Add the water and oats to your Instant Pot. Put your lid on and make sure the vent is closed.
Plug it in and select the manual setting and set to cook on high pressure for 3 minutes.
The Instant Pot timer will begin counting down the time once it gets up to pressure.
Allow the pressure to release naturally. You’ll know when it’s ready because the round silver pressure gauge will drop down. This will take about 5 to 10 minutes.

Notes
You can use nondairy milk instead of water if you are NOT using the delay timer.
