Yes, you can! To speed up the process of boiling potatoes, you can certainly use a pressure cooker or Instant Pot. Place potatoes in your Instant Pot with water, and a good pinch of salt. Allow the pressure cooker to come to high pressure and cook for 8 minutes, then use the quick release functionality. The potatoes should be fork tender. Drain potatoes, and continue on with the rest of the process. *Please note that other varieties of potatoes may have a longer cooking time.
