Japanese Sweet Potato Salad

November 12, 2025 by Marc Matsumoto Leave a Comment

A towering mound of Japanese Sweet Potato Salad.

In Japan, potato salad isn’t so much a recipe as it is a concept. It’s flexible, and often made with other starchy vegetables like sweet potatoes or kabocha. Every cook has their version, which is why deli counters are lined with colorful riffs on the same comforting idea: a side that’s both a veggie and a starch, creamy and satisfying.

When autumn rolls around, I reach for satsuma imo, or Japanese sweet potatoes. They have a mellow sweetness and silky texture that make them a perfect base. Instead of mayo, I like to use Greek-style yogurt. It’s still creamy, but the tang cuts through the sweetness and adds a bit of cheese-like depth. That balance makes each bite rich and creamy without feeling heavy.

To round it out, I mix in crumbled walnuts for crunch and bits of dry-cured ham for a savory pop. The salty ham wakes everything up, and the nuts add just enough texture to keep things interesting. Like most good potato salads, this one’s even better after it rests. That makes it perfect for bento lunches, meal prep, or an easy make-ahead Thanksgiving side.

Welcome!

I started No Recipes back in 2007 as a place to share original dishes I'd created with friends. It's since evolved into something much bigger than I could have imagined, but as it grew, the focus shifted from inventing dishes to improving classics. In the spirit of how No Recipes began, I'm bringing back my weekly original recipes for all of my supporters and friends!
