Step-by-Step Instructions for Low Carb Chicken Casserole

Making this Low Carb Chicken Casserole is as simple as layering, mixing, and baking. Let’s get started:

1. Preheat the Oven

Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.

2. Prepare the Base

Spread the cooked cauliflower rice evenly across the bottom of your prepared baking dish. This will act as the “grain-free” base for your casserole.

3. Steam the Veggies

Steam the broccoli florets until tender but still bright green. Drain well and layer them over the cauliflower rice.

4. Mix the Sauce

In a medium bowl, whisk together the cream cheese, sour cream, heavy cream, garlic powder, onion powder, smoked paprika, salt, and pepper until smooth and creamy.

5. Add the Chicken

Stir the shredded chicken into the sauce until evenly coated, then spread this mixture over the broccoli layer in your baking dish.

6. Top with Cheese

Sprinkle shredded cheddar cheese evenly over the top. For extra flavor, you can add a little grated Parmesan as well.

7. Bake and Serve

Bake uncovered for 25–30 minutes, or until the casserole is bubbly and the cheese is golden brown. Let it cool for a few minutes before serving.
