Macaroni Salad with Sweetcorn

Cold macaroni salad is an American-style pasta salad made for serving chilled, with tender short pasta folded through a creamy, lightly sharp dressing. In this version, sweetcorn brings sweetness and bite, while celery and red onion add the crisp texture that keeps the salad from feeling heavy. Dijon mustard and apple cider vinegar cut through the mayonnaise, giving a clean tangy finish rather than a flat richness. It suits packed lunches, picnics and simple make-ahead meals, and benefits from a short rest in the fridge so the pasta, vegetables and dressing settle into a cohesive salad.

Why this recipe works

  • Good crunch and bite: Tender macaroni is balanced by crisp celery, red onion and sweetcorn, so the salad does not feel flat or overly soft.
  • Creamy but tangy: Dijon mustard and apple cider vinegar cut through the mayonnaise, keeping the dressing fresh and well balanced.
  • Improves after chilling: A short rest in the fridge lets the dressing coat the pasta properly and brings the flavours together before serving.

Timing notes

  • Chill before serving: Allow time for the salad to chill after mixing; it tastes cleaner and holds its texture better when served cold.
  • Best served cold: Keep the salad refrigerated until needed, especially because the dressing is mayonnaise-based.

Ingredient notes

  • Fresh corn adds sweetness: Corn cut from the cob gives the salad a sweeter, juicier texture than softer canned kernels.
  • Adjust the sharpness: Taste the dressing before adding the pasta and increase the vinegar slightly if you prefer a brighter finish.
  • Soften the onion bite: Soaking diced red onion briefly in cold water makes it milder while keeping its crisp texture.

Make-ahead tips

  • Make ahead on the day: The salad can be mixed in advance and kept covered in the fridge until ready to serve.
  • Serve without reheating: This salad is designed to be served cold; stir it well before serving to redistribute the dressing.
  • Good for packed lunches: Store in a chilled container and eat within the stated fridge time for the best texture and food safety.

  1. Bring a large pot of water to the boil. Cook the macaroni until just tender, then drain well in a colander and rinse briefly under cold water to cool it down. Leave to drain thoroughly so the dressing does not become watery.
  2. In the same pot, boil the corn on the cob until tender. Drain, cool until you can handle it, then cut the kernels off the cob. Set aside.
  3. Finely dice the celery and red onion. In a mixing bowl, whisk together the mayonnaise, Dijon mustard, apple cider vinegar, caster sugar and black pepper until smooth. Taste and adjust with a little more vinegar if you want it sharper.
  4. Add the cooled macaroni, sweetcorn, celery and red onion to the bowl. Toss until everything is evenly coated and the salad looks creamy. Cover and chill so the flavours come together.

Recipe notes

Tips

  • Drain the macaroni very well and let it sit for a minute or two in the colander; excess water will thin the mayonnaise dressing.
  • For a milder onion flavour, soak the diced red onion in cold water for 5 minutes, then drain well before mixing in.
  • If serving to anyone vulnerable, use pasteurised mayonnaise.

Substitutions

  • Replace apple cider vinegar with white wine vinegar for a slightly softer acidity.
  • Replace caster sugar with honey for a rounder sweetness.

Storage

  • Refrigerate up to 2 days
  • Keep covered in the fridge and stir before serving. If it thickens after chilling, loosen with a small spoonful of apple cider vinegar and mix well.
