Zesty Lemon, Arugula & Parmesan Pasta Salad

Some recipes politely wait to be photographed. This isn’t one of them. With peppery arugula, crunchy walnuts, tender pasta and a punchy lemon dressing all jostling for attention, this is the kind of salad that practically demands you grab a fork immediately. It’s zingy, fresh and wonderfully summery, with just enough crunch to keep every mouthful interesting. Best of all, it comes together suspiciously quickly for something that tastes this good.

The recipe

Method

  1. Cook the pasta - Bring a large pan of generously salted water to the boil and cook the pasta until tender, going just beyond al dente so it stays beautifully soft once chilled. Drain, then rinse under cold running water to stop the cooking process and remove any excess starch. Leave to drain thoroughly.
  2. Whisk up the lemon dressing - In a large bowl, combine the lemon juice and zest with the white balsamic vinegar, Dijon mustard, salt, black pepper, capers and finely chopped walnuts. Slowly pour in the extra virgin olive oil, whisking as you go, until you have a glossy, wonderfully fragrant dressing.
  3. Bring it all together - Tip the cooled pasta straight into the bowl and give everything a generous toss. Take your time here. You want every twist, bow or little pocket of pasta coated in that punchy, citrusy dressing.
  4. Add the greens - Scatter in the fresh rocket and finely sliced basil, if using, then gently toss again until everything is beautifully combined. The rocket should soften ever so slightly while still keeping its fresh, peppery character.
  5. Finish and serve - Add the freshly grated Parmesan or Pecorino and give the salad one final gentle toss. Finish with an extra crack of black pepper, a little lemon zest and, if you fancy it, another scattering of walnuts. Serve straight away or chill until you’re ready to dig in.

A few details make all the difference

01

Cook the pasta just right

Cook the pasta until tender rather than very firm al dente. Pasta firms up as it cools, so that extra minute helps keep the finished salad pleasantly tender. Rinse under cold water afterwards to stop the cooking, then drain really well so excess water doesn’t dilute the dressing.

02

Give the dressing plenty of zing

Use both the juice and zest of the lemon. The juice provides fresh acidity, while the zest brings a much more intense citrus fragrance. Whisk the olive oil in gradually to create a smooth, glossy dressing, then taste before adding the pasta and adjust the seasoning if necessary.

03

Save the rocket until last

Add the rocket and basil right at the end, once the pasta has cooled and been coated in dressing. This keeps the leaves fresh and vibrant rather than limp. Finish with freshly grated Parmesan or Pecorino, an extra scattering of walnuts and a little lemon zest for a salad that looks every bit as good as it tastes.

Why this recipe works

Fresh, bright and seriously zingy – Lemon juice, fragrant zest and peppery rocket give this pasta salad a beautifully fresh flavour that feels made for sunny days.
Big on texture – Tender pasta, crisp rocket and toasted walnuts create that addictive combination of soft, fresh and crunchy in every forkful. The dressing is the real star – Lemony, silky and just a little briny from the capers, it clings to the pasta and brings everything together without feeling heavy. Quick, simple and effortlessly impressive – There’s nothing complicated here, but the combination of Parmesan, lemon, walnuts and fresh greens makes it taste far more special than the effort involved. Perfect for making your own – Swap Parmesan for Pecorino, soften the rocket with a little baby spinach, add extra herbs or throw in whatever fresh greens you have waiting in the fridge. Made for summer tables – Serve it for a light lunch, bring it along to a picnic or pile it onto the table alongside your favourite barbecue dishes. It’s the sort of salad people keep going back to for “just one more spoonful”.

Cook’s notes

Cool the pasta properly

Give the cooked pasta a good rinse under cold running water. It stops the cooking immediately, removes excess starch and helps prevent the finished salad from becoming heavy or claggy. Let it drain really well before dressing.

Toast those walnuts

Don’t skip this tiny extra step. Toss the walnuts into a dry frying pan for a minute or two until fragrant. It wakes up their natural nuttiness and gives the salad an irresistible toasted crunch.

Freshly grate the cheese

Parmesan or Pecorino grated straight from the block is absolutely worth it. It has a fresher, richer flavour and a beautifully delicate texture that disappears into the dressing rather than sitting heavily on top.

Tame particularly peppery rocket

If your rocket has an especially fiery bite, mix in a handful of baby spinach. You’ll still get that distinctive pepperiness, but with a softer, more balanced finish.

Taste before you toss

The dressing should taste almost a little too punchy on its own because the pasta will mellow everything out. Taste it before adding the pasta and adjust with an extra squeeze of lemon, pinch of salt or crack of black pepper until it really sings.
