Ingredients

Scale

Vegetables and Aromatics

  • 4 large sweet onions (yellow or Vidalia), thinly sliced
  • 3 garlic cloves, minced
  • 1 tsp fresh thyme leaves
  • Salt and pepper, to taste

Fats and Liquids

  • 2 tbsp butter
  • 1 tbsp olive oil
  • 1/2 cup dry white wine or sherry
  • 6 cups beef broth or vegetable broth

Soup Components

  • 1 lb store-bought or homemade gnocchi
  • 1 1/2 cups grated Gruyere cheese
  • Baguette slices or croutons, for topping (optional)

Instructions

  1. Caramelize the onions: Thinly slice your onions. In a large pot, heat butter and olive oil over medium-low heat. Slowly cook the onions, stirring occasionally, until they turn deep golden brown and sweet, about 40-50 minutes, to build a rich flavor base.
  2. Add garlic and deglaze: Stir in minced garlic and cook for about 1 minute until fragrant. Pour in dry white wine or sherry to deglaze the pot, scraping up browned bits from the bottom. Allow the wine to reduce by half to concentrate flavor.
  3. Pour in broth and simmer: Add beef or vegetable broth and fresh thyme. Bring to a gentle boil, then reduce heat and simmer for 20 minutes. Season with salt and pepper to taste.
  4. Cook the gnocchi: Cook gnocchi in a separate pot according to package instructions until they float, indicating they are done. Drain and gently fold into the soup just before serving.
  5. Assemble and melt Gruyere: Ladle the soup into oven-safe bowls. Top with toasted baguette slices or croutons and generously pile grated Gruyere cheese on top. Place under a broiler until the cheese is melted, bubbly, and golden brown.

Notes

  • Be patient caramelizing onions: low and slow cooking maximizes sweetness and prevents bitterness.
  • Use good-quality broth for a rich, deep flavor.
  • Don’t skip the wine; it adds acidity and balances the sweetness.
  • Toast bread lightly to keep it from getting soggy under the cheese.
  • Serve immediately for best melty Gruyere texture.
  • Fresh thyme adds bright herbal notes balancing richness.
