2tablespoonsfresh thyme leavesplus more for garnish
Salt and freshly ground black pepper
1/4cupheavy creamor more to taste
Instructions
Place the dried mushrooms in a bowl and add the warm water. Allow to stand for a minimum of 30 minutes to rehydrate the mushrooms, then transfer them to a cutting board using a slotted spoon, chop roughly and set aside.
Add enough broth to the soaking liquid to equal 4 cups, then stir in the sherry and set aside.
Heat the olive oil over medium heat and add the carrot and celery. Sauté for about 4 minutes until softened, then add the onion.
Continue cooking until the onion is soft and translucent, 3 minutes longer, then add the garlic and cook until fragrant, 1 minute more.
Stir in the rehydrated mushrooms and cook for an additional minute. Add the sliced fresh mushrooms (keep a few for garnish), reserved broth mixture, and fresh thyme.
Simmer slowly for 45 minutes, tasting and seasoning with salt and pepper once or twice during the cooking.
Using a hand blender (or conventional blender) purée the soup to a smooth consistency.
Stir in the cream, taste and adjust the seasoning if needed.
Ladle into bowls and garnish with a mushroom slice and sprig of thyme.
Notes
We used dried porcini mushrooms in our soup, but you can use any type you like. If you don't want to use dried mushrooms, include another 8 ounces of fresh mushrooms and replace the water with extra broth.
