Step-by-Step Instructions
1. Cook the Bacon and Onion
In a large skillet, cook the bacon over medium heat for 6 to 7 minutes, until crisp. Drain on paper towels, crumble, and set aside. Reserve 2 tablespoons of the drippings in the skillet. Add the chopped onion to the drippings and cook until softened, about 6 minutes.
2. Simmer the Potatoes
In a large Dutch oven or stockpot, combine the onion, chicken broth, and cubed potatoes. Bring to a boil, then reduce the heat and simmer for about 10 minutes, or until the potatoes are tender enough to mash with a fork.
3. Make the Roux
In the same skillet used for the bacon, melt the butter over low heat. Stir in the flour with a whisk until smooth. Cook for 1 minute, stirring constantly. Slowly whisk in 2 cups of milk until blended and smooth.
4. Build the Soup Base
Pour the milk mixture into the pot with the potatoes and broth. Add the remaining 2 cups of milk, along with the salt and pepper. Cook over medium heat, stirring frequently, until the soup thickens and bubbles.
5. Add the Fillings
Stir in the diced ham, half the bacon, the sour cream, 2 cups of Cheddar cheese, and ½ cup of green onions. Cook gently until the cheese melts and the soup is heated through.
6. Serve with Toppings
Ladle the soup into bowls and garnish each serving with the remaining bacon, cheese, and green onions. Serve hot, with a slice of crusty bread or a side salad for a complete meal.
