I developed this recipe when I once had an abundance of sweet onions. I like making it for guests, but sometimes I'll halve the recipe and make some just for me! —Sharon Berthelote, Sunburst, Montana

Ingredients

  • 2 cups thinly sliced onions
  • 1/2 cup butter, cubed
  • 1/4 cup all-purpose flour
  • 2 cups chicken broth
  • 2 cups 2% milk
  • 1-1/2 to 2 cups shredded part-skim mozzarella cheese
  • Salt and pepper to taste
  • Croutons, optional

Directions

  1. In a large saucepan, cook onions in butter over low heat until tender and transparent, about 20 minutes.
  2. Stir in flour. Gradually add broth and milk; cook and stir over medium heat until bubbly. Cook and stir for 1 minute longer; reduce heat to low. Add mozzarella cheese and stir constantly until melted (do not boil). Season to taste with salt and pepper. Serve with croutons if desired.
