Making your Easy Low Carb Chicken Casserole is straightforward. Follow these simple steps:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).

5. Add Chicken: Fold in the shredded or diced chicken into the cheese mixture.
6. Combine with Vegetables: Add the sautéed vegetable mixture to the chicken and cream cheese blend. Stir to combine everything evenly.
7. Prepare Baking Dish: Grease a 9×13-inch baking dish and pour the combined mixture into it, spreading it out evenly.
8. Top with Cheese: Sprinkle the shredded cheddar cheese on top of the casserole.
9. Bake: Place in the preheated oven and bake for 35-40 minutes, or until the cheese is bubbly and slightly golden.
10. Serve: Once done, remove from the oven and let it cool for a few minutes before serving.
