Ingredients

  • 3 large onions - or about 2 lbs of onions I like to use a mixture of onions
  • 3 tbs butter
  • 1 teaspoon sugar
  • 2 sprigs fresh thyme
  • ½ teaspoon oregano leaves
  • 1 bay leaf
  • ½ cup cooking Sherry
  • 2 quarts of veg or beef broth
  • 2-3 large garlic cloves minced
  • 1 baguette sliced crosswise
  • 1 lb swiss cheese

Instructions

  • Slice onions thin.
  • In a large stock pot or dutch oven place all onions on med-heat and allow to sweat for a few minutes.
  • Add sugar. (Sugar helps quicken the caramelizing process of the onions)
  • Continue stirring and browning the onions. Adjust the heat if they are scorching or not cooking.
  • After about 10 minutes add butter, minced garlic and herbs.
  • When the onions are a deep golden brown (about 20-25 minutes of cooking) turn the heat up. Stiring constantly-add sherry. Continue stirring on high to med-high heat for about 5 minutes. The sherry will thicken and the alcohol will be dry.
  • Add broth and let soup simmer for at least 30 minutes up to a couple of hours.
  • Under broiler toast baguette slices till golden brown and nice and dry.
  • Shred cheese.
  • In an oven-proof individual sized soup bowl or mug ladle in soup. Top with baguette and a handful of cheese. Place soups on a foil lined sheet cake pan and broil until cheese is melted.
  • Serve immediately.
