Watercress Salad with Mustard Vinaigrette

This vibrant watercress salad with mustard vinaigrette is a masterclass in balancing bold, punchy flavours with simple techniques. The peppery crunch of fresh watercress provides a robust base for the silky dressing, which uses high-quality red wine vinegar and spicy Dijon mustard to create a sharp, sophisticated finish. It is an ideal choice for those seeking a light yet flavourful addition to a weekend lunch or a formal dinner party.

As a naturally vegan dish, this salad is as healthy as it is delicious, offering a nutrient-dense alternative to heavier side dishes. The secret lies in the emulsion; by slowly whisking the olive oil into the mustard base, you create a glossy coating that clings perfectly to the leaves. Serve it alongside roasted vegetables or a crusty sourdough loaf to soak up the remaining vinaigrette.

Ingredients for Watercress Salad with Mustard Vinaigrette

  • 2 tablespoons Dijon mustard

  • 1 tablespoon best-quality red wine vinegar

  • 1/2 small garlic clove, finely grated

  • Kosher salt, freshly ground pepper

  • 1/4 cup olive oil

  • 2 small bunches watercress, tough stems trimmed (about 2400ml )

Whisk mustard, vinegar, and garlic in a medium bowl; season with salt and pepper, then gradually stream in oil, whisking constantly. Whisk until dressing is emulsified and thick.

Add watercress to dressing, season with more salt and pepper, and gently toss until watercress is evenly coated (you want to be careful not to bruise or wilt greens when tossing, so use a light hand). Pile salad lightly onto plates.
