This healthy cucumber pasta salad brings together tender noodles, crisp cucumber, and a creamy dill dressing for a dish that is refreshing and satisfying any time of year. It is my go to side for potlucks and an easy lunch option for any busy week. Combining simple pantry staples with fresh produce, it delivers tons of flavor without fuss.
My family started asking for this salad on every picnic after I first brought it to a backyard barbecue. It is one of those dishes that disappears fast and always gets recipe requests.
Ingredients
- English cucumber: Brings crispness and hydration to balance the creamy dressing. Choose firm unblemished cucumbers for best results
- Medium pasta (penne or rotini): Captures dressing in every bite. Go for quality dried pasta for better texture
- Sweet white onion: Adds a punch of flavor without being overpowering. Pick onions with shiny skins that feel heavy for their size
- Sour cream: Gives richness and a tangy finish. Go for full fat for best texture but low fat works too
- Mayonnaise: Creates a silky base for the dressing. Quality mayo makes a difference and homemade is always a treat
- Sugar: Provides just a touch of sweetness to balance acidity
- Salt: Enhances all the flavors
- Fresh dill: Offers bright herby notes. Do not skip it and always use fresh not dried if you can
- Vinegar: Sharpens and brightens the final dish. White wine vinegar is best but apple cider works as a substitute
- Black pepper: Brings gentle spice and rounds out the flavors. Freshly ground is preferred
Step-by-Step Instructions
- Prepare the Dressing:
- Thoroughly whisk together the sour cream mayonnaise vinegar sugar salt fresh dill and black pepper in a small bowl until the mixture is completely smooth and the herbs are evenly distributed The longer this sits the deeper the flavor so set aside while you prep other ingredients
- Prepare the Onions:
- Using a sharp knife slice the sweet white onion paper thin so it almost disappears in the salad Submerge these slices in a bowl of ice cold water for at least ten minutes to tame any bitterness and create a cleaner milder onion flavor
- Cook and Cool the Pasta:
- Bring a large pot of salted water to a rolling boil and cook your chosen pasta until just al dente so it holds up to tossing Immediately drain and rinse thoroughly under cold water to stop the cooking process and remove excess starch This step is important for maximizing the salad’s freshness
- Slice the Cucumber:
- With a sturdy chef’s knife cut the cucumber in half lengthwise and scoop out the seeds using a small spoon This keeps the salad from getting watery Slice each half into thin crescents for even distribution and superior crunch in every mouthful
- Assemble the Salad:
- Toss your cooled pasta drained onions and cucumber slices in a large mixing bowl Pour the creamy dill dressing over everything and use a spatula to gently fold ingredients until well coated Let the salad chill covered in the fridge for at least forty minutes to allow the flavors to marry Serve cold and enjoy

Fresh dill is my favorite touch and truly makes the salad sing It reminds me of cooking in my grandmother’s kitchen where we picked dill fresh from her garden Adding too little dill just does not have the same effect so measure generously if you love big herb flavor
Storage Tips
Store any leftovers in an airtight container in the refrigerator The salad holds up well for up to three days but the texture is best within twenty four hours If it looks a bit dry after sitting just stir in a spoonful of sour cream or mayonnaise to refresh before serving
Ingredient Substitutions
You can use Greek yogurt instead of sour cream for extra protein or swap in a plant based mayo for a vegan option If you forget to buy dill chives or flat leaf parsley work as fresh herb alternatives
Serving Suggestions
This salad pairs perfectly with grilled chicken kabobs smoked salmon or even as a hearty vegetarian main with a handful of feta on top For a picnic lunch it travels well and fits into any summer spread with ease
