A warm and satisfying French onion soup featuring slowly caramelized onions and melty Gruyere cheese croutons, perfect for cozy meals and chilly evenings.

Ingredients

Scale
  • 4 large yellow onions, thinly sliced
  • 3 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 2 garlic cloves, minced
  • 6 cups beef broth (low-sodium preferred)
  • 1/2 cup dry white wine (optional)
  • 1 bay leaf
  • 2 sprigs fresh thyme (or 1/2 teaspoon dried thyme)
  • Salt and freshly ground black pepper, to taste
  • 8 slices baguette, about 1/2-inch thick
  • 2 cups (200 g) Gruyere cheese, grated

Instructions

  1. Slice the onions thinly and evenly, about 1/8-inch thickness.
  2. Heat butter and olive oil in a large heavy-bottomed pot or Dutch oven over medium heat until melted and shimmering.
  3. Add the sliced onions and stir to coat them in fat. Cook gently, stirring every 5 minutes, for 35-40 minutes until onions are golden brown and caramelized.
  4. Add minced garlic, bay leaf, and thyme sprigs; cook for 2 minutes until fragrant.
  5. Pour in dry white wine and scrape up browned bits from the pot bottom. Let wine reduce for 3-4 minutes.
  6. Add beef broth, bring to a simmer, season with salt and pepper to taste, and cook gently for 20 minutes. Remove bay leaf and thyme sprigs before serving.
  7. While soup simmers, preheat oven broiler. Arrange baguette slices on a baking sheet and toast for 2-3 minutes per side until lightly golden.
  8. Ladle hot soup into ovenproof bowls, place toasted baguette slices on top, and pile on 1/4 cup grated Gruyere per bowl.
  9. Place bowls under broiler for 3-5 minutes until cheese melts, bubbles, and turns golden brown. Watch carefully to avoid burning.
  10. Let cool for a minute or two and serve immediately.

Notes

Caramelize onions low and slow to avoid bitterness. Stir every 5 minutes. Use a wide pot for even cooking. Deglaze with wine to add flavor and prevent burning. Grate Gruyere finely for even melting. Watch cheese closely under broiler to prevent burning. For vegetarian version, use vegetable broth and omit or replace wine with apple cider vinegar. For dairy-free, substitute butter with coconut oil and Gruyere with plant-based melting cheese.
