Why This Recipe Works

This cucumber and onion salad is easy to prepare and requires no cooking. The cucumbers provide plenty of crunch, while the onions add a sharp, savory bite. A simple vinegar-based dressing balances everything with a bright, slightly sweet flavor.

Letting the salad rest before serving gives the vegetables time to absorb the dressing, making every bite flavorful and refreshing.

Ingredients

For the Salad

• 4 medium cucumbers, thinly sliced
• 1 small yellow or white onion, thinly sliced
• ¼ cup fresh dill, chopped
• ½ teaspoon salt
• ¼ teaspoon black pepper

For the Dressing

• ½ cup white vinegar or apple cider vinegar
• 2 tablespoons granulated sugar
• 2 tablespoons olive oil
• ¼ teaspoon salt
• ¼ teaspoon black pepper

Equipment

• Large mixing bowl
• Small bowl or measuring cup
• Sharp knife or mandoline
• Whisk
• Serving bowl

Instructions

Step 1: Slice the Vegetables

Wash the cucumbers thoroughly and slice them into thin, even rounds. Thinly slice the onion as well. A mandoline can make it easier to achieve uniform slices, but a sharp knife works perfectly.

Step 2: Prepare the Dressing

In a small bowl, whisk together the vinegar, sugar, olive oil, salt, and black pepper. Continue mixing until the sugar is mostly dissolved and the dressing is well combined.

Step 3: Combine the Vegetables

Place the sliced cucumbers and onions in a large mixing bowl. Add the chopped fresh dill and gently toss everything together.

Step 4: Add the Dressing

Pour the prepared dressing over the cucumbers and onions. Toss gently until all of the vegetables are evenly coated.

Step 5: Chill the Salad

Cover the bowl and refrigerate the salad for at least 30 minutes before serving. For even more flavor, let it chill for 1 to 2 hours.

Step 6: Toss and Serve

Give the salad another gentle toss before serving. Taste and add a little more salt or pepper if needed. Serve chilled as a refreshing side dish.

Tips for the Best Cucumber and Onion Salad

• Use fresh, firm cucumbers for the best crunch and flavor.
• Slice the vegetables thinly so they absorb the dressing evenly.
• Don’t skip the chilling time because it allows the flavors to develop.
• Use fresh dill when possible for a brighter flavor.
• Adjust the sweetness depending on how tangy you prefer the dressing.
• Serve cold for the most refreshing texture and flavor.

Variations

You can easily customize this simple salad to suit your taste. Add thinly sliced bell peppers for extra crunch and color, or toss in a few halved cherry tomatoes for a fresh summer variation.

For a creamy cucumber and onion salad, replace the vinegar dressing with a mixture of sour cream, mayonnaise, vinegar, sugar, salt, and pepper. Fresh dill pairs especially well with the creamy version.

You can also add a small amount of red onion instead of yellow onion for a stronger color and slightly sharper flavor.

What to Serve With Cucumber and Onion Salad

This salad pairs beautifully with grilled chicken, burgers, barbecue, grilled fish, sandwiches, and roasted meats. It is also an excellent side for summer cookouts and potluck meals because it can be prepared ahead of time and served chilled.

Storage

Store cucumber and onion salad in an airtight container in the refrigerator for up to 3 days. The vegetables will become softer as they sit, so the salad is best enjoyed within the first day or two for maximum crunch.

Crisp cucumbers, flavorful onions, fresh dill, and a tangy-sweet dressing come together to create a refreshing side dish that takes only minutes to prepare.
