Marcia Kiesel’s luxuriously creamy soups are the perfect starters for Thanksgiving dinner because they can be made in advance, then reheated and garnished just before serving.
- 2 tablespoons unsalted butter
- 2 tablespoons extra virgin olive oil
- 1 large onion, coarsely chopped
- 1 quart low sodium vegetable broth
- 4 cups water
- 2 1⁄2 lbs parsnips, peeled and cut into 2-inch chunks
- 2 ounces thinly sliced prosciutto, cut into 1/4-inch-wide strips
- 1⁄2 cup heavy cream
- 1⁄2 cup milk
- 1 tablespoon thyme leaves
- salt & freshly ground black pepper
- 1.In a large pot, melt the butter in 1 tablespoon of the olive oil. Add the onion, cover and cook over low heat, stirring occasionally, until softened, about 5 minutes. Add the broth and water along with the parsnips and bring to a boil over high heat. Cover and simmer over low heat until the parsnips are tender, about 30 minutes.
- 2.Meanwhile, in a small skillet, heat the remaining 1 tablespoon of olive oil. Add the prosciutto and cook over moderately high heat, tossing, until crisp, about 30 seconds. Using a slotted spoon, transfer the prosciutto to a paper towel–lined plate to drain.
- 3.Working in batches, puree the soup in a blender until very smooth. Transfer the soup to a clean saucepan. Stir in the cream and milk and bring to a simmer over moderate heat, stirring a few times. Season the soup with salt and pepper and ladle into bowls. Garnish with the prosciutto and thyme leaves and serve.
