Place a steamer basket in the inner pot. The water level should be below the steamer basket's level.
Add the broccoli to the steamer basket. Close the lid and pressure cook for 0 minutes * at High pressure. (If your Instant Pot doesn't have the option to pressure cook for 0 minutes, program it for 1 minute. As soon as the Instant Pot reaches pressure and the display changes from On to counting down from 1 minute, press Cancel.)
Once pressure cooking is complete, do a quick release of pressure (QR). Open the lid. [Read More: The Different Pressure Release Methods]
Carefully remove the steamer basket using silicone mitts.
