A warm and hearty French onion soup featuring slow-caramelized onions simmered in rich beef broth, topped with bubbling, golden Gruyere toast. Perfect for cozy winter evenings and impressing guests.

Ingredients

Scale
  • 4 large yellow onions, thinly sliced
  • 3 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 2 garlic cloves, minced
  • 6 cups beef broth (homemade or store-bought)
  • 1/2 cup dry white wine (optional)
  • 2 bay leaves
  • 2–3 sprigs fresh thyme
  • Salt and freshly ground black pepper, to taste
  • 1 loaf baguette, cut into 1/2-inch thick slices
  • 8 ounces Gruyere cheese, shredded

Instructions

  1. Peel and thinly slice 4 large yellow onions to about 1/8 inch thickness.
  2. Heat 3 tablespoons unsalted butter and 1 tablespoon olive oil in a large heavy-bottomed pot over medium-low heat.
  3. Add sliced onions and a pinch of salt; stir frequently for 40-50 minutes until onions are deep golden brown and caramelized.
  4. Add 2 minced garlic cloves and cook for 1 minute.
  5. Pour in 1/2 cup dry white wine to deglaze the pot, scraping up browned bits; simmer for 3-4 minutes until wine reduces slightly.
  6. Add 6 cups beef broth, 2 bay leaves, and 2-3 sprigs fresh thyme; bring to a gentle simmer and cook uncovered for 20-25 minutes.
  7. Season with salt and freshly ground black pepper to taste near the end of cooking.
  8. Preheat oven broiler. Arrange baguette slices on a baking sheet and toast for 1-2 minutes per side until lightly browned.
  9. Remove toasted bread, sprinkle generously with shredded Gruyere (about 2 ounces per slice), and broil for 2-3 minutes until cheese bubbles and browns slightly.
  10. Ladle hot soup into oven-safe bowls and float the cheesy toast on top or serve on the side.
  11. Optional: Place bowls under the broiler for 1 minute to melt cheese further.

Notes

Slow caramelization of onions is key for deep flavor; do not rush or increase heat. Toast bread before adding cheese to prevent sogginess. Use a heavy-bottomed pot for even heat distribution. For vegetarian version, substitute beef broth with vegetable broth and Gruyere with Emmental or mozzarella. Gluten-free bread can be used for gluten-free adaptation.
