Jacques's French Potato Salad

This classic French potato salad is a sophisticated departure from the heavy, mayonnaise-based versions often found at picnics. By dressing small, waxy potatoes in a vibrant mixture of white wine, Dijon mustard, and high-quality extra-virgin olive oil while they are still warm, the tubers absorb the bright flavours beautifully. The addition of softened onions, garlic, and a generous handful of fresh herbs like tarragon and basil creates a fragrant and aromatic savoury dish.

As a versatile vegetarian side, this recipe is perfect for spring luncheons or as an elegant accompaniment to grilled fish or roasted meats. Serving the salad on a bed of crisp radicchio leaves adds a pleasant bitter contrast and a pop of colour, while the chopped egg garnish provides a traditional finish. It is best enjoyed warm or at room temperature to ensure the olive oil and herb infusions remain at their most flavourful.

Ingredients for Jacques's French Potato Salad

  • 900g fingerling potatoes or other small waxy potatoes

  • 120ml or so extra-virgin olive oil

  • 120ml 1/4-inch slices of spring onion, green and white parts

  • 80g chopped onion

  • 3 cloves garlic, mashed and coarsely chopped (1 1/2 teaspoons )

  • 80ml white wine

  • 1 1/2 tablespoons Dijon-style mustard

  • 2 to 3 tablespoons chopped chives

  • 2 tablespoons or more coarsely chopped fresh green or purple basil, fresh tarragon, or parsley

  • 1 teaspoon kosher salt, plus more if needed

  • 1/2 teaspoons freshly cracked black pepper (coarse), plus more if needed

  • Large radicchio leaves, about 6, from the outside of the head

  • 1 or 2 hard-boiled eggs, coarsely chopped

  • Chopped fresh parsley

Scrub the potatoes and put them, whole, in a saucepan with water to cover by 1/2 inch. Bring the water to a boil, reduce the heat, and cook the potatoes gently until they are just tender and can be pierced with a sharp knife. Drain immediately and let cool slightly. (Scrape the skin from the cooked potatoes, if you want, as soon as they can be handled. For a decorative look with fingerlings, scrape off only a band of skin, about 1/2 inch thick, all around the long sides of the potato.)

Heat 2 tablespoons of the olive oil in a small saute pan. When hot, add the spring onions and the onion, toss to coat well, and cook for about a minute over medium-high heat. Add the garlic, toss to mix, and cook for just a few moments, then remove the pan from the heat.

Slice the potatoes while still warm, cutting them crosswise into 1/2-inch sections. Put the pieces in a large mixing bowl, pour the wine and 3 or 60ml of olive oil over them, and toss gently to distribute. Add the warm vegetables from the pan, mustard, chives, chopped herbs, salt, and pepper, and gently fold all together, mixing well but not crushing the potatoes. Taste the salad and add more seasonings as you like.

Serve the potatoes warm (no colder than room temperature). Arrange the large radicchio leaves, if you have them, in a close circle on the serving platter, with their curved insides up, to form a rough bowl. Spoon the potato salad inside the leaves, sprinkle chopped egg around the edges, and parsley over the top.
