Why this recipe works

  • Cold, boiled potatoes… hard to beat straight off the bat!
  • Vegetable oil, vinegar, water & dijon mustard combine to create a delicious creamy dressing – you won’t believe there’s actually no dairy or mayo in there!
  • A good dose of dijon mustard gives the salad a nice spicy kick
  • Capers add saltiness & texture
  • Shallots add a bite & a little bit of crunch (we love those layers of texture!)

What is French potato salad?

French potato salad is a cold or lukewarm vegan potato salad that’s made from boiled potatoes that have been allowed to cool partly or completely. The potatoes are then mixed with some kind of onion (usually shallots, like for this recipe, or red onion) and covered in a deliciously creamy dijon mustard vinaigrette. Perfect to pair with grilled meat, halloumi, fish, or serve as part of a buffet.

Without mayo, dairy, egg and gluten it’s an allergy friendly side dish that most pople can eat. Sensitive to raw onions? Just skip them, or use less – it’s delicious anyway.

For my version I’ve added capers (you could also add chopped pickles) which is maybe not all that traditional, but I love to get that extra bit of saltiness & crunch. For a non-vegan, super indulgent version you might want to try switching these for bacon…

Is potato salad healthy?

Whether or not it’s healthy, is really up to you – what you consider healthy, and which kind you choose.

Potatoes are a nutrient-rich carb, which makes them better for you than a lot of other carbs. And the Glycemic Index (GI) of cold, boiled potatoes is lower (hence, better for you) than for warm, boiled potatoes. So as carbs go – cold potatoes are a pretty good choice.

Now some potato salads have loads of mayo or other fatty ingredients – this one does not. So considering that, this is a good choice for your healthy lifestyle. And compared to other buffet friendly foods like french fries, creamy & buttery mashed potatoes, potato chips and pasta salad… let’s not even go there, OK? Just eat the French potato salad and enjoy.

Can potato salad be made ahead?

This recipe can be made several days in advance and is best when made at least an hour before serving. So go ahead and make it the night or day before, or even 2 days in advance – just cover it up good and keep it in the fridge.

Other potato salad versions with mayonnaise can be more sensitive, so if making it ahead of time a French version is a good choice.

Expert tips

  • Always taste the dressing before adding to the salad, and adjust to taste.
  • Add half of the dijon first, if you’re not sure how spicy you like it. Taste the vinaigrette, then add more if needed before pouring over the salad.
  • Use a neutral tasting oil – ie, no olive il for this one. Unless you really, really, really want that olive oil taste – but just keep in mind, it will taste a lot like olive oil.
  • Switch it up with different types of vinegar and onion – my favorite version is red wine vinegar and shallots, but another delicious option is apple cider vinegar and red onion – and I’m sure you’ll find your own favorite way of making it.
  • Chop your onion really well to avoid biting into a big piece of onion – it should just be there as a nice backdrop, not a main player.
