Cucumber Onion Salad Ingredients

I love how the crisp cucumbers and vibrant red onions create a refreshing crunch in this salad. Meanwhile, the apple cider vinegar dressing adds a tangy balance that ties everything together so nicely. Choosing fresh, high-quality produce always ensures brighter flavors and better texture in your cucumber onion salad.

• Cucumbers: Provide the hydrating, crisp base that keeps the salad light and refreshing.
• Red onion: Delivers a sharp, pungent bite that contrasts beautifully with the mild cucumbers.
• Apple cider vinegar: Forms the tangy backbone of the dressing, brightening the overall flavors.
• Water: Dilutes the vinegar slightly for a milder, more balanced dressing.
• Granulated sugar: Adds subtle sweetness to counter the acidity and enhance taste harmony.
• Fine sea salt: Seasons the mixture, drawing out natural flavors from the vegetables.
• Ground black pepper: Contributes a gentle spice that elevates the dressing’s depth.
• Red pepper flakes (optional): Introduce a spicy kick for those who enjoy a bit of heat.

Kitchen Tools You’ll Need

• Large mixing bowl: Holds the vegetables for easy tossing; a salad bowl works too.
• Small bowl or jar: For whisking the dressing; use a measuring cup if needed.
• Sharp knife and cutting board: Essential for thin slicing; a mandoline speeds up the process.
• Whisk or fork: To mix the dressing smoothly; shake in a jar for convenience.

How to Make Cucumber Onion Salad

Step 1: Prepare the Vegetables

Thinly slice the cucumbers into ¼-inch rounds for even texture. If your cucumbers have thick skins, peel them first to avoid toughness. Slice the red onion into thin half-moons and add it to the cucumbers in a large mixing bowl. This quick prep keeps the easy salad vibrant and crisp.

Step 2: Whisk the Dressing

In a small bowl or jar, combine the apple cider vinegar, water, granulated sugar, fine sea salt, and ground black pepper. Whisk until the sugar dissolves and everything blends smoothly. This simple vinegar dressing takes just moments and provides the tangy refreshment.

Step 3: Toss and Coat

Pour the dressing over the cucumber and onion mixture in the bowl. Gently toss to coat every piece evenly, ensuring the flavors distribute well. The gentle mixing prevents bruising the delicate slices.

Step 4: Chill for Flavor Development

Refrigerate the salad for at least one hour before serving. This resting time allows the ingredients to meld, intensifying the quick side dish’s taste. Serve it chilled for the best refreshing experience.

Tips for Success

• Choose firm, fresh cucumbers to maintain crunch in your cucumber onion salad.
• Slice vegetables thinly for better absorption of the vinegar dressing.
• Whisk the dressing thoroughly so sugar and salt dissolve evenly.
• Chill for a full hour to let flavors develop fully.
• For spice, stir in a pinch of red pepper flakes during mixing.
• Taste and adjust seasoning before chilling if needed.

How to Store Cucumber Onion Salad

I always store my cucumber onion salad in an airtight container right in the refrigerator after preparing it. This keeps it fresh and flavorful for up to two days. However, I find it tastes best within the first day to enjoy that maximum crispness. The chill preserves the refreshing texture nicely. Just avoid leaving it out at room temperature for long periods. Freezing isn’t ideal, since it makes the cucumbers soggy when thawed. For leftovers, I give it a quick stir before serving it chilled again.

Serving Suggestions for Cucumber Onion Salad

• I pair it with grilled chicken or fish for a light summer meal that feels effortless after a busy day.
• Serve alongside barbecue ribs to cut through the richness and refresh every bite.
• Garnish with fresh dill for added color and a hint of herbiness that brightens the plate.
• Enjoy with iced tea or lemonade—these drinks complement the tangy flavors perfectly.
• Present in a clear bowl to showcase the vibrant slices and impress your family or guests.
