Instructions Checklist
  • Melt butter and olive oil in a large Dutch oven or heavy pot over medium heat. Add onions. Spread them out in as thin a layer as possible. Sprinkle with sugar, and cook, stirring as needed to keep onions from sticking, until they are melting and soft, golden brown, and beginning to caramelize, about 1 hour.

  • Sprinkle flour over onions, and stir to coat. Add sherry, stock, and thyme, and bring to a simmer. Cook, partially covered, for about 30 minutes, to allow the flavors to combine. Season with salt and pepper to taste.

  • Meanwhile, preheat broiler. Arrange bread on a rimmed baking sheet and broil until deep-golden brown on both sides, about 1 to 2 minutes per side; set aside.

  • Ladle 1 cup hot soup into four 13-ounce ramekins or ovenproof bowls. Arrange the bowls on a rimmed baked sheet. Place 2 slices of toasted bread over each bowl of soup to cover the surface of the soup completely. Sprinkle 3 ounces grated cheese over bread in each bowl, and place under broiler until cheese is melted and crusty brown around the edges. Watch carefully that bread doesn't burn. Serve immediately.

I have made this several times over the past year or two. The only adjustment is that I did not add the sugar. I can't eat processed sugar and my husband doesn't need it, but we also don't want it sweet, so we don't even use Stevia. The onions caramelize anyway, and cooking them for 45 mins to an hour works great. Always turns out excellent! Following the recipe (without sugar), always turns out exceptional!We just love the taste

Made soup a moment ago. Ago with most that adding the sugar did make it a bit sweet. Next time I will avoid adding the sugar and sprinkle the onions with a small amount of salt to draw out the natural sugar in the onions while they are cooking down.
