Instant Pot Oatmeal is the ultimate breakfast--fast, hands-off, and completely customizable! In less than 20 minutes, you can enjoy creamy, perfectly cooked rolled oats, prepared effortlessly right in your Instant Pot.
Effortless Instant Pot Oatmeal
While waking up to a slow cooker full of steel-cut oats is dreamy, and grabbing a jar of overnight oatmeal from the refrigerator is a great start to a hot summer morning, Instant Pot Oatmeal is my hands-down favorite way to effortlessly prepare oatmeal!
It takes minutes to prepare, is always super creamy, and packs in a nice serving of whole grains and fiber into breakfast. Serve it with any toppings you like for a wholesome breakfast you will never tire of eating.

How to Make Instant Pot Oatmeal
If you are unfamiliar with cooking in an Instant Pot or the functions of your Instant Pot, be sure to start with my guide for using an Instant Pot for the best results on this and future recipes. You will find the full recipe in detail in the recipe card below.
- Pour in 1.5 cups of cold tap water into the inner pot of an Instant Pot and add a metal trivet.
- In a stainless steel bowl or deep 7x4-inch cake pan (I find the cake pans easiest to find), combine the rolled oats with water and/or milk of choice. If desired, add in flaxseed, ground cinnamon, etc.
- Secure the lid on the Instant Pot, be sure the vent knob is pointed towards sealed, and set the cooking time using the Pressure Cook or Manual button to high pressure for following times:
- Old-Fashioned Rolled Oats: 3 minutes
- Quick-Cook Rolled Oats: 1 minute
- Once the cooking time has elapsed, let pressure release naturally for 10 minutes and then release any remaining pressure if needed by using a long utensil to knock the steam release knob from sealed to venting--be sure to stand back to protect your face.
- Open the Instant Pot and serve your oatmeal as desired.
Kristen's Key Tips
- Use Rolled Oats, Not Steel Cut Oats. If you have steel-cut oats follow my recipe for Instant Pot Steel Cut Oats.
- Cook Pot-In Pot. Use a stainless steel bowl or cake pan for easy clean-up and allows you the ability to add milk or non-dairy milk to your oats without causing a burn notice.
- Flavor it Your Way! Add flaxseed for fiber, protein powder, top with fresh fruit, stir in nut butter--the options are endless!
Not Adding Dairy?
Skip the Pot-in-Pot Method
If you are not adding dairy or non-dairy milk, you can prepare oatmeal directly in the inner pot.
- Combine 2 cups of rolled oats with 3 cups of water directly inside the inner pot.
- Cook on HIGH pressure for 1 minute for old-fashioned rolled oats or 0 minutes for quick-cooking rolled oats.
- Let pressure release naturally for 10 minutes, then serve as desired.
Ideas for Toppings
One of the main reasons I love to make a big batch of plain Instant Pot Oatmeal is so that each person can flavor/top their oatmeal exactly as they desire. Here are a few of my favorite Instant Pot Oatmeal variations.
- Maple Syrup & Berries: Drizzle oatmeal with maple syrup and top with any berries you like. Add nuts if desired.
- Peanut Butter & Banana: Top oatmeal with sliced banana and drizzle with peanut butter.
- Almond Joy: Top oatmeal with mini chocolate chips, shredded coconut, and toasted almonds.
- Pumpkin Pie: Mix in 2-3 tablespoons pumpkin puree, ½ tablespoon maple syrup, and ½ teaspoon of pumpkin pie spice.
- Raisin Nut: Top oatmeal with a dash of cinnamon and 1-2 tablespoons each of raisins and chopped walnuts.
- Apple Pie: Top with freshly chopped apple, cinnamon, and a drizzle of honey or maple syrup.
- Savory: Top oatmeal with cooked breakfast sausage or baked bacon, shredded cheese, and/or a fried egg.
- Berries and Cream: Top oatmeal with ¼ cup of fresh berries and up to ½ cup of yogurt.
Storage Instructions
- Refrigerate: Allow the oatmeal to cool slightly and store in the refrigerator in an airtight container for up to 5 days.
- Reheat: Reheat individual servings in a heat-safe bowl in 60-second intervals in the microwave.
FAQs on Instant Pot Oatmeal
For oats to cook properly, you need to use a ratio of 3:2 liquid to oats. When cooking oats in your instant pot, much like rice, you will NOT need as much liquid as you do when cooking on the stovetop. This is because, when you cook oats on the stove, some of the liquid is evaporated, but in the pressure cooker, no liquid is evaporated.
NO! When I first wrote this post, I suggested using an oven-safe glass dish, since then Pyrex has come out to say that their dishes are not safe in the Instant Pot, therefore I no longer recommend using any glass heat-safe dish. Stainless steel is the way to go to be safe!

Ingredients
- 2 cups rolled oats
- 1 cup water, plus water for inside inner pot
- 2 cups milk, any variety
- 1 tablespoon flaxseed, optional
Instructions
- Pour in 1-½ cups of cold tap water into the inner pot and add a metal trivet.
- Inside a 7-cup heat-safe bowl or 7x4-inch cake pan, mix together the 2 cups of rolled oats with 1 cup water, 2 cups milk of choice, and 1 tablespoon flaxseed, if using. Place the bowl or pan inside the inner pot on the trivet.
- Place the lid on the Instant pot and ensure the pressure valve is set to "sealed." To set the cooking time, hit Manual or Pressure Cook and set to cook on HIGH Pressure for 3 minutes for old-fashioned rolled oats and 1 minute for quick-cooking oats.
- Once the cooking time has elapsed, allow the pressure to naturally release for 10 minutes before carefully releasing any additional steam by using a wooden spoon to turn steam valve to vent.
- Remove the bowl carefully from the pressure cooker and then serve with desired toppings or allow to cool and store in fridge to reheat as needed.
Notes
- You need a total of 3 cups liquid to 2 cups oats for oats to cook properly. If you want your oats to be really loose, use an additional ½ cup of dairy or water.
- You can use all water or all dairy. In my experience all water is incredibly bland and using all dairy/non-dairy as your liquid doesn't result in oats breaking down into a creamy texture.
- It is important to note if you are using a high-fat dairy (like coconut cream or whole milk) you MUST use only half full-fat dairy products with half water so the fat in your dairy will not separate while cooking under pressure.

Im always frustrated with recipes that dont tell you the exact amount for ingredients. Ive never made oats and thats why i was looking up recipes. I dont like guess work. Even though you state 1 cup of water/milk you never stated how much oats. I guess i just move on to the next recipe.
Hi Heidi. Sorry for your frustration, but the amounts are listed in the recipe card.
No they're not. How many cups of oats???????
In the recipe card it states 2 cups of old fashioned oats 🙂
I've had such a hard time finding a recipe for old fashioned oatmeal in the instant pot without added other stuff. I really would love to have a bit more detail in this recipe. I don't want to use dairy - I see where you put one cup of water in the Instant pot, then the oatmeal in an added bowl - but how much water to go with the oatmeal? You say one cup, and then you say one cup of dairy. So if I don't want the dairy is it two cups of water? Is it one cup of oats to one cup of water or one cup of oats to two cups of water? Thanks!
Hi Summer. You need 3 cups liquid to 2 cups oats. If cooking pot in pot, mix that all together and then place into instant pot on trivet over 1 cup of cold water. If making right in the Instant Pot, just mix it all together and cook as instructed. Hope that helps.
Thanks for clarifying a bit! I am still sort of confused by what the recipe card says - it does not all match up or seem totally clear, but from your reply I guess I put 2 cups of old fashioned oats in the inner 7 cup bowl, and 1 cup of water. No dairy. All this on the trivet over one cup of water in the instant pot. Then I cook on pressure, high, for 8 minutes, let it naturally release for 5 minutes, then release pressure. Done. Will try this this morning!
Hi Summer. I am so sorry for your confusion. For every 2 cup oats, you need 3 cups liquid. So you need 2 cups oats, 1 cup water, 2 cups milk of your choice (or 3 cups water). Mix that together in a bowl. Place trivet inside inner pot. Pour in 1 cup cold water into pressure cooker and then place bowl on trivet. Then cook as directed. I hope that helps.
I appreciate reading the flavor suggestions to customize the completed oatmeal. I would like to point out that plant milks are NOT dairy, so there is no problem whatsoever using them in the Instant Pot. In fact, the oatmeal recipe in the Instant Pot recipe book includes plant milk. I have made this as well as many other hot cereal recipes with great success.
I used the pip method (uncovered) with 2 cups rolled oats, 1 cup water, and 2 cups milk and added raisins and cinnamon. I set it for 8 minutes HP and let it natural release for 9 minutes and my oats came out slighty undercooked. Any suggestions?
Hi Grace! If you like your oats super broken down, you may want to cook for 9 or 10 minutes in the future. Also, be sure to use cold water in the bottom of the of your pressure cooker! In fact if you used warm water for PIP, first start with using cold water and still cook for 8 minutes on high pressure.
I did not have a pot to use the PIP method so I followed her instructions for making this directly in the IP insert. Very minimal sticking which was easily scraped off. Zero burning. I like my oats a bit creamier so I added milk and butter after cooking. Very pleased how well it turned out, as well as, not having to babysit and stir during the cooking process. We currently live FT in our travel trailer so easy meals are a must. This recipe is a keeper!
Thank you for letting us know your modifications! I am so glad you enjoyed the oatmeal.
I just got a Mealthy Multipot and made oatmeal in the stainless steel pot but I added a couple tsp of butter to the water/nonfat milk as well as salt, brown sugar and dried cranberries. I didn’t have an issue with sticking but could be the butter and a bit too much liquid. It all turned out well even sitting in pot on warm for a couple hours.
Great to know! Some models are more prone to get burn warnings, so I try to create my recipes to prevent that from happening, regardless the model used.
I made a double recipe in my 8 quart with peaches. It was fast, almost effortless and delicious 😋. Thank you for the recipe.
YAY! I love fast and effortless meals myself--especially for school mornings! Enjoy!
