Ingredients You’ll Need

The ingredients in this recipe create a balanced mix of spice, creaminess, and texture. I like buying fresh jalapeños and coconut cream from reliable sources to get the best flavor and consistency.

• Chicken breast: Use cooked and shredded—roasting them yourself is quick and adds great texture.
• Frozen cauliflower rice: A fantastic low-carb base that soaks up all the flavors.
• Jalapeños: Fresh and diced finely for that perfect kick, add more if you like it hotter.
• Onion (white or yellow): Adds sweetness and depth to balance the spice.
• Red pepper: Adds color and a mild sweetness to the casserole.
• Carrots: Finely diced for slight natural sweetness and crunch.
• Canned coconut cream: The thick top part—this is the secret to creamy, dairy-free richness.
• Buffalo sauce: Use your favorite Whole30-approved brand or homemade for that signature buffalo flavor.
• Ranch: Adds tang; use Whole30-friendly ranch for the healthiest choice.
• Minced garlic: A small touch but it rounds out the flavor beautifully.
• Salt and black pepper: Season to taste to bring everything together.
• Optional garnishes: Green onion or extra jalapeños add freshness and flair on top.

Variations

I love experimenting with this casserole by swapping out a few ingredients or adjusting the heat to suit my mood. Feel free to make it your own by trying different add-ins or tweaking the sauce level!

• Milder Version: If you’re sensitive to spice, reduce the jalapeños and use a milder buffalo sauce—I’ve done this for family dinners and everyone still loved it!
• Extra Veggies: I sometimes toss in mushrooms or zucchini for extra texture and nutrition, which works wonderfully without overpowering the dish.
• Dairy-Free Ranch Alternative: Using a homemade cashew-based ranch keeps it Whole30 and adds creaminess without dairy.
• Make It Spicier: For heat lovers like me, adding a pinch of cayenne or more fresh jalapeños really elevates the flavor.

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

Step 1: Prep Your Chicken and Veggies

If you don’t have cooked chicken ready, I recommend baking your chicken breasts at 400°F for about 25 minutes while you chop all your vegetables. This multitasking saves so much time. Once the chicken is cool enough to handle, shred it finely with two forks—shredded chicken mixes into the casserole more evenly and keeps every bite tasty.

Step 2: Combine Ingredients in Your Casserole Dish

Grab a large casserole dish and layer in your frozen cauliflower rice, shredded chicken, diced jalapeños, onion, red pepper, and carrots. Stir everything together lightly so the distribution feels even—this means every slice of casserole has balanced flavors.

Step 3: Whisk Together the Sauce

In a small bowl, mix minced garlic, salt, black pepper, buffalo sauce, ranch, and the thick coconut cream. Whisk with a fork until smooth and creamy. This sauce is the magic that brings creamy heat and richness to the whole dish.

Step 4: Pour Sauce and Bake

Pour the sauce over the casserole ingredients and gently use two forks or tongs to toss everything together until coated. Then, smooth it out into an even layer in the dish so it cooks evenly. Pop it into a preheated 400°F oven and bake for 45 minutes. If you like a slightly crispy top, give it a few extra minutes—that’s how I usually do it!

Step 5: Garnish and Serve

Once out of the oven, I love to add another drizzle of buffalo or ranch sauce and sprinkle chopped green onions or extra jalapeños on top for a fresh, pretty finish. This step is optional but really takes the dish over the top.

Garnishes

I always top my servings with fresh chopped green onions and an extra sprinkle of diced jalapeños for a little crunch and heat. Sometimes, a small drizzle of extra ranch or buffalo sauce adds that finishing touch that makes every bite delicious.

Side Dishes

This casserole shines with simple, fresh sides like a crisp green salad or roasted Brussels sprouts. When I want to keep it low-carb, I serve steamed broccoli or sautéed kale. These sides complement the spicy, creamy flavors perfectly without competing.

Creative Ways to Present

For special occasions, I’ve served this casserole in individual ramekins, topped with a swirl of ranch and a jalapeño ring for a pretty presentation. You could also turn it into a layered dip by scooping it into an oven-safe dish and serving alongside celery sticks and keto crackers—always a crowd-pleaser!

Make Ahead and Storage

Storing Leftovers

Leftovers store beautifully in an airtight container in the fridge for up to 4 days. When I’ve made extra, I just cover the dish tightly and reheat portions during the week—easy and tasty lunches or dinners without extra work.

Freezing

I like freezing this casserole in single-serve containers for quick meals. It freezes well, though I suggest slightly underbaking before freezing to avoid sogginess. Then, freeze it and thaw overnight when ready to enjoy.

Reheating

Reheat leftovers in the oven at 350°F for about 15-20 minutes to revive that baked texture and crispy edges. The microwave works in a pinch, but I prefer oven reheating for the best flavor and consistency.
