Ingredients in Mushroom Wild Rice Soup

This soup starts with a hearty helping of uncooked wild rice cooked in broth. You can use chicken broth or make it vegetarian with veggie broth. Aromatics like onion and garlic are added to give the soup a delicious savory flavor.

You’ll add chopped carrots and celery, sliced mushrooms, and leafy green kale to pack this easy mushroom soup with protein and essential vitamins.

The soup gets spiced with the earthy flavors of thyme, rosemary, and bay leaves, and is then finished with a creamy roux to bring it all together.

How to Make Mushroom Wild Rice Soup?

This is the easiest soup to make. The main active time in this recipe is chopping the vegetables.

  • First, add the wild rice, broth, garlic, onion, celery, carrots, mushrooms, and spices to your pressure cooker.
  • Close the lid and make sure it’s set to “sealing”, then turn on the “soup” mode and cook for 30 minutes.

  • When the ingredients have cooked for 30 minutes, allow a natural pressure release. Add the kale leaves and stir them in.
  • On your stovetop, melt butter in a saucepan and add some flour to make a roux. Stir until the flour is cooked, then add milk.
  • Continue to stir and cook the mixture until it is thickened and creamy.

Tips for cooking Mushroom Wild Rice Soup in the Instant Pot

  • Always allow a natural pressure release. It takes longer to cook wild rice than other varieties of rice, so the extra time will allow the rice to soften to the perfect consistency.
  • Be sure to discard the bay leaves after the pressure cooking is finished. Bay leaves are great for adding potent flavor to soups, but they aren’t too pleasant to eat whole.
  • I like to have Better Than Bouillon base to make broth. It’s great to have on hand when you need broth or stock in a pinch!

Do you have to soak wild rice before cooking?

For home cooks who serve rice often, you may think it’s counterproductive to not soak the rice before cooking. While it’s true that soaking wild rice overnight will cut down on cooking time, that’s not necessary when cooking it in a pressure cooker.

Let the Instant Pot do the work for you! A pressure cooker steams wild rice to the ideal texture for this mushroom soup.

How long does it take to cook wild rice?

30 minutes of cooking and a natural pressure release is all you need to get the wild rice to the perfect consistency for this simple wild rice & mushroom soup.

You can also make this mushroom soup in a crockpot. Simply place all of the ingredients except for the butter, flour, and milk into your crockpot and cook on high for 2-3 hours.

Then, follow the instructions for making the roux on the stovetop. Add the thickened cream to your crockpot, stir to combine everything, then serve. It’s that simple!

How do you know when wild rice is cooked?

Wild rice should have a tender texture with a little bit of a bite (think al dente, like pasta) when cooked.

You’ll know the rice is cooked when it’s no longer hard or chewy, and some of the kernels have started to burst open. At that point it’s ready for you to enjoy!

Can you freeze this homemade soup?

While it may be tempting to stock your freezer with cooked soups for convenience, soups with cooked pasta and rice don’t freeze as well. Upon reheating, you’ll find that the pasta and rice has expanded and soaked up most of the liquid in the soup.

But don’t despair! You can make soup freezer packs to save some time and prepare ahead.

To freeze this creamy Mushroom & Wild Rice Soup, prepare all of the ingredients, (minus the roux ingredients) then place them, uncooked, into a large freezer bag. Squeeze out any excess air and label the bag with the contents and date.

When you’re ready to cook the soup, place the contents of the freezer bag into your pressure cooker and follow the cooking instructions as written. In no time at all you’ll have a delicious Instant Pot Mushroom Wild Rice Soup on the table and ready to devour!

  1. Hello Meeta,
    Thank you for the recipe. I tried it yesterday. The taste is really good, but my soup was very thick. For the cup measurement, I used the standard cup. Is that the right cup I used, or should I use an instant pot cup for measuring the ingredients?

    1. Hi Sri – I do use the standard cup size, but this soup thickens a lot as it cools. So feel free to add an extra cup of broth or reduce the amount of wild rice to 3/4 cup to get the right consistency.

  2. Wonderful soup! I made minor adjustments for my family. Used only 1/2 cup of wild rice and put in about a cup of already cooked rice at the end. Never added the roux or any cream. Kept it a broth. Also put in some black eyed peas. Will be making it again.

    1. Hi Charlie – If you have pre-cooked chicken, I would suggest adding it after pressure cooking is done. Otherwise, you can cook on soup mode for 20 minutes, open the instant pot, add the chicken pieces (small 1/2 inch), and cook for another 8-10 minutes. Glad you liked the soup!

  3. Tasty soup, but the cooking time is too long resulting in really mushy carrots and celery. My wild rice package says to cook the rice in an instant pot for 20 minutes. I’ll try that next time.

    1. Judith, at the bottom of each email this is an unsubscribe word to click. It will take you to the unsubscribe page. Peace be to you.

    2. Hi Judith – I have unsubscribed you from emails. As Barbara mentioned, I always include an option to Unsubscribe at the end of every email. Thanks!

  4. I would like to do that, too, and wondering if it’ll all fit into my crockpot. I also wonder if the cook time increases as well.

  5. We love this recipe! I am planning to make it for christmas, but would like to double the recipe- is that possible? Or should I just make 2 separate single batches?

    1. Hi Mary – You can substitute quinoa in this soup. However I would suggest to only pressure cook for just 6 minutes, so the quinoa is not overcooked. Would love to hear how it turns out!
