Japanese Potato Salad Ingredients
A simply delicious Japanese potato salad dish calls for the following ingredients:
- Potatoes
- Persian cucumber
- Shallot (or red onion)
- Salt
- Imitation crab meat
Homemade creamy dressing is made with Japanese mayonnaise, condensed milk, salt, and ground black pepper.

How to Make Japanese Potato Salad?
First, peel and cut the potatoes into bite-sized pieces. Make sure to cut them into roughly the same size, so they cook through evenly. You can either boil or steam them until soft and tender.
Second, gently mash the potatoes and leave some small chunks for texture. Set aside to cool down.

Meanwhile, prepare Persian cucumber slices and shallot slices by soaking them in salted water for a few minutes. Then, drain and squeeze them hard to remove the excess water.

Finally, combine all prepared veggies and imitation crab meat with Japanese mayonnaise and condensed milk, then add salt and ground black pepper to taste.

Cook’s Tips
For the best result, please follow my tips:
- To make a creamy potato salad, cook or steam the potatoes until soft and tender. However, we don’t want the potatoes to be overcooked, which will be too moist and easily fall apart.
- Mash the potatoes until smooth but leave a few small chunks for the perfect texture.
- Soaking cucumber and shallot slices in salted water will help remove the pungency from shallot (or onion) and make cucumber crunchier.

Frequently Asked Question
Japanese mayonnaise (Kewpie) is the key to this recipe, adding a unique flavor to this irreplaceable dish. Unlike regular mayonnaise made with whole egg and white vinegar, Japanese mayonnaise contains only egg yolks mixed with rice or apple cider vinegar, which adds a tangy and savory taste to the dish.
Any potato works for this recipe. I recommend using waxy potatoes, such as red potato, white potato, or Yukon gold potato. It helps to create a creamy texture for the dish.

Recipe Notes
Waxy potatoes are best here. Try red or Yukon gold for the best flavor.
Love this recipe, it’s delicious. I haven’t tried it yet but for people having trouble finding Japanese Mayonnaise you might want to try Kraft Miracle Whip. It has a similar taste to Kewpie Mayo & is readily available, not to mention cheaper.
Thanks for your suggestion!
“Fake” crab meat! Seriously, it has NO taste at all.
This is how it’s made. Japanese uses a lot of that. If you don’t like it you can just skip.
I love immitation crab meat – we use it in alot of recipes.
Hi! This looks so good. What kind of condensed milk do you use?
Thank you!
Any brand of condensed milk is fine.
Is that sweetened condensed milk?
Yes.
What is in Japanese mayonnaise? Never heard of it before. Thank you have a great day
Japanese mayo is Kewpie brand mayo. You can just use regular mayo.
love this dressing. I added more condensed milk. Have been looking for a good crab salad -the addition of potatoes makes it even better. thanks
Awesome thanks!
