Method

Preparation

  1. 1

    Slice the Onions

    Peel and thinly slice the yellow onions. Aim for uniform slices for even cooking.

  2. 2

    Prep the Sourdough

    Butter one side of each slice of sourdough bread and set aside for later.

Cooking the Soup

  1. 3

    Sauté the Onions

    In a large pot, heat the olive oil over medium heat. Add the sliced onions and a pinch of salt. Cook slowly, stirring occasionally, until the onions are caramelized and golden brown, about 30-40 minutes.

  2. 4

    Add Liquid Ingredients

    Once the onions are caramelized, add the dry sherry and cook for another 5 minutes, scraping the bottom of the pot. Then add the beef broth, thyme, black pepper, and additional salt to taste. Bring to a simmer and let cook for 20 minutes.

Final Assembly

  1. 5

    Toast the Sourdough

    While the soup is simmering, toast the buttered sides of the sourdough bread until golden brown, either in a pan or under a broiler.

  2. 6

    Serve the Soup

    Ladle the hot soup into bowls, place a slice of toasted sourdough on top of each bowl, and generously sprinkle with provolone cheese.

  3. 7

    Melt the Cheese

    Place the bowls under a broiler for 2-3 minutes, or until the cheese is melted and bubbly. Remove from the oven and serve immediately.
