French Onion Soup

Prep Time 15 minutes
Cook Time 1 hour 10 minutes
Total Time 1 hour 25 minutes
Makes 6 servings

Ingredients

  • 1/4 cup unsalted butter
  • 4 large yellow onions thinly sliced, about 3 lbs
  • 1 teaspoon sugar
  • 1 teaspoon salt
  • 2 cloves garlic minced
  • 1/2 cup dry sherry or dry white wine
  • 8 cups beef broth
  • 2 sprigs fresh thyme
  • 1 bay leaf
  • Black pepper
  • 1 baguette sliced into 1 inch rounds
  • 2 cups shredded Gruyere cheese

Instructions

  • Melt the butter in a large Dutch oven over medium heat.
  • Add the onions, sugar and salt, stirring to coat.
  • Cook the onions 40 to 45 minutes, stirring every 5 minutes, until they are deep caramel brown and jammy, lowering the heat if they start to scorch.
  • Add the garlic and cook 1 minute until fragrant.
  • Pour in the sherry, scraping up the browned bits, and simmer 2 minutes until mostly evaporated.
  • Add the beef broth, thyme, bay leaf and 1/2 teaspoon pepper, and bring to a simmer.
  • Simmer uncovered 20 minutes, then discard the thyme stems and bay leaf.
  • Meanwhile, toast the baguette slices on a baking sheet under the broiler 1 to 2 minutes per side until golden.
  • Ladle the soup into oven-safe crocks, float 2 toasted baguette slices on top of each, and mound with the Gruyere.
  • Broil 2 to 3 minutes until the cheese is melted, bubbling and browned in spots.

Good to Know

The caramelized onion and broth base keeps well for 3 days in the fridge or 2 months frozen; just make the fresh toast and cheese topping the day you serve it.
