Ingredients You’ll Need
- 1/2 pound rotini pasta: This spiral shape holds onto the creamy dressing beautifully. You can substitute with penne or bowtie pasta if desired.
- 1 cucumber, thinly sliced: Fresh cucumbers add a crunchy texture. If it’s too watery, consider using English cucumbers for fewer seeds.
- 1/2 sweet white onion, thinly sliced: Adds a mild sweetness. If you prefer a stronger bite, feel free to switch to red onion or scallions.
- 1/2 cup sour cream: This lends creaminess to the dressing. Greek yogurt can be a healthier alternative if you’re looking to lighten it up.
- 1/2 cup mayonnaise: Adds richness. Look for a light version for a lower-calorie option.
- 1 tsp sugar: This helps balance the acidity of the vinegar. You can use honey or a sugar substitute if needed.
- 1/2 tsp salt: Enhances overall flavor; adjust to your taste preference.
- 2 tbsp dill: Fresh dill is ideal for its bright flavor. Dried dill can work too, but use less (about 1 tablespoon).
- 2 tbsp white vinegar: Gives the salad a nice tang. You can substitute with apple cider vinegar for a different flavor profile.
How to Make Creamy Cucumber Pasta Salad
- Cook the Pasta: Start by cooking 1/2 pound of rotini pasta in a large pot according to package directions until al dente. Rinse under cold water until the pasta cools and set it aside.
- Prepare the Cucumber: Take your cucumber, cut it in half lengthwise, and scoop out the seeds with a spoon. This step prevents the salad from getting too watery. Cut the cucumber into thin slices and set aside.
- Soak the Onion: To mellow out the flavor, take 1/2 sweet white onion, thinly slice it, and soak those slices in a bowl of cold water for about 10 minutes. Then, drain the onion and add to your bowl.
- Make the Dressing: In a separate small bowl, whisk together 1/2 cup of sour cream, 1/2 cup mayonnaise, 1 tsp sugar, 1/2 tsp salt, 2 tbsp dill, and 2 tbsp white vinegar until smooth.
- Combine Everything: In a large bowl, toss the cooled pasta, sliced cucumber, soaked onion, and dressing until well combined.
- Chill: Cover your bowl and let it sit in the refrigerator for at least 45 minutes before serving. This waiting time allows the flavors to meld beautifully.
Storing & Reheating
Store your Creamy Cucumber Pasta Salad in an airtight container in the fridge for up to 3 days. It’s best enjoyed cold, so there’s no need for reheating. If you decide to freeze it, keep in mind that the texture may change slightly after thawing, and it’s best to consume it within three months. To refresh the flavor after storage, simply give it a gentle toss with a splash of vinegar or a few extra herbs.
Chef’s Helpful Tips
- To avoid overly mushy pasta, make sure to rinse it under cold water right after cooking to stop the cooking process.
- If possible, consider using freshly chopped dill for an extra burst of flavor.
- Prepare the salad a few hours in advance to give the cucumbers and onion time to absorb the dressing.
- If you find the salad is too thick after sitting, simply stir in a bit of cold water or additional vinegar to reach your desired consistency.
Creamy Cucumber Pasta Salad is not just delicious; it’s also wonderfully versatile! It’s a great side for grilled meats, or you can enjoy it as a light lunch on its own. Feel free to switch up the ingredients—adding cherry tomatoes or bell peppers can give it even more color and flavor.
