Ingredients

  • 5 tablespoons olive oil, divided
  • 2 tablespoons butter, softened, plus more, to taste, melted
  • 5 cups yellow onions, thinly sliced, plus 1/2 yellow onion, grated, divided
  • 1/2 teaspoon sugar
  • 1 teaspoon salt
  • 3 tablespoons flour
  • 6 cups beef stock, warm
  • 1/2 cup dry white wine, such as sauvignon blanc
  • 8 slices French bread, sliced 1-inch-thick
  • salt, to taste
  • pepper, to taste
  • 2 tablespoons Cognac
  • 3 cups Swiss cheese, grated, divided
  • 1 cup parmesan cheese, grated
  • chives, to taste, chopped, for garnish

Directions

Step 1 -Preheat the oven to 325 degrees F.

Step 2 -In a Dutch oven over medium-low heat, add 1 tablespoon of the oil and 2 tablespoons of the softened butter and heat until the butter is melted.

Step 3 -Add 5 cups of the sliced onions to the butter mixture and sauté until they are evenly coated with the butter mixture.

Step 4 -Increase the heat to medium. Stir the sugar and the salt into the onions and cook, stirring frequently, until they are caramelized and reduced.

Step 5 -Reduce the heat to medium low, then add the flour to the caramelized onions. Stir until a thick pasta forms, about 2-3 minutes.

Step 6 -Add 1 cup of the beef stock to the onion mixture and use a wooden spoon to loosen any of the browned bits from the bottom of the Dutch oven.

Step 7 -Stir the remaining beef stock and the wine into the onion mixture and let it simmer, about 30 minutes.

Step 8 -While the soup is simmering, place the bread slices on a baking sheet and evenly drizzle them with the remaining oil.

Step 9 -Bake the bread slices, about 15 minutes.

Step 10 -Flip the bread slices and bake, about 15 minutes.

Step 11 -Increase the oven temperature to 350 degrees F.

Step 12 -Add the salt, the pepper, the Cognac, the remaining grated onions, and 1/4 of the Swiss cheese to the soup mixture and stir to combine.

Step 13 -Evenly ladle the soup into eight ramekins and place them on a rimmed baking sheet.

Step 14 -Place 1 of the toasted bread slices in a single layer over each of the soup.

Step 15 -Evenly sprinkle the bread slices with the remaining Swiss and the parmesan. Note: Ensure all the edges of the bread are covered with the cheese to prevent burning.

Step 16 -Evenly drizzle each of the cheese layers with the extra melted butter.

Step 17 -Bake the soups until they are bubbly and golden, about 30 minutes.

Step 18 -Switch the oven to the broiler setting and broil the soups until all of the cheese has browned.

Step 19 -Transfer the baking sheet to a wire rack and let the soups cool slightly.

Step 20 -Serve the soups garnished with the chives.
