The Origins and Charm of French Onion Soup
French Onion Soup, or ‘Soupe à l’Oignon,’ is a recipe that dates back to Roman times, but it was the French who elevated it to the level of gourmet comfort food. Traditionally a humble dish made by simmering caramelized onions in a rich meat stock, it’s served gratinéed with croutons and cheese on top, usually Gruyère or a similar variety.
Ingredients:
- 5 large onions, thinly sliced
- 4 tablespoons unsalted butter
- 2 tablespoons olive oil
- 1 teaspoon sugar
- Salt and freshly ground black pepper, to taste
- 2 cloves garlic, minced
- 8 cups of beef stock
- 1/2 cup dry white wine
- 2 bay leaves
- 1/4 teaspoon dried thyme
- 1 baguette, sliced and toasted
- 1 1/2 cups grated Gruyère cheese
- Fresh parsley, for garnish
Instructions:
Caramelizing the Onions:
- Start with Onions: In a large, heavy-bottomed pot, melt butter with olive oil over medium heat. Add the sliced onions and toss to coat. Cook, stirring occasionally, until they begin to soften and turn translucent.
- Sweeten the Pot: Sprinkle sugar over the onions, and reduce the heat to medium-low. This little addition helps with caramelization, giving the onions a beautiful golden-brown hue and a deep, sweet flavor. Continue to cook, stirring frequently to prevent the onions from sticking, until they are richly browned. This could take about 40 minutes – patience is key here.
Building the Soup:
- Add Garlic: Stir in the minced garlic and cook for another minute until fragrant.
- Deglaze: Pour in the white wine and increase the heat to medium-high. Let it simmer and reduce slightly, which will cook off the alcohol and leave behind the wine’s essence.
- Simmer: Add the beef stock, bay leaves, and thyme. Season with salt and pepper. Bring the mixture to a boil, then lower the heat and simmer for about 30 minutes to melt the flavors.
Preparing the Gratinee:
- Toast Baguette Slices: While the soup simmers, place sliced baguette pieces under the broiler and toast until they’re golden brown on both sides.
- Gratinée: Preheat the broiler. Ladle the soup into oven-safe bowls. Place toasted baguette slices on top of the soup, then generously sprinkle grated Gruyère cheese over the bread.
- Broil: Place the bowls under the broiler and cook until the cheese is bubbly and browned, about 2-3 minutes.
Serving:
- Garnish and Serve: Carefully remove the hot bowls, garnish with fresh parsley, and serve immediately. Watch as the cheese stretches with each spoonful, and the savory aroma of the soup fills the air.
