Steps
Before you start
- Measure all ingredients before starting—the Instant Pot cooks quickly and you won't have time to gather items mid-recipe.
- Make sure your Instant Pot is clean and the sealing ring is in place.
- Have toppings ready if desired (nuts, berries, cinnamon, honey, or yogurt).
Add ingredients to pot
- Pour the steel cut oats, whole milk, and water into the Instant Pot.
- Stir well to combine and prevent sticking to the bottom.
- Add the butter pieces, brown sugar, and salt.
- Stir again until the brown sugar is mostly dissolved and all ingredients are evenly distributed.

Tip: Stir well to prevent the oats from settling at the bottom and burning on the heating element.
Cook under pressure
- Close the Instant Pot lid and set the valve to "Sealing." Press the Pressure Cook or Manual button and set to high pressure for 10 minutes.
- The pot will take about 2 minutes to come to pressure before the timer begins counting down.

Ready when: The Instant Pot will beep when the time is complete.
Tip: Do not manually stir during cooking—the pressure method relies on undisturbed steam circulation.
Release pressure and rest
- When the cooking is complete, let the pressure release naturally for 5 minutes.
- Then carefully turn the valve to "Venting" to release any remaining steam.
- Lift the lid away from you to avoid the hot steam.

Ready when: Steam stops venting when the valve is fully released.
Tip: Natural release prevents the oats from becoming too thick or frothy from rapid depressurization.
Stir and adjust consistency
- Open the lid carefully and give the oatmeal a good stir with a wooden spoon.
- The mixture should be creamy and porridge-like.
- If it seems too thick, stir in a splash of milk (2 to 4 tablespoons at a time) until you reach your desired consistency.
- If it's too thin, let it rest for 1 to 2 minutes—carryover heat will thicken it slightly.

Ready when: Oatmeal flows slightly off the spoon but holds together when served.
Tip: Oatmeal continues to thicken as it sits, so it's better to start slightly looser than you like it.
Serve immediately
- Divide the hot oatmeal among four bowls and serve right away.
- Top with your choice of toppings: chopped nuts, fresh berries, a drizzle of honey, cinnamon, Greek yogurt, or additional butter.

Tip: Serve immediately while hot—steel cut oatmeal thickens significantly as it cools.
Good to know
Tips
- Steel cut oats are less processed than rolled or quick oats, so they take longer to cook but retain a pleasant chewiness and nutty flavor—the Instant Pot method cuts cooking time from 30 minutes on the stovetop to about 12 minutes under pressure.
- The ratio of liquid to oats (4 cups liquid to 1.5 cups oats) is key; too little liquid and the oats won't soften fully, too much and you'll have soup. If you prefer thicker or thinner oatmeal, adjust slightly on your next batch.
- Stir the oatmeal well after cooking but before serving—the oats settle and can separate from the liquid underneath if left to sit.
- Instant Pot models vary slightly; if your oatmeal seems undercooked after 10 minutes of pressure, do a quick release, stir, seal again, and add 2 to 3 minutes more pressure.
Storage & reheating
Store leftovers in an airtight container in the refrigerator for up to 4 days. To reheat, place in a saucepan over medium-low heat with 2 to 3 tablespoons of milk per serving, stirring frequently until warm and creamy (about 3 to 5 minutes). Alternatively, microwave in a bowl with a splash of milk for 1 to 2 minutes, stirring halfway through.
Substitutions
- whole milk → Half-and-half, heavy cream, or non-dairy milk (almond, oat, or coconut milk). Using non-dairy milk will result in a slightly less creamy texture; cream or half-and-half will be richer.
- packed light brown sugar → Maple syrup, honey, granulated sugar, or cane sugar. Use 2 to 3 tablespoons of liquid sweeteners (maple syrup or honey) instead of 1/3 cup sugar. Liquid sweeteners create a slightly thinner oatmeal.
- unsalted butter → Coconut oil or ghee. These add different flavors; ghee will taste more savory, coconut oil slightly tropical.
- steel cut oats → Rolled oats or quick oats. Rolled oats require only 5 minutes of pressure cooking; quick oats need just 3 minutes. The texture will be softer, not as chewy.
