Japanese Sweet Potatoes

Japanese sweet potatoes, also known as satsumaimo, are easily distinguished by their burgundy skin and yellowish-white flesh.

They are typically firmer and starchier than orange sweet potatoes, which makes them an excellent choice for roasting, grilling, or using in soups and stews, as they hold their shape well during cooking.

Japanese sweet potatoes are versatile and commonly used in sweet and savory dishes in Japanese cooking. Some popular dishes are sweet potato tempura, yaki imo (roasted sweet potato), daigaku imo, and baked treats.

How to make it is super easy! Let me show you how.

1. Cut vegetables
2. Cook onions
3. Cook sweet potatoes
4. Simmer for 10 minutes over low heat
5. Blend until smooth using a blender
6. Warm the soup up

Step 1

Slice the onion thinly.

Peel the sweet potato and cut into small pieces. Place the sweet potatoes in a medium-sized bowl and add enough water to cover them. Soak for 5 minutes, then drain the water.

Step 2

Heat the olive oil in a medium saucepan over medium heat. Add the sliced onion and cook until tender.

Step 3

Add the sweet potatoes and cook for a few minutes.

Step 4

Pour water into the saucepan and add the bouillon. Bring to a boil, cover, and simmer for 10 minutes over low heat or until the sweet potatoes are tender.

Step 5

Transfer the soup to a blender container and add soy milk.

Blend until smooth and creamy.

Step 6

Transfer the soup back to the saucepan and warm it up over low heat. Be sure to remove the pan from the heat before it boils. Season the soup with salt to taste.

Serve

Enjoy your warm and comforting bowl of sweet potato soup! Feel free to add crispy croutons for extra crunch!

For added flavor, you can sprinkle garlic powder and black pepper on top of the sweet potato soup according to your personal preference.

Transfer the soup to an airtight container and store it in the refrigerator. The soup can be stored for up to 3 to 4 days.

• The Japanese sweet potato skins are edible and contain valuable nutrients, just like other varieties of sweet potatoes. Typically, I cook them with their skins on, but I peel off the skins to achieve a beautiful, creamy white color for this soup recipe.
• Soaking sweet potatoes can not only help to remove the bitterness but also help to prevent the color from changing or darkening.
