Ingredients
Reserved mushroom stems
2 medium carrots, halved crosswise
1 bay leaf
5 peppercorns
4 sprigs of fresh thyme
1 pound assorted wild mushrooms (oysters, shiitakes, chanterelles, horn of plenty, porcini), cleaned and trimmed, stem ends reserved
1 red onion, 1/2 peeled and very thinly sliced, 1/2 coarsely chopped
Kosher salt and freshly ground black pepper
Preparation
Combine the broth ingredients with 2 quarts of cold water and bring to a boil. Reduce the heat to low and simmer 20 to 30 minutes. Meanwhile, slice the mushrooms into 1/4-inch strips.
Strain the broth. Add the onion to the broth and cook over low heat 3 to 5 minutes. Add the mushrooms and cook until they are tender, about 35 minutes.
Season to taste with salt and pepper. Ladle into shallow soup bowls and garnish with the thyme.
