This cheesy nacho soup combines all of those mouth watering nacho flavors that we love into an incredibly easy slow cooker soup! With only ten minutes of prep, and slow cooking to perfection, this soup is easy to love and will become a favorite to come home to after a busy day.
In a medium skillet over medium high heat, cook the ground beef until no longer pink, and drain grease if necessary.
Add the soups and beef broth to the slow cooker and stir or whisk to combine.
Add the beef, chopped onion, taco seasoning, and both cans of beans to the slow cooker and stir.
Cook on low for 6-8 hours or high for 3-4 hours.
OPTIONAL STEP FOR THICKER SOUP: 30 minutes before serving, combine the softened butter in a bowl with the flour. Stir this mixture into the soup to thicken.
