2 teaspoons
olive oil
3 medium shallots, finely chopped
1/4 cup dry Marsala wine
1 pound white mushrooms, finely chopped
1/2 pound fresh shiitake mushrooms, stems removed and reserved
and caps thinly sliced
1 teaspoon minced fresh thyme or 1/3 teaspoon dried
Salt and freshly ground pepper
2 1/2 cups fat-free chicken stock or defatted homemade chicken
stock
2 teaspoons minced fresh flat-leaf parsley
Heat 1 teaspoon of the oil in a heavy nonstick medium saucepan. Add the
shallots and cook over moderate heat, stirring, until slightly softened
but not browned, about 4 minutes. Add the Marsala and cook just until
evaporated, about 2 minutes.
Add the white mushrooms, shiitake stems, thyme, 1/2 teaspoon salt and
1/4 teaspoon pepper and cook over moderately high heat for 10 minutes,
stirring occasionally. Add the chicken stock and bring to a boil. Reduce
the heat to low, cover and simmer for 30 minutes. Strain the soup and
return it to the saucepan; you should have about 3 cups.
Heat the remaining 1 teaspoon oil in a large nonstick skillet. Add the
shiitake mushrooms and season with salt and pepper. Cook over moderate
heat, stirring occasionally, until softened and lightly browned, about
5 minutes.
Ladle the hot soup into shallow soup bowls and add the shiitakes. Garnish
with the parsley and serve.
