All About Korean Sweet Potatoes (고구마)
Korean sweet potatoes, called goguma (고구마) are a healthy, delicious snack that's popular all throughout Korea. They're sweet, satisfying, and full of healthy carbohydrates that will keep you full for hours.
They're so popular in Korea, they're sold from street vendors and even made into cakes, cookies, chips, and bread!
Varieties of Korean sweet potatoes:
Bam goguma 밤고구마 (Chestnut sweet potatoes): These have a chestnut like flavor and turn a golden, yellow color when roasted. The flesh is slighter more dense and dry. The skin is edible with a reddish, purple hue that gets crispy when baked.
Mul goguma 물고구마 (Water sweet potatoes): Water sweet potatoes have a higher water content compared to chestnut sweet potatoes, hence their name. They also have a reddish, purple skin with a golden yellow flesh, though they come smaller in size.

Korean sweet potatoes vs American sweet potatoes
American sweet potatoes have a bright orange flesh and high water content making them great for casseroles and mashed sweet potatoes.
The Korean variety on the other hand, usually have a yellow or pale white flesh with a denser, drier texture depending on the variety. I find the Korean variety to be sweeter, though they're both great options for baking and roasting.

How to Bake Korean Sweet Potatoes
- Wash and dry the sweet potatoes then take a fork and poke about 5 to 6 holes per potato. This is to help the steam vent during the bake.
- Place it on a baking rack lined with parchment paper and bake at 400 degrees F for 45 minutes to 1 hour, depending on the width of the sweet potatoes.
- They're ready when soft and fluffy. Use a fork or toothpick to pierce the sweet potatoes to check that it's fork tender. The skin should start to wrinkle and easily separate from the flesh when removed from the oven.
