Press CANCEL button on Instant Pot.Close the lid on the pot, and turn valve from VENTING to SEALING position.Set the pot to MANUAL/PRESSURE COOK (High Pressure) and set timer to 2 minutes.
When the instant pot beeps,Let the pressure release naturally for 5 minutes and then do a quick pressure release. Open the lid.
Blend (optional): At this point, you can blend some of the soup using a immersion blender until smooth.If you don’t have a immersion blender ,puree in a blender once slightly cooled. NOTE: I dint blend the soup since i have added small pieces of broccoli before pressure cooking and i like the soup to be chunky texture.
Select “Sauté” mode. Add in the milk and cheddar cheese.Stir for 2-3 minutes until the cheese is melted. Adjust the salt and pepper at this stage. Let the soup simmer for 2 minutes.
