Instructions

  1. 1

    Melt butter with olive oil in a large, heavy-bottomed Dutch oven over medium-low heat. Add sliced onions, sugar, and 1 teaspoon salt. Cook, stirring every 5–10 minutes, for 45–60 minutes until the onions are deeply caramelized to a rich mahogany color and reduced to a fraction of their original volume. If they stick, add a splash of water and scrape the bottom.

  2. 2

    Increase heat to medium-high, add the sherry, and cook until evaporated, scraping up all the caramelized bits. Add both broths, thyme, and bay leaves. Bring to a simmer and cook 20 minutes. Season with salt and pepper. Remove bay leaves.

  3. 3

    Preheat broiler to high. Ladle soup into oven-safe crocks or bowls. Float 2 slices of toasted baguette on top of each bowl. Mound a generous amount of the mixed grated cheeses over the bread, completely covering the surface.

  4. 4

    Place under the broiler 4 inches from heat for 3–5 minutes until the cheese is bubbling, browned, and slightly charred in spots. Serve immediately — the cheese will pull away in long strands as you dig through to the rich soup beneath.
