What to Serve with Beef Mushroom Soup

With beef, vegetables, and noodles, this soup is a full meal on its own. We recommend keeping things simple and serving it with some crusty bread, garlic bread, or breadsticks.

💭 Tips

  • Mix your sour cream into the soup about 10 minutes before you’re ready to serve. This allows it to thicken the soup without the noodles cooking for too long.
  • It’s important not to overcook your egg noodles. They will get gummy and soft.
  • We recommend low-sodium beef stock because the onion soup mix and Worcestershire sauce both have quite a bit of salt in them.
