Equipment

  • Heavy-bottomed pot

Ingredients
  

For the Soup

  • 4 medium Onions Select yellow onions for sweetness
  • 4 tbsp Butter Unsalted for rich flavor
  • 6 cups Beef Broth Substitute with vegetable broth for vegetarian
  • 1/2 cup Dry White Wine Optional for deglazing
  • 1 tsp Thyme Fresh or dried

For the Topping

  • 2 cups Gruyère Cheese Freshly shredded
  • 1 loaf Baguette Toast for crunchy topping, gluten-free bread works well

Instructions
 

  • In a heavy-bottomed pot, melt unsalted butter over low heat. Add sliced yellow onions and cook gently for about 40 minutes, stirring frequently, until they become soft, golden, and beautifully caramelized.
  • Once the onions are caramelized, add a splash of dry white wine, making sure to scrape the bottom of the pot to lift all those delicious bits.
  • Pour in the beef broth and sprinkle in the fresh or dried thyme. Allow the soup to simmer for 10-15 minutes, giving the flavors a chance to blend beautifully.
  • While the soup simmers, slice the baguette and toast it in the oven until it's slightly crispy.
  • Ladle the warm soup into oven-safe bowls. Top each bowl with a toasted baguette slice and a generous heap of shredded Gruyère cheese. Place under the broiler for 3-5 minutes, or until the cheese is bubbly and golden brown.

Notes

For best results, garnish with fresh thyme leaves before serving. Store leftovers in an airtight container for up to 3 days. Freezer-friendly for up to 3 months without bread and cheese.
