Japanese Potato Salad (Poteto Sarada) is a beloved side dish found in homes, izakaya pubs, supermarkets, bento boxes, and convenience stores throughout Japan. Unlike many Western potato salads, the Japanese version is creamier, slightly sweeter, and packed with crunchy vegetables such as cucumber, carrots, and onions. It's typically dressed with rich Japanese mayonnaise, giving it a smooth, tangy, and umami-rich flavor.

Whether served alongside fried dishes like tonkatsu and karaage or enjoyed as a light lunch, Japanese Potato Salad is simple to prepare and full of comforting flavors.

What Is Japanese Potato Salad?

Japanese Potato Salad is made by mashing boiled potatoes while leaving some small chunks for texture. Fresh vegetables, boiled eggs, and sometimes ham are mixed into the potatoes, then combined with Japanese mayonnaise and simple seasonings. The result is a creamy salad with a perfect balance of softness, crunch, and savory flavor.

Unlike traditional Western potato salad, this version uses Japanese mayonnaise, which is richer and slightly sweeter thanks to egg yolks and rice vinegar.

Ingredients

For the Salad

  • 600 g Yukon Gold or Russet potatoes, peeled and cut into chunks
  • 1 medium carrot, thinly sliced
  • 1 small cucumber, thinly sliced
  • ½ small onion, very thinly sliced
  • 2 hard-boiled eggs, chopped
  • 80 g cooked ham, diced (optional)
  • 4 tablespoons Japanese mayonnaise
  • 1 teaspoon rice vinegar
  • ½ teaspoon Dijon mustard (optional)
  • Salt, to taste
  • Freshly ground black pepper, to taste

For Garnish

  • Fresh parsley, chopped
  • Extra black pepper
  • Cucumber slices
  • Cherry tomatoes

Kitchen Equipment

  • Large saucepan
  • Mixing bowls
  • Potato masher or fork
  • Knife
  • Cutting board
  • Colander

Step 1: Cook the Potatoes

Place the potatoes in a saucepan and cover with cold water.

Bring to a boil and cook for 15–20 minutes, or until fork-tender.

Drain well and let excess moisture evaporate for 2–3 minutes.

Lightly mash the potatoes, leaving a few chunks for texture.

Step 2: Prepare the Vegetables

Boil the carrot slices for 2–3 minutes until just tender.

Drain and cool.

Sprinkle the cucumber and onion slices with a little salt and let them sit for 10 minutes.

Squeeze out the excess moisture using your hands or a clean kitchen towel.

Step 3: Mix the Salad

Add the carrots, cucumber, onion, chopped eggs, and diced ham (if using) to the mashed potatoes.

Mix gently to combine.

Step 4: Add the Dressing

Stir together:

  • Japanese mayonnaise
  • Rice vinegar
  • Dijon mustard (optional)

Fold the dressing into the potato mixture.

Season with salt and freshly ground black pepper to taste.

Mix until creamy but not completely smooth.

Step 5: Chill

Cover the salad and refrigerate for 30–60 minutes.

Chilling allows the flavors to blend and improves the texture.

Tips for Perfect Japanese Potato Salad

  • Use starchy potatoes for a fluffy texture.
  • Mash the potatoes while they are still warm.
  • Remove excess moisture from the cucumber and onion to keep the salad creamy.
  • Use authentic Japanese mayonnaise for the best flavor.
  • Chill before serving for a richer taste.
