Refreshing Cucumber and Potato Salad

If you’re looking for a fresh, simple salad that’s perfect for warm days or as a light side dish, this cucumber and baby potato salad is just what you need. It’s one of those recipes where the ingredients shine without fuss—small new potatoes cooked to tender firmness, crisp cucumber slices, and a creamy dressing made with sour cream or natural yogurt. The touch of vinegar adds a pleasant tang, while fresh dill (if you have it) brings a subtle herbaceous note.

The trick to keeping the cucumbers crisp and the flavors clean is soaking the cucumber slices in salted water before mixing everything together. This extra step really helps avoid sogginess and balances out the mild onion bite—if you prefer, soaking the diced onion can soften it further, especially if you like a milder taste. It’s an easy recipe that comes together quickly, makes a great make-ahead salad because the flavors deepen as it chills, and it’s always a hit alongside grilled meats or as part of a casual lunch.

Ingredients

1 pound (500 g) small new potatoes (baby potatoes)
2 medium cucumbers (fresher and firmer is better)
1 small onion (red or sweet onion preferred)
2/3 cup (150 g) sour cream or natural yogurt
2 tablespoons (30 ml) white vinegar or apple cider vinegar
1 tablespoon (15 ml) extra virgin olive oil
Salt, to taste
Freshly ground black pepper, to taste
1–2 tablespoons fresh dill, finely chopped (optional)
Cold water and salt (for soaking cucumbers)

Ingredient Notes

Baby potatoes are ideal here because they cook quickly and hold their shape well. If you can’t find small potatoes, use larger ones cut into bite-sized chunks. For the dressing, sour cream adds richness without being too tangy, but natural yogurt makes it lighter and a bit fresher. Using either white vinegar or apple cider vinegar works, depending on what you prefer—apple cider adds a mild fruitiness, while white vinegar keeps it clean and bright. Fresh dill is optional but highly recommended; it complements the creamy dressing and adds a lovely herbal freshness.

Kitchen Tools Needed

Medium pot for boiling potatoes
Large mixing bowls
Sharp knife and cutting board
Colander or sieve
Spoon or spatula for mixing

Step-by-Step Instructions

Cook the potatoes: Wash the baby potatoes well to remove any dirt. Place them in a pot and cover with salted water. Bring to a boil and cook for 20-25 minutes until tender but still firm when tested with a fork. Drain and let them cool completely before cutting into halves or quarters depending on their size.
Prepare the cucumbers: Wash and thinly slice the cucumbers. Place the cucumber slices in a bowl of cold water with about a teaspoon of salt. Soak for 10 minutes to remove any bitterness and help keep them crisp. Drain well and pat dry with a clean towel or paper towel.
Prepare the onion: Peel and finely chop the onion. If you prefer a milder onion flavor, soak the chopped onion in cold water for about 5-10 minutes, then drain before adding.
Make the dressing: In a small bowl, whisk together the sour cream or natural yogurt, vinegar, olive oil, salt, and freshly ground black pepper until smooth. Taste and adjust seasoning as needed.
Combine all ingredients: In a large bowl, gently mix together the cooled potatoes, cucumber slices, and finely chopped onion. Pour over the dressing and toss carefully to coat everything evenly. Be gentle to prevent the potatoes from breaking apart.
Chill and serve: Cover the salad and refrigerate for at least 30 minutes before serving to let the flavors meld. Just before serving, sprinkle fresh chopped dill over the top if you’re using it.

Pro Tips

Boil the potatoes with skins on to help them hold their shape and keep texture smooth.
Avoid overcooking potatoes; they should be tender but still firm to avoid a mushy salad.
Thoroughly draining and drying the cucumbers after soaking is key to preventing watery salad.
Adjust vinegar amounts to personal taste; start with less to avoid overpowering the dressing.
This salad benefits from resting in the fridge, allowing the flavors to develop fully.

Common Mistakes

Using overly soft or old potatoes can cause the salad to become mushy.
Not draining the cucumber slices well, which leads to a watery dressing.
Skipping soaking the onion if you’re sensitive to its sharpness.
Overmixing the salad can cause potatoes to break apart and become too soft.
Not chilling the salad before serving can result in less flavor and less refreshing taste.

Variations

Swap sour cream or yogurt with crème fraîche for a richer, slightly tangier dressing.
Add chopped fresh herbs like parsley or chives in addition to or instead of dill.
Include a few chopped radishes for an extra crunch and slight pepperiness.
For a bit of heat, add a pinch of cayenne pepper or some thinly sliced jalapeño.

Serving Suggestions

This salad works perfectly as a side dish for grilled chicken, fish, or pork during warm weather. It’s equally satisfying alongside barbecues or as part of a picnic spread. Serve chilled and consider pairing with crusty bread or light sandwiches for a simple, balanced meal.

Storage Instructions

Store leftover salad in an airtight container in the refrigerator for up to 2 days. The salad is best enjoyed fresh but will keep reasonably well chilled. Avoid storing longer as the cucumbers can soften and release moisture.

Reheating Tips

This salad is meant to be served cold or at room temperature. Reheating is not recommended as it will change the texture and flavor.

What if I don’t have sour cream?
