Why This Recipe is Special

At its heart, this Simple Cucumber and Onion Salad is the ultimate definition of simplicity: raw ingredients, bold flavors, and minimal prep.

This recipe is also incredibly versatile, making it easy to adapt based on your taste or pantry.

Ingredients and Preparation

Cucumbers – Provide the crisp texture and refreshing base of the dish. English cucumbers are ideal due to their thinner skins and fewer seeds, but regular cucumbers work just as well if peeled and deseeded.

Sweet onions – Add mild sharpness and aromatic depth. Vidalia or red onions can be used, or even shallots if you’re looking for a softer bite.

Vinegar (typically white or apple cider vinegar) – Offers the tart backbone of the dressing, cutting through the sweetness and enhancing the cucumber’s freshness. You can substitute with lemon juice for a citrus twist.

Sugar – Balances the vinegar with a touch of sweetness. Honey or agave syrup are great alternatives if you want to avoid refined sugar.

Salt and black pepper – Essential for drawing moisture out of the cucumbers and enhancing overall flavor. Freshly cracked pepper gives an extra aromatic punch.

Optional: Fresh herbs like dill or parsley – Add fragrance and elevate the dish with a garden-fresh note.

Step-by-Step Instructions

Step 1 Begin by thoroughly washing your cucumbers and onion. Slice the cucumbers into thin rounds—aim for uniform thickness to ensure even marination. Peel and slice the onion thinly; use a sharp knife or mandoline for best results.

Step 2 Place the sliced cucumbers and onions into a large bowl. If the onions feel too strong, soak them in cold water for 10 minutes and drain before mixing.

Step 3 In a separate small bowl, whisk together your vinegar, sugar, salt, and pepper until the sugar dissolves completely. This forms your quick dressing.

Step 4 Pour the dressing over the cucumber and onion mixture. Stir gently to ensure everything is evenly coated. The salt will start to draw moisture out of the cucumbers, creating a flavorful, tangy brine.

Step 5 Cover the bowl and refrigerate for at least 30 minutes before serving. This resting time allows the flavors to meld beautifully. If you’re short on time, even 10 minutes in the fridge will make a noticeable difference.

Step 6 Right before serving, give the salad a gentle stir and taste. Adjust seasoning as needed, and sprinkle in chopped herbs if using.

Beginner Tips and Notes

If your cucumbers turn mushy after storing, it’s likely due to over-marinating or using overly mature cucumbers. Stick to fresh, firm ones and consume within 2–3 days. If your onions taste too sharp, try the water soak trick mentioned earlier or use red onions for a gentler bite.

To save time, slice the vegetables ahead and store them separately. Combine with dressing just before serving to retain crispness. Don’t have a mandoline? A potato peeler works in a pinch for delicate cucumber slices.

Serving Suggestions

This salad pairs beautifully with grilled lemon herb chicken or baked fish for a refreshing contrast. For a complete easy sheet pan dinner, roast chicken thighs and add this salad as a cool, crunchy side.

Want a creamier twist? Add a dollop of Greek yogurt or sour cream just before serving. Leftovers can be stored in the fridge for up to 48 hours—just keep in mind that the veggies may soften slightly.
