*garlic
*Worcestershire sauce
*salt
*pepper
*French bread
*Gruyère cheese

Directions

Storage/Reheating

Store leftover Longhorn French Onion Soup in an airtight container in the fridge for up to 3 days. To reheat, warm the soup on the stovetop and top with fresh cheese before broiling for a few minutes.

Description

A savory and hearty French Onion Soup inspired by the flavors of Longhorn Steakhouse, featuring caramelized onions, rich beef broth, and melted cheese on top of toasted bread.


Ingredients

  • 4 large onions, thinly sliced
  • 4 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 4 cups beef broth
  • 1 cup dry white wine
  • 2 teaspoons fresh thyme leaves
  • 1 bay leaf
  • Salt and pepper to taste
  • 4 slices of French bread, toasted
  • 2 cups shredded Gruyère cheese
  • 1 cup shredded mozzarella cheese
  • 1 tablespoon flour (optional, for thickening)


Instructions

  1. In a large pot, melt butter with olive oil over medium heat. Add onions and cook, stirring occasionally, until golden brown and caramelized, about 30-40 minutes.
  2. If you prefer a thicker soup, sprinkle flour over the onions and cook for 1-2 minutes, stirring constantly.
  3. Deglaze the pot by adding white wine and scraping up any bits from the bottom. Let the wine reduce for about 3 minutes.
  4. Add the beef broth, thyme, and bay leaf to the pot. Bring to a simmer and cook for 15-20 minutes. Season with salt and pepper to taste.
  5. Meanwhile, toast the French bread slices in a toaster or under a broiler until crispy and golden.
  6. Preheat your broiler. Ladle the soup into oven-safe bowls, placing a slice of toasted French bread on top of each bowl.
  7. Top each slice of bread with a generous amount of shredded Gruyère and mozzarella cheese.
  8. Broil the soup for 3-5 minutes, until the cheese is melted, bubbly, and golden brown.
  9. Serve hot, garnished with extra thyme if desired.

Notes

  • For a richer flavor, you can use a combination of beef and chicken broth.
  • If you prefer a vegetarian version, substitute vegetable broth for the beef broth.
  • For a more robust taste, you can add a splash of brandy or cognac during the deglazing step.
  • The cheese blend of Gruyère and mozzarella is essential for that signature melty, gooey texture.
