Made on Sunday, this covers three lunchboxes and a couple of adult lunches. It is one of the few cold lunches that does not get worse over a few days — as long as you handle the dressing correctly.

Dress it twice

Pasta keeps absorbing dressing as it sits, so a salad that was perfect on Sunday is dry by Tuesday. Dress it lightly when you make it, keep the rest of the dressing in a jar, and add a spoonful to each portion as you pack it.

For a lunchbox specifically, the better move is to send the dressing in its own small pot — the same wet-away-from-dry principle from our school lunch guide. It also means one child can have it plain, which is often the difference between eaten and not.

Rinse the pasta, just this once

Normally rinsing pasta is a mistake because it washes off the starch that holds sauce. For a cold salad it is the right call: it stops the cooking immediately and prevents the pieces welding into a block. Rinse under cold water until properly cool, then drain very well.

Cook it a minute past al dente, too. Pasta firms up in the fridge, and properly al dente pasta eaten cold is unpleasantly hard.

Cutting for younger children

Cherry tomatoes and grapes are a choking hazard for children under about four and should be quartered lengthways, not halved crossways. Mozzarella pearls should be quartered as well. NHS and American Academy of Pediatrics choking guidance is the thing to follow here.

Keeping it cold

This contains cooked pasta and dairy, so it needs to stay chilled — two slim ice packs and an insulated bag, as set out in keeping a packed lunch cold. It keeps three to four days refrigerated.

A cold pasta salad built to keep for several days of lunchboxes.

Prep15 minutes
Cook10 minutes
Total25 minutes
ServesServes 4-6

Ingredients

  • 300g short pasta - fusilli, farfalle or penne
  • 200g cherry tomatoes, quartered lengthways
  • 1/2 cucumber, diced
  • 150g mozzarella pearls or cubed cheddar
  • 150g tinned sweetcorn, drained
  • A handful of basil leaves, torn (optional)
  • 4 tbsp olive oil
  • 1 tbsp red wine vinegar or lemon juice
  • 1/2 tsp salt, plus pepper

Instructions

  1. Cook the pasta in well-salted boiling water for 1 minute longer than the packet says - cold pasta firms up and al dente is too hard eaten cold.
  2. Drain, then rinse under cold running water until completely cool. Drain very thoroughly.
  3. Whisk the olive oil, vinegar, salt and pepper together in a jar.
  4. Quarter the cherry tomatoes lengthways, dice the cucumber, and quarter the mozzarella pearls if serving young children.
  5. Combine the pasta, tomatoes, cucumber, cheese and sweetcorn in a large bowl.
  6. Add about half the dressing and toss gently. Keep the rest in the jar.
  7. Refrigerate. When packing each portion, add a spoonful more dressing, or send it in a separate small pot.

Notes

  • Quarter cherry tomatoes and grapes lengthways for children under about four.
  • Keep most of the dressing back - pasta absorbs it over a few days and dries out.
  • Keeps 3 to 4 days refrigerated. Pack with two slim ice packs in an insulated bag.
  • Swap in whatever is in the fridge: peppers, olives, ham, tuna, peas.
