I absolutely love multi-purpose kitchen gadgets. If it doesn’t do more than one thing, I don’t want it in my kitchen taking up space! When I was asked to check out the latest Zojirushi rice cooker and see how it fared compared to my smaller rice cooker I knew i wanted to find more ways to test it out than just make rice. So I figured out how to make oatmeal in a rice cooker. And I have to say… I’m pretty impressed!

I already loved the Zojirushi brand and own one of their bread machines (all the way back from when my husband and I first got married) and the smaller rice cooker so including this larger capacity rice cooker into our home was perfect. The Zojirushi NL-AAC10 is a great multi-use rice cooker. And I’ve not only made rice and oatmeal in it, but I’ve also used it to steam things as well. Hello delicious dumplings and pot stickers!

Making oatmeal in a rice cooker is a piece of cake! As simple as dumping the ingredients in, adjusting the settings for porridge, and letting it cook. The rice cooker does all of the work. Wait… did I just give that all away in the beginning of the post? Well let me just show you the pretty pictures and talk about this awesome machine.

Aided by microcomputer technology, this category of rice cooker takes having rice on your menu from “occasional” to “serious”. Basically, the microchip does all the thinking for you, as far as adjusting cooking times and temperatures according to the type of rice you are cooking, and timing the pre-soaking of the raw grains and the final “wait” period during steaming.

That means you’re left with perfectly cooked food that every family member will love! No more burnt rice on the bottom. And it also means that you can make a delicious breakfast, lunch, or dinner using the same rice cooker.

How to Make Oatmeal in a Rice Cooker

1. Add 2 cups of old fashioned oats into the rice cooker*. Then add in 3 cups of water (or milk if you prefer a creamier oatmeal). Add any mix ins or flavors and stir together to combine. I added 1 diced apple, 1 teaspoon of ground cinnamon, and a tablespoon of brown sugar.

*For this recipe I consulted my rice cooker’s manual to see if there was a minimum amount of oats I needed to use for this rice cooker. I also wanted to make sure I was using the correct amount of liquid. If you’re using steel cut oats, double check the manual to see what the minimum amount is as well as what the liquid level should be.

2. Using the menu button, set rice cooker to porridge setting (bottom right). Once the setting is selected, hit the start button. A melody should play letting you know that the rice cooker has started the cooking process. Sit back and relax as your food cooks.

3. When the rice cooker is done cooking the oatmeal it will play a melody again. Don’t worry if you aren’t immediately available – the rice cooker will go to the warm setting after it’s done cooking. When you’re ready to eat, open the lid carefully and scoop out your oatmeal.

  1. That looks absolutely delish!! I tried it once in a slow cooker overnight {one of those FB recommendations that everyone shares, probably without ever trying it} – – – BIG MISTAKE!!
    It was dried up and burnt by morning. So bad that I literally had to throw out my slow cooker. Happy that you’ve shared this works, trying this one next time!!

    • It works if you cook the oatmeal in a water bath. You put an inner glash dish with the oatmeal and then pour water around the dish up to the water line in the bowl and put the slow cooker on low.

  2. Now that is something I would have never thought to do. Looks great.

  3. I made oatmeal once in my crockpot with orange juice and some spices. It was delicious! I always have oatmeal in the house!

  4. Why have I never made oatmeal in my rice cooker before?? Must remedy — looks absolutely perfect!

  5. We have a rice cooker we haven’t used in AGES. This is a great way to get some more use out of it! Plus the recipe looks delish!

  6. Now I’m craving a big warm bowl of oatmeal 🙂 I love when a small kitchen appliance can be used for other uses. Thanks for sharing this cool tip.

  7. You’ve got a great idea here. I’d love to try this, but first, I need a new rice cooker. I’m married to an islander so a good rice cooker is important. I guess it’s we keep buying the cheap ones and need a rice cooker like this that will last. Thanks for sharing such a great idea.

  8. So I have a confession – I am a small appliance addict! I do not have a rice cooker and that particular small appliance was never even on my radar until now! This is perfect! That would make my mornings so much easier!!! Totally adding rice cooker to my “wish list” now!

  9. Wow! I never would have thought of that!

  10. I have to pin this. My rice cooker is collecting dust in one of the cupboards. 🙁

  11. I don’t have a rice cooker – and my kids love oatmeal and I usually dread making it! This may have to be a consideration for my next trip to BB&B

  12. The title should maybe specify which rice cooker since it doesn’t state how to cook in ANY rice cooker. I have an Aroma but it doesn’t have the Porridge setting.
