The Best Pasta Salad Recipe — Cold, Creamy, and Packed With Flavor

It started as an accident, the way the best recipes often do. A neighborhood block party, a potluck table already crowded with store-bought sides, and a big ceramic bowl my mother carried in like she owned the place. She set it down without ceremony, gave the serving spoon a quick wipe, and walked away to find a lawn chair. By the time the burgers came off the grill, the bowl was empty. Three different neighbors stopped her before the afternoon was over to ask what was in it. She smiled and said, “Nothing fancy — just what I had.” That pasta salad became the thing people requested every single summer after that. Birthdays, Fourth of July, end-of-school cookouts — someone always called ahead to make sure she was bringing it.

This recipe is built on that same spirit. Fresh ingredients, a bold homemade dressing, and enough texture in every bite to keep you going back for more. If you’ve been looking for the best pasta salad recipe to bring to your next gathering, this is the one that empties the bowl every time.

Ingredients

For the Pasta Salad

  • 12 oz (340 g) rotini pasta
  • 1 cup cherry tomatoes, halved
  • 1 medium cucumber, quartered and sliced
  • ½ cup black olives, sliced
  • ½ cup diced ham or salami (about 3 oz)
  • ¼ cup red onion, finely diced
  • ¼ cup fresh basil leaves, roughly torn
  • ½ cup shredded Parmesan cheese

For the Italian Dressing

  • ⅓ cup (80 ml) extra virgin olive oil
  • 3 tablespoons red wine vinegar
  • 1 tablespoon fresh lemon juice
  • 1 teaspoon Dijon mustard
  • 1 teaspoon honey
  • 1 teaspoon dried oregano
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ½ teaspoon fine sea salt
  • ¼ teaspoon black pepper
  • ¼ teaspoon red pepper flakes (optional)

Instructions

Step 1 — Cook the pasta Bring a large pot of generously salted water to a boil. Cook the rotini according to package directions until just al dente — firm with a slight bite. Do not overcook. Pasta that’s too soft turns mushy once it absorbs the dressing. Drain immediately and rinse under cold running water until completely cool. Shake off as much water as possible and spread on a clean kitchen towel for a few minutes to dry.

Step 2 — Make the dressing In a small bowl or jar, combine the olive oil, red wine vinegar, lemon juice, Dijon mustard, honey, oregano, garlic powder, onion powder, salt, pepper, and red pepper flakes if using. Whisk vigorously until fully emulsified, or seal the jar and shake for 30 seconds. Taste and adjust — more vinegar for tang, more honey for balance, more salt if it tastes flat.

Step 3 — Combine everything In a large bowl, combine the cooled pasta, cherry tomatoes, cucumber, olives, ham or salami, and red onion. Pour about three-quarters of the dressing over the top and toss well to coat every piece. Add the fresh basil and Parmesan and toss gently one more time.

Step 4 — Chill and finish Cover the bowl and refrigerate for at least one hour before serving — two hours is even better. The pasta will absorb the dressing as it chills and the flavors will deepen and come together beautifully. Just before serving, taste again and add the remaining dressing if needed. Finish with a little extra fresh basil and a dusting of Parmesan on top.

Pro Tips

  • Salt your pasta water generously — it should taste like mild seawater. This is the only opportunity to season the pasta itself, and under-salted pasta makes the whole salad taste flat no matter how good the dressing is.
  • Always dress pasta salad twice — once right after mixing and once just before serving. Pasta absorbs dressing as it sits in the fridge, so the salad can taste dry after chilling. That second addition brings it back to life.
  • Dry your pasta well before tossing. Excess water on the surface dilutes the dressing and makes the salad watery. A few minutes on a towel makes a real difference.
  • Add the fresh basil just before serving, not ahead of time. Basil bruises and darkens when it sits too long in an acidic dressing.
  • For a creamier version, whisk 2 tablespoons of mayonnaise into the dressing. It adds richness without making the salad heavy.

Storage and Make-Ahead

Pasta salad is one of the best make-ahead dishes in any cook’s repertoire. Prepare it fully up to 24 hours in advance and keep it refrigerated, tightly covered. Hold back a little dressing and the fresh basil to add just before serving. Leftovers keep well in the refrigerator for up to 4 days. This recipe does not freeze well — the vegetables lose their texture and the pasta turns soft.

FAQ

Can I make pasta salad the night before? Absolutely — it actually tastes better after an overnight rest in the fridge. Just save a splash of dressing and the fresh basil to add right before serving to keep everything bright and fresh.

What pasta shape works best for pasta salad? Rotini is ideal because the spirals trap the dressing and hold onto the small mix-ins. Penne, farfalle, and fusilli also work well. Avoid long pasta like spaghetti — it doesn’t mix evenly and is awkward to serve.

Can I make this pasta salad vegetarian? Easily. Simply leave out the ham or salami and add extra vegetables — roasted red peppers, artichoke hearts, or sun-dried tomatoes are all excellent substitutes that add plenty of savory depth.

Why does my pasta salad taste bland after chilling? Pasta absorbs salt and acid as it sits. Always taste again just before serving and adjust with a pinch of salt, a splash of vinegar, or a drizzle of fresh olive oil. This one step transforms a flat salad into a great one.

How long does pasta salad last in the fridge? Up to 4 days in an airtight container. The vegetables will soften slightly over time, but the flavor actually improves on day two. Give it a good toss and a taste before serving leftovers.
