Creating Loaded Baked Potato & Chicken Casserole is easy if you follow these steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Prepare Ingredients: In a large mixing bowl, combine the shredded chicken, cubed baked potatoes, sour cream, garlic powder, onion powder, salt, and pepper. Mix well until everything is combined.
3. Add Cheese and Bacon: Stir in half of the cheddar cheese, half of the mozzarella cheese, and the crumbled bacon. Make sure they are evenly distributed throughout the mixture.
4. Transfer to a Casserole Dish: Spread the mixture evenly in a greased 9×13-inch casserole dish.
5. Add Chicken Broth (Optional): If you want a creamier texture, pour the chicken broth over the mixture to provide extra moisture.
6. Top with Remaining Cheese: Sprinkle the remaining cheddar and mozzarella cheese evenly on top of the casserole.
7. Bake: Place the casserole in the preheated oven and bake for 45-50 minutes or until the cheese is bubbly and golden brown.
8. Let it Cool: Remove from the oven and let it cool for about 5-10 minutes.
9. Garnish: Before serving, sprinkle with chopped green onions for an extra touch of flavor and freshness.
