What mushrooms to use for Instant Pot Cream of Mushroom Soup?

You can use any kind you like or have available. However, for enhanced flavor, we recommend going with cremini, shiitake, or porcini mushrooms. Also, you could use fresh or dried type. They are great in this recipe as they have a deep and rich texture. When combined with cream, they really stand out. 

In addition, they are pretty healthy and have plenty of vitamins and nutrients. For example, these mushrooms have a good source of vitamin D.

Should Instant Pot Cream of Mushroom Soup be served hot?

We enjoyed serving it warm. However, serving it chilled is also an option. It tastes great either way. During winter months, we prefer to serve it warm or hot, and when it comes to spring or summertime, we like to serve it cold.

How long will it last in the fridge?

Before storing, let it cool completely. Then, transfer the soup to an airtight container and ensure is properly sealed. It can be stored in the refrigerator for 3-4 days.

Can I freeze the soup?

Yes. This dish can be easily frozen. Simply allow it to cool completely. Then, transfer the dish to an airtight container or heavy-duty freezer bags, and freeze for up to 3 months. 

Allow it to thaw overnight prior to serving. Also, you can reheat it in the microwave or stovetop for a few minutes. To prevent the soup from curdling, stir well when reheating it.

Recipe Tips:

  • If you are not a fan of cream, you could substitute it with evaporated milk or regular milk (either full fat or 2% are fine).
  • For a spicier version, add some sliced jalapeno or red chili pepper flakes to the mix. 
  • Also, you can top it with some shredded parmesan or mozzarella cheese. 
  • Chicken broth can be substituted with vegetable broth for a vegetarian version.
  • Adding some herbs such as thyme will give the soup a nice aroma and flavor.
  • For a double batch, simply double the ingredients. You may consider using an 8-qt pressure cooker in that case. 
  • For a more deep umami flavor, you can add a bit of rice vinegar, to taste, at the end of the cooking process. 
  • Similarly, a bit of sherry can be added at the end for some extra taste and flavor.
  • In addition, use freshly minced garlic as the canned version will not taste the same.
  • To keep this recipe gluten-free and to avoid an extra step of creating a roux, we use a mix of cornstarch and cream to thicken it.
  • Keep in mind, that if you are looking for an even thicker, creamier texture, you can add a bit more of the cornstarch slurry. Simply mix two tablespoons of water with one of cornstarch until fully dissolve and add to the chowder. Repeat as needed and keep in mind that it will thicken more as it cools.

I haven't tried cream of mushroom soup as a meal, only as an ingredient in a dish. I would love to try this instead of using for a casserole! It looks so delicious.



Oh wow! That looks so good! I've never tried making my own cream of anything soup. I have to try this.

Erin | Dinners,Dishes and Dessert

Looks so perfect! Definitely a must try! This looks heavenly!



This recipe looks great, thank you for sharing! If I did want to make a roux, at what stage would I add it? I know what I would do on the stovetop, but I'm not sure if cooking it in a pressure cooker changes that.


After you pressure cook, put it on saute and add the roux.


Mary beth Burkosky

Definitely a five-star recipe! I made it exactly as stated and cooked it exactly as stated.  Absolutely fabulous. I cooked another 3 cups of mushrooms with butter and seasonings but didn’t add them directly to the already made soup. They were an addition for anyone wanting a little more cooked mushrooms. Ladle your soup and add additional mushrooms if desired. I also served with crusty garlic bread as suggested. It was a huge hit. Rave reviews from all and I loved it as well. Wouldn’t change a thing . This will definitely my go to recipe for homemade mushroom soup. I did blend a couple of cups in a blender and then re-added it to the soup. Absolutely great! Thank you.


Hi Mary, thank you for your feedback, and we are glad that you have enjoyed it!
