Roasted goguma can be found in street food stalls across Korea, often sold hot and wrapped in foil. Additionally, they can be boiled, steamed, or used in soups and stews.
In addition to savory preparations, goguma is also used in dessert recipes. It can be pureed and sweetened to make traditional Korean sweets, such as “goguma taffy,” or incorporated into pastries and cakes. This versatility makes Korean sweet potatoes a beloved ingredient in both home-cooked meals and professional culinary settings.

Many larger supermarkets with dedicated produce sections may carry them, especially in areas with significant Korean or Asian populations.

When buying, look for firm sweet potatoes with smooth skin and avoid those with blemishes or soft spots. It’s best to check in the fall and winter months when they are in season and at their freshest.
Can I grow Korean sweet potatoes at home?
Growing Korean sweet potatoes at home is possible and can be quite rewarding! They can be cultivated in a garden or in containers, provided they have enough space and warmth. Sweet potatoes thrive in well-drained soil and need full sunlight to develop properly. For best results, plant them in late spring after the last frost, as they require warm temperatures to grow.
To begin, you can purchase goguma slips, which are young plants grown from sweet potatoes. Plant them about 12 inches apart and water them regularly. With careful attention, you can harvest your own delicious goguma by the end of summer or early fall, depending on your climate.
What is the best way to store Korean sweet potatoes?
To ensure the longevity and quality of Korean sweet potatoes, it is important to store them properly. They should be kept in a cool, dry place, preferably in a breathable container or in a paper bag. Avoid plastic bags, as they can trap moisture and lead to spoilage. An area in your kitchen or pantry that remains consistent in temperature works well.
If you have already cooked the sweet potatoes, store any leftovers in an airtight container in the refrigerator. Cooked goguma can typically last for about 3 to 5 days when refrigerated, retaining their delightful flavor and texture for your next meal.
Can I use Korean sweet potatoes in recipes that call for regular sweet potatoes?
Absolutely! Korean sweet potatoes can be seamlessly incorporated into recipes that typically use regular sweet potatoes. They can be roasted, mashed, or used in soups and stews without compromising on taste or texture. However, keep in mind that the flavor profile may differ slightly, as goguma tends to be sweeter and denser than many other varieties of sweet potatoes.
When substituting Korean sweet potatoes in a recipe, monitor cooking times closely since they may vary. Experimenting with goguma can add a unique twist to classic sweet potato dishes, and you might discover new flavors you love along the way!
