Start by rinsing your groats under cool, clean water. This removes any dust that has built up in storage.
Add 2 cups of uncooked groats and 3.5 cups of water into the pot of the pressure cooker. Place the lid on and turn to make sure it is in the sealing position.
Using the "pressure cook" setting, cook the oat groats on high pressure for 20 minutes. Allow the Instant Pot to natural pressure release for 10 minutes.
Release any remaining pressure by holding down the pressure release knob (I recommend using a hot pad to do this so you don't get steam burned).
Remove the lid. If there is any remaining liquid, drain it off and your oat groats are ready to be enjoyed!
