How to Make Longhorn French Onion Soup?

Step 1:

Start by heating the butter and olive oil in a large stockpot over medium heat. Add the sliced onions and cook, This should take about 10 minutes. Sprinkle the onions with sugar and continue to cook, until they are deeply caramelized, which will take another 30-40 minutes.

Step 2:

Once the onions are caramelized, add the minced garlic and cook for another minute. Pour in the white wine to deglaze the pot, scraping up any browned bits from the bottom.

Step 3:

Add the beef broth, bay leaves, and thyme to the pot. Bring the mixture to a boil, then reduce the heat and let it simmer for about 30 minutes. Season the soup with salt and freshly ground black pepper to taste. Remove the bay leaves before serving.

Step 4:

While the soup is simmering, preheat your oven to 400°F (200°C). Arrange the baguette slices on a baking sheet and toast them in the oven until they are crispy. This should take about 10 minutes. Once toasted, remove the bread from the oven and set it aside.

Step 5:

Ladle the hot soup into oven-safe bowls. Top each bowl with a slice or two of the toasted baguette and a generous handful of grated Gruyère cheese. Place the bowls on a baking sheet and transfer them to the oven. Broil the soup for 2-3 minutes, until you see the cheese melted, Then enjoy it.
