Broccoli Florets (1 ½ cups, lightly steamed) – Adds fiber, vitamins, and a fresh flavor that balances the creaminess.

Cream Cheese (8 oz, softened) – Creates a rich, velvety texture that ties the dish together.
Sour Cream (½ cup) – Adds tanginess for flavor depth.

Cheddar Cheese (1 cup, shredded) – Melts beautifully for that gooey, cheesy topping.

Step-by-Step Instructions

1. Prepare the Oven and Baking Dish

Preheat your oven to 375°F (190°C). Grease a medium-sized baking dish with butter or non-stick spray to prevent sticking.

2. Steam the Vegetables

Lightly steam broccoli and cauliflower until just tender. This ensures they maintain texture after baking rather than becoming mushy.

3. Make the Creamy Base

In a large bowl, combine cream cheese, sour cream, heavy cream, garlic powder, paprika, salt, and pepper. Mix until smooth and fully blended.

4. Combine the Ingredients

Add shredded chicken, broccoli, and cauliflower to the creamy mixture. Stir until every piece is well coated.

5. Assemble the Casserole

Transfer the mixture into your prepared baking dish. Spread evenly, then sprinkle cheddar cheese and Parmesan cheese on top.

6. Bake to Perfection

Place in the oven for 25–30 minutes, until hot and bubbly with a golden-brown top.

7. Serve and Enjoy

Let it rest for 5 minutes before serving. This makes slicing easier and allows the flavors to settle.

Pro Tips for the Best Creamy Low Carb Chicken Casserole

Use freshly shredded cheese – Pre-shredded varieties often contain anti-caking agents that affect melting.
Don’t overcook vegetables – They should be tender-crisp before baking.
Add a crunchy topping – Sprinkle crushed pork rinds or almond flour mixed with Parmesan before baking for extra texture.
Make it ahead – Prepare the casserole up to the baking step, refrigerate, then bake when ready to serve.

Tasty Variations

While this recipe is already delicious, you can customize it to fit your taste preferences or what’s in your fridge:

Protein Swap – Use turkey, ground beef, or even rotisserie chicken.
Extra Veggies – Add spinach, zucchini, or bell peppers for more color and nutrients.
Spicy Kick – Mix in diced jalapeños, chili flakes, or cayenne pepper.
Herb Boost – Fresh parsley, thyme, or basil can brighten the flavors.

Serving Suggestions

Storage & Reheating

Refrigerator – Store in an airtight container for up to 4 days.
Freezer – Freeze portions for up to 3 months. Thaw overnight in the fridge before reheating.

Common Mistakes to Avoid

Using watery vegetables – Make sure broccoli and cauliflower are drained after steaming.
