Ingredients
- 225 grams penne pasta (8 ounces)
- 1/2 medium white onion, finely minced (approximately 100 grams)
- 1 large English cucumber, ends trimmed and sliced (approximately 400 grams)
- Freshly ground black pepper, to taste
- 120 ml full-fat mayonnaise (1/2 cup), such as Hellmann's
- 5 grams granulated sugar (1 teaspoon)
- 120 ml full-fat sour cream (1/2 cup)
- 30 ml white wine vinegar (2 tablespoons)
- 30 ml fresh dill, finely chopped (2 tablespoons)
- 2.5 grams fine sea salt (1/2 teaspoon)
Instructions
- Prepare the Dressing. In a small bowl, combine the mayonnaise, sour cream, white wine vinegar, granulated sugar, fine sea salt, freshly ground black pepper, and finely chopped fresh dill. Whisk vigorously until all ingredients are thoroughly blended and the dressing is smooth and creamy. Set this aside to allow the flavors to deepen and meld, enhancing the overall taste of the salad.
- Mellow the Onions. Take the finely minced 1/2 white onion and place it in a bowl. Cover the onion completely with cold water and let it soak for at least 15-20 minutes. This crucial step significantly reduces the raw onion's pungency and sharpness, leaving behind a milder, sweeter flavor that integrates beautifully into the salad without overpowering other ingredients. Drain thoroughly before use.
- Cook and Cool the Pasta. Bring a large pot of salted water to a rolling boil. Add the penne pasta and cook according to package directions until it reaches an al dente texture, typically 10-12 minutes. Al dente pasta will be firm to the bite but not hard. Immediately drain the pasta and rinse it under cold running water until completely cool. This stops the cooking process and prevents the pasta from becoming mushy, ensuring a pleasant texture in the cold salad. Drain very well.
- Prepare the Cucumber. Wash and trim the ends of the English cucumber. Slice the cucumber in half lengthwise. Using a spoon, carefully scoop out and discard the seeds from each half; this helps prevent the salad from becoming watery. Then, slice the cucumber halves into thin, crescent-shaped pieces, approximately 3-4 mm thick, to provide a refreshing crunch.
- Assemble the Salad. In a large mixing bowl, gently combine the cooled and drained penne pasta, the thoroughly drained and mellowed white onion, and the thinly sliced cucumber. Pour the prepared dill dressing over the ingredients. Using a large spoon or spatula, toss everything together carefully until all the pasta and vegetables are evenly coated with the creamy dressing. For the best flavor development, allow the assembled salad to chill in the refrigerator for at least 40 minutes before serving. This resting period allows the pasta to absorb the dressing's flavors, creating a more cohesive and delicious dish.

Essential Success Tips
- Ensure your pasta is truly al dente; overcooked pasta will become mushy in a cold salad.
- Don't skip rinsing the pasta with cold water; it's essential for a good texture in cold salads.
- Soaking the white onion is a game-changer; it removes harshness and leaves a sweet, subtle flavor.
- Adjust the amount of dill and black pepper in the dressing to suit your taste preference.
- Allow ample chilling time for the flavors to fully meld; this significantly improves the salad's taste.
Professional Cooking Secrets
- For an extra layer of flavor and crunch, lightly toast a handful of sunflower seeds or slivered almonds and sprinkle them over the salad just before serving.
- To make a truly vibrant dill dressing, use fresh dill and consider adding a tiny pinch of dried mustard powder or a dash of celery seed for an unexpected depth.
- If preparing this salad for a large gathering, make the dressing a day ahead and store it separately. Toss with the pasta and vegetables closer to serving time to maintain optimal freshness and texture.

Notes
- Storage: Store any leftover Healthy Cucumber Pasta Salad in an airtight container in the refrigerator for up to 3 days. The flavors will continue to develop, but the pasta may absorb more dressing, so you might want to add a splash of milk or extra sour cream if it becomes too dry.
- Variation: For a touch of heat, finely dice a jalapeño (seeds removed) and add it to the dressing. For a protein boost, stir in cooked, shredded chicken breast or chickpeas.

Absolutely! This Healthy Cucumber Pasta Salad is excellent for making ahead. Prepare it up to 24 hours in advance, allowing the flavors to meld even more beautifully. Just ensure it's stored in an airtight container in the refrigerator.
What kind of vinegar should I use?
While the recipe suggests white wine vinegar for its bright, clean flavor, apple cider vinegar or even distilled white vinegar can be used as alternatives. White wine vinegar offers a more nuanced tang that complements the dill perfectly.
