How to Make Cauliflower Soup in the Instant Pot
• Prep all of the ingredients and have them ready to go before cooking.
• Turn on the pot’s Sauté setting. When hot, add the oil and the onion. Cook, stirring occasionally, until the onion is soft.
• Add the garlic and stir. Cook, stirring frequently, for 30 seconds. Turn off the pot.
• Add the cauliflower florets, salt and pepper.
• Pour in the broth and add the carrot.
• Then stir in the bouillon.
• Close the lid and set the steam release knob to the Sealing position, if not self-sealing.
• Press the Pressure Cook/Manual button or dial, then the +/- button or dial to select 4 minutes cook time. High Pressure. The pot will take several minutes to come to pressure.
• When the cook cycle has finished, let the pot sit undisturbed for 15 minutes (15 minute natural pressure release). Then turn the steam release knob to the Venting position to quick release the remaining pressure. Turn off the pot.
• When the pin in the lid of the Instant Pot drops back down, open the lid and carefully stir the soup.
• Use an immersion blender or a potato masher to puree the soup (use caution with hot soup).
• Taste and adjust seasonings as desired. Garnish the top of the soup with whatever you like and serve.
Notes About this Instant Pot Soup
- Vegetable broth can be used.
- Heavy cream can be added after cooking, if desired.
- Cream cheese can be added before cooking for a richer result.
- Any cooked meat can be added after pureeing the soup; ham, bacon, chicken, etc.
What Can I Use in Place of Chicken Broth?
• A great option you can use is vegetable stock or broth for a vegan soup, or a vegetarian soup.
• Use a vegetable bouillon in place of chicken broth. The bouillon adds a lot of flavor.


What to Serve With This Soup
I like to keep it simple with a green salad and some Butter Dip Biscuits or Homemade Dinner Rolls.

What if I Don’t Have an Immersion Blender?
- You can use a regular blender, however, blend the soup in small batches as it can be dangerous to blend hot soup. I would let it cool quite a bit before blending, then heat it back up.
- A food processor can also be used, but take precautions as with a regular blender and hot liquid.
- You can use a potato masher, but it will not give the smoothness that blending will give the soup.
My Cauliflower Soup is Not Thick. What Happened?
The simple answer is not enough cauliflower and too much broth. To get a thicker consistency you will want to use a large head of cauliflower, mine usually weigh close to 3 pounds. I use 3 cups of liquid. Use less liquid with a small head of cauliflower.


How Can I Make This a More Creamy Soup?
• This soup has a creamy consistency without added cream, but if you want to make an Instant Pot creamy Cauliflower Soup, you can add the following:
• Add an 8 oz block of cream cheese before pressure cooking for a very creamy texture.
• Add 1 cup of Heavy Cream or coconut milk after pressure cooking.
• Stir in some shredded parmesan cheese or extra sharp cheddar cheese.
• Add a dollop of sour cream on top of your bowl of soup.
Storing Leftovers
You can store leftover Instant Pot Cauliflower Soup in an airtight container in the fridge for up to 5 days.


To Freeze This Soup
If you make this soup recipe without cheese, you can freeze it in an airtight container or freezer baggie for up to 3 months.


This is the best soup to make when you want a quick lunch or dinner. This is a family favorite soup in our house. I hope you like it as much as we do!
