Ingredients
- 1 ounce dried porcini mushrooms
- 1 cup hot water
- 2 tablespoons unsalted butter
- 2 large shallots, chopped
- 2 garlic cloves, minced
- 1 lb button mushroom, thinly sliced
- 4 cups beef broth (homemade or canned)
- 3 cups water
- 2 sprigs fresh thyme (or 1/2 t. dried)
- 2 tablespoons tomato paste
- 1/2 cup dry marsala wine or 1/2 cup sherry wine
- 3/4 cup heavy cream
- salt
- fresh ground black pepper
- 1/2 cup freshly grated parmigiano-reggiano cheese
Directions
-
Place dried porcini in a bowl with the hot water; let stand for 30 minutes.
-
Lift the porcini out of the water and squeeze them to extract more liquid.
-
If the water seems gritty, filter it through a piece of cheesecloth or a paper coffee filter.
-
Set the soaking liquid aside; chop the porcini.
-
In a skillet, melt the butter over medium heat.
-
Add in the shallots and cook, stirring occasionally, until tender and lightly golden, about 10 minutes.
-
Stir in the garlic and cook for 2 minutes; scrape the mixture into the slow cooker.
-
Add the porcini, soaking liquid, button mushrooms, broth, water, thyme, and tomato paste.
-
Cover and cook on LOW for 6-8 hours, or until the mushrooms are tender.
-
Just before serving, stir in the wine and cream; add salt and pepper to taste.
-
Ladle the soup into bowls, sprinkle with cheese and serve.
