Japanese Potato Salad (A Creamy and Comforting Japanese Side Dish)

A Japanese Comfort Food That Feels Nostalgic and Nourishing

Japanese potato salad is one of those dishes that instantly feels comforting. It is creamy, slightly sweet, savory, and filled with soft potatoes and crunchy vegetables.

I made this recipe for Father’s Day with my kids because it is simple and fun to prepare together. Since it does not require complicated cooking techniques, it is also a wonderful recipe for beginners and children learning how to cook.

Compared to many heavier potato salads, Japanese potato salad has a lighter and fluffier texture. The combination of cucumber, carrot, corn, and egg makes it feel more balanced and refreshing while still being satisfying.

It is one of those side dishes that immediately disappear at a party table.

Why Japanese Potato Salad Feels More Balanced

Japanese potato salad is comforting, but it also includes a variety of nourishing ingredients that create balance in both texture and flavor.

• Potatoes provide steady energy and fullness

• Egg adds protein and richness

• Cucumber and carrot bring freshness and crunch

• Corn adds natural sweetness that kids especially love

• Japanese mayonnaise creates a creamy texture with deep umami flavor

One thing that makes Japanese potato salad unique is the soft, partially mashed texture and the use of Japanese mayo, which gives it a richer yet lighter flavor profile compared to many Western potato salads.

Miwa's Tips

• Mix the sushi vinegar into the potatoes while they are still hot. This helps the potatoes absorb flavor more evenly.

• If you do not have sushi vinegar, you can make your own by combining

  1 tbsp rice vinegar, 1 tbsp sugar, and ⅔ salt.

• Be careful not to overmix the potatoes. Leaving some texture makes Japanese potato salad more comforting and satisfying.

• Use a type of potato which is suitable for salads. In Japan the danshaku potato is my recommendation. Depending on how large your potatoes are, the microwaving time will differ.

• Add mayonnaise only after the potatoes cool slightly. If added while too hot, the flavor and texture can change.

• Potato salad tends to dry slightly after refrigeration. Before serving leftovers, mix in a little more mayonnaise, yogurt, or milk to refresh the texture.

• This recipe is very flexible. You can also add ham, bacon, apple, or onion depending on your preference.

Recommended Side Dish

• Japanese Sweet n' Sour Drum Chicken

• One-pot Wafu Pasta

Storage Time
