutting your chicken breasts into bite-sized cubes, and dice the sweet potatoes into small, even pieces so they roast evenly. I usually leave the skin on the sweet potatoes since it adds nice texture and nutrients, but peeling is totally fine if you prefer. Chop the broccoli into small florets that’ll cook through in the same amount of time as the chicken. Having everything prepped really smooths the cooking process and ensures nothing is over or underdone.

Step 2: Toss Sweet Potatoes with Buffalo Sauce

In a small bowl, whisk together the buffalo sauce, avocado oil, salt, pepper, and garlic powder. Take half of this mixture and pour it over the sweet potatoes in a large bowl, then toss everything together until the sweet potatoes are well coated. This step infuses the potatoes with tons of flavor from the start.

Step 3: Roast Sweet Potatoes

Spread the coated sweet potatoes evenly in a greased 9×13 casserole dish and roast in your preheated 425°F oven for 30 minutes. About halfway through, flip or stir the sweet potatoes carefully so they get browned on all sides — this caramelization adds incredible depth. Keep an eye on them so they don’t burn; you want tender, lightly crisped edges.

Step 4: Add Chicken and Broccoli

While those are roasting, toss the cubed chicken and broccoli florets back in that big mixing bowl you used for the sweet potatoes. Add the remaining buffalo sauce mixture and toss until everything is coated evenly. After the 30 minutes are up on the sweet potatoes, spread this chicken and broccoli mix over them. This way, everything finishes roasting together and the buffalo flavor ties it all into one cohesive dish.

Step 5: Final Baking and Toppings

Pop the casserole back in the oven and bake for another 20-25 minutes until the chicken reaches 165°F inside and the broccoli is tender but still bright green. Then, pull it out and sprinkle shredded cheddar, chopped green onion, and the cooked turkey bacon over the top. Put it back in the oven for 5 minutes more, just until the cheese melts beautiful and bubbly. Let it cool a bit before serving — that cheese and bacon topping is worth the wait!

Tips from My Kitchen

Even Cubing: Cutting chicken and potatoes into similar sizes makes cooking times uniform and avoids undercooked bites.
Use a Meat Thermometer: I always check the chicken with a meat thermometer to avoid drying it out or serving undercooked poultry.
Buffalo Sauce Balance: Don’t be shy to taste and adjust buffalo sauce to your heat preference before tossing—it’s easier to ramp up heat later than tone it down.
Roasting Time Watch: Keep an eye on the sweet potatoes’ tenderness and don’t over-roast the broccoli so it keeps that little snap and bright color.

How to Serve Buffalo Chicken Sweet Potato Casserole Recipe

Garnishes

I always drizzle some ranch dressing on top — it cools down the heat perfectly and adds creaminess that makes every bite irresistible. Sometimes I’ll sprinkle extra green onions or a handful of chopped fresh cilantro for a fresh twist. Blue cheese crumbles are a classic topping that pairs incredibly well if you like that tang.

Side Dishes

Even though this casserole packs quite the punch on its own, I love serving it alongside a simple green salad with a zesty vinaigrette or crunchy celery sticks to channel those classic buffalo wing vibes. If I want to keep things cozy, a warm garlic bread or crusty roll always rounds out the meal.

Creative Ways to Present

For a party, try this recipe in small individual ramekins and broil the cheese topping until golden brown—that always wows guests. Another fun idea is serving it over cauliflower rice or alongside a grain salad for a hearty bowl-style meal. Perfect for game day or casual gatherings where everyone digs in family-style!

Make Ahead and Storage

Storing Leftovers

I let the casserole cool completely before popping it into an airtight container in the fridge. It lasts up to 5 days, which made for some pretty awesome next-day lunches. Just reheat gently so the chicken stays tender and the cheese melts again.

Freezing

Freezing works well, too! I freeze individual portions wrapped tightly in plastic wrap and then foil. When ready, thaw overnight in the fridge and just warm it in the oven at 350°F until heated through. The texture is still great, and the flavors hold up surprisingly well.

Reheating

My go-to reheating method is to let leftovers come to room temp, then warm them in the oven or toaster oven at 350°F. This keeps that crispy cheese topping intact and prevents the casserole from drying out, unlike the microwave which can make it a bit soggy.

FAQs

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

Yes, you can use frozen broccoli, but be sure to thaw and drain it well to avoid excess moisture making the casserole soggy. I recommend toss it with some buffalo sauce and give it a quick roast or sauté before adding it to the casserole.
Is this casserole spicy? Can I make it milder?

The heat level depends on the buffalo sauce you choose and how much you use. If you prefer a milder dish, reduce the sauce amount or opt for a milder buffalo sauce brand. Adding ranch or blue cheese on top also helps tame the heat while keeping flavor intact.
Can I prep this recipe ahead of time?

Absolutely! You can prep all ingredients, toss everything in the casserole dish, cover tightly, and refrigerate for up to a day before baking. Just add cheese and bacon toppings during the last 5 minutes of baking for maximum freshness.
What can I substitute for turkey bacon?

If you don’t have turkey bacon, actual bacon or even smoked sausage bits work wonderfully. For a vegetarian twist, try smoked tempeh or omit it altogether and bulk up on extra cheese and green onions.
