What is a picnic potato salad?! It’s a delicious side that’s loaded with other chunky vegetables, and doused in a flavorful vinaigrette. No mayo is needed! The trick to this simple potato salad is in the preparation. Everything is tossed together while the potatoes are still warm, which allows the flavors to fully absorb. You can even serve it warm, but we like it after refrigeration best.
Dairy-Free Picnic Potato Salad made with Everything but Mayo!
The recipe below was originally shared with us by the Idaho Potato Commission a decade ago, but we’ve recently updated it. I also have new tips and ingredient options for this dairy-free picnic potato salad in the FAQs below.
Can I Make this Picnic Potato Salad Ahead?
You can make it a day ahead, and it will keep for a few days in the refrigerator. The flavors will actually develop a bit more as it chills. Cover it with plastic wrap of put it in an airtight container and refrigerate until ready to serve.
What Mustard Do You Recommend?
It’s really your choice. Dijon mustard is my favorite in this red wine vinaigrette. But you can use yellow mustard, brown mustard, or a fancy mustard, if that’s what you have on hand.
What Can I Substitute for the Red Wine Vinegar?
The closest substitute will be white wine vinegar. Balsamic vinegar, apple cider vinegar, or white vinegar will also work well in this recipe, but each will create a slightly different flavor.
What are Idaho Potatoes?
This is another name for russet potatoes. You could alternatively use Yukon gold or other yellow potatoes to make this dairy-free mustard potato salad. Red potatoes are also a good option. They are firmer and waxier, but tend to work well with vinaigrettes and chunky add ins, like green beans and olives.
How is that “Cheese” Star Cut so Perfectly?
It’s cut with a star cookie cutter. It’s cute, isn’t it?! If you’re artistic, you can free form cut stars from dairy-free cheddar cheese slices, but I need cutters!

Umm…what mayo has dairy in it? to make mayo, it’s eggs, oil, vinegar/lemon juice, salt and pepper…what dairy?
You are already adding eggs in, so it’s not going egg free….I don’t get it. I am sure this recipe is delicious! Looks fabulous, but I don’t know of any mayo that has dairy in it….
Hi Angelica, I didn’t say anything about mayo containing dairy, because it doesn’t. Eating dairy-free isn’t only about substitute recipes! Many recipes are delicious and dairy-free, and not all potato salads need mayo! Yes, mayo is dairy-free, but why not try a mayo-free one?? If you use vegan mayo, you can skip the eggs for a vegan potato salad. Enjoy the recipe!
