Ingredients You’ll Need

You’ll be amazed at how a small handful of ingredients come together to create such bold flavors in this Buffalo Chicken Sweet Potato Casserole. Each item has a purpose, from crunchy veggies to creamy cheese, making every bite exciting and deeply satisfying.

Chicken Breasts: Lean, protein-packed cubes of chicken soak up the zesty buffalo sauce and stay incredibly juicy as they bake.
Sweet Potatoes: These hearty cubes bring a natural sweetness that balances out the spicy sauce beautifully.
Broccoli: Fresh florets add earthy flavor and plenty of color, becoming tender and lightly roasted in the oven.
Buffalo Sauce: Use your favorite for heat and tang; this is the real flavor-maker for the casserole.
Avocado Oil or Olive Oil: Helps everything roast up golden while also deepening the overall flavor.
Salt and Pepper: Essential seasonings to enhance the core ingredients without overpowering them.
Garlic Powder: Adds aromatic, savory depth to each bite — don’t skip this boost!
Shredded Cheddar Cheese: Melts into a gooey, craveable topping that brings everything together.
Chopped Green Onion: Sprinkled fresh on top for a bright pop of flavor and color contrast.
Cooked Turkey Bacon: Crumbled for a smoky, crispy element that puts this casserole over the top.
Drizzle of Ranch: The cool, creamy finish against spicy buffalo sauce is pure magic.

How to Make Buffalo Chicken Sweet Potato Casserole

Step 1: Preheat and Prep

Start by preheating your oven to 425°F, ensuring it’s nice and hot for roasting. Lightly grease a 9×13 casserole dish — this keeps the sweet potatoes from sticking, and helps with easy cleanup later!

Step 2: Chop the Basics

Dice the chicken breasts into bite-sized pieces, cube the sweet potatoes (peeling optional), and cut your broccoli into small, even florets. Keeping everything similar in size means it all cooks at the same pace, so you don’t end up with undercooked chunks or mushy veggies.

Step 3: Mix the Magic Sauce

In a small bowl, whisk together the buffalo sauce, your preferred oil, salt, pepper, and garlic powder. This spicy and savory mixture is what transforms simple ingredients into the unforgettable Buffalo Chicken Sweet Potato Casserole.

Step 4: Coat Sweet Potatoes

Toss the sweet potato cubes with half of the buffalo sauce mixture in a large bowl until every piece is well coated. This step ensures the potatoes get a flavorful head start while they roast first.

Step 5: First Bake

Spread the sauced sweet potatoes in your prepared casserole dish and roast for 30 minutes, stirring once halfway through. They’ll soften and begin to caramelize, soaking in all the spicy goodness.

Step 6: Marinate Chicken and Broccoli

While the sweet potatoes are roasting, add the cubed chicken and broccoli florets to the same bowl you just used, and toss them with the rest of that luscious buffalo sauce mix. Using the same bowl brings extra flavor — no drop of sauce goes to waste here!

Step 7: Add the Rest

Once the timer dings on those sweet potatoes, carefully remove the dish from the oven. Scatter your buffalo-coated chicken and broccoli over the top. This layered approach means each ingredient cooks perfectly and gives great texture in every bite.

Step 8: Final Bake

Return the casserole to the oven and bake for another 20-25 minutes, or until the chicken is cooked through (an internal temp of 165°F is perfect) and everything smells amazing.

Step 9: The Finishing Touches

Take out the casserole momentarily to shower the top in shredded cheddar, chopped green onion, and your cooked turkey bacon. Slide it back in for just five minutes so the cheese gets irresistibly melty and the bacon lightly crisps.

Step 10: Serve and Enjoy

Allow your Buffalo Chicken Sweet Potato Casserole to rest for a few minutes so it sets up and is easier to scoop. Finish with a drizzle of ranch or even a sprinkle of blue cheese — now it’s ready to impress for dinner!

Creative Ways to Present

For game day or parties, scoop this casserole into individual ramekins for easy, grab-and-go servings. You can also stuff it inside baked sweet potato skins or serve atop a bed of crisp lettuce for a lower-carb twist that feels fresh and fun.

Make Ahead and Storage

Storing Leftovers

Leftovers of Buffalo Chicken Sweet Potato Casserole keep like a dream! Store them in an airtight container in the refrigerator for up to 4 days. The flavors deepen even more overnight, making lunch the next day something to look forward to.

Freezing

This dish is freezer-friendly: simply cool completely, transfer to a freezer-safe dish or portion into individual servings, and freeze for up to 2 months. It’s a lifesaver for busy weeks when you crave something homemade.

Reheating

Rewarm individual portions in the microwave, or return larger amounts to the oven at 350°F until hot and bubbly. If it’s looking a little dry, drizzle on a touch more buffalo sauce or a little olive oil before reheating to revive all that saucy, cheesy goodness.

FAQs

Can I use rotisserie chicken instead of raw chicken?

Absolutely! Just stir in shredded rotisserie chicken in place of raw chicken in Step 6, and reduce the final baking time to about 15 minutes so it doesn’t dry out. This shortcut makes Buffalo Chicken Sweet Potato Casserole even quicker to whip up.

How spicy is this casserole?

The heat can easily be adjusted depending on which buffalo sauce you pick. For a little extra spice, go for a hot variety or drizzle on more sauce at serving; for a milder version, use a more mild buffalo or mix in some ranch dressing to tame the heat.

Can I make this casserole dairy-free?

Yes, you can swap in your favorite dairy-free cheddar cheese alternative and use a vegan ranch dressing. Everything else about Buffalo Chicken Sweet Potato Casserole is naturally gluten and dairy-free friendly if you make those simple swaps!

Is it possible to swap the potatoes?

If you prefer, you can use regular russet or Yukon gold potatoes in place of sweet potatoes, but the subtle sweetness from sweet potatoes really rounds out the bold buffalo flavor. Try half and half for a fun twist!

Can I add other vegetables?

Definitely! Cauliflower, carrots, or bell peppers all roast up beautifully in this dish and will add bright color and crunch. Just keep vegetable pieces about the same size as the chicken and sweet potatoes for even cooking.
