Ingredients
  

  • 4 yellow onions
  • 3 Tbsp unsalted butter
  • ¼ tsp sugar
  • ¼ cup white wine or dry vermouth or dry sherry
  • 6 cups chicken broth homemade if possible
  • 1 bay leaf
  • 2 tsp Worcestershire sauce
  • 3-4 sprigs fresh thyme or a pinch of dried
  • salt and pepper to taste
  • 8 slices baguette stale is fine
  • 1 clove garlic
  • 4-6 oz thinly sliced Swiss, Emmental or Gruyere cheese

Instructions
 

  • Remove outer skin from onions, slice in half and slice very thinly into half circles. Or slice carefully into rings.
  • Melt butter in a large stock pot over low heat and add onions. Toss to coat, put lid on pot and cook, checking every 10 minutes for 40-45 minutes until onions are soft and most of the liquid has evaporated.
  • Remove lid and continue to cook, stirring frequently until onions turn golden brown and begin to caramelize, being careful not to let them burn. About 45 to 60 minutes. Sprinkle sugar over onions toward end of this cooking stage to optimize caramelization.
  • Add white wine and cook over medium heat for a few minutes, stirring up the brown bits. Add chicken broth, bay leaf, Worcestershire sauce, thyme, salt and pepper. Simmer for 20-30 minutes on low.
  • Meanwhile, arrange baguette slices on a baking sheet. Toast in oven or in toaster until lightly browned. Remove from oven and rub garlic briskly over each piece while still warm. Slice cheese into wide thin pieces.
  • Preheat oven to 400 degrees on convection roast setting so heat is coming from the top.
  • Remove bay leaf and thyme sprigs from soup and ladle into 4 oven safe bowls. Top with two toasted baguette slices, pressing gently into the broth. Top with sliced cheese, arranging so top is covered and some hangs over the bowl edge.
  • Roast for about 10-15 minutes until cheese is melted and bubbling on top. Use broiler at the end if necessary to slightly brown the cheese.
  • Allow to cool slightly before serving.
