RECIPE WITH GROUND BEEF AND CREAM OF MUSHROOM SOUP RECIPES

Steps:

• Clean the mushrooms by wiping them with a dry paper towel. Don't wash them! Separate the stems, trim off any bad parts, and coarsely chop the stems. Slice the mushroom caps 1/4-inch thick and, if they are big, cut them into bite-sized pieces. Set aside. 
• To make the stock, heat the olive oil and 1 tablespoon of the butter in a large pot. Add the chopped mushroom stems, the onion, carrot, the sprig of thyme, 1 teaspoon salt, and 1/2 teaspoon pepper and cook over medium-low heat for 10 to 15 minutes, until the vegetables are soft. Add 6 cups water, bring to a boil, reduce the heat, and simmer uncovered for 30 minutes. Strain, reserving the liquid. You should have about 4 1/2 cups of stock. If not, add some water. 
• Meanwhile, in another large pot, heat the remaining 1/4 pound of butter and add the leeks. Cook over low heat for 15 to 20 minutes, until the leeks begin to brown. Add the sliced mushroom caps and cook for 10 minutes, or until they are browned and tender. Add the flour and cook for 1 minute. Add the white wine and stir for another minute, scraping the bottom of the pot. Add the mushroom stock, minced thyme leaves, 1 1/2 teaspoons salt, and 1 teaspoon pepper and bring to a boil. Reduce the heat and simmer for 15 minutes. Add the half-and-half, cream, and parsley, season with salt and pepper, to taste, and heat through but do not boil. Serve hot.

Steps:

• Place the dried mushrooms in a large bowl. Bring the broth to a boil and pour over the dried mushrooms. Set aside to rehydrate for about 20 minutes.
• Using a slotted spoon, remove the mushrooms and reserve the broth. Roughly chop the mushrooms.
• Heat the butter in a large pot over medium-high heat. Add the button and rehydrated mushrooms and cook, stirring occasionally, until soft and somewhat dry, about 6 minutes. Add the leek and shallot and cook, covered, stirring occasionally, until translucent, about 4 minutes. Stir in the flour and cook, stirring, for 2 minutes more.
• Pour in the reserved mushroom broth, taking care not to add any grit or dirt that may have fallen to the bottom of the boil, and bring to a boil while whisking constantly. Tie the parsley sprigs, fresh thyme, and bay leaf together with a piece of kitchen twine and add to the soup. Lower the heat and simmer for 10 minutes. Remove from the heat and allow to cool.
• Remove and discard the herb bundle. Working in batches, transfer the mixture to a blender and puree until smooth. Using a sieve over a large bowl, strain the mushroom puree. Return the puree to the pot and reheat over medium heat.
• Whisk the heavy cream, Madeira, and salt into the soup and season with pepper to taste. Divide among warm soup bowls and serve immediately.
