Oi gente! In Brazil, potato salad often means the classic mayonnaise-based version with carrots. For a lighter option — and to please anyone avoiding mayo — this tangy vegan potato salad is my go-to. It’s bright, herb-forward and pairs well with many main dishes.

How to make Vegan Potato Salad

1. Cut the potatoes (no need to peel) into halves or quarters so pieces are about 1″ and similar in size. Rinse under cold water to remove excess starch.

2. Place the potatoes in a pot, cover with cold water and season the water generously with salt. Bring to a gentle boil over medium heat and cook until tender when pierced with a fork.

3. While the potatoes cook, prepare the dressing: whisk together olive oil, minced parsley, chopped capers (and a spoon of brine if desired), whole-grain Dijon mustard, white wine vinegar, salt and pepper. Place the thinly sliced onion in a large bowl and set aside.

4. When the potatoes are done, drain and immediately pour the hot potatoes into the bowl with the sliced onions. Let rest for a minute — the residual heat will gently soften and mellow the onion flavor.

5. While the potatoes are still warm, add the mustard vinaigrette and toss gently to coat. Dressing the potatoes while warm helps them absorb flavor more effectively.

6. Allow the salad to cool to room temperature, stir again a couple of times, then cover and refrigerate. Serve chilled or at room temperature — both work well.

Frequently Asked Questions

Do you leave skin on for potato salad?

Yes. With small baby yellow potatoes the skins stay on — they add texture, color and save time.

What kind of potatoes are best for potato salad?

Waxy varieties such as Yukon Gold, Yellow Finn, red potatoes or Dutch gold hold their shape well when boiled and work best.

Is it better to boil potatoes whole or cut up?

Cutting potatoes before boiling speeds cooking and avoids handling hot whole potatoes.
