Recipe Notes

  • The red wine and parsley are optional, but add richness and depth of flavor.
  • Store leftover soup in an airtight container in the refrigerator. Reheat in the microwave or on the stovetop in a saucepot.
  • This soup freezes well – you may want to have some in reserve for a rainy (or snowy) day!

Here's how you make it:

  1. In a stock pot over medium heat, melt the butter and oil. Add the onions, garlic, bay leaves, thyme, and salt and pepper. Cook until the onions are deep brown and caramelized, 10 to 15 minutes.
  2. Add the wine (if using) and bring to a boil. Reduce heat and simmer until the wine has evaporated and the onions are dry, about 5 minutes. Remove the herbs.
  3. Dust the onions with the flour and stir. Reduce heat to medium low so the flour doesn’t burn and cook about 5 minutes. Add the beef broth slowly while stirring to avoid lumping. Return soup to a simmer. Season to taste with salt and pepper.
  4. Toast sliced baguettes until nicely brown. Rub each piece of toasted baguette with fresh cut garlic. Set aside.
  5. When ready to serve, preheat the oven to broil. Place the soup bowls in a roasting pan and ladle the soup into bowls. Top each bowl with 2 slices of bread and then a handful of grated Gruyere. Sprinkle fresh parsley on top, if desired. Place in the oven to toast the bread and melt the cheese. Serve.
