Ingredients

Soup

3 tablespoons unsalted butter
1 tablespoon extra virgin olive oil
2 pounds yellow onions, cut in half lengthwise and thinly sliced
Kosher salt and freshly ground pepper
4 cups butternut squash, diced
1 tablespoon unbleached all-purpose flour
1/2 cup dry sherry
4 cups Swanson Beef Stock
2 tsp. fresh chopped thyme

Toppings

1/2 French baguette, sliced on a bias into 3/4-inch thick pieces
4 cups grated gruyere cheese

Preparation

  1. Step 1

    In a large heavy-bottomed pot, melt the butter and oil over medium. Add the onions and season with a pinch of salt. Cook, stirring frequently, until the onions are soft and golden, about 30 minutes.

    Step 2

    Increase the heat to medium-high and add ¼ cup of the stock and the butternut squash. Using a wooden spoon, scrape up brown bits from bottom of the pan and continue to cook, stirring frequently until the onions are deep golden, about 10 minutes more.

    Step 3

    Sprinkle flour over onions and squash, and stir to coat. Pour sherry and stock into the pot and add thyme. Bring to a boil and reduce to a simmer. Cook, partially covered, until squash is tender, about 12 minutes. Season with salt and pepper.

    Step 4

    Preheat the oven to broil with a rack in the top third. Arrange the bread on a rimmed baking sheet and broil until golden on both sides, about 1 to 2 minutes per side.

    Step 5

    Line a rimmed baking sheet with foil and arrange four ovenproof bowls on the prepared baking sheet. Ladle the soup into the bowls and top each with 2 or 3 slices of toasted baguette and sprinkle with cheese. Broil until the cheese is melted and golden in spots, watching carefully as broilers vary in strength, about 5 minutes. Serve warm.
