Creating the Creamy Low Carb Chicken Casserole is easy when you follow these steps:

1. Preheat the Oven: Start by preheating your oven to 375°F (190°C).

2. Sauté the Vegetables: In a medium pan, heat olive oil over medium heat. Add broccoli, cauliflower, and bell peppers. Sauté for about 5-7 minutes until they are tender but still crisp. Remove from heat.

3. Prepare the Casserole Mixture: In a large bowl, combine cream cheese, sour cream, chicken broth, garlic powder, onion powder, Italian seasoning (if using), salt, and pepper. Mix well until smooth.

4. Add Chicken and Vegetables: Stir in the shredded chicken and sautéed vegetables into the creamy mixture until everything is well coated.

5. Transfer to Baking Dish: Pour the mixture into a greased 9×13 inch baking dish, spreading it evenly.

6. Top with Cheese: Sprinkle shredded cheddar cheese generously on top of the casserole.

7. Bake: Place the casserole in the preheated oven and bake for 30-35 minutes, or until the cheese is bubbly and slightly golden.

8. Cool and Serve: Once baked, allow cooling for about 5 minutes before serving to set the casserole slightly.

These simple steps will guide you to create a mouth-watering Creamy Low Carb Chicken Casserole everyone will enjoy!
