Ingredients

  • 4 tablespoons unsalted butter
  • 1 1/2 pounds pearl onions (peeled)
  • 4 cloves garlic (minced)
  • 1 tablespoon granulated sugar
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 2 tablespoons all-purpose flour
  • 1 cup dry white wine
  • 6 cups beef or vegetable broth
  • 2 sprigs fresh thyme
  • 1 bay leaf
  • 1 tablespoon Worcestershire sauce
  • 1 baguette (sliced)
  • 2 cups grated Gruyère cheese

Instructions

Step 1: Prepare the Pearl Onions

  1. To easily peel pearl onions, blanch them in boiling water for 1-2 minutes, then transfer them to an ice bath. Trim the ends and remove the skins.

Step 2: Caramelize the Onions

  1. In a large Dutch oven or soup pot, melt the butter over medium heat.
  2. Add the peeled pearl onions and cook for 10-15 minutes, stirring occasionally, until the onions are deeply caramelized and golden brown.
  3. Add the minced garlic, sugar, salt, and black pepper, and cook for an additional 2-3 minutes until fragrant.

Step 3: Make the Broth

  1. Sprinkle the flour over the onions and stir until the flour is fully incorporated, cooking for about 1-2 minutes.
  2. Slowly pour in the white wine, stirring constantly, and let it simmer for 2-3 minutes to cook off the alcohol.
  3. Add the broth, thyme sprigs, bay leaf, and Worcestershire sauce. Bring the mixture to a boil, then reduce the heat to low and let it simmer for 25-30 minutes, allowing the flavors to meld together.

Step 4: Prepare the Topping

  1. Preheat your oven’s broiler.
  2. Place the baguette slices on a baking sheet and toast them under the broiler for 1-2 minutes per side, or until golden brown.

Step 5: Assemble and Serve

  1. Ladle the hot soup into oven-safe bowls and place a toasted baguette slice on top of each bowl.
  2. Sprinkle a generous amount of grated Gruyère cheese over each slice of bread.
  3. Place the bowls on a baking sheet and broil for 2-3 minutes, or until the cheese is melted, bubbly, and golden brown.
  4. Carefully remove from the oven, let cool slightly, and serve hot.

Cooking Notes

  • Onion Peeling Tip: Blanching pearl onions makes peeling much easier and quicker, saving you time and effort.
  • Wine Substitute: If you prefer not to use wine, you can substitute it with an equal amount of additional broth, but the wine adds a lovely depth of flavor to the soup.
  • Cheese: Gruyère is the traditional cheese used for French onion soup, but you can use Swiss or even a mix of mozzarella and Parmesan for a similar melty, bubbly topping.

Variations

Vegetarian French Pearl Onion Soup

  • Use vegetable broth instead of beef broth for a vegetarian version of this soup that still has a rich and satisfying flavor.

Mushroom Pearl Onion Soup

  • Add 1 cup of sliced mushrooms when caramelizing the onions for an extra layer of earthy flavor that pairs beautifully with the sweetness of the pearl onions.

Spicy French Pearl Onion Soup

  • Add 1/2 teaspoon of red pepper flakes when adding the garlic for a subtle heat that contrasts with the sweet, caramelized onions.
