Gamja Jorim Recipe: Korean Spicy Braised Potatoes

Gamja jorim (감자조림, "braised potatoes") is a Korean banchan — a small side dish served alongside rice as part of a full Korean meal. Small potatoes are fried until crispy, then braised in a sweet-spicy-savory sauce that reduces to a sticky glaze. The exterior is slightly chewy and caramelized; the interior is soft. The sauce is sweet from corn syrup, spicy from gochujang, and savory from soy.

It takes 20 minutes, requires almost nothing, and is one of the Korean dishes that non-Korean people most consistently make at home after trying it once.

Ingredients (serves 4 as banchan)

• 500g (about 1 lb) small baby potatoes (or regular potatoes cut into 2cm cubes)
• 2 tablespoons neutral oil
• 3 cloves garlic, minced

The sauce:

• 2 tablespoons soy sauce
• 1 tablespoon gochujang
• 1 tablespoon gochugaru (Korean chili flakes) — reduce for less heat

• ½ tablespoon sesame oil
• ½ cup water

To finish:

• 1 teaspoon toasted sesame seeds

Instructions

Step 1: Par-cook the Potatoes

If using baby potatoes: rinse and leave whole. If using regular potatoes: peel and cut into 2cm cubes.

Place in a pot, cover with cold salted water, bring to a boil, cook 8-10 minutes until just barely tender when pierced — they should not be fully cooked at this stage. Drain.

Why par-cook first: Starting with fully raw potatoes in the sauce produces uneven cooking and requires too much liquid, diluting the glaze. Par-cooking ensures the potato is cooked through by the time the sauce reduces to the right consistency.

Step 2: Crisp the Potatoes

Heat oil in a wide pan over medium-high heat. Add the par-cooked potatoes in a single layer. Cook, turning occasionally, 5-7 minutes until the exterior is golden and crispy. The slight crust on the outside will hold the glaze better.

Step 3: Make the Sauce

While potatoes crisp, mix soy sauce, gochujang, gochugaru, sugar, corn syrup, and water in a bowl. Stir until combined.

Add minced garlic to the pan with the potatoes and cook 30 seconds. Pour the sauce over the potatoes.

Step 4: Braise and Glaze

Toss to coat. Bring to a simmer. Cook over medium heat, stirring occasionally, 5-8 minutes until the sauce reduces to a thick, sticky glaze that coats every potato. The sauce should be barely liquid — mostly coating the potatoes in a dark, shiny layer.

Drizzle sesame oil over the top. Remove from heat.

Serving

Transfer to a serving plate. Scatter sesame seeds and scallions. Serve as part of a Korean meal alongside rice, kimchi, and other banchan.

Temperature: Gamja jorim is best at room temperature or slightly warm. Unlike some banchan that must be served hot, this dish is traditionally served at room temperature as part of a spread. It doesn't need to be piping hot.

Storage: Keeps 3-4 days refrigerated. The flavors deepen overnight. Eat cold from the refrigerator or briefly microwave. Don't try to re-crisp; the texture changes with storage and that's fine — it becomes chewier, which many people prefer.

Heat Level

The recipe as written produces a moderately spicy dish. Adjustments:

• Milder: Omit gochugaru entirely; use only gochujang. The sauce stays sweet-savory without significant heat
• Spicier: Double the gochugaru; add ½ teaspoon gochugaru directly to the oil before frying the potatoes
• No heat: Replace gochujang with doenjang (1 teaspoon) and omit gochugaru; produces a savory-sweet version without spice

Why Corn Syrup

Korean cooking uses corn syrup or rice syrup (mulyeot) to create the glossy finish in jorim (braised) dishes. Sugar can produce the same result but caramelizes more quickly and unevenly. The syrup stays liquid longer, giving more control over the glaze consistency. Honey works as a substitute but adds its own flavor.
