Remove lid from Instant Pot. Add oats and water, and stir. (You may opt to add spices, sweetner, and/or chopped or dried fruit at this point. I like to keep mine plain to use in both sweet and savory meals throughout the week.)
Replace lid. Set pot to Manual High Pressure for 10 minutes.
When the timer goes off, allow the steam to release naturally.
When all the steam is released, carefully remove lid and stir oats. They will appear watery but will thicken upon standing.
Spoon out serving and add whatever toppings you prefer. Enjoy!
