Ingredients
1/2 pound smoked bacon, cut in 1/2" pieces
3 pounds onions, thinly sliced; see notes
2 tablespoons fresh thyme, picked
8 cups beef stock
1/2 cup dry vermouth or white wine
1 tablespoon coarse salt
black pepper
6 slices white country-style bread, sliced 1/2" thick
1 tablespoon dry sherry
6 ounces Gruyere cheese, thinly sliced
6 sprigs fresh thyme, for garnish
In a heavy large pot over medium heat, saute bacon until fat is rendered and bacon is crispy, about 5 to 6 minutes. Transfer bacon to a paper towel to drain. Set aside.
Saute onions and thyme in remaining bacon fat in pan until well caramelized, stirring occasionally, about 25 to 30 minutes. Deglaze with vermouth, and cook about 1 minute.
Add stock and salt and pepper to taste. Bring to a boil, reduce heat and simmer for 30 minutes.
Meanwhile, make croutons by toasting bread slices under broiler or in toaster, until golden.
Heat broiler. Add 1/2 teaspoon sherry and one crouton to each soup bowl. Sprinkle each crouton with 2 tablespoons of the reserved bacon. Ladle soup into bowls, top with Gruyere and place on a baking pan. Transfer to oven, and broil until cheese is melted and bubbly, about 2 to 3 minutes. Garnish with thyme sprigs.
Onions: Use red, white, and yellow, making sure one onion is of a sweet variety, such as Vidalia or Maui
