In a large slow cooker, combine hash browns, chicken broth, cream of chicken soup, cheddar cheese, green onions, pepper, and garlic powder.
Cover and cook on low for 6-8 hours or high for 3-4 hours, until the potatoes are tender.
About 30 minutes before serving, stir in the softened cream cheese and crumbled bacon.
Stir well until the cream cheese is fully melted and incorporated.
Ladle into bowls and top with extra green onions and bacon if desired.
