A comforting and easy-to-make French onion soup recipe designed for solo dining, featuring slow caramelized onions, rich beef broth, and a bubbly Gruyère cheese crust.

Ingredients

Scale
  • 2 medium yellow onions, thinly sliced
  • 2 tablespoons unsalted butter
  • 1 tablespoon olive oil
  • 2 garlic cloves, minced
  • 2 cups (16 fl oz) beef broth
  • 1/4 cup (2 fl oz) dry white wine (optional)
  • 2 sprigs fresh thyme
  • 1 bay leaf
  • Salt and freshly ground black pepper, to taste
  • 1 slice baguette (about 1/2 inch thick), toasted
  • 1/2 cup (50 grams) shredded Gruyère cheese

Instructions

  1. Peel and thinly slice about 2 medium yellow onions into uniform 1/8-inch thick slices.
  2. Heat 2 tablespoons unsalted butter and 1 tablespoon olive oil in a Dutch oven over medium heat until butter melts and foams.
  3. Add sliced onions and a pinch of salt; stir to coat evenly. Cook slowly, stirring every few minutes, letting onions soften and turn golden brown over 30-40 minutes. Lower heat if onions stick or brown too fast.
  4. Stir in 2 minced garlic cloves and cook for 1 minute until fragrant.
  5. Pour in 1/4 cup dry white wine (or extra broth) and scrape up browned bits from the bottom of the pot.
  6. Add 2 cups beef broth, 2 sprigs fresh thyme, and 1 bay leaf. Bring to a simmer and cook gently for 15 minutes. Season with salt and pepper to taste.
  7. While soup simmers, toast a 1/2-inch thick slice of baguette until golden and crisp. Shred 1/2 cup Gruyère cheese finely.
  8. Remove thyme sprigs and bay leaf from soup. Pour soup into an oven-safe bowl or small casserole dish. Place toasted baguette slice on top and sprinkle shredded Gruyère cheese generously over it.
  9. Broil under a hot broiler for 3-5 minutes, watching closely until cheese bubbles and turns golden brown.
  10. Carefully remove from oven, let cool slightly, and serve immediately.

Notes

Use low and slow heat to caramelize onions for best flavor. Watch the broiler carefully to avoid burning the cheese. For vegetarian version, substitute beef broth with mushroom or vegetable broth and omit wine. Gluten-free bread can be used instead of baguette. Cheese alternatives include Swiss or mozzarella but Gruyère is preferred.
