Combine the almond milk, water, cinnamon stick, salt and oats in the pressure cooker pot and stir.
2 cups rolled oats, 1/2 teaspoon salt, 1/2 teaspoon cinnamon or 1 cinnamon stick, 1 cup almond milk, 1 cup water, 2 cups steel cut oats, 1/2 teaspoon salt, 1/2 teaspoon cinnamon or 1 cinnamon stick, 1 cup almond milk, 2 cups water
Put the lid on the pressure cooker and set it for Manual, High Pressure, 3 minutes (4 minutes for steel cut oats). It will take the Instant Pot about 10 minutes to reach pressure.
Once the pressure cooker is done let it release pressure naturally for 5 minutes. Then release any remaining pressure manually or let it continue to naturally release until you are ready to eat.
fresh or dried fruit, sugar, nuts, milk
Notes
Don't substitute dairy milk for the almond milk, it is likely to burn.
I have made this in the 6 quart and 3 quart Instant Pot with excellent results. If you try another brand or size you might need to make modifications to the recipe.
