Japanese Sweet Potatoes

Japanese sweet potatoes, or satsumaimo, have reddish-brown skin and creamy yellow-white flesh. They are typically sweeter, firmer, and starchier than other varieties and hold their shape well during cooking. Their versatility makes them a staple for sweet and savory Japanese dishes.

The only ingredients in this recipe are Japanese sweet potatoes! Choose the one that is uniform and gross without any bumps. Depending on the variety, there are various thicknesses, but pick those with a plump appearance. Learn more about types of Japanese sweet potatoes here.

By the way, they differ from Japanese yams, which have a sticky, slimy inside.

Recipe Tips

  • Leave the sweet potatoes in the oven for another 15–20 minutes after baking. This cooling time helps bring out more sweetness.
  • Each type of Japanese sweet potato has its own unique taste and texture. Find out more in Types of Japanese Sweet Potatoes.
  • If you freeze yakiimo, it turns into a creamy, ice cream–like treat. Let it sit at room temperature for about five minutes, then scoop it up and enjoy the smooth, sweet texture.

How to Eat Yaki Imo

You can eat it either hot or cold! Hot yaki imo are delicious, but cold ones are just as tasty. After the yaki imo cools down, open the foil, grab the yaki imo, divide it in half by hand, and eat from the middle. The inside should be a beautiful golden brown.

You can eat the purple skin of Japanese sweet potatoes (I always do), but if you don’t like the starchy texture, feel free to remove the single layer. Leave the end because it’s hard and tastes bitter, so you don’t want to eat that part.

Storage

After the yaki imo is completely cooled, remove its moisture by wrapping it tightly with cling wrap, placing it in a Ziplock bag (or an airtight container), and storing it in the fridge or freezer. It will last five days in the refrigerator and one month in the freezer.

Japanese Sweet Potato Varieties

There are many types of sweet potatoes in Japan, each with its own unique flavor and texture! If you have access to well-stocked grocery stores, especially local Asian or Japanese markets, I highly recommend exploring the different varieties to find your favorite.

  • Beni Haruka: The sweetest variety, creamy and rich in flavor.
  • Annou Imo: Gooey and extra sweet when roasted.
  • Silk Sweet: Soft with a smooth, slightly flaky texture.

    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.
