Ingredients

  • 3 large Onions
  • 6 cups Beef broth
  • 1/2 cup Dry red wine
  • 4 tablespoons Butter
  • 2 tablespoons Olive oil
  • 2 cloves Garlic
  • 1 teaspoon Thyme
  • 1 Bay leaf
  • 1 tablespoon Worcestershire sauce
  • 4 oz Swiss cheese
  • to taste Salt
  • to taste Pepper

Instructions

  1. 1Prepare the 3 large onions by slicing them thinly. Mince the 2 cloves of garlic.
  2. 2In a large, heavy-bottomed pot or Dutch oven, melt the 4 tablespoons of butter with the 2 tablespoons of olive oil over medium heat (350°F/175°C). Add the sliced onions and cook, stirring occasionally, for 30-40 minutes, or until they are deeply caramelized and have a rich brown color. This slow caramelization is key to the soup's flavor.
  3. 3Add the minced garlic to the pot and cook for 1 minute more, until fragrant.
  4. 4Pour in the 1/2 cup of dry red wine. Scrape the bottom of the pot with a wooden spoon to loosen any browned bits, which will add depth to the soup.
  5. 5Add the 6 cups of beef broth, 1 teaspoon of thyme, 1 bay leaf, and 1 tablespoon of Worcestershire sauce. Stir everything together. Bring the soup to a simmer, then reduce the heat to low, cover, and cook for 15 minutes.
  6. 6Season the soup with salt and pepper to your taste.
  7. 7Carefully ladle the hot soup into 4 oven-safe bowls. Place a slice or portion of the 4 oz Swiss cheese on top of each bowl of soup.
  8. 8Place the bowls on a baking sheet and put them under a preheated broiler. Broil for 1-3 minutes, watching closely, until the Swiss cheese is melted, bubbly, and lightly browned. Remove the bay leaf from the soup before serving.
