Riesling Onion Soup with Herbed Croutons
The Riesling wines produced on the Mendocino coast of California are light but full flavored, and they have a pure, buttery aftertaste that pairs nicely with the onions, leeks, tarragon and fontina cheese in this recipe. Avoid Rieslings labeled "late harvest" as they are too sweet for this soup. When serving the soup, pour a dry Riesling alongside.
- 3 Tbs. unsalted butter
- 4 large yellow onions, about 2 lb. total, thinly
- 2 leeks, including pale green tops, sliced
- 1 garlic clove, chopped
- 2 Tbs. fresh tarragon leaves, chopped
- 3 Tbs. all-purpose flour
- 2 cups Riesling
- 6 cups reduced-sodium chicken stock
- Coarse salt and freshly ground pepper, to taste
For the herbed croutons:
- 1/2 baguette, thinly sliced
- 2 Tbs. olive oil
- 2 Tbs. unsalted butter, melted
- 2 Tbs. chopped mixed fresh herbs, such as
tarragon, rosemary, thyme and flat-leaf
parsley, in any combination
- 1/2 lb. Italian fontina cheese, cut into
To make the herbed croutons, preheat an oven to 300°F.
Arrange the baguette slices in a single layer on a rimmed baking sheet. In a small bowl, stir together the olive oil, butter and herbs. Lightly coat each bread slice on both sides with the oil mixture. Toast the bread in the oven, turning occasionally, until crisp and golden brown, 15 to 20 minutes. Remove from the oven and set aside. (The croutons can be made up to 24 hours in advance and stored, tightly covered, at room temperature.)
Preheat a broiler.
Arrange individual ovenproof bowls on a baking sheet and ladle the soup into the bowls. Top each serving with 2 or 3 croutons and an equal amount of the cheese. Place the baking sheet under the broiler 7 inches from the heat source and broil until the cheese melts, about 1 minute. Remove from the broiler and serve immediately. Serves 6.
