Cucumber Salad Recipe With Sour Cream, Vinegar, and Sugar: Cool Refreshment for Picnics and BBQs

This cucumber salad recipe with sour cream, vinegar, and sugar is the perfect cool side dish for summer picnics, backyard BBQs, or any gathering where fresh, tangy flavors are welcome.

The secret lies in the balance of creamy sour cream, sharp vinegar, and just the right amount of sugar to enhance the cucumbers' natural sweetness without overpowering them. I've tested countless variations, and this one consistently delivers that ideal crunchy texture with a dressing that clings perfectly to each slice.

The preparation is straightforward but requires attention to detail—thinly slicing the cucumbers ensures they stay crisp, while the dressing mixture of sour cream, vinegar, and sugar creates a harmonious blend of tangy, creamy, and slightly sweet notes.

A sprinkle of fresh dill or chopped herbs adds brightness, and optional toasted nuts or seeds can introduce a satisfying crunch. The salad tastes even better after chilling for at least 30 minutes, allowing the flavors to meld together beautifully.

What you'll end up with is a refreshing, crowd-pleasing side dish that pairs perfectly with grilled meats, sandwiches, or even as a light appetizer.

The creamy dressing coats the cucumbers just enough to keep them tender without making them soggy, while the vinegar and sugar create a bright, balanced flavor that cuts through richer dishes. This recipe is foolproof, versatile, and guaranteed to become a staple at your summer gatherings.

Serve it chilled alongside burgers, chicken, or as part of a charcuterie board. The simplicity of the ingredients makes it easy to customize—add a pinch of salt, a dash of garlic powder, or even a splash of lemon juice to suit your taste.

Here’s how to make it perfectly every time.

Ingredients for cucumber salad recipe with sour cream vinegar and sugar

Fresh cucumbers and creamy sour cream star this refreshing summer salad—perfect for picnics and BBQs.

The cucumbers are the star, so choose English cucumbers—they're longer and less seedy than Persian types. Most grocery stores carry them year-round, but local farmers markets in summer have the freshest, crispest ones. Look for ones that are firm to the touch and have a vibrant green color—no soft spots. I always buy a few extra because they keep well in the fridge for 5-7 days. If you can't find English cucumbers, Persian cucumbers work too, but you'll need to halve them lengthwise before slicing. For the sour cream, full-fat makes the biggest difference in creaminess—don't skimp here. Great Value or Kroger brands are reliable and affordable.

No sour cream? Greek yogurt works perfectly—just add an extra pinch of salt to balance the tang. Short on dill? Fresh parsley or chives add brightness too. The vinegar should be white vinegar for classic flavor, but apple cider vinegar adds a fruity twist. If you want to make this ahead, prep everything except the cucumbers (store dressing separately) and slice the cucumbers just before serving to keep them crisp. For extra crunch, toast your walnuts in a dry pan for 3-4 minutes until fragrant. No walnuts? Pepitas or sunflower seeds are great substitutes. The sugar amount can be adjusted—start with 2 tbsp and add more if you like it sweeter.

This salad tastes even better after chilling for at least 30 minutes, so make it ahead if you're hosting. Store the dressing separately in an airtight container for up to 3 days—just mix before serving. The cucumbers stay crisp for 2 days in the fridge if stored in a sealed container with paper towels to absorb moisture. For a make-ahead picnic, pack the dressing and cucumbers separately and toss right before eating. The walnuts and herbs can be added fresh right before serving to keep them from getting soggy. Leftovers? The dressing keeps for 5 days in the fridge, but the cucumbers get watery after a day—best enjoyed fresh.

Step-by-step instructions for cucumber salad with sour cream and vinegar

This tangy, creamy cucumber salad comes together in minutes with no cooking required.

Begin by washing the 2 large English cucumbers thoroughly under cool water to remove any dirt or wax. Using a sharp chef's knife, carefully slice them lengthwise into thin strips—about ⅛-inch thick. I like to work with the cucumbers whole first, then slice them in half lengthwise before cutting into strips for easier handling.

Place the sliced cucumbers in a large mixing bowl. The slices should be uniform in thickness to ensure even distribution of flavor throughout the salad. If you prefer a more rustic texture, you can leave them slightly thicker, but thin slices create a more elegant presentation and allow the dressing to penetrate better.

In a medium bowl, whisk together the 0.5 cup sour cream, 0.25 cup white vinegar, 2 tablespoons granulated sugar, 1 tablespoon lemon juice, 0.5 teaspoon salt, 0.25 teaspoon black pepper, and 0.25 teaspoon garlic powder until the sugar dissolves completely and the mixture is smooth. The dressing should have a thick, creamy consistency—this is what will coat each cucumber slice perfectly.

Taste the dressing before combining with the cucumbers. If you prefer it sweeter, add a bit more sugar. If it needs more tang, add a splash of additional white vinegar. The balance between the creamy sour cream and the sharp vinegar is key—this is where the salad gets its signature flavor.

Pour the dressing over the sliced cucumbers in the mixing bowl. Using a large spoon or spatula, gently toss everything together until the cucumbers are evenly coated. Be careful not to overmix—you want the cucumbers to remain intact rather than becoming mushy. Add the 0.25 cup chopped fresh dill and 0.25 cup chopped toasted walnuts at this stage for texture and freshness.

Transfer the cucumber salad to an airtight container and refrigerate for at least 1 hour before serving. This chilling time allows the flavors to meld together beautifully, and the cucumbers to soften slightly while still maintaining their crisp texture. If you're short on time, you can serve it immediately, but the flavors will be even more harmonious after chilling.

Before serving, give the salad one final toss to redistribute the dressing. The cucumbers should be evenly coated with a glossy, creamy layer. Garnish with an additional sprinkle of fresh dill and a few extra toasted walnuts on top for presentation. This salad is perfect for picnics, BBQs, or as a refreshing side dish for grilled meats.

Serve immediately while the cucumbers are still crisp. The salad will keep well in the refrigerator for up to 2 days, but the texture may become slightly softer over time. If you notice the cucumbers releasing too much liquid, drain any excess before serving to maintain the perfect balance of flavors and textures.

Pro cooking tips for great cucumber salad recipe with sour cream vinegar and sugar

Slice Like a Pro

Uniform slices are key to keeping your cucumbers crisp. Use a sharp chef's knife and slice the cucumbers lengthwise into ⅛-inch thick strips—this prevents them from getting soggy. I like to halve the cucumbers lengthwise first, then slice them into strips for easier handling.

A mandoline slicer with a ⅛-inch blade works perfectly if you're making this often, but a steady hand with a sharp knife does the job just as well. 🥒

Dressing Balance

The magic happens in the dressing ratio. Whisk together ½ cup sour cream, ¼ cup white vinegar, and 2 tbsp sugar until smooth—this creates the perfect creamy-tangy-sweet balance.

Taste before adding to the cucumbers: if it needs more tang, add 1 tsp extra vinegar; if it's too sharp, stir in ½ tsp more sugar. The dressing should coat the cucumbers lightly but not overwhelm them.

I always use full-fat sour cream for the best texture—it’s worth the splurge!

Chill Time Matters

Never skip chilling! Transfer the salad to an airtight container and refrigerate for at least 1 hour (up to 4 hours for deeper flavor). This lets the cucumbers soften slightly while staying crisp, and the dressing clings perfectly.

Pro tip: If you're prepping ahead, store the dressing and cucumbers separately in the fridge, then toss just before serving. This keeps the cucumbers extra crisp for up to 2 days. ❄️

Texture Tricks

Add toasted walnuts for crunch—toss them in a dry pan for 3-4 minutes until fragrant. For extra brightness, fold in ¼ cup chopped fresh dill right before serving. If you want to make it ahead, store the herbs and nuts separately and add them fresh before eating.

A sprinkle of everything bagel seasoning or smoked paprika adds a savory twist if you're feeling adventurous!

Preventing Sogginess

Cucumbers release water as they sit, so drain any excess liquid before serving. If your salad looks watery, line the bowl with a paper towel before adding the cucumbers, or gently press them with a clean kitchen towel to remove moisture.

For a drier salad, slice the cucumbers just before mixing with the dressing. This keeps them crisp for hours—perfect for picnics or BBQs where you can’t refrigerate immediately.

Make-Ahead Mastery

Prep the dressing 2 days ahead and store it in an airtight container in the fridge. Slice the cucumbers 1 day ahead and keep them dry in a sealed container with a paper towel. When ready to serve, toss everything together and chill for 30 minutes.

This method ensures maximum crispness and flavor without the last-minute rush. Pack the dressing and cucumbers separately in a cooler for picnics—they’ll stay fresh for 6-8 hours! 💡
