Instructions

  1. 1

    Slice the onions thinly (about 1/8 inch thick). Mince the garlic cloves.

  2. 2

    In a large pot, melt the butter and olive oil over medium heat (about 350°F).

  3. 3

    Add the sliced onions and a pinch of salt. Cook, stirring occasionally, for about 25-30 minutes until the onions are caramelized and golden brown.

  4. 4

    Add the minced garlic and cook for an additional 2 minutes until fragrant.

  5. 5

    Pour in the white wine and scrape the bottom of the pot to deglaze. Let it simmer for about 5 minutes until slightly reduced.

  6. 6

    Add the beef broth, thyme, bay leaf, black pepper, and salt. Bring the soup to a boil, then reduce heat to low and simmer for 20 minutes.

  7. 7

    While the soup simmers, preheat your broiler to high.

  8. 8

    Slice the baguette into 1-inch thick slices and place them on a baking sheet. Toast under the broiler for about 2-3 minutes on each side until golden brown.

  9. 9

    Remove the bay leaf from the soup and ladle the soup into oven-safe bowls.

  10. 10

    Place a slice of toasted baguette on top of each bowl of soup, then generously sprinkle Gruyère cheese over the bread.

  11. 11

    Broil the bowls in the oven for about 3-5 minutes, or until the cheese is bubbly and golden.

  12. 12

    Carefully remove the bowls from the oven and let them cool slightly before serving.

  13. 13

    Enjoy your Soupe à l'Oignon Gratinée hot, garnished with additional thyme if desired.
