Ingredients

• 3 tablespoons unsalted butter
• 2 tablespoons olive oil
• 6 medium (thinly sliced) yellow onions
• 3 cloves (minced) garlic
• 1 teaspoon granulated sugar
• 1 cup dry white wine
• 2 tablespoons all-purpose flour
• 4 cups beef broth
• 1 cup heavy cream
• 2 cups (shredded) Swiss cheese
• 1 loaf (sliced and toasted) baguette
• 1 teaspoon (to taste) salt
• 0.5 teaspoon (to taste) black pepper
• 1 teaspoon (optional, for garnish) fresh thyme leaves

Directions

Step 1

In a large pot or Dutch oven, heat the butter and olive oil over medium heat until melted.

Step 2

Add the thinly sliced onions to the pot and cook, stirring occasionally, for about 25-30 minutes, or until the onions are deeply caramelized and golden brown.

Step 3

Stir in the minced garlic and granulated sugar, and cook for an additional 2 minutes, stirring frequently.

Step 4

Deglaze the pot by pouring in the white wine. Scrape the bottom of the pot to release any browned bits, and let the wine simmer for 3-4 minutes until reduced by half.

Step 5

Sprinkle the flour over the onion mixture and stir well. Cook for 2 minutes to eliminate the raw flour taste.

Step 6

Gradually pour in the beef broth while stirring to prevent lumps. Bring the soup to a simmer and let it cook for 15 minutes, allowing the flavors to meld together.

Step 7

Reduce the heat to low and stir in the heavy cream. Heat through, but do not let it boil.

Step 8

Add the shredded Swiss cheese in small batches, stirring constantly until fully melted and incorporated into the soup.

Step 9

Taste the soup and adjust seasoning with salt and black pepper as needed.

Step 10

Ladle the soup into bowls. Top with a toasted baguette slice and an additional sprinkle of Swiss cheese, allowing it to melt slightly. Garnish with fresh thyme leaves if desired.

Step 11

Serve warm and enjoy the creamy and flavorful soup!
