Ingredients

Pre-cooking your chicken and prepping all the fresh vegetables ahead of time makes assembling this casserole completely effortless.

• 2 pounds chicken breast, cooked and shredded: Provides a lean, protein-packed base that absorbs all the spicy buffalo and creamy sauce flavors.
• 20 ounces frozen cauliflower rice: Keeps the casserole low-carb and light while soaking up the rich pan juices and sauces.
• 2 small jalapeños, finely diced, plus more for topping if desired: Delivers a sharp, fiery kick that enhances the buffalo heat profile.
• 1 small white or yellow onion, diced: Adds a savory, sweet aromatic depth as it bakes into the casserole.
• 1 red pepper, diced: Brings a pop of vibrant color, crisp texture, and subtle natural sweetness to balance the heat.
• 1/2 cup shredded or finely diced carrots: Adds an essential subtle crunch and sweetness classic to buffalo wing pairings.
• 1/2 cup canned coconut cream (the thick part at the top of the can): Creates a luscious, dairy-free rich base without watering down the sauce.
• 1/2 cup buffalo sauce: Gives the dish its signature spicy, vinegary tang and vivid orange color.
• 1/4 cup ranch: Adds a cool, herb-infused tanginess that tempers the fiery jalapeño and buffalo elements.
• 1 tablespoon minced garlic: Infuses a sharp, punchy savory garlic flavor throughout the entire baked dish.
• 1 teaspoon salt: Draws out the natural flavors of the chicken and raw vegetables as they bake.
• 1/2 teaspoon black pepper: Brings a subtle background warmth to the spice blend.
• Optional: green onion, extra jalapeños to garnish: Adds a fresh, bright crunch and extra color right before serving.

Note: Serves 6 generous casserole portions based on these ingredient quantities.

Variations

You can easily tailor the heat level, dairy components, or vegetable bases to fit your household’s preferences.

• Dairy-Based Alternative: Swap the coconut cream for heavy cream, sour cream, or plain Greek yogurt if you eat dairy.
• Cheese Top Addition: Sprinkle a cup of shredded cheddar, pepper jack, or blue cheese crumbles over the top during the last 10 minutes of baking.
• Extra Veggie Boost: Toss in diced celery or spinach for even more texture and veggie content.
• Mild Heat Version: De-seed the jalapeños entirely or swap them for mild green chilies to keep the flavor without intense heat.

Cooking Time

Pre-baked or leftover chicken keeps the hands-on prep time ultra-fast before letting the oven do the work.

• Prep Time: 15 minutes
• Cooking Time: 45 minutes
• Total Time: 1 hour

Equipment you need

Using a large baking dish gives the ingredients plenty of space to bake evenly into a crispy casserole.

• Large Casserole Dish (9×13 inch): Essential for holding all the chicken, cauliflower rice, and fresh vegetables in a single even layer.
• Small Bowl & Fork: Used to whisk together the spices, garlic, coconut cream, buffalo sauce, and ranch into a smooth emulsion.
• Tongs or Two Forks: Perfect for tossing and distributing the liquid sauce thoroughly throughout the chicken and veggies.
• Chef’s Knife & Cutting Board: For finely dicing your onions, red peppers, carrots, and fresh jalapeños cleanly.

How to Make Jalapeño Buffalo Chicken Casserole?

Making this casserole is practically foolproof since you combine all your prepped ingredients directly in the baking dish before popping it in the oven.

Preheating and Prepping Vegetables

Preheat your oven to 400°F (200°C). Transfer the 20 ounces of frozen cauliflower rice, diced red pepper, diced onion, finely diced carrots, diced jalapeños, and 2 pounds of cooked shredded chicken into your large casserole dish.

Whisking the Creamy Buffalo Sauce

In a small bowl, add the 1/2 cup of thick coconut cream, 1/2 cup of buffalo sauce, 1/4 cup of ranch, 1 tablespoon of minced garlic, 1 teaspoon of salt, and 1/2 teaspoon of black pepper. Whisk vigorously with a fork until the mixture is completely smooth and combined.

Mixing and Smoothing the Casserole

Pour the buffalo mixture directly over the chicken and vegetables in the casserole dish. Use tongs or two forks to toss everything together, ensuring the sauce thoroughly coats every bit of chicken and cauliflower. Once fully incorporated, use the back of a spoon to smooth the ingredients into a single, compact, even layer.

Baking and Garnishing

Place the casserole dish into the preheated oven and bake for 45 minutes (or a few minutes longer if you prefer the top edges extra crispy and browned). Remove from the oven, let cool for a few minutes, then drizzle with extra ranch or buffalo sauce and top with chopped green onions and fresh sliced jalapeños before slicing.

Additional Tips for Making this Recipe Better:

A few simple tricks from my kitchen will ensure your casserole bakes up rich and thick rather than watery.

• I recommend using the solid cream portion from the top of a chilled can of full-fat coconut milk so your sauce stays nice and rich instead of runny.
• When I don’t have leftover chicken, I bake raw chicken breasts on a sheet pan at 400°F for 25 minutes while prepping my veggies, then shred them right into the casserole dish.
• I love switching the oven to broil for the final 2 to 3 minutes of cook time to give the top of the chicken and veggies a nice golden, bubbly crust.

How to Serve Jalapeño Buffalo Chicken Casserole?

Scoop big portions of the warm casserole into shallow dinner bowls using a sturdy spatula. Drizzle a fresh zigzag of cool ranch or blue cheese dressing across the top, followed by a sprinkle of sliced green onions, cilantro, and extra raw jalapeño rounds for those who want maximum heat. Serve it alongside a crisp side salad, celery and carrot sticks with dipping sauce, or warm garlic bread or tortilla chips for scooping up every bite!
