Fresh Ingredients for a Vibrant Cucumber and Onion Salad

Everything You Need

2 large cucumbers, thinly sliced
1 red onion, thinly sliced
2 tablespoons olive oil
1 tablespoon white wine vinegar
Salt and freshly ground black pepper to taste
2 teaspoons fresh dill, chopped (optional)
1 teaspoon granulated sugar (optional, helps balance acidity)
1/2 teaspoon garlic powder (optional)
1/4 cup fresh parsley, chopped (optional)
1 tablespoon lemon juice (optional, for extra brightness)
1/4 teaspoon red pepper flakes (optional, for mild heat)

Step-by-Step Instructions for the Perfect Cucumber Salad

How to Make It Perfectly

Slice the cucumbers and red onion into thin rounds. For the cucumbers, aim for slices about 1/8-inch thick—thin enough to be tender but thick enough to maintain their crunch. For a decorative touch, you can use a mandoline with a crinkle-cut blade.
If you prefer a milder onion flavor, place the sliced red onions in a bowl of ice water for about 10 minutes, then drain and pat dry. This helps reduce the sharpness while maintaining the onion’s crisp texture.
In a small bowl, whisk together olive oil, white wine vinegar, salt, and pepper. If using sugar, add it now and whisk until dissolved to help balance the acidity of the vinegar.
Place the sliced cucumbers and onions in a large bowl. Make sure your bowl is spacious enough to allow for gentle tossing without ingredients spilling over the sides.
Pour the dressing over the vegetables and toss gently to coat. Use two large spoons or salad tongs to ensure even distribution without bruising the delicate cucumber slices.
Add fresh dill if using and give a final toss. This is also when you’d add any optional herbs like parsley or seasonings like garlic powder.
Taste and adjust seasonings as needed. You might want a bit more salt, pepper, or vinegar depending on your preference.
Serve immediately for maximum crispness or chill for 15 minutes for enhanced flavor. The longer it sits, the more the flavors will meld together.

Storage Tips for Cucumber and Onion Salad

How to Store It Safely

The cucumber and onion salad recipe is best enjoyed fresh, but you can store leftovers in an airtight container in the refrigerator for up to 2 days. Glass containers work particularly well as they don’t absorb odors from the onions. Be aware that cucumbers will continue to release water as they sit, which may dilute the dressing over time.

If you know you’ll be making this salad in advance, consider salting and draining the cucumber slices before assembling the salad. Simply place the sliced cucumbers in a colander, sprinkle with a teaspoon of salt, and let stand for 30 minutes. Rinse thoroughly and pat dry before proceeding with the recipe. This step helps remove excess moisture and keeps the salad crisp longer.

Before serving stored cucumber salad, give it a gentle toss to redistribute the dressing. You may need to adjust the seasoning, as flavors can change during refrigeration. A fresh squeeze of lemon juice or splash of vinegar can revive the brightness of day-old salad. For the best texture after storage, you might want to drain off any excess liquid that has accumulated at the bottom of the container.

FAQs About cucumber and onion salad recipe

Should I peel the cucumbers for cucumber and onion salad?

Whether to peel cucumbers depends on your preference and the type of cucumber you’re using. English or Persian cucumbers have thinner, more tender skin and generally don’t need peeling. For regular garden cucumbers with thicker, sometimes bitter skin, peeling is recommended. If using organic cucumbers, you might opt to leave the nutritious skin on after a thorough wash.

How can I make my cucumber salad less watery?

To prevent a watery cucumber and onion salad recipe, salt the cucumber slices and let them sit in a colander for 30 minutes before assembling the salad. The salt draws out excess moisture, which you can then discard. Pat the cucumbers dry with paper towels before combining with the other ingredients and dressing. Additionally, serving the salad immediately or allowing it to marinate for only a short time (15-30 minutes) helps maintain the cucumber’s crisp texture.

Can I make cucumber and onion salad ahead of time for a party?

You can prepare components of the salad ahead of time, but for best results, assemble it no more than 2-3 hours before serving. Slice the cucumbers and onions and store them separately in the refrigerator. Make the dressing and keep it in a jar. When ready to serve, combine everything and add fresh herbs. If you must make it further in advance, use the salting method mentioned above to remove excess moisture from the cucumbers, which will help maintain texture longer.
