Lentilles du Puy with Poached Egg and Dijon Dressing

Warm Lentilles du Puy with a poached egg sits somewhere between a French lentil salad and a simple vegetarian main. The small green lentils are prized for their peppery flavour and ability to stay distinct rather than turning soft, which makes them ideal for tossing with a sharp Dijon, red wine vinegar and olive oil dressing while still warm. Shallot and parsley add freshness, while the runny yolk turns the vinaigrette-coated lentils richer and more rounded on the plate. It is a practical lunch or light supper: savoury, tangy and satisfying without feeling heavy, with enough structure to serve on its own or alongside simply cooked greens.

Why this recipe works

  • Defined texture: Puy lentils hold their shape well, giving the salad a firm, satisfying bite rather than a soft or mushy finish.
  • Sharp dressing: Dijon mustard and red wine vinegar cut through the earthy lentils and the richness of the egg yolk.
  • Flexible serving: The lentils can be served warm as written, or prepared ahead and reheated gently before adding freshly poached eggs.

Ingredient notes

  • Choose lentils that hold their shape: Lentilles du Puy are ideal because they stay firm and slightly nutty after simmering. Other small green lentils can work, but softer varieties may give a looser salad.
  • Adjust the sharpness: Taste the dressing before serving and add a little more vinegar if the lentils need extra lift.
  • Dress while warm: Tossing the lentils with the vinaigrette while they are still warm helps them absorb the mustardy dressing more fully.

Timing notes

  • Serve the egg straight away: Poached eggs are best added just before serving so the whites stay tender and the yolk remains fluid.
  • Use the simmering time: Chop the shallot and parsley and whisk the dressing while the lentils cook to keep the recipe efficient.

Make-ahead tips

  • Make the lentils in advance: The dressed lentils can be refrigerated and reheated gently with a splash of water before serving.
  • Poach fresh eggs: For the best texture, store the lentils separately and poach the eggs only when you are ready to eat.

Common mistakes

  • Avoid a hard boil: A rolling boil can split the lentil skins and make the salad look broken; keep the water at a gentle simmer.
  • Do not overcook the lentils: Stop cooking once the lentils are tender but still intact, as they will soften slightly more when tossed with the dressing.

  1. Rinse the lentils, then tip them into a saucepan with the bay leaves, 0.5 tsp of the salt and the peppercorns. Cover with plenty of cold water and bring to the boil, then reduce to a gentle simmer. Cook for 20 to 25 minutes until the lentils are tender but still holding their shape.
  2. Meanwhile, finely chop the shallot and parsley. In a mixing bowl, whisk together the Dijon mustard, red wine vinegar, extra virgin olive oil and the remaining 1 tsp salt until emulsified. Taste and adjust with a little more vinegar if you want it sharper.
  3. When the lentils are ready, drain well and discard the bay leaves and peppercorns. While still warm, toss the lentils with the dressing, then fold through the shallot and most of the parsley. Keep warm while you poach the eggs.
  4. Fill a large pot with water and bring it to a gentle simmer. Crack in the eggs one at a time and poach for 3 to 4 minutes until the whites are set and the yolks are still soft. Lift out with a slotted spoon and let drain briefly.
  5. Divide the warm lentils between two plates and top each with a poached egg. Finish with the remaining parsley and a few extra grinds of pepper if you like. Serve straight away while the egg is still runny.

Recipe notes

Tips

  • For the best texture, keep the lentils at a gentle simmer rather than a rolling boil so the skins stay intact.
  • If serving to pregnant people, young children, older adults, or anyone immunocompromised, cook the eggs until the yolks are firm.

Substitutions

  • Replace red wine vinegar with white wine vinegar for a slightly lighter, cleaner acidity.
  • Replace fresh parsley with fresh dill for a more aromatic, aniseed-leaning finish.

Storage

  • Refrigerate up to 3 days
  • Store the dressed lentils in an airtight container in the fridge. Reheat gently in a saucepan with a small splash of water until hot, then poach fresh eggs to serve.
