Print Recipe

A rich and savory French onion soup inspired by Longhorn Steakhouse, featuring caramelized onions, beef broth, and melted cheese topping.

Ingredients

Units Scale
  • 4 large yellow onions, thinly sliced
  • 4 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1 teaspoon sugar
  • 4 cups beef broth
  • 2 cups chicken broth
  • 1/2 cup dry white wine
  • 2 cloves garlic, minced
  • 1 tablespoon Worcestershire sauce
  • 1/2 teaspoon dried thyme
  • Salt and pepper to taste
  • 1 French baguette, sliced
  • 2 cups shredded Gruyère cheese
  • 1/2 cup shredded mozzarella cheese

Instructions

  1. In a large pot over medium heat, melt butter with olive oil.
  2. Add sliced onions and sugar; cook slowly, stirring often, until caramelized, about 30-40 minutes.
  3. Add garlic and cook for another minute until fragrant.
  4. Pour in white wine to deglaze the pot, scraping up any browned bits.
  5. Add beef broth, chicken broth, Worcestershire sauce, thyme, salt, and pepper.
  6. Bring to a boil, then reduce heat and simmer for 30 minutes.
  7. Preheat oven broiler. Place baguette slices on a baking sheet and toast until golden.
  8. Ladle soup into oven-safe bowls, top with toasted bread and a mixture of cheeses.
  9. Place bowls under broiler until cheese is bubbly and golden, about 2-3 minutes.
  10. Carefully remove and serve hot.

Notes

  • Use a combination of beef and chicken broth for a richer flavor.
  • Gruyère is traditional, but mozzarella adds great meltiness.
  • For extra depth, add a splash of balsamic vinegar before serving.
