How to prepare

1
Trim the root ends and dark green tops from the leeks, leaving the white and tender pale-green sections intact. Halve any thick leeks lengthwise, then rinse between the layers until no grit remains.
2
Set up a steamer over simmering water. Arrange the leeks in a single layer, cut side down where possible, cover, and steam for 15 to 18 minutes, until a knife slides through the thickest section with slight resistance.

3
While the leeks steam, toast the chopped walnuts in a dry skillet over medium heat for 3 to 4 minutes, stirring often, until fragrant and lightly browned. Transfer them to a plate to cool.
4
Whisk the olive oil, white wine vinegar, Dijon mustard, 1/2 teaspoon of the salt, and the black pepper in a small bowl until slightly thickened and emulsified.
5
Transfer the hot leeks to a serving platter and spoon the vinaigrette over them, turning gently to coat without breaking the layers. Rest for 5 minutes so the dressing can penetrate the vegetables.

6
Scatter the toasted walnuts and chives over the leeks. Taste and add the remaining salt if needed, then serve slightly warm or at room temperature.

Why this recipe works

Steaming preserves the leeks' delicate sweetness and keeps their layers tender without waterlogging them. The sharp mustard vinaigrette balances that sweetness, while walnuts and herbs add texture and freshness.

Storage and reheating

How to store it

Refrigerate covered for up to 3 days. Keep the walnuts separate and add them just before serving to preserve their crunch.

How to reheat it

Serve chilled, at room temperature, or gently warm the leeks for 1 to 2 minutes in a covered pan over low heat. Do not boil, or they may fall apart.
