There’s a moment in every great meal where a side dish quietly steals the show. For me, that moment often comes with a scoop of Korean Potato Salad. It’s not the picnic-style salad you might remember.
This version is a study in contrasts: luxuriously creamy yet packed with little bursts of sweet apple and crunchy vegetables, all brought together with a subtle, sweet-tangy dressing. It’s a staple banchan (side dish) in Korean cuisine, but it’s just as at home next to your weeknight grilled chicken or as a standout at a potluck. Having tested this recipe multiple times in my own kitchen, I’ve honed a method that delivers that signature creamy texture and balanced flavor every single time.
Let’s make a side dish you’ll want to make again and again.
This isn’t your average potato salad. Here’s what makes this version a must-try:
- Perfect Texture Balance: Enjoy a supremely creamy base from riced potatoes, punctuated by the crisp crunch of cucumber, carrot, and apple.
- Sweet & Tangy Flavor Profile: A touch of sugar and vinegar creates a uniquely Korean sweet-savory dressing that’s incredibly moreish.
- Surprisingly Refreshing: The addition of salted cucumber and apple makes this salad feel light and refreshing, not heavy or starchy.
- Versatile Side Dish: It pairs perfectly with everything from Korean BBQ (galbi, bulgogi) to Western-style grilled meats and sandwiches.
- Make-Ahead Friendly: The flavors improve after a few hours in the fridge, making it ideal for prepping ahead for gatherings.
- Simple Techniques: No fancy skills required—just some boiling, dicing, and gentle folding.
Ingredients You’ll Need
- Let’s gather our ingredients. This recipe is a beautiful example of how simple components, treated with care, create something greater than the sum of its parts. The key is in the balance: starchy potatoes, creamy dressing, and fresh, crunchy mix-ins.
- Yukon Gold Potatoes: Their buttery flavor and medium starch content make them ideal. They mash up creamy but hold their structure when mixed.
- English Cucumber: We salt and squeeze it to remove water. This is a non-negotiable step to prevent a watery salad. Believe me, it makes all the difference.
- Carrot & Yellow Onion: They add essential color, sweetness, and a gentle bite. Dice them small so they distribute evenly.
- Fuji or Honeycrisp Apple: The secret ingredient! It adds a fresh, sweet crunch that is quintessential to the Korean style. Peel it to avoid bits of skin in the creamy mix.
- Hard-Boiled Eggs: They contribute richness and body. We’ll use most of them in the salad and save one yolk for the classic, beautiful garnish.
- Kewpie Mayonnaise: This Japanese mayo is sweeter, tangier, and creamier than most American brands, thanks to egg yolks and rice vinegar. It’s traditional here, but regular mayo works with a slight adjustment in vinegar.
- Milk or Heavy Cream: Added to the hot potatoes, this creates an incredibly smooth and lush base. Whole milk is fine, but cream is decadent.
- Sugar, Vinegar, Salt & Pepper: This is our seasoning trifecta. The sugar isn’t optional—it’s what gives the salad its distinctive sweet note. Rice vinegar is mild, but apple cider vinegar is a great substitute.

Kitchen Equipment Needed
You don’t need any specialized gear. A medium pot for boiling the potatoes and a colander for draining are essential. A potato ricer is my professional tool of choice for the fluffiest, lump-free mash, but a standard potato masher works perfectly well—just aim for mostly smooth.
You’ll need a chef’s knife and cutting board for dicing, a mixing bowl, and a fine-mesh sieve for that elegant sieved-egg-yolk topping. A clean kitchen towel is crucial for wringing out the cucumber.
How to Make Korean Potato Salad Recipe
Step 1: Cook and Dry the Potatoes
Start by boiling your peeled, cubed potatoes in well-salted cold water. Starting them in cold water ensures they cook evenly from the outside in. Once tender, drain them thoroughly in a colander and let them sit for a full 5 minutes to steam off any residual surface moisture.
This step is your first defense against a watery, loose salad. Tip from me: overcooking leads to waterlogged potatoes, so test them at the 12-minute mark.
Step 2: Prep and Dehydrate the Cucumber
While the potatoes cook, tackle the cucumber. After dicing, toss it with salt and let it sit. The salt pulls the water out through osmosis.
After 10 minutes, rinse off the excess salt and then squeeze the life out of those cubes in a clean towel. You’ll be amazed at how much water comes out. This concentrated cucumber flavor and crunch will now integrate beautifully without diluting your dressing.
Step 3: Create the Creamy Potato Base
Here’s where technique matters. Return the hot, dry potatoes to the warm pot. Mash or rice them while they’re still very hot.
Then, immediately stir in the milk or cream. The heat helps the potato starch absorb the liquid, creating a cohesive, almost paste-like base that won’t separate later. This is the foundation for that signature creamy texture.
Step 4: Combine and Season
Now for the fun part: bringing it all together. To the warm potato base, add the mayo, sugar, vinegar, salt, and pepper. Fold gently.
Then, add your colorful array of diced vegetables, apple, and the chopped hard-boiled eggs. Fold just until everything is evenly distributed. Be gentle to keep some texture.
Now, taste. This is your chance to adjust the balance. Want it sweeter?
Add a pinch more sugar. Need more tang? A dash of vinegar.
Step 5: Garnish, Chill, and Serve
Transfer your salad to a serving dish. For that authentic deli-style look, smooth the top with a spatula. Take the reserved hard-boiled egg yolk and press it through a fine-mesh sieve directly over the salad—it creates a gorgeous, sunny dusting.
Cover and refrigerate for at least an hour. This chilling time is not just for temperature; it allows the sugar to dissolve fully and the flavors to marry into that distinctive, harmonious taste. Step back and admire your creation before serving it cold.
A few insights from years of testing will guarantee your success:
- Potato Choice is Key: Yukon Golds are the perfect hybrid. Russets can be too fluffy and dry, while red potatoes can be too waxy. Yukons give you creamy cohesion.
- The Hot Mash Principle: Adding the cold dairy to the hot potatoes isn’t just about absorption; it also helps cool the potatoes quickly to a safe temperature before adding the mayo, which can separate if heated.
- Dice Consistently: Aim for a uniform 1/4-inch dice on all your add-ins (cucumber, carrot, onion, apple). This ensures every bite has the perfect mix of flavors and textures.
- Season in Layers: Salting the boiling water, salting the cucumber, and seasoning the dressing are all separate seasoning events. Taste at the final mix stage and adjust carefully.
- Kewpie vs. Regular Mayo: If you use regular American mayonnaise, consider adding an extra teaspoon of vinegar and a teaspoon more sugar to approximate Kewpie’s unique profile.
Recipe Variations & Customizations
- This recipe is wonderfully adaptable. Here are some tested variations:
- Spicy Version: Add 1-2 tablespoons of gochujang (Korean chili paste) to the dressing for a sweet, spicy, and deeply flavorful kick.
- Protein Boost: Fold in 1/2 cup of diced ham or crispy bacon bits for a heartier salad that can serve as a light main course.
- Vegan/Dairy-Free: Use vegan mayonnaise and substitute the milk with unsweetened, unflavored plant-based milk (soy or oat work well). Omit the eggs or use a firm tofu scramble.
- Extra Crunch: Add 1/4 cup of finely chopped water chestnuts or jicama for an additional layer of crisp texture.
- Herbaceous Twist: Stir in 2 tablespoons of finely chopped fresh chives or parsley just before serving for a bright, fresh note.
- Sweet Corn Addition: A 1/2 cup of sweet corn kernels (thawed if frozen) adds a lovely pop of sweetness and color, common in some Korean versions.
What to Serve With This Recipe
Korean Potato Salad is incredibly versatile. Traditionally, it’s part of a spread of banchan (small side dishes) alongside rice, soup, and a main protein like Galbi (marinated short ribs) or Bulgogi (marinated beef). For a fusion approach, it’s fantastic with grilled chicken, pan-seared fish, or even burgers and hot dogs—it will be the most memorable side at your barbecue.
It also makes an excellent filling for sandwiches or a topping for lettuce cups. For beverages, pair it with a light, crisp lager, iced barley tea, or a dry sparkling water.
Storage & Make-Ahead Instructions
- This salad is an excellent make-ahead dish.
- Refrigeration: Store in an airtight container in the refrigerator for up to 3 days. The flavors will continue to meld and improve over the first 24 hours.
- Avoid Freezing: I do not recommend freezing this salad. The mayonnaise and dairy will separate upon thawing, and the vegetables will become mushy and release water, creating a very unappealing texture.
- Make-Ahead Strategy: You can fully prepare the salad 1 day in advance. Wait to add the sieved egg yolk garnish until just before serving, as it can darken slightly in the fridge. If the salad seems a bit stiff after chilling, let it sit at room temperature for 15 minutes and give it one gentle stir before serving.
- Food Safety: Because it contains eggs and dairy, always keep it refrigerated and do not leave it out at room temperature for more than 2 hours.
Frequently Asked Questions
Q: Can I use regular mayonnaise instead of Kewpie?
A: Absolutely. The flavor will be slightly different, as Kewpie is sweeter and tangier. To compensate, add an extra teaspoon of sugar and an extra teaspoon of rice vinegar to your dressing when using regular mayo.
Q: Why do I need to salt and squeeze the cucumber?
A: This step removes excess water that would otherwise seep out into the salad after mixing, making it watery and diluting the creamy dressing. It’s a crucial technique for texture.
Q: Can I make this without eggs?
A: Yes, you can omit the eggs. The salad will be slightly less rich, but still delicious. You can add a little extra mayo or a spoonful of plain yogurt to maintain creaminess.
Q: My potato salad seems too stiff. What did I do wrong?
A: You likely over-mashed the potatoes or didn’t add enough liquid. Next time, ensure you add the full amount of milk/cream to the hot potatoes. For this batch, you can gently fold in a tablespoon or two of extra milk or mayo to loosen it.
Q: How far in advance can I boil the eggs?
A: You can hard-boil the eggs up to 5 days in advance. Store them peeled or unpeeled in the refrigerator until you’re ready to make the salad.
Q: Is there a way to make this lower in sugar?
A: Yes, you can reduce the sugar to 1 tablespoon, or use a granulated sugar substitute that measures 1:1 like erythritol. The traditional taste is sweet, but it’s adaptable to your preference.
Q: Can I use a food processor to mash the potatoes?
A: I strongly advise against it. Food processors break down the potato starch too aggressively, resulting in a gummy, gluey texture. A ricer, masher, or even a fork is the right tool for this job.
Q: What’s the best way to dice the onion without it being too pungent?
A: Soaking the diced onion in cold water for 10 minutes after dicing will mellow its sharp bite. Just be sure to drain and pat it dry thoroughly before adding it to the salad.

Korean Potato Salad
Equipment
- Medium pot
- Colander
- Potato ricer or masher
- Mixing bowls
- Chef’s knife and cutting board
- Fine-mesh sieve (for garnish)
Ingredients
- 2 pounds Yukon Gold potatoes peeled and cut into 1-inch chunks
- 1 tsp salt for boiling water
- 1/2 cup English cucumber seeds removed, finely diced
- 1/2 tsp salt for salting cucumber
- 1/2 cup carrot finely diced
- 1/2 cup yellow onion finely diced
- 1/2 cup Fuji or Honeycrisp apple peeled and finely diced
- 3 large hard-boiled eggs 2 chopped, 1 yolk reserved for garnish
- 1/2 cup whole milk or heavy cream room temperature
- 1/2 cup Kewpie mayonnaise or regular mayonnaise
- 2 tbsp granulated sugar or to taste
- 1 tbsp vinegar rice vinegar or apple cider vinegar
- 1/2 tsp fine sea salt or to taste
- 1/4 tsp black pepper freshly ground
Instructions
- Place the peeled and cubed potatoes in a medium pot. Cover with cold water by 1 inch and add 1 teaspoon of salt. Bring to a boil over high heat, then reduce to a simmer. Cook for 12-15 minutes, or until a fork pierces the potato easily with no resistance. Drain well in a colander and let them steam-dry for 5 minutes. This step is crucial to avoid a watery salad.
- While the potatoes cook, prepare the vegetables. Toss the diced cucumber with 1/2 teaspoon of salt and let it sit in a colander for 10 minutes. This draws out excess water. Rinse briefly and squeeze firmly in a clean kitchen towel to remove as much moisture as possible. Trust me, this keeps your salad creamy, not soggy.
- Return the dried, hot potatoes to the warm pot. Using a potato ricer or masher, mash them until mostly smooth with a few small lumps for texture. While the potatoes are still hot, immediately stir in the milk or cream. The heat helps the potatoes absorb the liquid, creating a luxuriously smooth base.
- Add the Kewpie mayo, sugar, vinegar, salt, and pepper to the warm potato mixture. Fold gently until combined. Now, fold in the prepared cucumber, diced carrot, onion, apple, and the two chopped hard-boiled eggs. Be gentle to maintain some texture. Taste and adjust seasoning, adding more sugar, salt, or vinegar to your preference.
- Transfer the salad to a serving bowl. For the classic finish, press the mixture down lightly with a spatula to create a smooth top. Push the reserved hard-boiled egg yolk through a fine-mesh sieve over the top for a beautiful yellow garnish. Cover and chill for at least 1 hour before serving to allow the flavors to meld.
