Japanese Rice Porridge with Sweet Potato

Jump to Recipe

Rice porridge, or ‘Okayu’, is a very basic Japanese comfort food made from rice and water, or tea in my home prefecture.

Although it’s a very simple dish, it’s so delicious and perfect to eat when you’re sick! I added purple sweet potato to this recipe, but it can also be eaten plain or with umeboshi (pickled plum).

Imogayu

Rice porridge (okayu) is often served to sick people, elderly people, or babies because it is very easy to digest and doesn’t require much chewing, so it’s a bit like soup. It’s also warm and soft so it’s just perfect. My daughter was recently sick and she asked me to make this and I had a few purple sweet potatoes so I thought I would add those too. It gives it a little something extra (please someone get that reference) and makes it a little less basic or boring.

Imogayu

In most of Japan, this dish is made from water and rice so it has much more of a clear, white colour. But in my prefecture, we make it with tea so it turns out a brownish colour. My father will only eat this version of okayu because it is what he has grown up eating. He really loves it and eats it at every meal. We call it ‘okaisan’ because of the difference in dialect, but it’s pretty much the same thing. There a lot of different things you can add to okayu, like sweet potato, mochi, or umeboshi, or you can just it eat plain. It tastes great either way! I hope you enjoy the recipe!

  1. Thank you very much Shihoko! My father has been very sick for a while – usually he goes days without eating, but he’s been able to eat okayu (he also likes it best with tea) and some small toppings on the side.

    I’m fond of it as well, after cooking it so many times!

    By the way – what prefecture are you from, if you don’t mind me asking?

    1. Hi Elise, Thank you for visiting and trying out my recipe. I am glad to know that your father liked it. I am from Wakayama Prefcture where Chagayu(tea rice) is most eaten 😀
