Slow cooker cheeseburger soup, originally from Taste of Home, is a rich and creamy, cheesy soup made with ground beef, potatoes, onions, and carrots in a Velveeta base with a mildly spicy kick. This soup is a huge hit and makes enough for a crowd.
Brown the ground beef in a large skillet over medium-high heat; remove cooked beef from pan, drain, and add to slow cooker.
Add onion, carrots, celery, basil, parsley flakes, broth, and potatoes into the slow cooker. Press garlic into crock.
Cook soup on low for 6-8 hours or on high for 3-4 hours, or until potatoes and veggies are tender.
About an hour before you intend to serve the cheeseburger soup, make a roux in a small skillet by melting 3 tablespoons butter. Add flour; cook and stir for 3-5 minutes or until bubbly. Add salt, pepper, milk, and cream cheese and mix well.
Add roux to soup. Add roux and cheese to the soup. Turn slow cooker to high and cook for an additional 30 minutes, stirring a few times until the cheese melts.
