How to Make Real French Onion Soup

  1. **Prep the Onions:** Peel and thinly slice 3 large yellow onions (about 2 lbs) in a well-ventilated area (onions can make you cry!).
  2. **Caramelize the Onions:** Melt 4 tablespoons of unsalted butter in a large, heavy-bottomed pot or Dutch oven over medium heat. Add the sliced onions and stir well. Cover and cook for about 40 minutes, stirring every 5-10 minutes, until softened.
  3. **Continue Caramelization:** Remove the lid, add 2 teaspoons of sugar, increase the heat slightly, and simmer for another 20-30 minutes, or until almost all the liquid has evaporated and onions are deeply caramelized. Stir frequently to prevent burning.
  4. **Golden Brown Perfection:** Reduce heat to low and stir constantly for 10-15 minutes, scraping the bottom of the pot, until the onions are a rich, deep golden brown. This is crucial for flavor!
  5. **Deglaze and Simmer:** Add 1/2 cup of dry vermouth and boil for a few minutes until it evaporates. Add 6 cups of high-quality beef stock, 2 bay leaves, salt, and freshly ground black pepper. Simmer gently for 30 minutes, stirring occasionally.
  6. **Toast the Bread:** While the soup simmers, toast 6 slices of crusty French bread until golden brown.
  7. **Assemble and Broil:** Ladle the soup into oven-safe bowls. Top each bowl with a slice of toasted bread, and then generously sprinkle with 1 1/2 cups of grated Gruyère cheese.
  8. **Broil to Perfection:** Broil in a preheated oven until the cheese is melted, bubbly, and golden brown.
  9. **Serve and Enjoy:** Serve immediately with extra crusty bread. Enjoy the delicious result of your hard work!
