Slice off any hard ends. Slice the sprouts in half and place them in bowl of the Instant Pot.
Add 1 cup of water. Lock the lid of the Instant Pot. Place the pressure release handle (vent) in the “Sealing” position.
Cook on high pressure for 2 minutes: Press the Pressure Cook button, making sure the “High Pressure” setting is selected, and set the time. Note that it takes about 5 minutes for the pot to “preheat” and come up to pressure before it starts cooking. (During cooking, avoid touching the metal part of the lid.)
Quick release: Vent the remaining steam from the Instant Pot by moving the pressure release handle to “Venting”, covering your hand with a towel or hot pad. Never put your hands or face near the vent when releasing steam. Open the pressure cooker lid.
Drain the pot of the water. Stir in the butter, chives, kosher salt and fresh ground pepper. Then stir in cheese. Extra water will come off of the sprouts, so remove them with slotted spoon to a serving dish. Top with a little more Parmesan cheese and serve.
Notes
*Makes 4 small servings: it’s easy to double for bigger appetites or more people.
