Add your prepped cauliflower, potato and onion to your Instant Pot*
Sprinkle with Salt and Pepper
Cover vegetables with chicken broth. Use as much as needed but not more than barely covering.
Put lid on Instant Pot and set to 8 mins. Because of the amount of liquid, it will take about 10-15 minutes for your IP to come up to pressure.
Once done, quick release steam.
Blend all the ingredients with an immersion blender. You can also blend it in batches and return to pot.
Set your IP to sauté. Add your cheese and stir until melted. Turn off IP.
Add cream. This really is to taste and preference. Some people don't add it at all, preferring a soupier-soup while others like the thick swirl of cream. It's really your choice!
Stir and enjoy :)
For an added burst of flavour, you can add chopped green onions and something crunchy - like bread crumbs or croutons - to the top.
