Potato Soup with Sour Cream

Set aside 4 potatoes; peel and cube the remaining potatoes.

Place cubed and whole potatoes into a large pot and cover with salted water; bring to a boil. Reduce heat to medium-low and simmer until soft, about 20 minutes. Drain. Set the 4 whole potatoes aside; mash the rest.

At the same time, place bacon in a large skillet and cook over medium-high heat, turning occasionally, until evenly browned, about 10 minutes. Drain bacon slices on paper towels. Crumble and set aside. Cut reserved whole potatoes into small cubes and set aside with bacon.

Heat flour in a large saucepan or pot over medium heat; slowly add milk, whisking until well blended. Add salt and pepper. Bring to a boil, stirring frequently, and cook for 8 to 10 minutes. Add mashed potatoes and stir well to combined. Remove soup from heat. Stir in 1 cup Cheddar cheese and mix until it melts completely. Stir in sour cream. Taste and adjust salt.

Serve warm topped with bacon, cubed potatoes, remaining Cheddar cheese, and green onions.
