  2. Add the oil to you IP insert and press the sauté button.

  3. Add the carrots, celery and onions to the oil and saute until the onions are translucent.

  4. Now stir in the mushrooms and continue stirring until they are fully wilted and some of the liquid has come out of the mushroom.

  5. Now stir in the garlic and sauté for about 1 to 2 minutes, then stir in the dried thyme and top off with the salt. (Smells good right about now, right?)

  6. Next, stir in the barley, then the vegetable broth and finally the mushroom soup mix. (or ground, dried mushrooms. Whichever you prefer.)

  7. Close the lid, close the vent and press the "manual" button, adjusting the time to 20 minutes.

  8. When the cooking time is done, allow 10 minutes for a natural release, and then do a quick release for any remaining steam.

  9. Add any additional salt as needed and serve with some crusty garlic bread.


  11. In a large stock pot, warm your oil and then add the carrots, celery and onions. Sauté until the onions are translucent.

  12. Add in the mushrooms and cook for about 5 minutes, or until the liquid from the mushrooms has started to "grease" the pot a bit.

  13. Add in the thyme, salt and mushroom soup mix (or ground, dried mushrooms).

  14. Finally, add the broth and barley and cook to package directions for the barley.

  15. Add any additional salt you prefer to taste and serve up a nice, hot bowl of soup! (Don't forget to blow!)
