Ingredients

For the Salad

• 3 English cucumbers – The crisp, refreshing base of the salad. English cucumbers work especially well because they have thin skin, fewer seeds, and a tender crunch.
• 1 red onion – Adds sharpness, color, and just enough bite to balance the sweetness of the dressing.

For the Vinegar Dressing

• 1 cup apple cider vinegar – Brings bright, tangy flavor and gives the salad its signature marinated taste.
• 1/2 cup sugar – Balances the vinegar with sweetness and helps create that classic sweet-and-sour cucumber salad flavor.
• 1/2 cup water – Softens the acidity of the vinegar so the dressing tastes balanced rather than too sharp.
• 1 teaspoon salt – Draws out flavor from the cucumbers and seasons the dressing.
• 1/4 teaspoon pepper (optional) – Adds a mild touch of warmth and savory depth.

How to Make Cucumber Vinegar Salad

1. Slice the Cucumbers

Start by slicing the cucumbers into thin, even rounds. Thin slices work best because they absorb the dressing more quickly and give the salad that classic delicate texture.

If you like, you can use a sharp knife or a mandoline for especially even slices.

2. Slice the Onion

Cut the red onion in half, then slice it into very thin strips.

Thin onion slices blend beautifully into the salad and soften slightly as they marinate, giving you onion flavor without overwhelming each bite.

3. Combine the Vegetables

Place the sliced cucumbers and red onion in a large mixing bowl.

Toss them together lightly so the onion is distributed evenly throughout the cucumbers.

4. Make the Vinegar Dressing

In a separate medium-sized bowl, combine the apple cider vinegar, sugar, water, salt, and pepper if using.

Stir well until the sugar dissolves completely. This creates the sweet-tangy dressing that gives the salad its signature flavor.

5. Toss Everything Together

Pour the vinegar mixture over the cucumbers and onions.

Stir until all of the cucumber slices are evenly coated in the dressing. Make sure the onions are submerged as much as possible too, so they soften and absorb the flavor while chilling.

6. Chill the Salad

Cover the bowl and refrigerate for at least 20 minutes.

This short marinating time makes a big difference. The cucumbers absorb the sweet-tangy dressing, the onions mellow slightly, and the whole salad becomes much more flavorful.

7. Drain and Serve

Before serving, drain off the excess liquid and transfer the salad to a serving bowl.

Serve it cold for the best texture and flavor.

Tips for Success

• Slice the cucumbers thinly so they soak up the dressing quickly and evenly.
• Use English cucumbers if possible for the best texture and fewer seeds.
• Let the salad chill before serving so the flavors have time to develop.
• Taste the dressing before pouring and adjust the sugar if you want it sweeter or more tangy.
• Add a splash more water if the vinegar tastes too sharp for your preference.
• Drain before serving so the salad isn’t too watery on the plate.

Equipment Needed

• Sharp knife or mandoline – For slicing the cucumbers and onion thinly.
• Large mixing bowl – For combining the cucumbers and onion.
• Medium bowl – For whisking or stirring together the vinegar dressing.
• Spoon or tongs – For tossing the salad.
• Serving bowl – For presenting the finished salad after draining.

Recipe Variations

1. Add Fresh Herbs

Mix in chopped fresh dill, parsley, or chives for extra freshness and a garden-inspired flavor.

2. Add Tomatoes

Toss in halved cherry tomatoes or chopped tomatoes to turn it into a cucumber tomato onion vinegar salad.

3. Make It Creamy

For a creamy variation, stir in a spoonful of sour cream or Greek yogurt after draining the salad.

4. Add Feta Cheese

Crumbled feta adds a salty, creamy contrast that pairs beautifully with the tangy dressing.

5. Give It a Little Heat

Add a pinch of red pepper flakes for a subtle spicy kick.

Serving Suggestions

This Cucumber Vinegar Salad is a versatile side dish that pairs well with all kinds of meals. Serve it with:

FAQs

Can I make cucumber vinegar salad ahead of time?

Yes. This salad is great for making ahead because the cucumbers and onions soak up more flavor as they chill.

How long does it last in the refrigerator?

Store it in an airtight container in the fridge for up to 3 days. The cucumbers will soften slightly over time, but the salad will still taste great.

Do I have to use English cucumbers?

No. Persian, garden, or regular slicing cucumbers also work. If using regular cucumbers with thick or waxy skin, peeling them is a good idea.

Can I use a different vinegar?

Absolutely. White vinegar, white wine vinegar, red wine vinegar, or rice vinegar can all work in place of apple cider vinegar.

Can I make it less sweet?

Yes. You can reduce the sugar to suit your taste or add a little extra water if you want a milder dressing.

Should I serve it with the liquid or drain it first?

This comes down to personal preference, but draining it before serving usually makes it easier to eat and keeps it from being too watery on the plate.
