Our garden potato towers and potato barrels gave us a good load of spuds to use up this winter. We grew mostly white and red potato and a few purple potatoes too.

Our cauliflower crop was pretty minor this year so we purchased a medium head to add to this dinner. Potatoes and cauliflower are great together with the cheese and bacon.

After I cracked my third slow cooker in less than two years it became clear I needed a different kitchen tool for slow cooking. The Instant Pot is it! It has a stainless steel cooking pot and seven different function keys. I do so much with this pot.

And look what a great cauliflower soup recipe it made in very little time.

Cauliflower is a fantastic vegetable. It’s very healthy for you. It’s very popular as a potato substitute in recipes to lower carbs. This recipe is not low carb because it has potatoes. You can choose a lower starch variety of potato to help with that.

Cauliflower is replacing a good amount the potatoes in this potato and cauliflower soup. So it is lower carb than potato soup. Cauliflower cheese soup with potatoes. The cauliflower adds loads of excellent nutrients and fiber to this soup. And it tastes good too.

Use a bacon substitute if you need to reduce your sodium. Bacon is very high in sodium. That will bring the sodium level in this soup way down.

Instant Pot Cheesy Cauliflower Potato Soup Recipe

This is not a really thick potato soup with a bit of cauliflower, it’s more of a cheesy cauliflower soup with potatoes.

Some of our readers have made this instant pot cheesy cauliflower soup expecting a more robust consistency. Here are some suggestions for you to try if you want to change the texture.

If you prefer a thicker soup

  1. Add more potatoes if you have room in your pot.
  2. Use a drier variety of potato like russets. We prefer the whites and reds which are lower in starch and make a thinner soup.
  3. You may also thicken this soup with a homemade roux after you open the pot. After stirring it if you want a thicker consistency:
    1. Set the pot to SAUTÈ function.
    2. In a small bowl add 2 tablespoons flour or cornstarch to 1/2 cup of cold water. Whisk it and then stir it into your soup.
    3. Bring the soup to a boil. Stir it until you like the soup consistency and then serve. 

You may serve this soup either very chunky, or blended into a creamy texture

  1. Simply use a hand held potato masher to achieve the rougher textured soup.
  2. For a smooth texture use an immersion blender to blend the texture.

This soup looks very inviting. I noticed that once you cook all the bacon and remove it for later, it says ABSOLUTELY NOTHING about draining the grease from the pan. Am I to believe that you kept all that grease in the soup?

Thanks for pointing this out. I'll add the draining process into the recipe. I hope you let us know how you like it. Have a great day!

I made this tonight and followed your recipe. It was absolutely delicious! My whole family including a 4yr old and 1yr old devoured thier bowls. Really easy and all the ingredients in had already on hand! Thank you!

This was WAY too thin and not at all what I was expecting. I would use half the liquid next time. Please change the recipe, as it looks nothing like the picture when done.


Monday 11th of February 2019

Hi Karin, Feel free to thicken the soup next time if you prefer. The picture was taken of the soup in this recipe exactly as this recipe specifies. I created this soup and this is how it should look when finished.

It's not meant to be a really thick soup. I hope you tweak this recipe to make it your own. That's the beauty of homemade food. Thanks so much for offering your feedback and experience with this recipe. Have a great day!

I'm making this recipe now, but have a few observations and questions. In Step 1, what do you adjust the saute function to? Normal? More? For Step 3, you first need to cancel the saute function before pressing Manual or Pressure Cook (on newer models). Lastly, it isn't mention when you add the pepper, which is listed in the ingredients. I'm going to add it at the end, after cooking. Thank you for posting the recipe. It sounds delicious.

Hi Elizabeth, Thanks for pointing out the details I missed when describing the steps in this recipe. I 'll go back into the post soon and clear up the recipe card. I hope you enjoy the soup!
