Ingredients
For the Potato Salad
1½ lb baby red, white, and purple waxy potatoes, halved or cubed
½ cup cornichons or small dill pickles, whole or sliced
¼ cup fresh dill, finely chopped
¼ cup fresh parsley, finely chopped
2 tbsp fresh chives, finely chopped
3 green onions, thinly sliced
1 small shallot, finely minced, optional
For the Mustard Vinaigrette
2 tbsp Dijon mustard
1 tbsp whole-grain mustard
¼ cup extra-virgin olive oil
2 tbsp red wine vinegar or champagne vinegar
2 tbsp cornichon or pickle juice
½ tsp sea salt, or to taste
¼ tsp freshly cracked black pepper, or to taste
Instructions
Prepare the Potatoes
Wash the potatoes thoroughly and remove any damaged spots. If using larger baby potatoes, cut them into halves or bite-sized pieces so they cook evenly.
Place the potatoes in a large saucepan and cover them with cold water. Add a generous pinch of salt to the water.
Bring the water to a boil, then reduce the heat to a gentle simmer. Cook the potatoes for approximately 10 to 15 minutes, depending on their size.
The potatoes should be tender when pierced with a fork but should still hold their shape. Avoid overcooking them because soft potatoes can become mushy when tossed with the dressing.
Drain and Cool the Potatoes
Drain the potatoes thoroughly once they are cooked. Allow them to cool for several minutes.
For the best flavor, toss the warm potatoes with the vinaigrette while they are still slightly warm. Warm potatoes absorb the dressing more effectively, allowing the mustard and vinegar flavors to penetrate the potatoes.
Make the Mustard Vinaigrette
In a small bowl, whisk together the Dijon mustard and whole-grain mustard.
Add the red wine vinegar or champagne vinegar and cornichon juice. Slowly drizzle in the extra-virgin olive oil while whisking continuously.
Continue whisking until the dressing becomes smooth and lightly emulsified. Season with sea salt and freshly cracked black pepper.
Taste the vinaigrette and adjust the seasoning if needed. Add a little more vinegar for acidity or pickle juice for extra tang.
Combine the Salad
Place the warm potatoes in a large serving bowl. Pour the mustard vinaigrette over them and gently toss until the potatoes are evenly coated.
Add the sliced cornichons, fresh dill, parsley, chives, green onions, and optional minced shallot.
Fold everything together gently so the potatoes remain intact.
Rest and Serve
Allow the potato salad to rest for at least 10 to 15 minutes before serving. This gives the potatoes time to absorb the vinaigrette and allows the fresh herbs and pickles to blend into the salad.
Serve warm, at room temperature, or lightly chilled. Before serving, taste again and add additional salt, pepper, vinegar, or herbs if desired.
Tips for the Best French Potato Salad
Use Waxy Potatoes
Baby red, white, and purple waxy potatoes are ideal because they remain firm after cooking. Avoid very starchy potatoes if you want a salad with distinct potato pieces.
Do Not Overcook the Potatoes
The potatoes should be tender but firm enough to hold their shape. Start checking them with a fork around the 10-minute mark.
Dress the Potatoes While Warm
Adding the vinaigrette while the potatoes are still warm helps them absorb the dressing and creates a much more flavorful salad.
Use Fresh Herbs
Fresh dill, parsley, and chives provide a bright flavor that dried herbs cannot fully replicate. Add the herbs after cooking to preserve their freshness.
Adjust the Vinaigrette to Taste
Mustard and vinegar vary in strength, so taste the dressing before adding it to the potatoes. Adjust the acidity, salt, and pepper according to your preference.
Let the Salad Rest
Allowing the finished salad to rest for several minutes gives the flavors time to develop and makes the potatoes even more flavorful.
Variations
Creamy French Potato Salad
For a creamier version, stir a spoonful of Greek yogurt or crème fraîche into the vinaigrette before tossing it with the potatoes.
Tarragon Herb Salad
Replace some or all of the dill with fresh tarragon for a classic French herb flavor with a slightly sweet, aromatic character.
Bacon Potato Salad
Add crispy cooked bacon pieces for a smoky, savory variation. The bacon pairs particularly well with Dijon mustard and cornichons.
Green Bean Addition
Add lightly blanched green beans for extra color, texture, and freshness.
Mediterranean Twist
Add chopped roasted red peppers, olives, and a little crumbled feta for a Mediterranean-inspired variation.
Q&A
Can I make French potato salad ahead of time?
Yes. This potato salad can be prepared several hours ahead and kept refrigerated. Allow it to sit at room temperature briefly before serving so the flavors and texture are at their best.
Should French potato salad be served hot or cold?
It can be served warm, at room temperature, or chilled. Serving it slightly warm or at room temperature allows the mustard vinaigrette and herbs to be especially aromatic.
What potatoes are best for French potato salad?
Waxy baby potatoes, including red, white, and purple varieties, are excellent choices because they hold their shape well after cooking.
Why add the dressing while the potatoes are warm?
Warm potatoes absorb the vinaigrette more easily. This allows the mustard, vinegar, olive oil, and pickle juice to flavor the potatoes from the inside rather than simply coating the surface.
Can I use regular pickles instead of cornichons?
Yes. Small dill pickles can be used if cornichons are unavailable. Choose a crisp pickle with a bright, tangy flavor.
How long does French potato salad last in the refrigerator?
Stored in an airtight container, it can generally be enjoyed for about 3 days. The herbs may lose some freshness over time, so adding a little fresh parsley or chives before serving can brighten it.
Can I make the vinaigrette in advance?
Yes. The vinaigrette can be whisked together several hours ahead and refrigerated. Bring it closer to room temperature and whisk again before using.
