THE RICH FLAVORS OF CLASSIC FRENCH ONION SOUP are especially comforting on a cold, gray day. The original recipe is lightened here by substituting chicken for beef stock. The croutons are the grand finale, and making them yourself is a snap; simply top sliced bread with cheese, bake on a baking sheet at 350°F. until golden brown, and cut into cubes. If possible, use homemade Chicken Stock (page 230) in this soup; the flavor is incomparable.
Cooks' Note
If your skillet is not wide enough or deep enough to hold 6 cups liquid, transfer the onions to a medium stockpot set over medium-high heat before adding the stock.
