Set your Instant Pot to Sauté and melt the butter. Add the steel cut oats and toast them, stirring frequently until fragrant, about 2 minutes. This optional step deepens the flavor and gives the oats a nice toasty, nutty taste. Press the keep warm/cancel button and add water/salt. Stir to combine.
Without toasting the oats
Add the steel cut oats, water and salt into the instant pot. Mix to combine. Alternatively, you can use a bit less water and add a big splash of milk (dairy or plant-based) to make the oatmeal a bit creamier. Lock the lid and set the valve to Sealing.
Cook on high pressure for 6 minutes. Once the cooking cycle is complete, allow the pressure to release naturally for about 10 to 15 minutes. This softens the oats creating a luxurious creamy texture. Then carefully release any remaining pressure.
Open the lid and stir the oats as some of the liquid may have stayed on top. The longer the oats sit, the more they will absorb any liquid. Serve with your favorite mix-ins and/or toppings.
Notes
Get the right oats: This recipe is made with steel cut oats, aka Irish oats or pinheads
Toasting the oats: This is an optional step that only takes about 2-3 minutes and adds a nice toasty, nutty flavor to the oats. You can use regular or vegan butter.
Water vs milk: Because we are pressure cooking oatmeal, make sure you use mostly water for this recipe. You can supplement some of the water with milk, but too much dairy may give you a "burnt error"
After pressure cooking: When you open the lid of the pressure cooker, you will see that there's liquid on top of the oats. (this is normal). Simply stir to combine.
Too runny?: If the oatmeal seems too runny for your taste, allow it to sit in the pot for 10-20 minutes. The oats will absorb the liquid.
Make oatmeal extra creamy: Add a healthy splash of milk, almond milk, cashew milk or oatmeal, str and allow the oats to absorb the liquid until you reach your desire consistency.
Storage: Cool and store in an airtight container in the refrigerator for 5-7 days.
Freeze. Cool and store in an airtight, freezer safe container for up to 3 months.
Instant Pot coming to pressure: Depending on the model, pressure cookers may take 8 to 15 minutes to come to pressure before the cooking timer starts. This time is not included in our calculations above.
