Ingredients
Scale
Soup
- 4 medium yellow onions, thinly sliced
- 4 tbsp unsalted butter
- 6 cups beef broth
- ½ cup dry white wine
Topping
- 1 fresh baguette, sliced
- 2 cups grated Gruyère cheese
Instructions
- Prepare Onions: Slice the onions thinly to ensure even caramelization during cooking.
- Caramelize Onions: In a large pot, melt the unsalted butter over medium heat, then add the sliced onions. Stir frequently and cook for 20-25 minutes until the onions turn golden brown and develop a rich, sweet flavor.
- Deglaze Pot: Pour in the dry white wine to deglaze the pot, scraping up any browned bits stuck to the bottom to incorporate deep flavor into the soup base.
- Simmer Soup: Add the beef broth to the pot and bring to a simmer. Let it cook gently for 15-20 minutes to meld the flavors together.
- Toast Baguette: While the soup simmers, toast the baguette slices in the oven or a toaster until they are golden brown and crisp.
- Assemble and Broil: Ladle the hot soup into oven-safe bowls. Place toasted baguette slices on top of the soup, then generously sprinkle with grated Gruyère cheese. Place the bowls under a broiler for 3-5 minutes until the cheese is melted, bubbly, and slightly browned.
Notes
- Use good quality beef broth for a richer flavor.
- Cooking onions slowly is key for sweetness; avoid high heat to prevent burning.
- You can substitute Gruyère with Swiss cheese if unavailable.
- Serve immediately after broiling to enjoy the gooey cheese topping.
- Careful when handling hot bowls after broiling; use oven mitts.
