Instant Pot Mushroom Barley Soup Recipe
I've been behind the slow cooker craze for years and from what I've heard, the Instant Pot is even better. So let's embrace it, okay? Anything to make our hectic lives even just a tiny bit easier, especially during back to school season and the holidays!
As much as I have loved my slow cooker over the years - and you should know this because I am constantly sharing slow cooker recipes with you guys - I really love the idea of an "Instant" dinner!
I think the Instant Pot is great for when you find yourself rushing home after a really long day and need to throw something together quickly for dinner. We can't eat take out all the time, right?

When do you add the barley?
Jenn
That would be helpful, wouldn't it? I am so sorry, thank you for pointing this out to me! You add the barley with the liquid. I just updated the post!
Leslie B
Thank you for this recipe. The soup is delicious and very easy to make.
My only issue was that there was not enough barley. Most likely I used too fine a barley. Easy fix - just boil some more barley and add it to the soup.
Perfect soup for a cold snowy day.
Laura Groome
This was delicious!
I added 2 bay leaves, a few leaves of fresh basil, spinach and kale to the pot. I took out the bay leaves and gave the soup a couple of short whirs with my immersion blender to thicken the soup, for my taste. This will be a staple for me!
Jenn
Sounds delicious!!!! I am so glad that you liked it so much!
Leslie Markiewicz
I also felt that it was not enough barley, so I added more uncooked barley after the soup cooked and it sat overnight(in fridge) and barley was fine. The picture looks like chicken stock was used instead of beef and I think next time I will use that. Also added wild mushrooms! Enjoyed the soup!

Does this freeze well?
Jenn
I would not suggest freezing this recipe. I think it would be mushy once defrosted.
