French Green Lentils with Lemon-Thyme Mustard, Capers & Herbs

At the Lello table

French green lentils need very little when they are dressed at the correct moment. Here, the warm lentils take on a sharp lemon-thyme mustard vinaigrette; capers provide saline punctuation; and parsley, chives and peppery olive oil keep the finish fresh rather than heavy.

Method

1. Combine the lentils, water, bay leaf, garlic, carrot and a generous pinch of salt in a medium saucepan. Bring to a gentle boil, reduce to a steady simmer and cook for approximately 20 to 25 minutes, until the lentils are tender throughout but still hold their shape.
2. While the lentils cook, place the minced shallot and red wine vinegar in a large bowl and leave for 5 minutes. This softens the raw edge of the shallot without removing its character.
3. Whisk the lemon-thyme mustard into the shallot mixture. Slowly whisk in 3 tablespoons / 45 mL of the olive oil until lightly emulsified. Stir in the chopped capers and several turns of black pepper.
4. Drain the lentils thoroughly and discard the bay leaf and garlic. Leave the carrot with the lentils. Transfer the still-warm lentils directly into the vinaigrette and fold gently until evenly coated.
5. Rest for 10 minutes. Taste only after this rest; the lentils will continue to take up vinegar, mustard and salt as they cool.
6. Fold in the parsley and chives. Adjust with a little more vinegar, salt or pepper if necessary, then finish with the remaining 1 tablespoon / 15 mL Heritage olive oil.
7. Serve warm or at room temperature. Avoid serving refrigerator-cold; the olive oil, herbs and mustard become more expressive as the lentils lose their chill.

Cook’s notes

• Dress the lentils warm, but add the delicate herbs later. Warm lentils absorb seasoning far more effectively than cold ones, while parsley and chives retain their color and definition when added after the first rest.
• There is intentionally no additional lemon juice in the base recipe. The lemon zest and thyme already present in the mustard should remain recognizable rather than being buried beneath extra citrus.
• The final spoonful of Heritage olive oil is deliberate: it preserves the oil’s fresh, peppery character instead of allowing all of it to disappear into the dressing.

Substitutions

• Black beluga lentils are the best alternative because they also remain intact after cooking. Ordinary brown lentils work, but produce a softer and less composed salad.
• A good Dijon can replace the lemon-thyme mustard; add ½ teaspoon finely grated lemon zest and a small pinch of fresh thyme leaves.
• Finely chopped cornichons can replace the capers, although the result becomes more pickle-forward and less saline.
• Tarragon or chervil can replace the chives in small quantities. Avoid adding several assertive herbs at once.
• Sherry vinegar is excellent in place of red wine vinegar. White wine vinegar works but gives a sharper, less rounded result.

To serve

Serve beside roast chicken, pork, grilled sausages or a simple omelet. For a vegetarian lunch, spoon the lentils onto a shallow platter and add a softly cooked egg or a piece of warm goat cheese.

Storage & make-ahead

The lentils keep well for up to 3 days refrigerated. Bring them toward room temperature before serving and refresh with a teaspoon of vinegar, a little fresh parsley and a final thread of olive oil.
