Cooking Steps

To begin the cooking process, preheat your oven to 400°F (200°C).
Grab your Korean sweet potatoes and give them a good rinse under cool water. Pat them dry with a clean towel.
Now, you'll want to pierce the potatoes a few times with a fork. This helps steam escape during baking, preventing any explosions in your oven!
Next, place the potatoes directly on the oven rack or on a baking sheet lined with foil or parchment paper. Bake for 40-50 minutes, until they're tender when poked with a fork. The size of your potatoes will determine the exact baking time.
Once they're done, carefully remove the potatoes from the oven. Let them cool for 5 minutes before handling.
Slice them open and fluff the insides with a fork. Top with a pat of butter, a sprinkle of cinnamon, or a drizzle of honey for an extra sweet treat.
Enjoy your perfectly baked Korean sweet potatoes!
Step 1. Wash and Scrub the Potatoes

Before you begin baking, thoroughly wash and scrub the potatoes under running water. This crucial first step ensures your Korean sweet potatoes are clean and ready for baking. Use a vegetable brush to gently scrub the skins, removing any dirt or debris. Pay close attention to the nooks and crannies, making sure to clean the entire surface of each potato.
Once they're sparkling clean, give the potatoes a final rinse. This helps remove any lingering particles and gets them prepped for the oven. Don't skip this step – you want the skins to be as clean as possible before baking.
Now that your potatoes are washed and scrubbed, you're one step closer to enjoying their sweet, delicious flesh. The next phase is piercing the skins to allow steam to escape during cooking.
With a little prep work, you'll have perfectly baked Korean sweet potatoes ready to enjoy.
Step 2. Preheat Oven to 400°F

Preheat your oven to 400°F. This crucial first step ensures your oven is the perfect temperature for baking those delicious Korean sweet potatoes. Setting the oven to this high heat will help create a crispy skin on the outside while keeping the insides soft and sweet.
Once your oven is preheated, you'll be one step closer to enjoying the mouthwatering results. The high temperature helps caramelize the natural sugars in the sweet potatoes, bringing out their incredible flavor.
Be sure to use an oven thermometer to double-check that your oven has reached the correct temperature – this will guarantee your potatoes bake evenly.
With the oven ready, you can move on to the next steps in the baking process. Get excited, because your kitchen is about to smell amazing as those sweet potatoes roast to perfection!
Step 3. Pierce the Potatoes

After preheating the oven, pierce the sweet potatoes several times with a fork. This helps release steam as they bake, preventing the potatoes from bursting.
Be sure to poke a few holes all around each potato – don't be shy! The more vents you create, the better. This simple step ensures your Korean sweet potatoes will bake up perfectly every time.
Once you've given each potato a good poking, place them directly on the oven rack. You can also use a baking sheet lined with foil or parchment paper if you prefer.
Just be sure to leave a little room between the potatoes so they can cook evenly. As they bake, the outsides will become crispy and golden, while the insides will become soft and sweet.
The fork holes you made earlier will allow all that delicious flavor to really shine through. In about 45-55 minutes, your Korean sweet potatoes will be tender and ready to enjoy!
Step 4. Bake Potatoes for 40-50 Minutes

With the potatoes pierced and ready, simply slide the oven rack with the sweet potatoes in and let them bake for 40-50 minutes.
You'll want to keep a close eye on them, as the baking time may vary depending on the size of your sweet potatoes. They're ready when a fork can easily pierce through the soft, caramelized flesh.
While they're baking, your kitchen will fill with the most amazing aroma – a blend of toasted sweetness that'll have your mouth watering.
Don't be surprised if your family starts gathering around the oven, eagerly awaiting those delicious Korean sweet potatoes.
Once they're done, you can easily check for doneness by giving them a gentle squeeze. If they feel soft and give way, they're ready to enjoy.
Serve the baked sweet potatoes hot, straight from the oven. Their sweet, creamy insides pair perfectly with a sprinkle of cinnamon or a drizzle of honey.
Get ready for the ultimate cozy, comforting treat!
Step 5. Remove Foil and Enjoy

Once the baking time is up, carefully remove the sweet potatoes from the oven. The delicious aroma will fill the air, tempting you to dive right in.
But hold on – you'll want to let them cool for a few minutes first. This will allow the insides to finish cooking and become perfectly tender.
Once they've had a chance to rest, it's time to enjoy the fruits of your labor! Gently remove the foil, being careful not to let any steam escape.
Peek inside and marvel at the vibrant, golden color of the sweet potatoes.
Now, the best part – grab a fork and dig in! The soft, creamy texture will melt in your mouth, while the natural sweetness of the Korean sweet potatoes shines through.
