This instant pot soup features celery, garlic, onions, mushrooms, and wild rice. It’s a comfort food sure to keep you warm on a chilly Fall afternoon.

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.

Do you have to put the rice in it

John

Good Morning Mardi, that's a good question. No, yo don't have to put rice in the soup. Although, it would drop the cook time significantly. With the being said, if you're looking for a similar recipe without rice, then take a look at our easy mushroom soup. It's made in the Instant Pot as well and does not contain rice. Here's the link. https://www.berlyskitchen.com/instant-pot-easy-mushroom-soup/ I hope this information helps, have a lovely day :)

Hi! If I wanted to make this a little earlier, would it be good to make the IP part, and then later at dinner time heat it back up, make the roux, and combine? Or is it just good to do it all at once and reheat like you recommended? Thanks!

John

Good Morning Katie, that's a good question. Personally, I think it's up to you. Both methods should work; however, if you do it all at once and reheat the soup, make sure to do it over low heat. Otherwise, you could break the roux during the reheating process. I hope this information helps. Thank you for coming back to comment on and rate the recipe. Have a lovely day :)

Thanks so much, Kimberly! I will try that but of course I had one more question before I do... your step 3 indicates that I set the Instant Pot to "sealing." What does that do... is it the same thing as when I set my PC to high that it starts to seal and bring up pressure? So sorry I didn't include this question the first time. :(

Thanks again for responding -- can't wait to try this!

Hi Michelle!

No problem at all! On the Instant Pot, there is a valve at the top that can be turned to seal the pot or to release pressure. When you turn the pot on to cook, you have to manually turn the valve to "sealing," otherwise, the pot will never build pressure. Sounds like your pot may do it automatically, which is great! :)

I do not have an IP - an electric Breville PC. I have a low, medium, high setting so I'm wondering which setting to use. Is there a conversion of IP settings to those of us using a different electric PC? I would have given this 5 stars based on the ingredients. Would have loved this with conversion info so that I could actually taste the soup. :)

Kimberly

Hi Michelle! I've chatted with some others that have similar brands of electric pressure cookers, and they are supposed to be the same as the Instant Pot. We used the high setting, so I'm thinking it would probably be the same. Although, I can't say for sure because I haven't use the Breville brand. Thanks for the comment! That was a great question. :)

Where do you get wild rice? Do you just use a box of something like Uncle Bens and leave out the seasonings?

Good Morning Donna, that's an excellent question. We use Lundburg's wild rice blend. Here's an affiliate link to it on Amazon: https://amzn.to/2vEWOAp Be aware if you use this link and purchase it on Amazon (or any other Amazon product for a limited amount of time), we are compensated for that purchase. With that being said, it was also available at our local Walmart. So, you might be able to find it at your local grocery store. I hope this information helps. If have any other questions, feel free to contact us. Have a lovely Sunday, Donna!
