How to Make Jalapeño Buffalo Chicken Casserole: Whole30, Keto, Paleo, GF Recipe

Step 1: Prep Your Ingredients and Chicken

First things first, get your chicken cooked and shredded. If you don’t have pre-cooked chicken, I recommend baking your chicken breasts at 400°F for about 25 minutes while you prep the vegetables and make the sauce. It’s a handy trick I discovered that saves precious time. Meanwhile, dice your peppers, onion, jalapeños, and carrots—everything should be bite-sized for even cooking and a balanced bite in every forkful.

Step 2: Mix Up the Creamy Buffalo Sauce

In a small bowl, whisk together the coconut cream, buffalo sauce, ranch, minced garlic, salt, and pepper. I love how the coconut cream adds a subtle sweetness and smooth texture that tones down the heat just enough. Take your time mixing so the sauce is silky and fully blended.

Step 3: Combine Everything in Your Casserole Dish

Toss your cooked shredded chicken, chopped veggies, and frozen cauliflower rice into a large casserole dish. Pour that luscious buffalo cream sauce over the top, then gently fold everything together with two forks or tongs. You want the sauce to coat every bit but keep the ingredients distinct. Then, smooth it out into an even layer to get an even bake.

Step 4: Bake Until Bubbling and Gorgeous

Bake your casserole at 400°F for 45 minutes. If you like a slightly crispy top, leave it in a bit longer but keep an eye so it doesn’t dry out. When it’s done, the edges should be bubbly and just a bit golden. When I bake this, my kitchen starts smelling amazing, and I can’t wait to dig in!

Step 5: Garnish and Serve

Once out of the oven, drizzle with a little extra buffalo sauce or ranch and sprinkle with fresh green onions and jalapeños if you like that extra kick. The garnishes add freshness and color that really elevate the dish visually and flavor-wise.

Garnishes

I love topping mine with fresh chopped green onions because they add a beautiful pop of color and a mild onion flavor that contrasts with the spicy casserole. Extra sliced jalapeños bring heat and crunch for the spice lovers. A drizzle of ranch or buffalo sauce after baking finishes the dish perfectly.

Side Dishes

This casserole is pretty filling on its own, but I like pairing it with a simple side salad—crisp mixed greens with a light vinaigrette to balance the richness of the casserole. Sometimes, I serve it alongside roasted asparagus or steamed green beans to keep things green and fresh on the plate.

Creative Ways to Present

For special occasions, I’ve served this casserole in mini ramekins for individual portions—they look fancy, and everyone loves their own personal dish. You can also sprinkle crunchy pecans or pumpkin seeds on top before baking for a fun twist in texture. It’s a great way to impress guests without extra effort.

Make Ahead and Storage

Storing Leftovers

I store leftovers in an airtight container in the fridge for up to 4 days. When I do this, the flavors actually deepen overnight, making leftovers taste even better the next day. Just remember to keep it sealed well to maintain the creamy texture.

Freezing

This Jalapeño Buffalo Chicken Casserole freezes beautifully if you want to save some for later. I let it cool completely, then portion it into freezer-safe containers or bags. When frozen properly, it keeps well for about 2-3 months without losing flavor or texture.

Reheating

To reheat, I usually warm individual portions in the microwave, covered loosely so it stays moist. For larger portions, reheating in a 350°F oven until warmed through works great and helps bring back a little crispness on top. Adding a splash of water or broth before reheating keeps it from drying out.
