The cooking process explained
Let me walk you through how this delightful casserole comes together. First, you’ll combine cooked chicken with broccoli and optional cauliflower rice, forming a tasty base.

Finally, assemble it all in a baking dish, top it off with more cheese, and let the oven work its magic! It truly is that simple.
Gather these items
To make this Easy Low Carb Chicken Casserole, you will need the following ingredients:
- 3 cups cooked chicken, shredded or diced (rotisserie chicken works well)
- 2 cups broccoli florets, steamed
- 1 cup cauliflower rice (optional, for added volume)
- 1½ cups shredded cheddar cheese
- 1 cup shredded mozzarella cheese
- 1 cup heavy cream
- ½ cup sour cream
- 4 oz cream cheese, softened
- 1 tsp garlic powder
- 1 tsp onion powder
- ½ tsp smoked paprika
- Salt and black pepper to taste
- ½ cup grated Parmesan cheese (optional, for topping)
Feel free to mix things up! You could substitute veggies based on your preference or dietary requirements.
Directions to follow

Preheat Oven: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with cooking spray or butter.
Prepare the Base: In a large bowl, combine the cooked chicken, steamed broccoli, and cauliflower rice (if using).
Make the Sauce: In a medium saucepan over medium heat, whisk together heavy cream, sour cream, and cream cheese until smooth. Stir in garlic powder, onion powder, smoked paprika, salt, and black pepper. Remove from heat and mix in 1 cup of cheddar cheese until melted.
Assemble the Casserole: Pour the cheese sauce over the chicken and vegetable mixture, tossing to coat evenly. Transfer to the prepared baking dish.
Add Cheese Topping: Sprinkle the mozzarella cheese, remaining cheddar cheese, and Parmesan cheese evenly over the top.
Bake: Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbling and the top is golden brown.
Serve: Remove from the oven and let rest for 5 minutes before serving.
Best ways to enjoy it
To elevate your dining experience, serve this casserole with a fresh side salad dressed in a light vinaigrette. The coolness of the salad perfectly contrasts the warm, cheesy casserole. You can also pair it with roasted vegetables or a side of garlic bread if you’re not strictly monitoring carbs.

This casserole is perfect for leftovers! Store any unused portions in an airtight container in the refrigerator for up to 3-4 days. Reheat individual servings in the microwave or in the oven at 350°F (175°C) until warmed through. If you want to store it longer, consider freezing: wrap it tightly in plastic wrap and then foil for up to 2-3 months. Just remember, safety first: always cool your dish before freezing!
