Easy Homemade Cucumber Salad Recipe From Scratch

This cucumber salad is the side dish I reach for most from May through September. Most versions wilt within the hour or taste flat from overdressing. Mine uses fresh dill, rice vinegar, and red onion for a crisp, bright result that holds up for hours.

Why This Cucumber Salad Works

Rice vinegar is the key to a bright cucumber salad that stays fresh. It’s lighter and slightly sweeter than white vinegar, so it coats each slice without overpowering the cucumber. The result is a tangy dressing that clings to every piece without making the bowl watery.

The ratio of oil to vinegar matters here. Too much oil makes the dressing heavy and turns cucumbers slick. I use three parts vinegar to one part oil, which keeps everything light and easy to eat.

Red onion adds sharp contrast to the cool cucumber. Sliced paper-thin, it softens in the dressing within minutes. The purple-pink color also makes this cucumber salad more visually striking in the bowl.

Fresh dill is the defining flavor in this recipe. Its faintly sour, herbal note pairs perfectly with the cool cucumber and tangy vinegar. I use at least two tablespoons — less and the dill gets lost.

Ingredients

• 1 1/2 pounds English cucumbers (about 2 medium), thinly sliced
• 1/2 small red onion, thinly sliced into half-moons
• 3 tablespoons rice vinegar
• 1 tablespoon olive oil
• 1 teaspoon granulated sugar
• 3/4 teaspoon kosher salt
• 2 tablespoons fresh dill, roughly chopped
• 1/4 teaspoon red pepper flakes

What You Need for Cucumber Salad

English cucumbers — these have thinner skin and smaller seeds than standard cucumbers. You can slice and eat them without peeling, which saves a step. Persian cucumbers work equally well at a slightly smaller size.

Red onion — adds sharp bite and color that balances the cool cucumber. Slice it as thin as possible so it softens quickly in the dressing. If raw onion is too strong, rinse the slices under cold water for 30 seconds to mellow the flavor.

Rice vinegar — lighter and slightly sweet compared to white vinegar. It brightens the cucumber salad without turning it harsh or sharp. White wine vinegar is the closest substitute and works at the same amount.

Olive oil — rounds out the vinegar and adds body to the dressing. Any neutral oil like avocado oil or light olive oil works if you prefer a milder flavor in the background.

Granulated sugar — just one teaspoon balances the tang without making the dressing noticeably sweet. Honey or maple syrup substitute at the same amount. Skip it entirely if you prefer a sharper, more acidic dressing.

Kosher salt — seasons the dressing and draws a small amount of moisture from the cucumbers. Use kosher, not table salt. Table salt is nearly twice as salty by volume, so if you substitute, use half as much.

Fresh dill — the defining herb in this cucumber salad. Its slightly sour, anise-forward flavor is the best match for cool cucumber. Dried dill substitutes at 1 teaspoon, but fresh gives a more vibrant color and flavor.

Red pepper flakes — optional, but adds a gentle warmth at the finish. Leave them out for a completely mild cucumber salad. Double the amount if you like a bit of heat alongside the cool crunch.

How to Make Cucumber Salad

1. Slice cucumbers into thin rounds, about 1/8 inch thick. Use a mandoline for perfectly even slices.
2. Slice red onion into thin half-moons.
3. Whisk rice vinegar, olive oil, sugar, and salt in a large bowl until the sugar dissolves.
4. Add cucumbers, red onion, and dill to the bowl.
5. Toss until every slice is evenly coated in dressing.
6. Taste and adjust salt or vinegar as needed. Serve right away or chill for 10 minutes.

Cucumber Salad Variations

Creamy Cucumber Salad

Swap the vinegar-oil dressing for 1/4 cup sour cream, 1 tablespoon white wine vinegar, a pinch of sugar, and 3/4 teaspoon salt. The sour cream coats each slice in a thick, cool layer that’s richer than the vinaigrette version. This style is closer to a German cucumber salad and pairs especially well with grilled chicken or pork. You can also use plain Greek yogurt for a lighter result with more tang.

Asian Cucumber Salad

Replace the rice vinegar with 2 tablespoons of seasoned rice vinegar and swap the olive oil for 1 teaspoon of sesame oil. Add 1 teaspoon of grated fresh ginger, 1 small clove of minced garlic, and swap the dill for 1 tablespoon of toasted sesame seeds. The sesame and ginger give this cucumber salad a nutty, warming depth. A small drizzle of chili oil at the end ties all the flavors together.

Greek Cucumber Salad

Add 1/2 cup halved cherry tomatoes, 1/4 cup crumbled feta cheese, and 10 sliced Kalamata olives to the base cucumber salad. Swap the rice vinegar for red wine vinegar and replace the dill with 1/2 teaspoon dried oregano. Serve at room temperature for the best flavor — the feta softens slightly and works into the dressing. A squeeze of lemon over the top just before serving brightens the whole bowl.

Spicy Cucumber Salad

Double the red pepper flakes and stir in 1 teaspoon of chili crisp or sambal oelek. The heat builds slowly and contrasts the cool, crisp cucumber in every bite. This version works as a condiment-style side alongside rice bowls, grilled fish, or cold noodles. Keep the sugar in the dressing — it helps balance the chili heat and keeps the flavor from turning one-dimensional.

Tips for the Best Cucumber Salad

• Use English or Persian cucumbers. Both have thin skin you can eat and far fewer seeds than standard cucumbers.
• Slice as thin as possible. A mandoline set to 1/8 inch gives even slices that absorb the dressing more consistently than hand-cut rounds.
• I always taste the dressing before adding the cucumbers. Adjust salt first, then vinegar.
• Serve within two hours. Cucumbers release water as they sit and the dressing becomes thin over time.
• For a sweeter dressing, add 1/2 teaspoon more sugar. For more tang, add 1 extra teaspoon of vinegar.
• Chill the cucumber slices for 15 minutes before tossing. Cold cucumbers stay crisper in the finished salad.
• Add the dill last, right before serving. This keeps the color bright green rather than dull and wilted.

Make Ahead & Storage

This cucumber salad keeps in the fridge for up to two days in a sealed container. By day two, the cucumbers soften slightly but the flavor deepens as the dressing soaks in. I prefer it fresh or within the first two hours for the best crunch and color.

To prep this cucumber salad ahead, slice the cucumbers and make the dressing separately. Combine them up to 30 minutes before serving. The cucumbers hold their texture much better when they haven’t been sitting in the dressing for hours. Do not freeze this salad — cucumbers turn mushy once thawed.

Common Questions

How do you keep cucumber salad from getting watery?

Serve within two hours of tossing. Cucumbers release water as they sit, which dilutes the dressing over time. If you need to prepare ahead, keep the sliced cucumbers and dressing in separate containers until just before serving. You can also salt the cucumber slices, wait 10 minutes, and pat them dry before tossing to draw out the extra moisture upfront.

What type of cucumbers are best for cucumber salad?

English or Persian cucumbers are my top choice. Both have thin skin you can eat without peeling and fewer seeds than garden cucumbers. Regular cucumbers work but peel them first and scoop out the seeds with a spoon. The thinner the skin, the better the final texture in the salad.

Can I use white vinegar instead of rice vinegar?

You can, but white vinegar is sharper and stronger. Use 2 tablespoons instead of 3 and taste as you go. Apple cider vinegar is a closer substitute to rice vinegar in both flavor and acidity. White wine vinegar works well at the same amount as the original recipe.

Can I make cucumber salad without sugar?

Yes. Leave the sugar out entirely or swap it for a small drizzle of honey at the same amount. The dressing will taste sharper without it, but still pairs well with the cucumber. If the flavor feels too acidic, add a splash of cold water to dilute slightly and balance the vinegar.

This cucumber salad takes 10 minutes and goes with almost everything you’re grilling this summer. Save this recipe and pin it for your next cookout, picnic, or weeknight dinner.
