Ingredients

Scale

Soup Base

  • 1/2 cup salted butter
  • 4 sweet onions, sliced
  • 8 cups beef broth
  • 1/4 cup cooking sherry
  • 1/2 Tablespoon granulated sugar (optional)
  • 2 Tablespoons all purpose flour
  • 2 1/2 teaspoons salt
  • 2 teaspoons Worcestershire sauce
  • 2 bay leaves, dried
  • 2 sprigs fresh thyme

Noodles and Toppings

  • 12 ounce bag egg noodles
  • 8 ounces Swiss or Gruyere cheese, shredded


Instructions

  1. Caramelize Onions: Melt the salted butter in a large soup pot over medium heat. Add the sliced sweet onions and cook over medium heat, stirring regularly to prevent burning, until the onions are deeply caramelized and have turned a rich golden brown color. This process should take about 20-25 minutes, developing a sweet and savory flavor base for the soup.
  2. Create Soup Base: To the caramelized onions, add beef broth, cooking sherry, granulated sugar (if using), all-purpose flour, salt, and Worcestershire sauce. Whisk everything together until the flour is fully incorporated and the mixture is smooth, which will help thicken the soup slightly.
  3. Add Herbs and Noodles: Stir in the dried bay leaves, fresh thyme sprigs, and egg noodles. Bring the soup to a boil over medium-high heat.
  4. Simmer: Once boiling, reduce the heat to low and let the soup simmer gently for about 30 minutes, or until the egg noodles are fully cooked and tender. This simmering also allows the flavors to meld beautifully.
  5. Finish and Serve: Remove the bay leaves and thyme sprigs from the soup. Ladle the soup into bowls, topping each serving with a generous amount of shredded Swiss or Gruyere cheese. Garnish with fresh thyme and freshly ground black pepper if desired. Serve hot and enjoy!

Notes

  • The granulated sugar is optional but helps enhance the sweetness and caramelization of the onions.
  • If you prefer a vegetarian version, substitute beef broth with vegetable broth and omit Worcestershire sauce or use a vegetarian-friendly brand.
  • Use freshly grated cheese for better melting and flavor.
  • To make it gluten free, use gluten-free flour and noodles or substitute with rice noodles.
  • Leftovers keep well refrigerated for up to 3 days and reheat gently on the stovetop.
