Japanese Potato Salad, known as poteto sarada, is a beloved yoshoku staple that offers a unique twist on the classic Western side dish. Unlike its American counterpart, this version features a creamy, semi-mashed texture combined with a vibrant mix of crunchy vegetables like cucumbers and carrots. The signature element is the use of Japanese mayonnaise, which provides a rich, umami-packed flavor profile that is both slightly sweet and tangier than traditional mayo.

This recipe is incredibly versatile and serves as the perfect accompaniment to bento boxes, summer barbecues, or even as a filling for a soft bread sandwich. By adding rice vinegar to the potatoes while they are still warm, you ensure every bite is infused with a bright acidity that balances the creaminess of the dressing. Whether you are looking for a refreshing picnic side or a comforting home-cooked dish, this Japanese-style salad delivers a sophisticated blend of textures and flavors that will quickly become a family favorite.

Key Ingredients

• 900 grams Yukon Gold potatoes, peeled and chopped
• 1/3 cup Japanese mayonnaise (Kewpie brand)
• 1/8 cup rice vinegar
• 4 large eggs, hard-boiled and chopped
• 1/3 English cucumber, thinly sliced
• 1/4 onion, thinly sliced
• 1/4 cup carrots, diced
• 1 teaspoon salt
• 1/4 teaspoon black pepper

Step-by-Step Instructions

1. Place the chopped potatoes and carrots in a pot of cold salted water and bring to a boil.
2. Simmer for 15-20 minutes until the vegetables are tender, then drain the water completely.
3. While the potatoes are hot, lightly mash them with a fork or masher, leaving some small chunks for texture.
4. Stir in the rice vinegar, salt, and black pepper while the mash is still warm to allow flavors to absorb.
5. In a small bowl, toss the sliced cucumbers and onions with a pinch of salt and let them sit for 10 minutes to draw out moisture.
6. Squeeze the excess liquid out of the cucumbers and onions and set them aside.
7. Once the potato mixture has cooled, add the Japanese mayonnaise, chopped hard-boiled eggs, cucumber, and onion.
8. Gently fold all ingredients together until evenly coated and creamy.
9. Refrigerate the salad for at least 30-60 minutes before serving to allow the flavors to meld.
