What’s In Japanese Potato Salad?
The magic of this salad lies in its creamy texture and balanced flavors. Here’s what you’ll need:
- Potatoes: Yukon Gold or Russet potatoes work best for their creamy texture when mashed.
- Japanese Mayonnaise: Sweeter and tangier than regular mayo, it’s the key to authentic flavor.
- Cucumber & Carrots: Add a refreshing crunch.
- Ham or Bacon: For a savory, umami touch (optional for vegetarians).
- Rice Vinegar: Balances the richness with a mild acidity.
- Salt & Sugar: Enhance the overall flavor profile.

How To Make Japanese Potato Salad
This recipe is simple but requires a few key steps to achieve the perfect texture and flavor. Here’s how to make it:

- Drain and mash while still warm, leaving some small chunks for texture.
Step 2: Prep the Vegetables
- Thinly slice the cucumber and carrots. Sprinkle with salt and let sit for 10 minutes to draw out excess moisture. Squeeze dry.
- If using ham, cut into small strips.
Step 3: Mix the Salad
- In a large bowl, combine the mashed potatoes, vegetables, and ham.
- Add Japanese mayo, rice vinegar, sugar, and salt. Mix gently until well combined.
Step 4: Chill and Serve
