The Magic of Waterless, Oil-Free Braised Potatoes
Korean braised potatoes, known as Gamja-jorim, are a staple side dish (banchan) beloved by many. However, achieving that restaurant-quality texture—where the potatoes are perfectly chewy on the outside, soft on the inside, and beautifully glazed without turning into mush—can be remarkably tricky at home.
Today, I am sharing a game-changing recipe that breaks the traditional rules. We are not going to use a single drop of water or cooking oil. Instead, we will rely on the natural moisture of the potatoes and the science of osmosis. This innovative method guarantees that your potatoes will hold their shape perfectly while developing a glossy, irresistible texture.

1. What You Need
Main Ingredients

Seasoning & Glaze

2. Step-by-Step Instructions
Step 1: Prep the Potatoes
Peel the potatoes and cut them into bite-sized cubes (about 1 inch). Soak the cubes in cold water for 10 minutes to remove excess surface starch. This prevents them from becoming overly sticky or burning later on. Drain well.
Step 2: The Osmosis Trick (No Water Needed!)
Place the drained potatoes in a pot or pan. Add the sugar, oligosaccharide, and plum extract (do NOT add the soy sauce yet). Toss everything together, cover with a lid, and let it sit for 10 to 15 minutes. The sugars will draw out the natural moisture from the potatoes, creating a shallow pool of liquid at the bottom of the pot.
Step 3: Steam-Cook in Natural Juices
Turn the stove on to medium heat. Keep the lid on and let the potatoes gently boil in their own extracted juices for about 5 minutes. They will essentially steam themselves, becoming tender without the need for added water or cooking oil.
Step 4: Add the Savory Flavor
Open the lid and check the potatoes with a fork or chopstick. Once they are about 80% cooked, pour in the soy sauce. Adding the soy sauce later ensures the potatoes do not become tough and allows the flavor to penetrate perfectly.
Step 5: Braise and Glaze
Leave the lid off and continue to simmer over medium-low heat. To keep the potatoes from breaking, avoid stirring too vigorously. Instead, gently shake the pan or carefully fold with a silicone spatula. Simmer until the liquid has almost completely evaporated and the potatoes are coated in a thick, sticky glaze.
Step 6: Final Touches
Toss in the chopped green onions and cook for another minute. Turn off the heat, drizzle with sesame oil, and sprinkle with toasted sesame seeds.

3. Pro-Tips for Success
- Adjusting the Saltiness: Since the size of potatoes can vary, start with 2 tablespoons of soy sauce. Taste near the end of the cooking process and add the remaining half tablespoon only if needed.
- Storage: Because this recipe uses no added water and no oil, it stores exceptionally well in the fridge. The glaze won't turn cloudy or greasy. Simply microwave for 30 seconds before eating to restore that fresh, chewy texture!
Serve this perfect sweet and savory Gamja-jorim alongside a bowl of freshly steamed rice, and you will understand why it's considered the ultimate comfort banchan!
