Combine the steel cut oats and water in the bowl of a 6-quart Instant Pot and stir. (If using a smaller machine, I recommend cutting the recipe ingredients in half.)

Secure the lid and turn the steam release valve at the top to sealing.

Press the Manual or Pressure Cook button, then set the cook time to 6 minutes on high pressure. The Instant Pot will read "ON" as it comes to pressure, approximately 10 minutes.

When the oats are finished cooking, allow the pressure to naturally release, approximately 15 minutes.

Once the pressure has released, turn the steam release valve to "venting" to release any remaining pressure.

Carefully remove the lid and stir the oats to incorporate any water that is sitting on the top. Your oats may seem a little loose but will thicken up as they sit.

Serve warm with your favorite toppings, if desired.

Leftover oats can be stored in individual containers in the fridge for up to a week or frozen for up to 2 months.
