Instant Pot Oatmeal – no-stir, fluffiest oatmeal, cooked for 10 min in electric pressure cooker.
I eat oatmeal almost every day, in various shapes and form: classic way cooked on stovetop, baked in the oven or raw kept overnight in the fridge. A few years ago I had a little epiphany when I tried baked oatmeal for the first time. It was so good I couldn’t believe it.
Now something similar happened when I bought an Instant Pot (electric pressure cooker). The first dish I cooked in it was, of course, oatmeal. The result was astonishing – cooked oatmeal was so light and fluffy even though it was just cooked in milk without addition of any other ingredients.
Baked oatmeal is also fluffy in a way, but it contains eggs and baking powder. This recipe for pressure cooker oatmeal contains nothing but milk and rolled oats. Some people put a pinch of salt in their porridge, but I don’t do that. I like to put a knob of butter in it. It gives a nice taste and is healthy, too (helps releasing water-soluble vitamins from oats, like vitamin E). Of course, you can add sweeteners and/or spices like cinnamon, vanilla or any other one that you like.
The best of all is that you don’t need to stir your oatmeal at all – isn’t that fabulous?!
The first time I made this I used recipe from Hip Pressure Cooker website. What I especially like about it was that it is not cooked in the main pot, but it is cooked in a serving bowl or a mug placed on a trivet. This helps to prevent scorching and there is no need to clean the large pot. Plus, you can cook just one serving.
I happened to find stainless steel mixing bowl in my local store that fits perfectly into my Instant Pot. You can also use regular porcelain serving bowl or several ceramic mugs.
When cooked oatmeal cools down completely, it does become dense, so I suggest you serve it hot. Of course, it can be kept in the fridge until next day as any other type of oatmeal.
I can honestly tell you, once I tried this recipe, I never looked back!

- 2 cups milk (or 1 cup milk and 1 cup water)
- 1 cup rolled oats*
- OPTIONAL INGREDIENTS: a pinch of salt, a knob of butter, a dash of cinnamon, vanilla extract etc
-
Pour 2 cups water in a base of your Instant Pot (electric pressure cooker). If you use hot water, you will speed up the process.
-
Place a trivet in the pot and a heat-proof bowl on the trivet. Pour milk in the bowl. Add oatmeal and other ingredients that you're using and stir. Do not cover the bowl.
-
Close the lid of the Instant Pot. Set on "Manual" function for 10 minutes ("Porridge" function also works fine). Set the valve to "Sealing".
-
When cooking is over, press "Keep Warm/Cancel" button and wait for a pressure to drop in a natural way (natural release). It will take 10-15 minutes to cool down. Open the lid and serve your Instant Pot Oatmeal immediately.

*steel cut oats need to be cooked for 15 minutes; you need to use 3 cups liquid per 1 cup oats

Great way to cook steel oats the night before.
Are you using a dry measure cup for the oatmeal and liquid measure for the milk?
I use the same measuring cup for both the oatmeal and the milk.
Tried this AM for breakfast. Great recipe, as promised, oats tasted great and they seemed to be more fluffy or puffed up than stove top. Takes a bit longer but well worth it, also no pot to clean.
That was my exactly point! More fluffy or puffed up and definitely worth waiting for.
I followed this recipe to the letter. This was the BEST oatmeal EVER! Fluffy and exactly the right texture! Clean up was WAY better than using a pan! Thank you!
How long will this oatmeal stay good in the fridge? Could I make a big match and have some for the whole week?
batch* not match sorry lol
I kept it for about 3 days. I’ve heard that it can keep all week, but haven’t tried it myself.
