Ingredients

• 6 large Yellow onions
• 3 tablespoons Unsalted butter
• 1 tablespoon Olive oil
• 4 sprigs Fresh thyme
• 1 Bay leaf
• 0.5 cup Dry white wine
• 8 cups Vegetable broth
• 1 teaspoon Balsamic vinegar
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 1 loaf French baguette
• 2 cups Gruyère cheese (or vegetarian alternative)

Directions

Step 1

Peel and thinly slice the onions into half-moons.

Step 2

In a large pot, melt the butter with the olive oil over medium heat.

Step 3

Add the sliced onions to the pot, stirring to coat them in the butter and oil.

Step 4

Cook the onions over medium heat, stirring occasionally, for 35-40 minutes or until deeply caramelized and golden brown.

Step 5

Add the thyme sprigs and bay leaf to the pot and stir to combine.

Step 6

Pour in the white wine, scraping the bottom of the pot with a wooden spoon to deglaze and loosen any browned bits. Cook for 2-3 minutes until the wine reduces slightly.

Step 7

Stir in the vegetable broth, balsamic vinegar, salt, and pepper. Bring to a simmer, then reduce heat to low and cook for an additional 20 minutes.

Step 8

While the soup simmers, preheat your oven's broiler. Slice the baguette into 1-inch thick rounds and toast on a baking sheet until golden brown.

Step 9

Ladle the soup into oven-safe bowls. Place a toasted baguette slice on top of each bowl and sprinkle generously with grated Gruyère cheese.

Step 10

Place the bowls on a baking sheet and transfer them to the oven. Broil for 3-5 minutes or until the cheese is melted and bubbly.

Step 11

Carefully remove from the oven and let cool for a few minutes before serving. Enjoy your Vegetarian French Onion Soup!
