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.

How To Make Yaki Imo: STEP BY STEP
Here’s a quick visual guide! Check the recipe card below for the video and full details!

Step 1
Wash off Japanese sweet potatoes, dry them, and wrap them in foil.

Step 2
Place them on a baking sheet and roast at 180°C (356°F) until tender.

There you go! When you open it, it looks like this, and it’s super hot!
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.

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.
Hi Eurico, I didn’t know that! I would love to try Portuguese roasted sweet potatoes! Thanks for sharing:)
