Mushroom Barley Soup

This is a great Instant Pot mushroom soup. I use white mushrooms and bella mushrooms. I find the duo of the two mushrooms really helps bring out tons of flavor.

What Is Pearl Barley

Pearl barley is what you will find most in the stores. It is the most common barley that is sold and used. Pearl barley has lost its outer husk, and bran layer and then is polished.

Hulled barley is the other type you can find that is a bit heartier and more nutritious.

How to Make

Step 1: Turn the Instant Pot to saute and add in your diced celery and your onions.

Step 2: Then you will turn your pressure cooker off. Pour in the chicken broth and deglaze the bottom of the pan.

Now add in your barley, dill, carrots, mushrooms, and potatoes.

Step 3: Place your lid on the Instant Pot and make sure the valve is set to sealing. Cook for 15 minutes high pressure followed by a natural release for 5 minutes.

Does This Recipe Double

Depending on the size of your Instant Pot it will depend if you can double this recipe. The biggest thing is to make sure you do not go over the max fill line.

If you go over the line, you will find your Instant Pot will not come to pressure.

Can I Add Meat Into This Mushroom Barley Soup

You could easily dice up and add in some ham or turkey into the soup. Or even some ground beef or stew meat could be a great add-in.

As the recipe is, it is a meatless barley mushroom soup. But feel free to add meat if you want. This would be great to use leftover holiday ham or turkey in.

What If I Can't Find Petite Purple Potatoes

Petite purple potatoes can be hard to find at times. If your supermarket doesn't have any in stock, go right ahead and reach for a yellow gold. Or any petite potato.

Or if you only have russets or Yukon gold potatoes, peel, and dice into bite-size pieces for the soup.

Does This Soup Freeze Well

Absolutely! If you are a fan of meal prepping, go right ahead and whip up a batch and freeze leftovers.

I like to pour into single-serve containers and use that to meal prep for easy lunches in the week or busy weeknight dinners I can just reheat a soup at the end of a long hard day.

Just remember soups expand as they freeze, so make sure to leave room in the freezer-friendly container, or it will pop the lid off. You can also freeze in a sealable bag and lay flat to help limit the space used.
