There’s something magical about Korean sweet potatoes—soft, nutty, almost chestnut-like in flavor, with a caramelized golden hue that feels like a hug from the oven. We discovered this gem of a recipe one chilly evening, craving comfort but not wanting the usual starchy suspects. From the first bite, we were hooked.

And since then, this dish has become a regular on our family table—whether it’s for a festive dinner or just a cozy night in socks and sweatshirts.

What makes this recipe so special? It’s the simplicity, the versatility, and most of all—the way it makes you feel like you’re indulging in something decadent, even though it’s just nature doing its thing with a little help from heat. There’s no need to smother it in sugar or drown it in oil. The flavor sings solo. But if you’re in the mood to jazz it up—we’ve got plenty of ideas.

The first time we made this, the smell drew everyone to the kitchen long before the timer rang. It was warm. Nutty. Inviting. We’ve tried every possible method—oven roasting, air frying, steaming, even microwaving when desperate—and each version has its charm. In this recipe, we’ll guide you through every method we’ve tested (and loved).

The Steps of Preparation

Below are the cooking methods we’ve personally tested—whether you’re into oven roasting, microwaving in a pinch, or want that perfectly crisp skin in the air fryer, we’ve got you covered. Choose the one that suits your kitchen setup or mood best.

1. Wash the sweet potatoes thoroughly, scrubbing off any dirt.
2. Dry them completely with a kitchen towel.
3. For oven baking: Preheat oven to 200°C (400°F), prick potatoes with a fork, place on a parchment-lined baking sheet.
4. Bake for 45–60 minutes, flipping halfway through, until they caramelize and ooze a little at the edges.
5. For air fryer: Preheat to 190°C (375°F), place sweet potatoes directly in the basket.
6. Air fry for 30–40 minutes, shaking the basket halfway through.
7. For microwave: Wrap each sweet potato in a damp paper towel, place on a microwave-safe plate.
8. Microwave on high for 6–8 minutes, turning halfway. Check tenderness with a fork.
9. For Instant Pot: Add 1 cup of water, place sweet potatoes on a trivet, cook on high pressure for 15–20 minutes.
10. Release pressure naturally for 10 minutes before opening lid.
11. Let sweet potatoes rest for 5–10 minutes after cooking for flavors to settle.
12. Slice open gently, sprinkle with salt, sesame, or your chosen toppings.
13. Serve warm, with love.
