If you’re looking for a standout summer recipe, this Grilled Potato Salad with Scallion Vinaigrette deserves a place on your table.
Why Grilled Potato Salad Is Better Than Traditional Versions
The difference between regular potato salad and Grilled Potato Salad with Grilled Scallion Vinaigrette comes down to texture and flavor depth.

Step-by-Step Recipe Instructions
Step 1: Par-Boil the Potatoes
Place potatoes in a pot of room temperature salted water. Bring to a boil, then reduce to simmer. Cook for about 15 minutes until just fork-tender. They should be soft inside but still firm enough to grill.
Drain and allow them to cool slightly before slicing lengthwise.
Step 2: Preheat the Grill
Heat your grill or grill pan to medium heat. Lightly oil the grates to prevent sticking.
Step 3: Prepare the Grilled Scallion Vinaigrette
The dressing is what truly defines Grilled Potato Salad with Scallion Vinaigrette.
- Toss scallions with a little olive oil and salt.
- Grill until lightly charred (about 2 minutes).
- Transfer to a food processor.
- Add vinegar, miso, mustard, sriracha, and water.
- Blend until smooth.
- Add cilantro and remaining oil, pulse again.
The result is smoky, tangy, savory, and slightly spicy — a perfect complement to grilled potatoes.
Step 4: Grill the Potatoes
Toss sliced potatoes in olive oil, salt, and pepper.
Place cut side down on the grill for 5–6 minutes until grill marks form. Flip and cook another 5 minutes until crispy and golden.
The charred texture is what makes Grilled Potato Salad with Scallion Vinaigrette stand out from any ordinary potato salad.
Step 5: Grill the Blueberries
Place blueberries on foil, drizzle with olive oil, and grill for 2 minutes until they darken and slightly burst.
They add a subtle sweetness that beautifully balances the savory dressing.
Step 6: Assemble the Salad
Arrange grilled potatoes on a platter. Spoon generous amounts of the vinaigrette over them. Add grilled blueberries, mint leaves, chopped scallions, and pickled onions. Finish with another drizzle of dressing.
Serve warm or at room temperature for the best flavor experience.
