📋 Ingredients
Here are the ingredients (amounts are in the recipe card below).
The only ingredients in this recipe are Japanese sweet potatoes!
Satsumaimo
Or Japanese sweet potatoes are magenta in color and have a whitish inside, and the standard size is about 300g to 400g.
We find a variety of satsumaimo in a grocery store during fall to winter.
Not only is this potato best suited for baking, but it can also be cooked into a number of dishes such as tempura, miso soup, salad, simmered dish, and so on.
Varieties of Satsumaimo
There are many types of sweet potatoes in Japan, each with its own unique flavor!
The following are some of the most popular Satsumaimo:
- Beni azuma
- Silk sweet
- Annou imo
- Beni haruka
Beni azuma and Silk sweet are soft and flaky textures.
Annou imo and Beni haruka is gooey and much sweeter than other types.
If you can find variations in your local grocery store, just give it a try and see which one is your favorite!
My personal preference is Bani azuma or Silk sweet.
Beni haruka is too sweet to my taste so I always pick Beni azuma or Silk sweet for making Yakiimo.
🔪Instructions
Let me show you how to make it.
- Preheat the oven at 180C/356F
- Wash and dry the Japanese sweet potatoes
- Wrap them in foil
- Roast at 180C/356F for 60 minutes
That's it! It takes less than a minute to prepare, then all you need to do is wait!
There you go! When you open it, it looks like this and it's super hot!
Do not take them out of the oven immediately, but leave them in the oven for a while to cool down.
How to eat yakiimo
You can eat it either hot or cold! Hot yakiimo are delicious, but cold ones are also delicious.
After yakiimo cools down, open the foil, grab the yakiimo, divide it in half by hand and eat from the middle.
You can eat the skin (I always do), but if you don't like the texture, feel free to remove it.
And leave the edge because it's hard and tastes bitter, so you don't need to eat it.
Storage
After the yakiimo is completely cooled down, take off of its moisture, wrap it up tightly with cling wrap, and store it in the fridge or freezer.
It will last 5 days in the fridge, and one month in the freezer.
If you freeze it, try this method!
Leave frozen yakiimo at room temperature for five minutes and scoop it into your mouth, it will be creamy like ice cream. Enjoy!

I'm Portuguese, and roasted sweet potatoes are a common snack in Portugal, normally eaten cold, I still eat them all the time. I also love Japanese sweet potatoes, sweet and a wonderful texture, I usually eat the peel first and then enjoy the sweet inside, yummy.
