Salade de Lentilles du Puy (French Lentil Salad with Mustard Dressing)

Salade de Lentilles du Puy is the kind of French salad that depends on restraint and good texture: small, slate-green Puy lentils cooked until tender but still intact, then dressed while warm so they absorb a sharp Dijon vinaigrette. Served at room temperature, it is savoury, tangy and quietly substantial, with shallot for bite and parsley for freshness. It works well as a light lunch, a make-ahead side, or part of a simple spread with bread, vegetables or grilled foods, and keeps its character because the lentils hold their shape rather than collapsing into a mash.

Why this recipe works

  • Warm dressing method: Tossing the lentils while still warm helps them absorb the mustard vinaigrette more fully.
  • Sharp but balanced: Dijon mustard and red wine vinegar bring brightness, while olive oil rounds out the dressing.
  • Good for make-ahead meals: The salad holds well in the fridge and can be brought back to room temperature before serving.

Ingredient notes

  • Use Puy lentils if possible: Puy lentils hold their shape well after simmering, giving the salad a firm, distinct texture rather than a soft mash.
  • Adjust the vinaigrette to taste: If the salad tastes flat after resting, add a little more vinegar or mustard to sharpen the dressing.
  • Fresh herbs matter: Fresh parsley gives the finished salad a cleaner, brighter flavour than dried herbs.

Timing notes

  • Let the lentils absorb the dressing: The short rest after tossing allows the warm lentils to take on the mustard vinaigrette more evenly.
  • Serve at room temperature: The flavour is clearest once the salad is no longer hot from the pan or cold from the fridge.

Common mistakes

  • Avoid mushy lentils: Start checking early and drain the lentils as soon as they are tender but still holding their shape.
  • Do not let them cool completely: Cold lentils absorb the dressing less readily, so combine them with the vinaigrette while still warm.

Make-ahead tips

  • Make it ahead: The salad keeps well in an airtight container in the fridge for up to 3 days.
  • Bring back to room temperature: Let the salad sit out briefly before serving so the olive oil loosens and the flavours open up.

  1. Rinse the lentils in a colander, then tip into a saucepan and cover with plenty of cold water. Bring to the boil, then reduce to a steady simmer and cook for 18–22 minutes until tender but still holding their shape. Add 1 tsp of the fine sea salt for the final 2 minutes of cooking.
  2. Meanwhile, finely chop the shallot and parsley. In a mixing bowl, whisk together the dijon mustard, red wine vinegar, extra virgin olive oil, black pepper and the remaining 0.5 tsp fine sea salt until emulsified.
  3. Drain the lentils well, then add them to the bowl while still warm. Toss with the shallot and parsley until everything is evenly coated, then leave for 5 minutes so the lentils absorb the dressing. Serve at room temperature.

Recipe notes

Tips

  • Do not overcook the lentils: start checking at 18 minutes and drain as soon as they are tender, otherwise the salad turns mushy.
  • Tossing the lentils while warm helps them take on the dressing; if they cool too much, briefly warm them in the saucepan over low heat before dressing.

Substitutions

  • Replace red wine vinegar with white wine vinegar for a slightly lighter, cleaner acidity.
  • Replace dijon mustard with whole-grain mustard for a coarser texture and milder heat.

Storage

  • Refrigerate up to 3 days
  • Cool completely, then refrigerate in an airtight container for up to 3 days. Bring back to room temperature before serving, or warm gently in a saucepan over low heat just until loosened.
