Almost-Instant Mushroom Broth For A Rich Base Flavor

Recipe by Katie Mae

Makes 1 quart | Ready in 20 minutes | Stores 1 week in fridge


5 cups water
2 cups dried mushrooms
4 large garlic cloves, peeled and chopped
1 teaspoon black peppercorns


  1. Add all ingredients to the Instant Pot.
  2. Lock the lid in place, and close the steam valve. Turn the setting to manual and set the time to 10 minutes.
  3. Let the cooker come to pressure and cook. When the timer goes off, carefully turn the pressure valve release the pressure manually.
  4. Pour the liquid through a fine mesh strainer to catch the mushrooms and transfer the broth into a food-grade storage container. The broth is ready to use, or it can be cooled and store for later. The rehydrated mushrooms will still have a good flavor, so you can save those to add to another dish like a soup or casserole.


If it tastes flat, add a little lemon juice or rice or apple cider vinegar. For more depth of flavor and variety, play with adding more herbs or spices.

To do this on the stove top, add the ingredients to a pot, bring to a boil, and then simmer for 30 minutes.

Another option to rehydrate the mushrooms and create a broth is to soak the mushrooms in room temperature water for 2 hours. This is a gentler method that will create a milder broth, but the actual mushrooms will retain more of their flavor. Use this method if it’s important that the reconstituted mushrooms be rich in flavor more so than the broth.

One of the quickest ways to add rich flavor to a soup or stew is to start with a broth instead of water.

Bone broth—made from animal bones simmered in water—has been getting a lot of attention the last few years. It may provide nutrients, but that doesn’t make it healthy or humane.

A much more compassionate, and in my opinion, healthier and tastier alternative is mushroom broth!

Mushroom broth is certainly not new to the culinary world, but it is gained a lot more attention in the last couple years as more foodies are foraging for mushrooms, and vegan cooks are turning to mushrooms instead of meat for that rich umami taste and meaty texture.

To be truthful, I’m one of those crazy rare plant-based lovers who is not a fan of mushrooms.

Well, the taste I don’t mind, but the texture and aroma can make me cringe.

I know… I know! I’m working on this!

Afterall, they are key in Dr. Fuhrman’s recommendation of eating the G-BOMBS every day! In case you’re not familiar with this acronym, it stands for Greens, Beans, Onions, Mushrooms, Berries, and Seeds.

Not being a huge fan though, I wasn’t super excited about making a mushroom broth. I’ve actually had the dried mushrooms in my pantry for many weeks, maybe even a couple of months, just waiting to be used.

Well, today was the day, and boy was I surprised!!!

The flavor was outstanding!

It wasn’t a total shocker since I know that mushrooms, especially dried mushrooms, are one of the most abundant sources of umami!

And anyone who really knows me knows that I love umami-richness more than I love sweets!

Yet, when I used this mushroom broth to make my Plant-Strong Irish Stew, it still took my breath away!

This is exciting because now it’ll be easy for me get more of the benefits from mushrooms in my diet without the texture.

Plus, I’m thrilled that it’s such a quick and easy (aka KISS!) recipe because I think I’ll start making this every week to use in my cooking!

Now, I’m looking forward to your feedback. Do you like it as much as I do? Let me know, along with how you use it. I always like to hear about your kitchen creations!

    Yum. I am Irish and so excited to try this recipe Katie. Thank you!
    For St Paddy Day, Had a “Boxty” stuffed with mushrooms, asparagus carrots …with a “cream sauce” that had capers in It! I would love to veganize this recipe.

    cannot get dried mushrooms where i live. any ideas on making the broth with fresh mushrooms?

    1. KatieMae

      Although the dried are preferred because more flavor can be extracted, you can make a delicious broth with fresh mushrooms, too. I would up the amount of mushrooms to 3 cups when using fresh with 5 cups of water. You can keep the cooking time the same.

      Of course, another option is to be dried mushrooms online. Since they are dry, they pack and travel well.

    How many cups of mushrooms do you get in a 1 lb. bag of dried mushrooms? Just looked them up on Amazon & they’re kind of pricey. Do you have a particular brand that you use? Where do you purchase them?

    1. KatieMae

      It varies due to the size of the mushrooms and how tightly they’re packed but you can think about 1 cup is 1 oz. Thus, this recipe would call for 2 oz of dried mushrooms. They can be expensive at first glance, but they weight so little that 1 lb will go further than you think. This recipe makes 1 quart which could be enough for just 1 soup, or it can be used throughout many dishes, like stir-fries and curries. You could easily make 2 quarts with this recipe, too, if you don’t mind a slighly milder flavor.

      Asian grocery stores usually carry a good variety of dried mushrooms and may be priced better.
