Combine the Soup Base: Add the frozen hashbrowns, diced onion, chicken broth, cream of chicken soup, and butter to a large pot over medium heat. Stir occasionally until the butter has completely melted.
32 oz frozen diced hashbrown potatoes, 1 small yellow onion, 2 14.5 oz cans reduced-sodium chicken broth, 1 10.5 oz can condensed cream of chicken soup, 6 tablespoons salted butter
Cook the Potatoes: Bring the soup to a gentle simmer and cook for 20 minutes, stirring occasionally to prevent sticking. The hashbrowns should be tender and easily pierced with a fork.
Make It Creamy: Reduce the heat to low. Stir in 1 ½ cups shredded cheddar cheese, 1 cup sour cream, kosher salt, and black pepper. Stir gently until the cheese has melted and the soup is smooth and creamy.
1 ½ cups shredded medium cheddar cheese, 1 cup sour cream, ½ teaspoon kosher salt, ¼ teaspoon ground black pepper
Add the Loaded Toppings: Divide the soup among bowls. Top each serving with crumbled bacon, extra shredded cheddar, sliced green onions, and a spoonful of sour cream.
6 slices bacon, ½ cup shredded cheddar cheese, ¼ cup sliced green onions, ½ cup sour cream
Serve: Serve immediately while the soup is hot and the cheese is melted.
