ABOUT THIS RECIPEFresh fennel, warm lentils
This salad brings together two very different textures: soft, substantial lentils and paper-thin raw fennel. The lentils are tossed with the vinaigrette while still warm, so they absorb the dressing before the fennel is added. That order is helpful: the fennel stays crisp and fresh, while the lentils don’t taste dry or bland. Orange adds fruity acidity; Dijon mustard and red wine vinegar keep everything tangy and savoury.
Green lentils work well because they hold their shape reasonably well when gently cooked. Rinse them first and let them simmer gently rather than boiling vigorously. Start checking after about eighteen minutes: here, cooked means soft enough to eat but still with a slight bite. The exact time varies depending on the type and how long the lentils have been in the packet. Drain them as soon as they’re ready; cooking them for too long will make the salad mushy. Don’t let them cool completely before adding the dressing.
Fennel is generally available in the Netherlands all year round, with supplies from different growing regions. Choose a firm bulb without limp or brown patches. A mandoline gives you thin, even slices, but a sharp chef’s knife works too: slice as thinly as you can and keep your fingers out of the blade’s path. If the fennel fronds are fresh and bright, you can finely chop them and use them as an herb; otherwise, flat-leaf parsley adds a fresh green note. The orange segments make the dish juicier, so remove as much of the bitter white pith as possible too.
Taste the vinaigrette before adding it to the lentils. Oranges vary in sweetness, and the mustard also affects how sharp the dressing tastes. If it’s very acidic, add a little extra olive oil; for more tang, add a little red wine vinegar. Toast the hazelnuts in a dry pan until fragrant and lightly coloured. Let them cool before roughly chopping them, so they stay crunchy and don’t make the fennel wilt while still warm.
Serve the salad for lunch or as a side with roast chicken, pan-fried white fish or a simple omelette. For a main-course salad, you can increase the amount of lentils, but keep plenty of fennel and vinaigrette so every bite stays fresh. You can store leftovers covered in the fridge and eat them within two days. The fennel becomes less crisp over time, so add the hazelnuts only to the portions you’re serving. Eat the salad cold or let it come to room temperature briefly; there’s no need to reheat it.
