Chestnut Soup with Sourdough Sage CroutonsMatthew Hranek

Most chestnut soups are fairly substantial. We've made our version lighter and brothier to serve as a first course for a big meal. Chopped chestnuts mixed with tangy croutons add texture and extra layers of complexity.

Cooks' notes:

•Topping can be made 3 days ahead and cooled completely, then kept in an airtight container at room temperature. Reheat in 1 layer on a baking sheet in a 350°F oven until bread is crisp, 10 to 20 minutes.
•Soup, without Sherry, can be made 3 days ahead and cooled completely, uncovered, then chilled, covered. Reheat and stir in Sherry before serving.
