Ingredients

• 6 medium Yellow onions
• 3 tablespoons Olive oil
• 2 tablespoons Vegan butter
• 3 cloves Garlic
• 1 cup Dry white wine (optional)
• 6 cups Vegetable broth
• 1 piece Bay leaf
• 4 sprigs Fresh thyme
• 1 tablespoon Balsamic vinegar
• 0.5 teaspoon Salt
• 0.25 teaspoon Black pepper
• 1 loaf French baguette
• 1 cup Vegan cheese (mozzarella-style or gruyere-style)

Directions

Step 1

Peel and thinly slice the onions into half-moons.

Step 2

Heat the olive oil and vegan butter in a large stockpot over medium heat.

Step 3

Add the sliced onions and cook, stirring occasionally, for 30-40 minutes until deeply caramelized and golden brown. Adjust the heat to medium-low if necessary to prevent burning.

Step 4

Mince the garlic and add it to the pot. Cook for 1-2 minutes until fragrant.

Step 5

Deglaze the pot with the dry white wine (if using), scraping up any browned bits from the bottom. Cook for 2-3 minutes to reduce the wine slightly.

Step 6

Pour in the vegetable broth and add the bay leaf and thyme sprigs. Bring the soup to a simmer and let it cook for 15-20 minutes.

Step 7

Remove the bay leaf and thyme sprigs. Stir in the balsamic vinegar, salt, and pepper. Taste and adjust seasoning as needed.

Step 8

While the soup is simmering, preheat the oven to 375°F (190°C). Slice the baguette into 1-inch thick slices and place them on a baking sheet.

Step 9

Toast the baguette slices in the oven for 5-7 minutes until golden and crispy.

Step 10

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

Step 11

Place the bowls on a baking sheet and broil in the oven for 2-4 minutes until the cheese is melted and bubbling. Keep a close eye to prevent burning.

Step 12

Carefully remove the bowls from the oven. Serve the soup hot, garnished with extra thyme if desired.
