A classic French onion soup recipe with deeply caramelized onions in a rich beef broth, topped with golden, cheesy toast.

Ingredients

Scale
  • 4 large yellow onions, thinly sliced
  • 4 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 1 teaspoon granulated sugar
  • 1 teaspoon salt
  • 1 teaspoon black pepper
  • 2 cloves garlic, minced
  • 8 cups beef broth
  • 1 cup dry white wine
  • 1 tablespoon fresh thyme leaves
  • 1 bay leaf
  • Baguette slices
  • Gruyere cheese, grated

Instructions

  1. In a large pot or Dutch oven, melt butter with olive oil over medium heat. Add onions and sugar, stirring to coat. Cook, stirring occasionally, for 30-45 minutes, until onions are deeply caramelized and golden brown.
  2. Stir in salt, pepper, and minced garlic. Cook for 1 minute more until fragrant.
  3. Pour in white wine and scrape up any browned bits from the bottom of the pot. Let it simmer and reduce for 5 minutes.
  4. Add beef broth, thyme leaves, and bay leaf. Bring to a simmer, then reduce heat to low, cover, and cook for at least 30 minutes to allow flavors to meld. Remove bay leaf.
  5. Preheat your broiler.
  6. Ladle soup into oven-safe bowls. Top each bowl with a few baguette slices and a generous amount of grated Gruyere cheese.
  7. Place bowls on a baking sheet and broil for 2-3 minutes, or until cheese is melted, bubbly, and golden brown.

Notes

  • For extra depth of flavor, you can caramelize the onions low and slow for even longer.
  • If you don’t have dry white wine, you can omit it or use a splash of sherry.
  • Ensure your bowls are broiler-safe before placing them under the heat.
