The last couple of days we’ve been getting hit with thunderstorms. Which is great because the showers have been keeping the temperatures nice and cool.

It’s a welcomed change after the last months of scorching heat. Furthermore, it’s a reminder that Fall is just around the corner for us here the United States.

Keeping that in mind, Kim and I decided to share her latest Instant Pot soup. As you can see form the photos, it’s a creamy vegetable dish loaded with everything you need to make a delicious soup.

Including the foundation of any great savory recipe, carrots, celery, and onion. The fabled trinity of gourmet cooking make this Instant Pot soup a must-try no matter your experience in the kitchen.

I could talk about it all day, but let’s just get down to business. As always, you can find tips for the recipe just above the recipe card.

How to Make Instant Pot Wild Rice Mushroom Soup:

First, start by placing all soup ingredients into the Instant Pot, making sure to pour the rice on top. If the rice is on the bottom, it will stick and burn.

The roux ingredients are not included in this step as it is prepared separately on your stove-top. Next, use a spoon or spatula to press down the rice so it’s submerged in the broth.

If you don’t submerge the rice, it will not cook properly in the Instant Pot. Remember, nobody likes poorly cooked rice.

The instant pot soup ingredients like chicken broth, onions, carrots, and celery.

After that, close the lid and set the Instant Pot to “Sealing.” Then, choose the manual pressure/pressure cook option setting for 35 minutes.

After the cook time is finished, allow the Instant Pot to complete a 10 minute natural release before opening the valve for a quick release.

We would not recommend using a quick release right away because this is high-starch dish that needs time to soak up the flavorful broth.

Also, if you use a quick release, there’s a chance the steam will spray a thick starchy liquid all over your kitchen. Not fun times to clean-up.

Now, while the soup cooks, make the roux. Melt the butter in a medium-sized saucepan, then add the flour.

Whisk constantly to incorporate the flour and make a smooth consistency. The longer the roux cooks, the darker in color it will become.

Additionally, the longer a roux cooks, the less “thickening power,” it has when mixed with the soup. Cook for about 5-7 minutes, just long enough to eliminate the raw flour taste.

To finish the roux, add the milk and whisk everything to combine all the ingredients. Once your done, remove the pan from the heat and set the roux aside.

Last, with the soup finished in the Instant Pot, carefully add the roux. Stir the instant pot soup to combine everything and remove the bay leaves and thyme stems.

The soup should thicken and have a creamy texture. That’s it, serve and enjoy!

Instant Pot Wild Rice and Mushroom Soup Tips:

  • Not feeling the roux, that’s fine, just make a corn starch slurry and use that to thicken the soup instead of the roux. However, the soup will not have the same color and texture.
  • The soup is really thick after it cools. It’s best to heat it over low heat over the stove and add some milk to thin it out.
  • Almond milk or coconut milk can be used to for a dairy free option.
