Ingredients You’ll Need

Each ingredient in this Jalapeño Buffalo Chicken Casserole: Whole30, Keto, Paleo, GF Recipe has a special role in creating that perfect balance of flavor and texture. When shopping, look for fresh jalapeños and a good-quality buffalo sauce – I find these make a huge difference.

• Chicken breast: Use cooked and shredded chicken to save time, or cook fresh right before assembling.
• Frozen cauliflower rice: It’s a low-carb alternative to grains that absorbs the sauce wonderfully.
• Jalapeños: Freshly diced jalapeños add heat and freshness; adjust quantity for your spice tolerance.
• Onion: Adds a subtle sweetness and a bit of crunch.
• Red pepper: For color, sweetness, and a mild, crisp bite.
• Carrots: Finely diced for a touch of natural sweetness and texture.
• Coconut cream: The thick, creamy part adds richness and keeps this recipe dairy-free.
• Buffalo sauce: This packs the signature spicy tang that defines the dish.
• Ranch: Choose a Whole30-compliant or homemade ranch to keep things clean and creamy.
• Minced garlic: Provides a fragrant depth of flavor.
• Salt and black pepper: Essential seasoning to bring all the flavors together.
• Optional garnishes: Green onion and extra jalapeños for added freshness and punch.

Variations

I love that you can make this recipe your own in so many ways. Whether you want it spicier, creamier, or even packed with more veggies, this casserole adapts well to whatever you’re in the mood for.

• Spicy boost: I sometimes add smoked paprika or cayenne for an extra fiery kick that my spice-loving family adores.
• Dairy swap: If you’re not dairy-free, a sprinkle of shredded cheese on top before baking adds a lovely melty layer.
• Veggie swap: Swap the red pepper for zucchini or add mushrooms for a more earthy flavor.
• Protein change: Use shredded rotisserie chicken or even shredded turkey for a different twist.

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

Step 1: Prep your ingredients and preheat your oven

Start by preheating your oven to 400 degrees F. While it warms up, dice your jalapeños, onion, red pepper, and carrots. Make sure to finely dice the jalapeños so the heat distributes evenly—you don’t want big chunks sneaking up on you! If you haven’t cooked your chicken yet, this is a great time to pop it onto a sheet pan and bake it for about 25 minutes. I like to get everything chopped and ready while the chicken cooks—that’s my best trick for a smoother assembly phase.

Step 2: Combine veggies, chicken, and sauce

In your casserole dish, toss together the cooked, shredded chicken with all the diced veggies and frozen cauliflower rice. In a separate small bowl, whisk together minced garlic, coconut cream, buffalo sauce, ranch, salt, and pepper. This sauce is the magic that binds it all. Pour it evenly over the chicken and veggies, and use two forks or tongs to mix thoroughly. I like to distribute everything evenly so every bite is packed with flavor. Once mixed, smooth the casserole into an even layer—it helps it bake more evenly.

Step 3: Bake until bubbly and golden

Place the casserole in the oven for 45 minutes. You’re looking for the top to be slightly crispy and bubbling around the edges—that’s when you know it’s done. If you want a crispier top, leave it in a handful of extra minutes, but be careful not to dry it out. When I first made this, I almost impatiently pulled it too soon, so trust the timer for that perfect texture.

Step 4: Garnish and serve

Once out of the oven, drizzle a little more buffalo sauce or ranch on top, then sprinkle with green onions and extra jalapeños if you want to up the heat and freshness. This last step adds that pop of color and flavor that makes the dish feel extra special when you serve it.

Garnishes

I usually top mine with sliced green onions and a sprinkle of extra diced jalapeños for that fresh oniony crunch and a little heat surprise. Sometimes, a light drizzle of ranch right before serving cools everything down beautifully and adds that creamy pop I love.

Side Dishes

This casserole is a star on its own, but I like pairing it with a crisp side salad or some roasted broccoli to keep things fresh and balanced. A simple cucumber salad or even some garlic sautéed greens complement the spicy, creamy layers perfectly.

Creative Ways to Present

For a fun party, I’ve served this casserole in small individual ramekins topped with a jalapeño slice and a sprig of cilantro—instantly elevated! It’s also great scooped into lettuce cups as an interactive, low-carb option that guests love.

Make Ahead and Storage

Storing Leftovers

Leftovers keep beautifully in an airtight container in the fridge for up to 4 days. I like to portion it out for easy lunches, and it reheats nicely without losing flavor or texture.

Freezing

This Jalapeño Buffalo Chicken Casserole: Whole30, Keto, Paleo, GF Recipe freezes well, too. Just make sure to cool it completely before wrapping tightly in foil or placing in a freezer-safe container. It stays good for up to 3 months.

Reheating

To reheat, I recommend warming it in the oven at 350°F for about 15-20 minutes until heated through and lightly crisped on top. Microwaving works in a pinch but can make the casserole a bit soggy.
