Ingredients

• 4 large yellow onions
• 2 garlic bulbs
• 3 tablespoons olive oil
• 2 tablespoons unsalted butter
• 6 cups vegetable broth
• 0.5 cups dry white wine
• 1 bay leaf
• 4 sprigs fresh thyme
• 1 teaspoon salt
• 0.5 teaspoons black pepper
• 1 small baguette
• 1.5 cups grated Gruyère cheese

Directions

Step 1

Preheat your oven to 400°F (200°C). Slice the tops off the garlic bulbs to expose the cloves. Drizzle 1 tablespoon of olive oil over the bulbs, wrap them in aluminum foil, and roast for 30-40 minutes or until the cloves are soft and golden. Let cool, then squeeze the roasted garlic cloves out of their skins.

Step 2

While the garlic roasts, peel and thinly slice the onions.

Step 3

In a large pot, heat the remaining 2 tablespoons of olive oil and the butter over medium heat. Add the sliced onions and cook, stirring occasionally, until they are soft and caramelized, about 25-30 minutes. Be careful not to let them burn.

Step 4

Once the onions are caramelized, add the roasted garlic cloves to the pot and stir to combine.

Step 5

Deglaze the pot by pouring in the white wine. Scrape any browned bits from the bottom of the pot with a wooden spoon and let the wine simmer for 2-3 minutes until it reduces slightly.

Step 6

Add the vegetable broth, bay leaf, thyme sprigs, salt, and pepper. Stir to combine and bring the soup to a gentle boil. Reduce the heat to low, cover, and let simmer for 20 minutes to allow the flavors to meld.

Step 7

While the soup simmers, slice the baguette into 1-inch thick slices and toast them in the oven at 375°F (190°C) for 5-7 minutes or until lightly golden.

Step 8

Remove the bay leaf and thyme sprigs from the soup. Taste and adjust seasoning if needed.

Step 9

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

Step 10

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

Step 11

Carefully remove the bowls from the oven, let cool for a minute, and serve hot.
