Instructions

  1. 1

    Slice the yellow onions thinly.

  2. 2

    In a large heavy-bottomed pot or Dutch oven, melt the butter with olive oil over medium heat. Add the sliced onions and cook, stirring occasionally, until deeply caramelized and tender, about 45-60 minutes. Add minced garlic during the last 5 minutes of caramelization.

  3. 3

    Pour in the dry sherry and scrape up any browned bits from the bottom of the pot. Let it simmer for 2 minutes.

  4. 4

    Add the beef broth, thyme sprigs, and bay leaf. Season with salt and black pepper. Bring to a boil, then reduce heat and simmer for at least 20 minutes, allowing flavors to meld.

  5. 5

    While the soup simmers, toast the baguette slices until lightly golden.

  6. 6

    Remove thyme sprigs and bay leaf from the soup. Ladle the soup into oven-safe bowls. Top each bowl with a toasted baguette slice and generously sprinkle with shredded Gruyère cheese.

  7. 7

    Broil for 2-3 minutes, or until the cheese is melted and bubbly and lightly browned.
