This Buttery Onion Soup is a comforting twist on the classic French onion soup, but with an added richness that comes from a generous amount of butter. The onions are slowly caramelized to bring out their natural sweetness, and then simmered in a flavorful broth until they are tender and infused with the taste of fresh herbs. Topped with toasted baguette slices and melted cheese, this soup is perfect for a cozy night in or as an impressive starter for a dinner party.
Ingredients:
- 6 large yellow onions, thinly sliced
- 6 tablespoons unsalted butter
- 2 cloves garlic, minced
- 1 teaspoon sugar
- 2 tablespoons all-purpose flour
- 8 cups beef or vegetable broth
- 1/2 cup dry white wine (optional)
- 2 teaspoons fresh thyme leaves (or 1 teaspoon dried thyme)
- Salt and pepper to taste
- 1 baguette, sliced into 1/2-inch thick rounds
- 2 cups Gruyère cheese, shredded
Instructions:
- Caramelize the Onions: In a large pot, melt the butter over medium heat. Add the sliced onions and cook, stirring occasionally, for about 30 minutes, until the onions are soft and golden brown. Sprinkle the sugar over the onions to help with caramelization.
- Add Garlic and Flour: Add the minced garlic to the pot and cook for another minute until fragrant. Stir in the flour and cook for 2-3 minutes, stirring constantly to avoid lumps.
- Simmer the Soup: Gradually add the broth, stirring constantly to combine. Add the white wine (if using), thyme, salt, and pepper. Bring the soup to a boil, then reduce the heat and let it simmer for 20-30 minutes to allow the flavors to meld together.
- Prepare the Toppings: While the soup is simmering, preheat your oven to 400°F (200°C). Arrange the baguette slices on a baking sheet and toast them in the oven for 5-7 minutes until they are golden and crispy.
- Assemble and Serve: Ladle the hot soup into oven-safe bowls, place a few toasted baguette slices on top of each, and sprinkle generously with the shredded Gruyère cheese. Place the bowls under the broiler for 2-3 minutes until the cheese is melted and bubbly. Serve immediately.
