Ingredient Substitutions & Tips

• Cooked chicken: Use rotisserie chicken for convenience or shredded turkey for a different flavor profile.
• Cauliflower rice: Substitute with finely chopped cabbage or riced broccoli if you want to mix up the veggies.

How to Make Easy Whole30 Jalapeño Buffalo Chicken Casserole Recipe

Step 1: Preheat and prepare your ingredients

Set your oven to 375°F (190°C) and gather all ingredients. This little prep sets the stage, ensuring your cooking flows easily without rushing.

💡 Pro Tip: While the oven warms up, chop vegetables and shred the chicken to save time.

Step 2: Sauté onions and garlic

Heat a large skillet on medium heat and add diced onion and minced garlic. Cook, stirring occasionally, until the onion turns soft and translucent, releasing a sweet fragrance that signals it’s time for the next step.

💡 Pro Tip: Don’t rush this step; gentle cooking here builds a richer flavor base.

Step 3: Combine chicken, veggies, and buffalo sauce

Add your shredded chicken, cauliflower rice, diced jalapeños, and broccoli florets into the skillet. Pour in the Whole30-compliant buffalo sauce, then stir everything until the buffalo goodness evenly coats each ingredient.

💡 Pro Tip: Taste a bit here to decide if you want more heat or buffalo sauce—feel free to tweak.

Step 4: Mix in coconut milk and season

Pour the full-fat coconut milk into the skillet, stirring gently until the sauce is silky and uniformly mixed. Season with salt and pepper according to your taste preferences, enhancing the layers of flavor beautifully.

💡 Pro Tip: Use a pinch of salt first; you can always add more later after baking.

Step 5: Transfer to baking dish and bake

Grease a 9×13-inch baking dish lightly, then pour the savory mixture into it, spreading evenly. Slide it into your preheated oven and bake for 25 to 30 minutes, letting the casserole bubble and the broccoli soften perfectly.

💡 Pro Tip: Bake uncovered to get that lovely bubbling top, signaling it’s done.

Step 6: Cool and garnish

Remove the casserole from the oven and allow it to cool for a few minutes—you’ll want it warm, but not scorching hot. Sprinkle fresh cilantro on top if you’re using it; the fresh herbaceous note adds contrast and brightness.

💡 Pro Tip: Cooling slightly helps the casserole set for cleaner serving portions.

Common Mistakes to Avoid

Learn from these common pitfalls:

• Overcooking broccoli: It turns mushy and dulls the flavor; aim for tender-crisp.
• Skipping the sauté step: Raw onion flavor can be harsh and overpowering.
• Using low-fat coconut milk: Results in a thinner sauce lacking creamy richness.
• Ignoring seasoning: Salt and pepper bring all the flavors together—don’t forget them!
• Adding too many jalapeños: The heat can become overwhelming; start mild and adjust.
• Serving piping hot: It’s difficult to serve and flavors have not fully blended.

Delicious Variations to Try

Once you’ve mastered this classic casserole, shake things up with these tasty variations:

Cheesy Whole30 Boost

Add a sprinkle of nutritional yeast before baking for a vegan “cheesy” flavor that deepens the dish without dairy.

Sweet and Spicy Twist

Veggie Lover’s Edition

Load up with mushrooms, zucchini, or bell peppers for an extra colorful and nutrient-rich casserole.

Smoky Chipotle Kick

Replace jalapeños with chipotle peppers in adobo sauce for a smoky, deep heat that’s incredibly flavorful.

Herbed Freshness

Finely chop fresh basil or parsley to sprinkle on top after baking for a delightful herbal burst.
