Ingredients Method Notes

Ingredients
  

  • 4 cups thinly sliced onions
  • 5 cups beef broth
  • ½ cup unsalted butter
  • 2 tablespoons olive oil
  • 2 tablespoons dry sherry
  • 1 teaspoon dried thyme
  • Salt and freshly ground black pepper to taste
  • 4 slices French bread
  • 4 slices provolone cheese
  • 2 slices Swiss cheese diced
  • ¼ cup grated Parmesan cheese

Method
 

  1. Gather and prepare all ingredients before beginning.
  2. In a large stockpot, approximately 8 quarts in capacity, melt the butter with the olive oil over medium heat. Add the sliced onions and stir frequently until they become soft and translucent, taking care not to brown them to preserve their natural sweetness.
  3. Pour in the beef broth, then incorporate the dry sherry and thyme. Season with salt and pepper as desired. Allow the soup to simmer gently for about 30 minutes so the flavors can meld harmoniously.
  4. Preheat the oven broiler.
  5. After simmering, ladle the soup into ovenproof bowls. Place a slice of French bread atop each serving. If preferred, break the bread into smaller pieces to fit. Layer each with a slice of provolone cheese, half of a diced Swiss slice, and a sprinkling of Parmesan.
  6. Arrange the filled bowls on a baking sheet and place under the broiler. Heat until the cheeses melt, bubble, and develop a light golden hue, about 2 to 3 minutes.
