Add steel cut oats, and toast, stirring regularly, for 5 minutes.
2 cup steel cut oats
Stir in the water and milk. Using 2 cups of milk will give you thicker oats, and using 3 cups of milk will give you thinner oats.
3 cups water, 2 cups evaporated milk or nondairy milk
Cover and turn the vent at the top to sealing. Press the manual high pressure and adjust the cooking time to 10 minutes. Be sure that the pressure release valve is set to sealing.
After the Instant Pot has finished cooking, allow the pressure to naturally release for 20 minutes.
Turn the vent to the venting position to release any remaining pressure.
Unlock and remove the lid. Give the oats a good stir.
Serve topped with your favorite toppings and mix-ins.
Notes
Butter: I use salted butter in this recipe.
Oats: It's important to use steel cut oats, not rolled oats, in this recipe.
Milk: Evaporated milk doesn't curdle the way that dairy milk can.
