My grandson Casey likes what he calls french onion soup, but in reality is just onion soup. I came up with this recipe because he just wanted the basic soup with no frills. Now this has become a family staple. The trick is the caramelzation of the onions, long and slow which brings out the flavor. Hence the name Casey's French Onion Soup

How to Make Casey's French Onion Soup


  • 1Slice the onions thinly, the thinner the better.
  • 2Melt butter in a large pot, add onions.
  • 3Cook onions slowly over low heat, stirring often for 45 min. to an hour. The onions should be golden brown, and well caramelized and this takes time, don't hurry.
  • 4Stir in the sugar and flour, and cook for 3 - 4 min. You want to get rid of the flour taste
  • 5Add the beef broth ( I use the au jus base from GFS but any beef broth will do.
  • 6Add salt and pepper to taste.
  • 7This step is optional. I put soup into a 2 qt. crockpot (unless I double recipe then I use a 4 qt.) and let simmer on low for 3 - 4 hrs.
  • 8Ladle out soup into bowls and then top with cheese. I use torch and melt the cheese but you can also place under broiler but keep a watch on it or cheese melts to fast.
  • 9Soup can also be served without bread or cheese. Just as Casey likes it.
