The recipe combines two of my favorite summer side dishes.  Creamy Cucumber Salad meets pasta salad in this amazing side for a perfectly refreshing new summer staple!  I love a good pasta salad, not only are they easy to make but they can usually be prepared well ahead of time making them the perfect potluck dish!

Fresh crisp cucumbers in a simple and creamy sauce loaded with dill from the garden is tossed with your favorite pasta.  The dressing in this salad doesn’t have a lot of ingredients, but that’s really the beauty of this recipe!

If you have access to fresh dill, it really makes a huge difference in this salad.  For a great twist you can also add in a  handful of chopped tomatoes or halved cherry tomatoes or a squeeze of lemon juice.

While it’s not required, soaking the onions in cold water for a few minutes takes just a little bit of bite out of them.  When purchasing white onion for this recipe, you’ll want to be sure you’re getting the white onion with a white papery skin (not the yellow papery skin).  The white onions are much milder and sweeter and won’t overpower the other ingredients in this recipe.

If possible try to toss this at least 1 hour before serving to allow the flavors to blend.

  • Combine all dressing ingredients in a small bowl and mix well. Set aside.
  • Thinly slice onion and place in a bowl of cold water. (see note)
  • Cook pasta al dente according to package directions. Run under cold water to stop cooking.
  • Cut cucumber in half lengthwise and remove seeds using a spoon. Slice into thin slices.

Recipe Notes

Soaking the onions in cold water is optional but takes a bit of the "bite" out of the onion.

  1. Very comforting dish. I added a bit of extra salt and onion powder, as well as a small drizzle of olive oil to help thin the consistency. White beans make a good addition to bulk it up, too.5 stars

  2. Thank you so much was told I have high cholesterol totally need to change my eating habits.Whats really Good some ingredients have on hand not costly receipe5 stars

  3. I love your pasta salads! We attend, & also host many backyard events throughout the summer months, so it’s nice to always have something different to make. I’m always asked for the recipe, but I can’t take the credit, so I refer my friends to your terrific blog. Thanks for the terrific recipes. It’s quite evident that you put a lot of time & effort into your cooking blog, and it’s truly appreciated by those of us who take pride in what we put on our table. :-)5 stars

  4. I am so happy I found your site ! This was the best and different pasta salad I’ve ever had . I added diced celery & cut up rotisserie chicken . And soaking the onion …. Perfect !!!
    This was Delicious!
    I also made your ambrosia salad !
    Excellent !!!
    Thank you for your awesome recipes!!!5 stars

  5. A simple salad with big flavors. The dressing is perfect and I refrigerated it for a couple hours before putting everything together. Had to use dry dill because I could not find fresh but I dont think it took away from the salad. Using the english cucumber I didnt worry about seeds and did use the penne pasta. Will be making this often and using fresh dill this summer. Made and reviewed for the What’s on the Menu tag game.5 stars

  6. Hello!
    I want to make this for a shower with about 65 ladies. Can I make it a day or two in advance or is it better to toss everything a couple hours before the event? I want to make sure it still tastes fresh. 

    1. I’d say tossing the day of the event would be perfect. You could prepare the other ingredients ahead. Have a great shower!

  7. I made this tonight using fresh dill from my garden and cheese tortellini as my pasta and we LOVED it!  Thank you for the wonderful recipe! 5 stars

  8. This a wonderful cucumber pasta salad. Everyone loved it including my very picky grandson. He asked me to make it again so this is the second time this week that I have made this recipe!

    1. That should work just fine Dave. You may want to pat them dry if they seem more watery than long english cucumbers.

  9. Hello! Firstly, I’d like to thank you for posting these yummy salads! You found me a cheap and easy lunch to make and will last the week (until my family steals them -_-) Secondly, would it taste good if I were to add chicken into this or the Dill Pickle salad? I’m a meat lover! Thank you!

  10. Made this one and your dill pickle one for the first time today. oMG ! Girl they are amazing!!! I want them for myself and just want to make tuna salad for them tomorrow. Lol5 stars

    1. Wowzer! Followed exactly as written. I am impressed. The flavors are amazingly delightful. Into my “folder” of favorite recipes. Thank you so very much. YES!

  11. Made this for an office party and had so many compliments and a few coworkers even asked for the recipe. Glad I made it!5 stars

  12. We loved this salad. It has great flavor and was a perfect side for dinner. The dill and onion flavors are great with the light, refreshing taste of the cucumber. We will be making it again!5 stars

        1. I used regular pasta and I used Hellmann’s mayonnaise… the fresh dill and the sweet white onion (with white papery skin, not yellow) make a huge difference in the flavor as well. :)

  13. Love the basis of this recipe. I added approx a teaspoon of Beau Monde spice & some leftover shrimp cocktail. Excellent!!

  14. I was wondering, would it matter if I left the seeds in the cucumber. I know it said you can remove the seeds with a spoon. I always eat my cucumbers with the seeds.

    1. I have only made this recipe as written, so I am not sure how this would turn out. Should you decide to make it with the seeds, let me know how it turns out.

  15. I made this. LOVED it. I used bowtie pasta instead of penne. Still great. Used the “white onion” trick, and it made ALL the difference. You would be proud to put this on your table for every meal. If you want to cut calories, used low/no fat sour cream and mayo. Slice cherry toms in it to add that”splash” of color.

  16. Love this! I just made it and I Is delicious, I had a cucumber going bad and didn’t know what to do with it- All the ingredients are things I have in my pantry.

    Also a great way to stretch some simple ingredients when you’re budgeting!

  17. I don’t love sour cream and I also don’t have any right now! Do you have a suggestion for a substitute or if I should change anything if I were to leave it out?? This looks so good and I can’t find any other cucumber pasta salad recipes!

  18. Just made this and eating it now. SO DELICIOUS. Had a bunch of cucumbers from a family member and didn’t know what to make, so glad we tried this! Definitely going to make again for a bbq side dish!! Thank you for sharing this!!!!

  19. the dill pickle pasta salad was awesome and so easy to make. going to try the Hawaiian pasta salad and the creamy cucumber pasta salad

  20. I have red wine vinegar, apple cider vinegar, and rice vinegar..can I use one of those in place of the white vinegar?

  21. Holly,

    Will the salad with dessing hold up well if made the night before or will it become watery? I am making it for a pot luck birthday party tomorrow.

  22. Have made the dill pickle pasta salad 3 times in 2 weeks. It is to die for and doesn’t last more than 2 days in my household :D

  23. I just made the creamy cucumber pasta salad, and it is beyond yummy. I love it! I used a Vidalia onion. Thank you so much for this great recipe. 5 stars!5 stars

  24. This looks amazing! Do you think I can sub plain greek yogurt for the mayo and sour cream? (I’ve seen that substitution before in recipes.)

    1. You can certainly sub the sour cream for greek yogurt (and I often do). The mayo does add a little creaminess to this recipe so I would suggest keeping at least a small portion of mayo. If not, the texture/flavor will change slightly.

      1. Okay, mayo is no big problem. I just wanted to eliminate the sour cream portion! Thank you! Can’t wait to make this soon!

  25. Salads look so good I need to try because I love all Ingredients
    For how long its can stay in refrigerator
    Thank you Holly

  26. This looks so summery and fresh and cool. Have printed recipe and heading to store first thing tomorrow. Can’t wait to try it.
