Roasted Onion Trilogy Soup Lyonnaise

This thick Lyonnaise classic is prized as a late-night delight, and a hangover remedy, by onion-loving locals.

  • 1 medium leek, (washed cleaned, split in half lengthwise and cut into 1″ slices)
  • 2 pound brown skin onions, (thinly sliced (about 2 medium onions))
  • 2 pound white skin onions, (thinly sliced (about 2 medium onions))
  • 1 pound red skin onions, (thinly sliced (about 2 medium onions))
  • 6 cloves garlic, (unpeeled and left whole)
  • 3 tablespoons olive oil
  • Salt and black pepper, (to taste)
  • 1 tablespoon fresh thyme leaves, (chopped)
  • 1.5 cups red wine, (dry)
  • 4 cups white beef stock
  • 3 tablespoons fresh parsley, (chopped)
  • 16 slices French baguette, (1/4″ thick each)
  • 1 cup Gruyere cheese, (grated)
  1. Preheat the oven to 450°F/225°C.
  2. Toss leeks, onions, garlic, oil, salt, pepper, and thyme in a large roasting pan until well mixed. Place on a middle rack and roast for 30 minutes.

  3. Remove from the oven, add wine, and stir well. Roast another 10 minutes.

  4. Remove from the oven and transfer onions to a large pot. Pour 1/2 cup stock in the roasting pan to scrape up any bits clinging to the bottom. Add this and remaining stock to the pot with onions and 4 cups of hot water.

  5. Simmer soup, partially covered, for 30 minutes. Taste for seasoning.
  6. Meanwhile, preheat broiler. Place baguette slices on a baking sheet. Broil 1 minute or until just barely toasted. Remove and flip slices over. Sprinkle two teaspoons grated cheese on top of each slice and broil another 1 to 2 minutes, or until cheese is melted and bubbling. Remove from the oven and keep in a cool, dry place until ready to serve.

  7. Serve hot, each bowl topped with 2 cheese croutons on top and a sprinkling of chopped parsley.
