Gamja Jorim Recipe (Korean Soy-Braised Potatoes)

Gamja Jorim is a classic Korean potato side dish made by braising potatoes in a sweet and savory soy sauce glaze.

This version is especially chewy and flavorful because it is made without adding extra water. Instead, the potatoes are first mixed with sugar, oligosaccharide syrup, and plum extract. As the potatoes rest, they naturally release moisture, creating just enough liquid for braising.

The result is glossy, chewy, sweet, salty, and deeply satisfying Korean soy-braised potatoes that pair perfectly with steamed rice.

Ingredients

Main Ingredients

• 2 1/2 tbsp soy sauce
• A small amount of green onion

Ingredient Notes

Potatoes

Use firm potatoes that hold their shape well.

Cutting the potatoes into similar-sized cubes helps them cook evenly.

Oligosaccharide Syrup

Oligosaccharide syrup adds sweetness and gives the potatoes a glossy finish.

You can use corn syrup or Korean cooking syrup instead.

Sugar

Sugar helps draw moisture out of the potatoes before cooking.

This is what allows the potatoes to braise without adding water.

Korean Plum Extract

Korean plum extract adds a gentle sweetness and a slightly fruity depth.

If you do not have it, you can replace it with a little more syrup or sugar.

Soy Sauce

Soy sauce gives the dish its salty and savory flavor.

Start with 2 tablespoons, then add more near the end if needed.

Sesame Oil

Sesame oil is added at the end for aroma.

Do not add it too early because the fragrance is best when added after cooking.

How to Make Gamja Jorim

Step 1: Cut the Potatoes

Peel the potatoes and cut them into bite-sized cubes.

Try to keep the pieces similar in size so they cook evenly.

Step 2: Soak the Potatoes

Place the cut potatoes in cold water for about 10 minutes.

This removes excess starch and helps prevent the potatoes from becoming too sticky.

Rinse and drain well.

Step 3: Add Sweeteners First

Place the drained potatoes in a bowl.

Add:

• 1 tbsp sugar
• 1 tbsp oligosaccharide syrup
• 1 tbsp Korean plum extract

Mix well so the potatoes are evenly coated.

Let them sit for about 10 minutes.

During this time, the potatoes will naturally release moisture.

This liquid becomes the base for braising, so there is no need to add water.

Step 4: Start Cooking

Transfer the potatoes and the liquid they released into a pot.

Turn the heat to medium.

Cover with a lid and cook for about 5 minutes.

Step 5: Stir Gently

After 5 minutes, open the lid.

Gently stir the potatoes so they do not stick to the bottom.

Be careful not to break them.

Step 6: Add Soy Sauce

When the potatoes are about 80% cooked, add soy sauce.

Start with 2 tablespoons first.

Continue simmering until the potatoes absorb the sauce and the liquid reduces.

Taste near the end and add the remaining 1/2 tablespoon soy sauce if needed.

Step 7: Reduce the Sauce

Continue cooking while gently shaking the pot from time to time.

Avoid stirring too aggressively because the potatoes can break apart.

Cook until the sauce becomes thick and glossy.

Step 8: Add Green Onion

Add chopped green onion near the end.

Simmer briefly until the green onion softens slightly and blends into the sauce.

Step 9: Finish with Sesame Oil and Sesame Seeds

Turn off the heat.

Add a little sesame oil and sprinkle sesame seeds over the potatoes.

Mix gently once more.

Step 10: Serve

Transfer the Gamja Jorim to a serving dish.

Serve warm, at room temperature, or chilled.

Pro Tips

Do Not Add Water

The key point of this recipe is to let the potatoes release their own moisture.

Sugar, syrup, and plum extract draw out natural liquid from the potatoes, creating a thicker and more flavorful glaze.

Soak the Potatoes First

Soaking removes excess starch.

This helps the potatoes keep their shape and prevents the sauce from becoming too cloudy.

Add Soy Sauce Later

If soy sauce is added too early, the potatoes may become too salty before they are fully cooked.

Add it when the potatoes are about 80% cooked.

Shake the Pot Instead of Stirring Too Much

Potatoes can break apart easily.

Instead of stirring hard, gently shake the pot while reducing the sauce.

Adjust the Soy Sauce to Taste

The size and starchiness of potatoes can vary.

Start with less soy sauce and add more near the end if needed.

Store leftover Gamja Jorim in an airtight container in the refrigerator.
