The Best Korean Potato Salad (Gamja Salad)

One of the great things about living in the UK is getting to eat the wonderfully delish Jersey Royal potatoes!

One of the great things about living in the UK is getting to eat the wonderfully delish Jersey Royal potatoes! My favorite spud in the USA has to be the Yukon golds, for their gorgeous gilt hues and naturally buttery taste. Jersey Royals are only available from April to June every year because they are hand planted in January on the isle of Jersey, in sloping fields (called côtil) overlooking the sea. The seed potatoes are fertilized with seaweed, called vraic. The local farmers protect the potatoes during winter frosts by covering the fields with fleece blankets. The result is a truly flavorsome potato, creamy in texture with gorgeous earthy nutty notes.

I thought it was the perfect tater to make a classic Korean potato salad! Known as Gamja Salad, is very similar to western potato salad, but usually incorporates either cucumber or apples for added crunch and sweetness. You’ll often see it as a side dish, or banchan, in Korean restaurants coming out alongside kimchi and other namul / vegetable dishes. I always thought it was a bit random, but it has always been a popular banchan for as long as I can remember.

The Best Korean Potato Salad (Gamja Salad 감자샐러드)

Usually, the potato salad is spooned into a dish using an ice cream scoop and made with either mashed or chunky cooked potatoes. Its roots probably go back to southern cooking, and this dish coming to Korea via American GIs.

I have jazzed my version up a bit:

- I’m using jersey royals and leaving the skin on. I love the texture and the skin provides a lot of nutrients, including vitamin B, C, iron, potassium and calcium.

- Deseed the cucumber. The extra water from the seeds can make your salad too loose. I also like to cut it a bit smaller than the dice sized pieces normally found in Korean potato salad. I like the crunch, but I don’t like large pieces interfering too much with the creaminess of the salad.

- Soak the shallot in water to remove the harsh onion bite.

- Keep the carrots raw, but finely dice them. The sweetness comes through more with raw carrots and I like the nuanced bit of crunch the smaller cut provides.

- Use a good mayo. I like to use Kewpie Japanese mayo as it has more tang and sweetness. Hellmann’s is a good choice too. You can always add some sugar or vinegar later. If you are watching your cholesterol, feel free to use a canola oil based mayo that is cholesterol free.

- Season the water when boiling the potatoes. I like to add an organic bouillon cube (either chicken or vegetable). If you season your boiling water nicely, the better your potatoes will taste.

- Feel free to add apples or raisins, which is also very common. I have opted for corn in my recipe below as summer corn is in season right now and so tasty!

- Ham is also a popular addition.

If you want to make this more Mediterranean style, feel free to use extra virgin olive oil instead of mayo. You won’t need as much, it is healthier too! You can also add a dollop of Dijon mustard to boost the flavor.

Ingredients

  • 1kg (2.2lbs) Jersey new potatoes, or russet potatoes
  • 3 large eggs
  • 2 ears of corn
  • 2 medium carrots (about 75g / 2.6 oz each carrot)
  • ½ English cucumber or 2 small Kirby or Persian cucumbers
  • 1 echelon shallot, or 2 small round shallots, peeled, halved and placed in a bowl of cold water.
  • 160g (1 cup) Kewpie mayo or your favorite mayo
  • Sea salt
  • Freshly ground black pepper

Method

Wash your potatoes well, using a sponge or soft brush to scrub the skins free of any dirt. Remove any eyes and black blemishes, and place the cleaned potatoes in a large pot of cold water. Place the pot on a stove over high heat. Add a generous amount of salt and a bouillon cube of your choice (either chicken or vegetable, optional) to season the water. Bring to a boil and then lower to a high simmer and cook until the potatoes are soft and able to be pierced easily with a fork. Drain in a colander set over a sink and allow to cool slightly.

Clean the pot out and fill with water. Place on the stove over high heat and carefully place in the eggs, and two ears of corn. Bring to a boil and lower to a simmer. Using tongs, remove the corn once cooked, about 3-4 mins, and set aside to cool. Then using a slotted spoon remove the eggs once hard boiled, about 9-10 mins. Discard the hot water into the sink and place the drained slightly cooled potatoes back into the pot.

Run the eggs under cold water and peel the shells off, cut the eggs into dice sized pieces and place into a large bowl. Using a sharp knife, cut the kernels off the cobs of corn, and place into the same large bowl as the eggs.

Peel the carrots and then cut into thin strips or julienne using a sharp knife or a julienne peeler. Then cut the thin strips into small diced sized pieces (brunoise). Place into the large bowl with the eggs. Remove the shallot halves from the bowl of water and finely chop. Place into the same large bowl.

Cut the cucumber in half lengthwise and using a spoon, scrape out the seeds and discard. Cut the cucumber into ¼ inch or ½ cm sized pieces. Place into the same large bowl. Add the mayo to the bowl and mix with the vegetables.

Using a potato masher, crush the potatoes well, breaking them apart fully. Tip the potatoes into the large bowl with the vegetables and mayo. Mix well and season with salt and pepper, to taste.

If you want your salad a bit sweeter add 1 tsp of white sugar, and to add some more tang, add 1 tsp of Korean apple vinegar or rice vinegar. Place in an airtight container and in the fridge to store, it will stay fresh for 2-3 days after making.

Serve this salad with Korean barbecue as a side dish or as a lunch time snack. In Korea you will often see Gamja salad sandwiches also. Just place a scoop in a soft white roll. I prefer a bit of crunch, so I’ll spread mine over toasted sour dough and eat it like an open-faced sandwich. You can also use this salad to make croquettes. Just form into patties, dreg in beaten eggs, coat in panko breadcrumbs and fry. Serve hot with mustard, tonkatsu and/or ketchup on the side to dip!

@judyjoochef Instagram profile imageMore from my South America adventure ✨ After Peru, we headed to Argentina and Brazil to finally see Iguazu Falls—a place I’ve been quietly (okay, obsessively) dreaming about for years. One of the New Seven Wonders of Nature, and the world’s largest waterfall system, Iguazu is made up of more than 275 cascades plunging up to 82 meters on the Argentina–Brazil border. And in rainy season? The water volume can swell to 7.5 times its usual flow—up to 3.4 million gallons every second. Translation: every other waterfall now feels like a kitchen tap. Seeing Iguazu in person was jaw-dropping, humbling, and wildly emotional. Truly one of the most extraordinary natural sights I’ve ever experienced—and absolutely worthy of a prime spot on everyone’s bucket list. Do both sides if you can: Argentina immerses you inside the falls, while Brazil gives you sweeping panoramas—and private boat and helicopter tours you can’t do on the Argentine side. We stayed at the exceptional Awasi Iguazú @awasiexperience (a longtime favorite since Patagonia, and yes—another Relais & Châteaux gem). Awasi’s bespoke approach is next level: your own private guide and vehicle, daily excursions tailored exactly to what you want, plus private after-hours access to the park and train to Devil’s Throat—meaning we experienced the falls without the crowds. Absolute magic. Evenings were spent dining outdoors on an open terrace, listening to the jungle’s nightly symphony—birds, frogs, cicadas all chiming in. The food was fantastic, the atmosphere unforgettable, and I even spotted my very first toucan in the wild. Pure joy. Huge thank you to Cazenove+Lloyd @cazenove_and_loyd for seamlessly handling every detail of the journey—and special gratitude to @beckyfenn87 for saving the day when our flights were canceled and rerouted with calm, grace, and superhero efficiency. The music for this reel is from The Mission, filmed on location at the falls and starring Robert De Niro and Jeremy Irons. The score—by the legendary Ennio Morricone—has long been one of my favorites, and hearing it while standing before those falls felt perfectly, powerfully full-circle. #judyjoo #travel #iguazu #bucketlisttravel1 week ago via Instagram
@judyjoochef Instagram profile imageMore from my Peru journey—and this chapter was pure magic. My trip was beautifully planned by Cazenove+Lloyd @cazenove_and_loyd, and I soaked up every moment exploring the Sacred Valley, set high at 9,200 feet and overflowing with jaw-dropping views, ancient history, and quiet moments of wonder. We wandered through the remarkable Maras Salt Mines, carved directly into the valley—where mineral-rich mountain stones naturally yield salt prized for its purity, minerals, and superior taste. Nearby, ancient Incan ruins reveal that ingenious tiered agricultural engineering, both a necessity and a marvel to behold. We stayed at the utterly divine Sol y Luna Hotel @solylunahotel—tucked into the valley and surrounded by lush gardens where hummingbirds and butterflies seem to appear on cue. The food was a true highlight (Relais & Châteaux always gets it right), with soulful local specialties (Cuy!) alongside a few comforting standbys—yes, a soy milk latte always finds me! Visiting the Sol y Luna Foundation @solylunafoundation, which includes a school and “orphanage” (the kids are not technically orphans, but they have very challenging home situations), was incredibly moving. I fell in love with some of the children—especially those who simply wanted to be held. I also had the chance to indulge in a traditional Pachamanca lunch at @Las_Qolqas (a charming eco glamping haven)—one of the Andes’ most meaningful culinary rituals. Pachamanca, which means “earth pot” in Quechua, is both a dish and an ancient cooking method: marinated meats like lamb, pork, and chicken, along with potatoes, corn, and beans, are layered with aromatic herbs such as huacatay, wrapped in leaves, and slow-cooked underground over hot stones. The result is unforgettable—smoky, tender, and infused with deep, earthy flavors that truly reflect the land. Add long hikes, an adventurous off-road bike ride alongside a roaring river through the mud, and days filled with delicious meals, muddy shoes, and endless smiles, and I had a Sacred Valley experience I’ll never forget. #travelgram #peru #judyjoo #cheflife @beckyfenn871 week ago via Instagram
@judyjoochef Instagram profile imageMy journey through Peru continued from the Amazon rainforest to Machu Picchu and Cusco—a chapter I’ve been dreaming about for a very long time. There is something deeply satisfying about finally ticking off a true bucket-list moment, and Machu Picchu delivers on *every* promise. It is absolutely worth the hype—and the effort it takes to get there. The journey alone feels epic: a two-hour panoramic train ride, followed by a slightly harrowing 30-minute bus climb up the mountain, all switchbacks and hairpin turns. And then, of course, you hike. You climb. You work for it. And only then are you rewarded with a view of truly epic proportions. Standing there, it’s impossible not to marvel at the Incas—their advanced engineering, the precision, the mystery of how and why they built this breathtaking city in the clouds. With no written language, we’ll never fully know their story, but the beauty and ingenuity speak volumes. In Cusco, we stayed at the exquisite Belmond Palacio Nazarenas @belmondpalacionazarenas @belmond —a converted convent filled with atmospheric corridors and tranquil courtyards. Our room blended old-world charm with thoughtful modern comforts—oxygen pumped in at night (Cusco sits at 11,000 feet), hot water bottles tucked into the bed, and food that was genuinely swoon-worthy. Breakfast was a daily joy: freshly baked breads and croissants that could rival Paris, paired with locally brewed Peruvian coffee—instant happiness. Dinner was equally memorable, with dishes by Pía León @pialeonkjolle, weaving local ingredients into refined, soul-warming plates. The spa was pure bliss and exactly what my feet and legs needed after long days of hiking. Cusco ended up being one of my favorite cities of the entire journey—and this adventure is far from over. More to come. Thank you to @cazenove_and_loyd @beckyfenn87 for arranging the most luxe trip! #judyjoo #traveling #peru #machupicchu1 week ago via Instagram
@judyjoochef Instagram profile imageReturning to the H Club at Tottenham Hotspur Stadium with @chefandrewhales for a fourth season feels both grounding and exhilarating—like revisiting a favorite dish and refining it just a little more each time! Cooking there is always a pleasure: thoughtful hospitality, amazing kitchen and brigade, an electric atmosphere, and guests who truly appreciate the craft behind every plate. This game’s menu (Spurs vs. Man City) is quietly sophisticated, cozy, and deeply soulful—Korean flavors and technique interpreted through a modern British lens. From pickled beetroot ssam wraps with grilled tofu and crisp black rice, to braised pork belly with a rich ssamjang glaze; confit duck mandu dumplings with Asian pear and maesil plum hoisin; spiced rack of lamb with aubergine purée, sesame bok choy, and doenjang dauphinoise; and roasted sirloin paired with slow-cooked kalbi, Yorkshire pudding, ginger-glazed carrots, cavolo nero, and a soy–red wine jus finished with wasabi and horseradish cream. A huge thank you to the brilliant H Club kitchen brigade @regionallondonchef @chefvilliers @christina_celene —your skill, dedication, and teamwork are what make these nights truly special. @tottenhamhotspurstadium @spursofficial #koreanfood #tottenham #chefsofinstagram #korea #football1 week ago via Instagram
