  • Yield: 4 servings 1x

Ingredients

Scale

Main Ingredients

  • 4 large sweet yellow onions, thinly sliced
  • 6 cups beef broth
  • 2 tbsp butter
  • 1 tbsp olive oil
  • 1/2 cup dry white wine
  • 4 slices sourdough bread
  • 1 1/2 cups shredded Gruyère cheese
  • 2 cloves garlic, minced
  • 1 tsp fresh thyme leaves
  • Salt, to taste
  • Black pepper, to taste

Optional Variations

  • Vegetable broth instead of beef broth for vegetarian option
  • Swiss or mozzarella cheese as alternative to Gruyère
  • Splash of sherry for added sweetness
  • Gluten-free bread or croutons instead of sourdough
  • Pinch of smoked paprika or cayenne for spice

Instructions

  1. Caramelize the Onions: Melt butter with olive oil in a large pot over medium heat. Add thinly sliced onions and a pinch of salt. Stir occasionally and cook slowly for about 35-40 minutes until onions turn golden brown and develop a sweet, fragrant aroma.
  2. Add Aromatics and Deglaze: Stir in minced garlic and fresh thyme. Cook for another minute. Pour in the dry white wine and scrape the browned bits from the bottom of the pot to incorporate their rich flavor into the soup base.
  3. Simmer with Beef Broth: Add the beef broth to the pot. Bring to a gentle simmer and cook for 20-25 minutes, allowing the flavors to meld beautifully.
  4. Toast the Bread: While the soup simmers, slice sourdough bread and toast it until crisp but still slightly soft inside to create a perfect base for the cheese topping.
  5. Assemble and Broil: Ladle the hot soup into oven-safe bowls. Place a toasted sourdough slice on top of each bowl and generously cover with shredded Gruyère cheese. Place under the broiler for 3-5 minutes or until the cheese is bubbly and golden brown. Serve immediately.

Notes

  • Patience is key: Slow caramelization develops maximum sweetness and depth of flavor.
  • Use quality beef broth for best results.
  • Slice onions uniformly for even cooking.
  • Watch carefully when broiling the cheese to prevent burning.
  • Fresh thyme enhances the aromatic profile and balances richness.
  • Store toasted bread and cheese separately for best reheating texture.
