Gamja Jorim (Korean Braised Potatoes in 20 minutes)
If you’ve ever been to Korean BBQ and found yourself eating the little glazed potatoes faster than anything else on the table, this is THAT dish. Gamja jorim or Korean braised potatoes, is one of those banchan that looks simple but somehow disappears faster than the main course.
Tender potato chunks pan-fried until golden, then simmered in a sweet, savory soy glaze until sticky and glossy. The whole thing takes 20 minutes and uses pantry staples you already have. I used to beg the server for refills but now I just make a big batch at home!

What is gamja jorim?
Gamja jorim (감자조림) is a classic Korean banchan and one of the small side dishes served alongside rice in Korean meals. “Gamja” means potato, “jorim” refers to the braising technique of simmering food in a seasoned sauce until it reduces and coats everything in a glossy glaze.
It’s a staple of Korean home cooking, the kind of dish that’s been on family tables for generations because it’s cheap, easy, and genuinely delicious! The potatoes get pan-fried first for color and texture, then braised in a soy, water, and sugar sauce that reduces down into a sticky, caramel-edged glaze.
This dish requires no specialty ingredients, just your kitchen staples. It’s mild enough to pair with almost anything and satisfying enough to eat straight over rice!
Why this recipe works
Pan-frying before braising is the step that matters most.
- A lot of gamja jorim recipes skip straight to simmering the raw potatoes in sauce. That works, but you miss the slightly crisped exterior that holds up to braising without falling apart. Two to three minutes in hot oil first gives the potatoes a thin, golden skin that keeps them intact and adds texture that makes each bite more interesting.
Sesame oil goes in last, not first!
- This is a rule worth knowing for a lot of Asian cooking: toasted sesame oil loses its aroma and nutty flavor when exposed to high heat. Adding it after the heat is off means you actually taste it in the finished dish rather than cooking it away.
The sauce reduces, not the potatoes
- The 10-minute simmer reduces the sauce down into a thick, sticky glaze that coats every piece. Don’t rush it by turning up the heat, or the sauce burns before it coats properly.
What type of potato works best
Almost any potato works here, which is what makes this recipe practical! It’s designed for whatever you have. That said, there are real differences worth knowing:
Waxy potatoes (Yukon Gold, red potatoes, baby potatoes) hold their shape best during braising. They have less starch, which means they don’t fall apart in the sauce and stay firm even after 10 minutes of simmering. Best choice if you want clean, intact pieces.
Russet/starchy potatoes will work but are more likely to crumble during the braise. They absorb the sauce quickly and can fall apart at the edges. Still delicious, just more rustic in appearance. Cut them slightly larger to compensate.
Baby potatoes halved are the easiest. No peeling needed, it will be uniform size and they hold up well to braising. Worth keeping a bag in the fridge specifically for this recipe!
Tips for the best gamja jorim
Cut potatoes evenly.
- Uneven pieces mean some are overcooked by the time the larger ones are done. Aim for roughly 1.5-2 inch chunks and they will be consistent enough to cook at the same rate, small enough to fully absorb the glaze.
Don’t overcrowd the pan.
- If the potatoes are packed in too tightly during the pan-fry step, they steam instead of brown! Spread them out in a single layer and give them space.
Taste and adjust at the end.
- Soy sauce varies significantly by brand in saltiness so taste the glaze before adding sesame oil and adjust with a pinch of sugar if too sharp, or a splash more water if too thick.
Double the batch.
- This takes the same amount of effort whether you make one serving or four, and it tastes even better the next day. The potatoes absorb more glaze overnight and the flavors deepen significantly in the fridge.
What to serve with gamja jorim
Gamja jorim is one of the most versatile banchan you can make , it pairs naturally with almost anything Korean:
Korean BBQ spread:
- alongside grilled samgyeopsal or galbi with my Ssamjang, Bossam, and Quick Korean Pickled Radish for a full banchan spread that actually feels like a Korean restaurant at home.
Simple rice bowl
- a spoonful of gamja jorim over steamed white rice with a fried egg is a complete, satisfying meal on its own. The glaze doubles as a sauce for the rice.
Korean fish cake stir fry
- another classic banchan that pairs naturally with these potatoes as part of a side dish spread. Check out my Korean Fish Cake Stir Fry recipe.
Storage and Reheating
Gamja jorim is one of the rare Korean dishes that stores exceptionally well. Unlike most stir-fries that lose texture overnight, these actually improve after a day in the fridge as the potatoes absorb more of the glaze.
Refrigerator:
- Up to 4 days in an airtight container. The glaze will thicken as it cools, that’s normal and not a sign it’s gone bad.
Reheating:
- Reheat in a pan over medium-low heat with a small splash of water to loosen the glaze. Microwave works too but can make the edges slightly rubbery. A pan reheat takes 2 minutes and is noticeably better.
Freezer:
- Not recommended! Potatoes don’t freeze well and become grainy and watery after thawing.
Frequently Asked Questions
What does gamja jorim taste like?
- Sweet, savory, and slightly sticky. The soy gives it a deep umami base, the sugar rounds it out, and the sesame oil adds a nutty finish.
What is banchan?
Banchan are the small side dishes served alongside rice in Korean cuisine. They are usually several at once, meant to complement the main dish and rice. Gamja jorim is a classic banchan found in Korean home kitchens and restaurants alike.
Can I make gamja jorim ahead of time?
Yes, it’s actually better the next day. Make a full batch, refrigerate overnight, and reheat with a splash of water. The glaze deepens and the potatoes absorb more flavor after sitting.
Why are my potatoes falling apart?
Usually one of three things: potatoes were cut too small, overcooked during the simmer, or a starchy variety (like russet) was used without adjusting the cook time. Use waxy potatoes where possible, cut into 1.5-2 inch chunks, and watch the simmer carefully.
Ingredients
- 1 lb Potato, cut into 1.5-2 inch chunks
- 3 tbsp Soy sauce
- 1 tbsp Sugar
- 1/2 cup Water
- 2 cloves Garlic, minced
- 1/4 medium Onion, sliced
- 2 tsp tToasted sesame oil (added at the end)
- 1 tsp Sesame seeds, for garnish
Step by step instructions
1. Prep the ingredients
Rinse the potatoes well and peel and trim any bruised spots. Cut into even 1.5-2 inch chunks, consistent size matters for even cooking. No need to peel if using thin-skinned varieties like baby potatoes or red potatoes. Dice your garlic and slice onions finely.
2. Pan-fry until golden
Heat neutral oil in a large pan over medium heat. Add the potatoes in a single layer and pan-fry for 2-3 minutes, turning occasionally, until lightly golden on the outside. Add garlic and onion, and stir fry for a minute.
3. Add the braising sauce
Add the soy sauce, water, sugar to the pan. Stir to combine and bring to a boil.
4. Simmer uncovered
Reduce to medium heat and simmer for about 10 minutes, stirring occasionally, until the sauce has reduced into a thick, sticky glaze that coats the potatoes. If the sauce reduces too fast before the potatoes are tender, add a small splash of water and continue.
5. Finish with sesame oil
Turn off the heat. Add the toasted sesame oil and toss well to coat. Taste and adjust with sugar, soy sauce and/or water.
6. Serve
Transfer to a bowl, sprinkle with sesame seeds, and serve immediately alongside rice or as part of a Korean BBQ spread.
