Equipment

Ingredients
 

  • 2 tablespoon (30 ml) butter divided
  • 1/2 medium yellow onion diced
  • 1 clove garlic minced
  • 1/2 pound (227 g) cremini mushrooms sliced
  • 1/2 pound (227 g) white mushrooms sliced
  • 1/2 teaspoon (1 g) dried thyme
  • 3 cups (710 ml) vegetable stock
  • 3/4 teaspoon (3 g) salt
  • 1/4 teaspoon (0.5 g) ground black pepper
  • 3/4 cup (118 ml) heavy cream
  • 1 1/2 tablespoons (8 g) cornstarch
  • Parsley or thyme for garnish if desired

Instructions
 

  • Turn the Instant Pot on to saute mode. When hot, add half the butter. Once melted, saute the onion until softened, about 3 minutes. Add the garlic and saute for 30 seconds.
  • Add the remaining butter and mushrooms to the pot. Saute for about 5 minutes, stirring occasionally.
  • Add the thyme, stock, salt and pepper.
  • Secure the lid and set the vent to sealing (if necessary for your model).
  • Set to cook on high pressure for 4 minutes. When the time is up, allow a natural pressure release (about 10 minutes), then carefully remove the lid.
  • Use an immersion blender to partially blend the soup for about 10 seconds. If you want a chunkier soup, blend less. If you want a smoother soup, blend more.
  • Turn back on saute mode.
  • Mix the cornstarch into the heavy cream, then pour it into the pot and stir until the liquid is bubbling and thickens slightly.
  • Serve with fresh parsley or thyme for garnish, if desired.

Notes

  • Be cautious when blending the soup, as over blending can make it too smooth. Leaving a few small mushroom pieces can add texture.
  • When adding the cornstarch mixture, do it gradually. You may need more or less than the specified amount to achieve your desired consistency.
  • If you have any white wine on hand you can add a splash during the sautéing stage for extra flavor.
