Pour 4 pounds russet potatoes (peeled and diced), ½ white onion (finely diced), 1 can (10.5 oz) cream of chicken soup, 4 cups chicken broth, 1 teaspoon salt, and ½ teaspoon pepper into a crock pot.
Cover and cook on low for 5 hours.
Dice 1 package (8 oz) cream cheese into small cubes. Stir the cream cheese and ½ cup shredded cheddar cheese into the crock pot.
Cover and continue cooking on low for 20–30 minutes until the cheese is fully melted and incorporated.
Serve warm and top with additional cheese, bacon, and chives if desired.
Notes
You can use 1 30 oz bag of frozen diced hash browns instead of potatoes in this recipe if you prefer. Refrigerate any leftover soup in an airtight container for up to 5 days. The soup will thicken as it cools so you will want to add broth when reheating the soup to thin it back out.
