This cool and creamy cucumber pasta salad is a favorite for summer cookouts and easy lunches. Every bite brings together tender pasta, crisp cucumbers, and a tangy, herby dressing that is both refreshing and satisfying. It is incredibly simple to toss together, travels well, and never fails to disappear quickly at gatherings.
When I first made this salad for a family picnic, I underestimated just how quickly it would vanish. Everyone went back for seconds and asked for the recipe. Now I bring it to every summer potluck and there is never a spoonful left.
Ingredients
- English cucumber: Uses fewer seeds and a thin skin for easy prep Look for firm and unblemished cucumbers
- Medium pasta like penne or rotini: These shapes hold dressing well and are easy for scooping Use your favorite
- Sweet white onion: Adds crunch and a mild bite Choose one that feels heavy and is free from soft spots
- Sour cream: Provides cool tang and creaminess Go for full fat if possible for best texture
- Mayonnaise: Gives that classic creamy base Use real mayo for best results
- Sugar: Balances acidity in the dressing Even a small amount makes a difference
- Salt: Important for seasoning the pasta and balancing flavors Use a flaky or kosher salt
- Fresh dill: Brings a burst of herby aroma and freshness Only use fronds and avoid woody stems
- Vinegar: Gives bright tang Apple cider or white wine vinegar are both good picks
- Black pepper: Adds just the right kick Freshly cracked is best
Step-by-Step Instructions
- Make the Dressing:
- Whisk together sour cream mayonnaise vinegar sugar salt dill and a few grinds of pepper in a small bowl until totally smooth. Allow it to sit for ten minutes to marry all those flavors.
- Soak the Onions:
- Thinly slice the onion and submerge in a bowl of very cold water for about ten minutes to take away the harsh sharpness. Drain well before adding to the salad.
- Cook and Cool the Pasta:
- Bring a large pot of salted water to a boil then add the pasta cooking until just al dente. Immediately drain and rinse with cold water to stop the cooking and cool it completely. Drain very well so the salad does not get watery.
- Slice the Cucumber:
- Cut the cucumber in half lengthwise then gently scoop out the seeds with a spoon. Slice into thin half moons for the ideal bite and crunch in every forkful.
- Combine and Chill:
- In a large mixing bowl join cooked pasta drained onions and sliced cucumber. Pour on all of the creamy dressing and toss especially well to coat every piece. Chill for at least one hour so the flavors blend and the salad is cold and ready.

One of my favorite parts of this salad is the fresh dill. It lifts the whole dish and brings a herby brightness you will not get from dried herbs. My grandmother always grew dill in her garden just for recipes like this and every time I use it I think of spending summers at her house.
Storage Tips
Chill your pasta salad for at least an hour before serving to let flavors develop. Store any leftovers in an airtight container in the fridge for up to three days. If cucumbers release a bit of water just give everything a good toss before serving and it will taste fresh again. Making ahead is easy just keep the pasta separate from the veggies and dressing until an hour before you serve for the crispiest texture.
Ingredient Substitutions
If you cannot find English cucumber use regular cucumber but peel and seed it first. Greek yogurt can work for part of the sour cream for a lighter flavor. Fresh chives or parsley are a good stand in for dill if needed but the herby punch of dill is classic. Use any sturdy pasta shape such as fusilli bowtie or even small shells for fun variety.
