Rich and tasty cheeseburger soup. I use sharp Cheddar cheese because I like the taste but any Cheddar is good.
- 4 tablespoons butter, divided
- ½ pound ground beef
- ¾ cup chopped onion
- ¾ cup shredded carrots
- ¾ cup chopped celery
- 1 teaspoon dried basil
- 1 teaspoon dried parsley
- 4 cups cubed potatoes
- 3 cups chicken broth
- ¼ cup all-purpose flour
- 1 ½ cups milk
- 2 cups cubed Cheddar cheese
- ¼ cup sour cream
Melt 1 tablespoon butter in a large pot over medium heat; add ground beef, onion, carrots, and celery. Cook and stir until beef is browned and crumbly, 5 to 7 minutes.
Stir in basil and parsley. Add potatoes and broth and bring to a boil; reduce heat to low and simmer until potatoes are tender, 10 to12 minutes.
Melt remaining 3 tablespoons butter in a small saucepan over medium heat. Add flour and whisk until smooth, about 1 minute. Gradually whisk in milk; simmer and stir until sauce is thick and smooth.
Stir sauce into soup, stirring constantly. Bring to a boil; reduce heat to low and stir in cheese until melted. Add sour cream; stir until just heated through.
