  • Heat the olive oil in a large, heavy-bottomed pot over medium heat.
  • Halve, peel, and slice the onions thinly, then add them to the pot and stir.
  • Add the brown sugar and Worcestershire sauce, and continue to cook, stirring every few minutes, until the onions become a deep golden brown.
  • Stir in the garlic, cooking until fragrant.
  • Add the butter to the pot, sprinkle in the flour, and stir everything together.
  • Pour in the wine and stir, scraping any browned bits from the bottom of the pot with your spoon.
  • Stir in the stock, add the herbs, and allow the soup to come to a simmer.
  • Season with salt and pepper.
  • Remove the thyme stems and bay leaf, then ladle the soup into heat-safe bowls or crocks, and top with toasted bread and cheese.
  • Melt the cheese under the broiler, until browned and bubbly, and serve.



*I like to use a sweet onion variety such as Maui or Vidalia, but you can use any kind of onion you prefer.
