Ingredients Method Notes

Ingredients
  

  • 3 cups boiling water, divided
  • 2 cups dried porcini mushrooms (about 1½ ounces)
  • 3 tablespoons cornstarch
  • 1¾ teaspoons salt
  • 1½ teaspoons ground pepper, plus more for garnish
  • 1½ teaspoons dried thyme
  • ½ teaspoon dried tarragon
  • 2 tablespoons extra-virgin olive oil
  • 2 cups sliced shallots (about 8 ounces)
  • 2 tablespoons finely chopped garlic
  • ⅔ cup dry sherry
  • 3 pounds assorted fresh mushrooms (such as cremini, portobello, shiitake and button), sliced
  • 1½ cups heavy cream
  • Fresh thyme leaves for garnish (optional)

Method
 

  1. Prep the Dried Porcini: Pour 2 cups of boiling water over the dried porcini mushrooms. Let them soak for 20 minutes. Drain and strain the broth through a cheesecloth-lined colander, then combine the broth with cornstarch, salt, pepper, thyme, tarragon, and 1 cup boiling water.
  2. Sauté the Aromatics: Heat olive oil in a medium skillet. Sauté shallots and garlic for about 4-5 minutes until softened. Deglaze with sherry, letting it cook for 30 seconds before removing from heat.
  3. Combine Ingredients: In your slow cooker, add the soaked porcini mushrooms, broth mixture, shallot mixture, and fresh mushrooms. Set it to High and cook for 4 hours until everything is tender.
  4. Blend and Finish: Blend 2 cups of the cooked soup until smooth, then return it to the slow cooker. Stir in the heavy cream and cook uncovered on High for 10 minutes to thicken slightly.
  5. Serve: Ladle into bowls, garnish with thyme and black pepper, and enjoy!
