Creating Crack Chicken Casserole is simple and enjoyable. Follow these steps for a delicious outcome:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).
2. Prepare Your Chicken: In a large mixing bowl, combine the shredded chicken, cream cheese, and ranch dressing. Blend until well incorporated.
3. Add Seasonings: Sprinkle in the garlic powder, onion powder, salt, and black pepper. Stir until evenly mixed.
4. Combine Ingredients: Fold in the cream of chicken soup, shredded cheddar cheese, cooked bacon, and green onions, if using.
5. Incorporate Rice: Add the cooked rice (or pasta) into the mixture and stir until everything is well combined.
6. Transfer to Baking Dish: Pour the mixture into a greased 9×13-inch baking dish, spreading it evenly.
7. Add Topping (Optional): If you desire a crispy topping, sprinkle breadcrumbs over the casserole.
8. Bake: Place the dish in the preheated oven and bake for 30-35 minutes, or until bubbly and golden on top.
9. Cool Before Serving: Take the casserole out of the oven and let it cool for about 5-10 minutes before serving. This helps it set.
