Ingredients

• 6 medium red onions
• 3 tablespoons olive oil
• 2 tablespoons butter
• 2 garlic cloves
• 2 teaspoons fresh thyme
• 1 bay leaf
• 1 cup dry white wine
• 6 cups beef or vegetable stock
• 1 teaspoon salt
• 0.5 teaspoons black pepper
• 8 baguette slices
• 0.5 cup grated Parmesan cheese

Directions

Step 1

Peel and thinly slice the red onions into rings.

Step 2

In a large, heavy-bottomed pot, heat the olive oil and butter over medium heat until the butter melts.

Step 3

Add the sliced red onions to the pot. Cook for about 25-30 minutes, stirring occasionally, until the onions are deeply caramelized and golden brown. Reduce heat if they start to brown too quickly.

Step 4

Mince the garlic cloves and add them to the pot along with the fresh thyme and bay leaf. Cook for 1-2 minutes, until fragrant.

Step 5

Pour in the dry white wine to deglaze the pot, scraping up any browned bits from the bottom. Simmer for 3-4 minutes until the wine reduces by half.

Step 6

Add the beef or vegetable stock to the pot and bring the soup to a boil. Reduce heat to low and let it simmer for 20 minutes, allowing the flavors to meld together.

Step 7

Season the soup with salt and black pepper to taste. Remove the bay leaf before serving.

Step 8

While the soup simmers, lightly toast the baguette slices under a broiler or in a toaster until golden brown.

Step 9

To serve, ladle the soup into bowls, place a toasted baguette slice on top, and sprinkle with grated Parmesan cheese. Optionally, broil the bowls for a few minutes to melt the cheese.
