Ingredients You’ll Need

1/2 pound rotini pasta: This spiral shape is perfect for holding onto the creamy dressing. You can substitute with other pasta shapes like fusilli or penne.
1 cucumber, thinly sliced: Fresh and crisp, cucumbers add a refreshing crunch. If you’re feeling adventurous, try a seedless variety or even a Persian cucumber, both of which are great options.
1/2 sweet white onion, thinly sliced: Sweet onions provide just the right balance of flavor without overwhelming the dish. If sweet onions aren’t available, red onions can deliver a similar sweetness with a bit of sharpness.
1/2 cup sour cream: This is the base of our creamy dressing. You can use Greek yogurt for a healthier twist!
1/2 cup mayonnaise: Adds richness to the salad. If you’re concerned about calories, opt for light mayo.
1 tsp sugar: Just a pinch to balance the acidity of the vinegar. Honey can work as a natural substitute if you prefer.
1/2 tsp salt: Enhances the overall flavor. Adjust this according to your taste.
2 tbsp dill: Fresh or dried, dill lends a wonderful herbal note. If dill’s not your thing, try fresh parsley or basil.
2 tbsp white vinegar: Adds necessary tanginess to the dressing. Apple cider vinegar can be a flavorful alternative.

How to Make Creamy Cucumber Pasta Salad

Cook the Pasta: Prepare the 1/2 pound rotini pasta in a large pot of salted boiling water. Cook until al dente according to package directions, usually around 8-10 minutes. Once cooked, drain the pasta and rinse it under cold water to stop the cooking process and cool it down.
Prepare the Cucumbers: Take your cucumber and cut it in half lengthwise. Use a spoon to scoop out the seeds, which can make the salad watery. Then slice it thinly and set aside.
Soak the Onions: Next, slice the 1/2 sweet white onion thinly and place the slices in a bowl of cold water. This will help mellow their flavor, especially if they’re too strong for your taste.
Make the Dressing: In a small bowl, whisk together 1/2 cup sour cream, 1/2 cup mayonnaise, 1 tsp sugar, 1/2 tsp salt, 2 tbsp dill, and 2 tbsp white vinegar until smooth. Taste and adjust seasonings if necessary.
Combine Ingredients: In a large bowl, toss together the cooled pasta, sliced cucumber, drained onion, and dressing. Mix gently until everything is evenly coated.
Chill and Serve: Cover the bowl with plastic wrap and let it chill in the refrigerator for at least 45 minutes before serving. This allows all the flavors to meld wonderfully.

Storing & Reheating

To keep your Creamy Cucumber Pasta Salad fresh, store it in an airtight container in the refrigerator. It can be kept there for about 3-5 days. However, pasta salads like this one generally don’t do well at room temperature for extended periods, so don’t leave it out for more than two hours. If you need to store it longer, you can freeze it, but keep in mind that the texture may change. To refresh it after freezing, thaw in the fridge overnight and add a bit of fresh dressing before serving.

Chef’s Helpful Tips

Rinse the pasta well under cold water to stop cooking and prevent sticking.
If using fresh dill, chop finely to release its flavor fully.
Avoid soaking the onions for too long if you prefer a sharper taste; a quick soak is enough.
If you’re using gluten-free pasta, check the doneness carefully; gluten-free varieties often cook faster.
Consider adding cherry tomatoes or bell peppers for extra color and flavor.

Creamy Cucumber Pasta Salad not only captures the essence of summer but also brings a crowd together. With a zesty dressing and bursting with fresh flavors, this dish is a worthy addition to any gathering. Whether you’re enjoying it at a picnic, a family reunion, or just a quiet evening at home, I invite you to savor every bite of this scrumptious recipe.
