Press SAUTE mode on Instant Pot. Add butter and once it’s hot add minced and saute for 30 seconds.
Add onion and saute till they turn translucent.
Add broccoli ,water and give a stir .
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 3 minutes.
When the instant pot beeps, let the pressure release naturally. Open the lid.
Add Spinach, cheese, milk, salt and pepper to taste, stir well.
Puree soup using a hand blender until smooth.If you don’t have a hand blender ,puree in a blender in batches once slightly cooled.
If you think soup is too thin ,you can add cornflour-water mixture into soup and boil for 2 minutes, this gives thick consistency.I like soup thin so did not add it.
Broccoli Spinach Soup is ready to serve.
