Preparation Phase & Tools to Use

Getting everything prepped is key to making this dish smooth and fuss-free. Here’s what you’ll need to have on hand:

• Casserole Dish (9×13 inches): This is where the magic happens. A sturdy, oven-safe casserole dish ensures even baking and a crispy top layer.
• Nonstick Skillet: You’ll need this to cook your chicken and sauté the aromatics without sticking.
• Mixing Bowls: A couple of medium-sized bowls help you mix your sauce and combine ingredients with ease.
• Wooden Spoon or Silicone Spatula: For folding all the components together gently without breaking them apart.
• Measuring Cups and Spoons: Precise measurements are important, especially with creamy sauces where too much or too little can affect texture.

Organizing these tools ahead of time sets you up for a seamless cooking experience. Trust me, this little bit of planning makes all the difference!

Ingredients for the Low Carb Chicken Casserole

Each ingredient plays a crucial role in building flavor, texture, and keeping it low in carbs:

• Cooked Chicken (shredded or diced): The star of the dish, providing protein and heartiness.
• Cream Cheese: Adds a rich, creamy base to the sauce while keeping carbs minimal.
• Sour Cream: Brings a tangy balance that keeps the sauce from being overly heavy.
• Shredded Cheddar Cheese: Melts beautifully on top and throughout the casserole for that gooey factor.
• Garlic Powder & Onion Powder: Essential flavor boosters without the added carbs of fresh garlic or onions.
• Diced Green Chiles (optional): For a bit of mild heat and a Tex-Mex twist.
• Steamed Cauliflower Florets: A brilliant low-carb swap for pasta or rice that soaks up the sauce.
• Salt & Pepper: To taste, enhancing every bite.
• Fresh Parsley (optional): For a pop of color and freshness when serving.

How To Make the Low Carb Chicken Casserole

Step 1: Preheat & Prep

Preheat your oven to 375°F (190°C). Lightly grease your 9×13 casserole dish to prevent sticking.

Step 2: Mix the Creamy Base

In a mixing bowl, combine the cream cheese, sour cream, garlic powder, onion powder, and a pinch of salt and pepper. Stir until smooth and fully blended.

Step 3: Fold in the Filling

Add the shredded chicken, steamed cauliflower, and green chiles (if using) into the creamy mixture. Gently fold everything together until coated.

Step 4: Assemble in the Dish

Spread the mixture evenly into the prepared casserole dish. Sprinkle shredded cheddar cheese generously over the top.

Step 5: Bake to Perfection

Bake uncovered for 20-25 minutes, or until the casserole is hot and the cheese is bubbly and golden.

Step 6: Garnish and Serve

Remove from oven and let it cool for a few minutes. Sprinkle with chopped fresh parsley before serving if desired.

How to Serve and Store This Low Carb Chicken Casserole

This casserole is best served hot and fresh from the oven when the cheese is bubbling and golden. Pair it with a crisp side salad, roasted green beans, or steamed asparagus for a full low-carb dinner. For brunch or a cozy lunch, it’s filling enough to stand alone!

If you have leftovers, let the casserole cool completely before transferring to an airtight container. Store in the refrigerator for up to 4 days. To reheat, simply microwave individual portions or bake at 350°F until warmed through. It also freezes well—wrap tightly and freeze for up to 2 months. Thaw in the fridge overnight before reheating.

Frequently Asked Questions

How can I make this casserole spicier?

You can stir in diced jalapeños, use pepper jack cheese, or add a dash of hot sauce to the creamy base for an extra kick.

Can I use rotisserie chicken?

Absolutely! Using pre-cooked rotisserie chicken saves time and adds extra flavor. Just be sure to remove any skin and bones.

What can I substitute for cauliflower?

Broccoli florets work well as a low-carb swap. Zucchini slices can also be used but may release more water, so reduce liquid slightly.

Is this casserole keto-friendly?

Yes! It’s loaded with fat from cheese and cream, and very low in carbs, making it ideal for keto eaters.

Can I add vegetables to the mix?

Sure! Try spinach, mushrooms, or bell peppers for added nutrients and flavor. Just sauté them first to avoid excess moisture.

How do I keep it from becoming watery?

Make sure your cauliflower is well-drained and pat it dry before mixing in. This helps prevent excess moisture from thinning out the sauce.
