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.
