Ingredients

• 3 tablespoons unsalted butter
• 2 tablespoons olive oil
• 6 cups yellow onions, sliced thinly
• 2 cloves garlic, minced
• 1 teaspoon granulated sugar
• 0.5 cups dry white wine
• 6 cups beef or vegetable broth
• 1 bay leaf
• 1 teaspoon dried thyme
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 8 slices baguette, sliced
• 1.5 cups grated Gruyère cheese
• 0.5 cups Parmesan cheese, grated

Directions

Step 1

In a large stockpot, heat the unsalted butter and olive oil over medium heat until the butter melts.

Step 2

Add the sliced onions and cook, stirring occasionally, for 10 minutes until softened.

Step 3

Stir in the minced garlic and granulated sugar. Continue cooking the onions on medium-low heat, stirring frequently, for 20-25 minutes until they are deeply golden and caramelized.

Step 4

Deglaze the pot by adding the dry white wine. Stir well, scraping up any brown bits from the bottom of the pot, and cook for 2-3 minutes until the wine reduces slightly.

Step 5

Add the beef or vegetable broth, bay leaf, dried thyme, salt, and black pepper. Bring the soup to a gentle boil, then reduce the heat and let it simmer for 20 minutes to allow the flavors to meld.

Step 6

While the soup is simmering, preheat your oven's broiler. Arrange the baguette slices on a baking sheet and toast them under the broiler for 2 minutes per side or until golden brown.

Step 7

Ladle the soup into ovenproof bowls. Place a toasted baguette slice on top of each bowl of soup.

Step 8

Top each baguette slice with a generous amount of grated Gruyère cheese and a sprinkle of Parmesan cheese.

Step 9

Place the bowls on a baking sheet and broil in the oven for 3-5 minutes or until the cheese is melted, bubbly, and golden brown.

Step 10

Carefully remove the bowls from the oven and let cool slightly before serving. Enjoy your hearty Cheese Onion Soup!
