In a large bowl, combine the shredded chicken, frozen hash browns, ranch dressing, cheddar cheese, sour cream, green onions, garlic powder, onion powder, salt, and pepper. Mix well until all ingredients are fully incorporated.
Grease a 9x13 inch casserole dish with non-stick spray and pour the mixture into the dish, spreading it evenly.
Sprinkle the top with the crispy bacon bits, ensuring an even layer is formed over the entire casserole.
Cover the dish with aluminum foil and bake in the preheated oven for 30 minutes.
After 30 minutes, remove the foil and bake for an additional 15-20 minutes, or until the top is golden and bubbly.
Once cooked, remove from the oven and let it cool for a few minutes before serving.
Garnish with extra green onions and chopped parsley for a fresh touch.
Notes
Feel free to add more toppings like cheese or jalapeños for extra flavor.
