Classic French Onion Soup with Toasts

Instructions

1. 1

   Peel and thinly slice the yellow onions.

2. 2

   In a large pot, heat the olive oil and unsalted butter over medium heat until the butter is melted.

3. 3

   Add the sliced onions and sprinkle with salt. Cook, stirring frequently, for 30-40 minutes until the onions are deeply caramelized and golden brown.

4. 4

   Add the black pepper and stir to combine.

5. 5

   Pour in the low-sodium vegetable broth and bring the soup to a simmer. Reduce the heat and let it simmer gently for 15-20 minutes to allow the flavors to meld.

6. 6

   While the soup simmers, preheat your oven broiler. Arrange the whole wheat baguette slices on a baking sheet and toast under the broiler for 1-2 minutes per side, until golden and crisp.

7. 7

   Ladle the hot soup into oven-safe bowls. Place a toasted baguette slice on top of each bowl of soup and sprinkle generously with grated Gruyère cheese.

8. 8

   Place the bowls under the broiler for 2-3 minutes, or until the cheese is melted and bubbly.

9. 9

   Carefully remove from the oven and serve the soup hot, enjoying the cheesy toasts on top.
