Step-by-Step Instructions

1. Preheat the Oven

Preheat your oven to 400°F (200°C) to ensure it’s hot and ready when you assemble the casserole.

2. Prepare the Chicken

If you don’t have pre-cooked chicken, bake 2 lbs of chicken breasts on a sheet pan at 400°F for 25 minutes while you prep the other ingredients. Once cooked, shred the chicken using two forks.

3. Chop the Vegetables

Dice the jalapeños, onion, red pepper, and carrots into small, even pieces for uniform cooking.

4. Combine Chicken & Veggies in a Casserole Dish

In a large casserole dish, mix together the shredded chicken, cauliflower rice, jalapeños, onion, red pepper, and carrots.

5. Make the Creamy Buffalo Sauce

In a small bowl, whisk together:

• Coconut cream

• Buffalo sauce

• Ranch dressing

• Minced garlic

• Salt & pepper

6. Mix Everything Together

Pour the sauce over the chicken and veggies, then use tongs or forks to evenly coat everything. Spread the mixture into an even layer.

7. Bake for 45 Minutes

Place the casserole in the oven and bake for 45 minutes (or longer if you prefer a crispier top).

8. Garnish & Serve

Once baked, drizzle with extra buffalo sauce or ranch, and top with green onions or more jalapeños for an extra kick!

 The Health Benefits of Jalapeño Buffalo Chicken Casserole

When it comes to comfort food, few dishes hit the spot like a creamy, spicy Jalapeño Buffalo Chicken Casserole. But what makes this dish truly special is that it’s not just delicious—it’s also packed with nutritional benefits that support a healthy lifestyle. Whether you’re following Whole30, keto, paleo, or gluten-free diets, this casserole is designed to fuel your body with high-quality ingredients.

High-Protein, Low-Carb Goodness

One of the biggest advantages of this casserole is its high protein content, thanks to the 2 pounds of chicken breast used in the recipe. Protein is essential for muscle repair, satiety, and metabolic health. Unlike carb-heavy casseroles that leave you sluggish, this dish provides long-lasting energy without the blood sugar spikes.

The cauliflower rice keeps the carb count low while adding fiber, making it perfect for keto and low-carb diets. With only 10.2g of carbs per serving, this dish helps maintain ketosis while still being filling.

Healthy Fats for Sustained Energy

The coconut cream in this recipe adds a rich, creamy texture while providing medium-chain triglycerides (MCTs)—a type of fat that’s easily converted into energy. Unlike unhealthy processed fats, MCTs support brain function and metabolism, making this casserole a great choice for anyone looking to stay sharp and energized.

Packed with Veggies for Extra Nutrients

This isn’t just a meat-and-sauce dish—it’s loaded with vegetables like:

• Jalapeños (rich in vitamin C and capsaicin, which boosts metabolism)

• Red peppers (high in antioxidants and vitamin A)

• Carrots (great for eye health and immune support)

• Onions and garlic (natural anti-inflammatory and immune-boosting properties)

By incorporating these veggies, you’re getting a well-rounded meal that supports digestion, immunity, and overall wellness.

Spicy Kick for Metabolism

Jalapeños and buffalo sauce don’t just add heat—they also boost metabolism! Capsaicin, the compound that makes peppers spicy, has been shown to:

• Increase fat burning

• Reduce appetite

• Improve circulation

If you’re looking for a meal that’s both flavorful and metabolism-boosting, this casserole delivers.
