Bright, crisp ingredients that balance tangy vinegar and fresh herbs for a refreshing summer salad.
| Ingredient | Amount | Notes |
|---|---|---|
| Persian Cucumbers 🥒 | 2 whole | Thinly sliced lengthwise |
| Red Onions 🧅 | 1 whole | Thinly sliced, soak 5 mins |
| Apple Cider Vinegar 🍏 | ¼ cup | Raw, unfiltered preferred |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | Light, fruity variety |
| Fresh Dill 🌿 | ¼ cup | Chopped, stems removed |

| Granulated Sugar 🍯 | 1 tbsp | Or maple syrup for depth |

Persian cucumbers are the secret to staying crisp—English or Kirby work too, but avoid seedless varieties which get mushy. Whole Foods or local farms often have the best selection, but the regular grocery store cucumbers work fine if they're firm and unblemished. Red onions add the sharp bite, but yellow or white onions work in a pinch—just soak them longer to mellow the flavor. For the vinegar, Bragg or Texas Pete are my go-tos, but any raw, unfiltered apple cider vinegar will do. The extra-virgin olive oil should be light and fruity—California Gold or Colavita are solid choices, but don't splurge on fancy oils here unless you love the flavor.
No fresh dill? Fresh parsley or chives work in a pinch, though dill's anise notes are key. Running short on sunflower seeds? Pumpkin seeds or toasted pine nuts add similar crunch. The sugar balances the vinegar—maple syrup or agave work beautifully if you prefer natural sweeteners. For extra depth, add 1 tsp Dijon mustard to the dressing. Always taste before serving—adjust vinegar to salt ratio to your preference. The salad keeps best in the fridge for 2-3 hours, but cucumbers start to soften after that, so make it fresh if possible.
This salad thrives on freshness—prep components separately until ready to toss. Store dressing ingredients in a sealed jar for up to 2 weeks in the fridge. The cucumbers and onions can sit in separate containers for 4 hours before mixing, but add herbs and seeds last minute. For meal prep, assemble everything except seeds and herbs, then add those just before serving to preserve texture. The flavors actually improve after sitting for 30 minutes as everything melds—perfect for picnic prep!

Step-by-step instructions for cucumber and onion salad with apple cider vinegar
Here's the method for a refreshing, tangy salad that balances crisp vegetables with bright vinegar flavors.
Prepare the Vegetables for Maximum Crunch
Cut the 2 whole Persian cucumbers in half lengthwise, then slice each half into thin strips about ⅛-inch thick. This uniform slicing ensures even distribution in the salad. Transfer the cucumber slices to a large mixing bowl and set aside.
Peel the 1 whole red onion and slice it into thin rings. Place these in a separate bowl and immediately cover with cold water for 5 minutes. This soaking step mellows the onion's sharp bite while keeping it crisp. Drain thoroughly before adding to the cucumbers.
Create the Tangy Dressing Base
In a small bowl, whisk together the 0.25 cup apple cider vinegar, 1 tablespoon granulated sugar, 0.5 teaspoon sea salt, and 0.25 teaspoon black pepper. Let this mixture sit for 2 minutes to allow the sugar to fully dissolve. The sugar helps balance the vinegar's acidity while enhancing the overall flavor profile.
Stir in the 0.25 cup extra-virgin olive oil and 1 tablespoon lemon juice until completely emulsified. The oil should coat the back of a spoon, indicating a proper dressing consistency. If you prefer a smoother texture, strain the mixture through a fine-mesh sieve to remove any undissolved sugar granules.
Combine Ingredients and Chill for Freshness
Add the drained red onion slices to the cucumbers in the mixing bowl. Pour the dressing over the vegetables and gently toss with a wooden spoon to ensure even coating. Fold in the 0.25 cup chopped fresh dill and 2 cloves minced garlic cloves (if using), distributing them evenly throughout the salad.
Transfer the salad to an airtight container and refrigerate for at least 30 minutes before serving. This chilling time allows the flavors to meld together while maintaining the vegetables' crisp texture. The longer it rests, the more vibrant the flavors become, especially the vinegar's tang.
Toast the Seeds and Garnish for Texture
While the salad chills, toast the 0.25 cup sunflower seeds in a dry skillet over medium heat for 3-4 minutes, stirring constantly until golden brown. Watch closely—they burn quickly. Transfer to a plate to cool, then sprinkle evenly over the salad just before serving.
Finally, garnish with the 0.125 cup chopped fresh parsley. The parsley adds a fresh, herbal note that complements the bright vinegar flavors. Serve immediately for the best texture and flavor combination, or store in the refrigerator for up to 2 days for a quick, refreshing side dish.
Pro Tips For Making Cucumber And Onion Salad Recipe With Apple Cider Vinegar
- Slice Onions Thin: A mandoline or sharp knife makes this easier—aim for paper-thin slices so they soften just enough without turning mushy. I used to chop them unevenly, and the texture always felt off.
- Soak Onions 10 Minutes: Toss red onion slices in cold water for 10 minutes before draining. This mellows the bite and prevents the salad from tasting harsh even after sitting. (Yes, it’s an extra step, but it’s worth it.)
- Dress Salad Last: Toss cucumbers, onions, and dill first, then add vinegar and oil right before serving. The acidity draws out moisture faster, so waiting keeps everything crisp. Trust me, this isn’t the time to rush.
- Use Cold Vinegar: Chill the apple cider vinegar in the fridge for 15 minutes before mixing—it sharpens the flavor and prevents the salad from heating up. Warm vinegar makes the whole dish taste dull.

Frequently asked questions
Can I use regular vinegar instead of apple cider vinegar?
While you can substitute white or red wine vinegar, apple cider vinegar adds a unique depth and subtle sweetness that complements the cucumbers and onions perfectly. For a similar flavor, try balsamic vinegar, but reduce the sugar in the dressing to ½ tablespoon since balsamic is already slightly sweet. The tangy brightness is key to balancing the salad's freshness.
How do I keep the cucumbers from getting soggy?
Slice the cucumbers ⅛-inch thick and pat them dry with a paper towel before adding to the salad. Avoid cutting them too far in advance—prepare the salad just before serving or store the cucumbers and onions separately in the fridge for up to 4 hours. The acidity in the vinegar helps preserve crispness, but the longer it sits, the softer the cucumbers become.
Can I make this salad ahead of time?
Yes, but with a few adjustments! Prep the dressing and store it separately in an airtight container for up to 2 weeks. Keep the cucumbers and onions dry in separate containers for 4 hours max before mixing. Add fresh herbs and toasted seeds just before serving to maintain crispness. The flavors actually improve after 30 minutes of chilling, so it's perfect for meal prep!
What’s the best way to adjust the dressing for spice lovers?
For extra heat, add ½ teaspoon of red pepper flakes or 1 teaspoon of hot sauce (like Sriracha) to the dressing. If you love smoky flavors, swap ½ teaspoon of smoked paprika** for the black pepper. Start with small amounts—vinegar-based dressings can become overwhelming if overdone. Taste as you go and adjust gradually.
Is this salad gluten-free or vegan?
This recipe is naturally vegan and gluten-free as written, with no animal products or wheat-based ingredients. Just double-check your sunflower seeds or other add-ins for hidden gluten if you're highly sensitive. The dressing is also safe for those avoiding dairy or eggs, making it a versatile, inclusive dish for any dietary need.
