Ingredients for cucumber tomato onion apple cider vinegar salad

Fresh, vibrant ingredients that burst with summer flavor—perfect for any meal.

The cucumbers and tomatoes are the stars here—pick firm, bright ones at the store. Trader Joe's and local farmers markets have the best selection, but any grocery store will do if you grab them early in the day. For the onion, red or yellow both work, but red adds a touch of sweetness that pairs perfectly with the vinegar. Fresh dill and mint? Don't skip them—they take this salad from good to restaurant-quality. If you can't find fresh dill, dried works in a pinch (use half the amount). The apple cider vinegar should be raw and unfiltered—it's got more flavor and nutrients. Bragg or Texas Pete are solid choices if you're not sure which to pick.

No fresh dill? Dried oregano or tarragon can stand in, but you'll miss that bright, fresh flavor. Running low on lemon juice? Lime juice works too, though it's a bit more tart. Want to make this vegan? Swap the honey for maple syrup or agave nectar—it keeps the sweetness without compromising the tang. The dressing ratio is key: 1 part vinegar to 2 parts oil gives you that perfect balance. If you prefer it sweeter, add another teaspoon of honey or maple syrup. For extra crunch, toss in a handful of toasted sunflower seeds—they add texture and protein without overpowering the fresh flavors.

This salad stays crisp for 2-3 days in the fridge if you keep the dressing separate. Store the veggies in an airtight container and the dressing in a small jar—toss them together right before serving. Prep ahead by chopping everything the night before, but don't add the dressing until you're ready to eat. The flavors actually get better after sitting for a bit, so it's perfect for meal prep. If you're bringing it to a picnic or potluck, pack the dressing separately and let everyone customize their own bowl—it's always a hit. Pro tip: Serve it chilled for the best texture and flavor.

Step-by-step instructions for cucumber tomato onion apple cider vinegar salad

Here's how to assemble this refreshing, tangy salad that balances crisp textures and bright flavors perfectly.

Start by washing all the vegetables thoroughly under cold water. For the 2 whole Persian cucumbers, cut them in half lengthwise and scoop out the seeds using a spoon—this prevents the salad from becoming watery. Then, slice them paper-thin using a mandoline or sharp knife. I like to stack the cucumber halves and slice them all at once for even cuts.

Next, halve the 3 whole medium tomatoes and squeeze out the seeds by pressing them gently over a bowl. Dice the tomato flesh into small, even pieces—about ¼-inch cubes. For the 1 whole red onion, peel it and slice off the top and bottom. Then, cut it in half and remove the white root end. Slice each half into thin rings, separating them so they don't stick together. Soak the onion slices in cold water for 5 minutes to mellow their sharpness, then drain and pat dry with a paper towel.

In a medium bowl, combine the 0.5 cup extra-virgin olive oil, 0.25 cup apple cider vinegar, 1 tablespoon raw honey, and 1 tablespoon freshly squeezed lemon juice. Whisk vigorously for 30 seconds until the honey and lemon juice dissolve completely. The mixture should look emulsified, with no visible streaks of oil.

Add the 0.5 teaspoon sea salt, 0.25 teaspoon freshly cracked black peppercorns, and continue whisking for another 15 seconds. The dressing should have a smooth, slightly thick consistency—if it looks too thin, whisk in an extra ½ teaspoon of honey to help it cling to the vegetables. Taste and adjust the balance of sweet, tangy, and salty flavors to your preference.

In a large mixing bowl, add the sliced cucumbers, diced tomatoes, and thinly sliced red onion. Sprinkle over the 0.25 cup chopped fresh dill and 0.15 cup torn fresh mint leaves, gently tossing everything together with your hands or a spatula. The herbs should be evenly distributed but still visible—this adds freshness and color to each bite.

Pour the dressing over the vegetables and toss again, making sure every piece is lightly coated. Here's the thing—don't overmix, or the cucumbers will release too much water and dilute the salad. Instead, gently fold the ingredients together until just combined. Let the salad sit at room temperature for 10 minutes to allow the flavors to meld and the dressing to penetrate the vegetables.

Transfer the salad to an airtight container or serving bowl and refrigerate for at least 30 minutes before serving. This chilling time enhances the flavors and makes the cucumbers even crunchier. When ready to serve, give the salad one final gentle toss to redistribute the dressing evenly.

This salad tastes best when served immediately after chilling, so you'll want to assemble it just before your meal. The bright green cucumbers, juicy tomatoes, and sharp onion will contrast beautifully with the tangy-sweet dressing. The herbs add a refreshing finish that makes this dish feel like a true summer celebration.

Best sauces and condiments for this dish

Classic Vinaigrette

The apple cider vinegar dressing here is the star—it’s a classic vinaigrette with a summer twist. The 1:2 ratio of vinegar to olive oil creates that perfect balance of tang and richness.

I always use raw, unfiltered apple cider vinegar like Bragg or Texas Pete because it adds depth and a subtle sweetness that complements the vegetables beautifully. If you want extra brightness, add 1 extra teaspoon of lemon juice—it cuts through any heaviness and keeps the flavors crisp. 🍏

Herb-Infused Dressing

For a more aromatic dressing, infuse the olive oil with fresh herbs before mixing. Heat ¼ cup of the olive oil in a small saucepan over low heat for 2 minutes, then remove from heat and stir in 1 tablespoon chopped fresh dill and 1 tablespoon chopped mint.

Let it steep for 10 minutes, then strain out the herbs. Use this infused oil in place of the plain olive oil in the dressing—it adds a fragrant, herbal note that elevates the entire salad. Trust me, it’s a game-changer! 🌿

Sweet and Spicy Twist

If you love a little heat, add ½ teaspoon of chili flakes or 1 finely minced jalapeño to the dressing for a sweet and spicy kick. The heat balances the sweetness of the honey and the tang of the vinegar, creating a complex flavor profile.

For extra depth, stir in ½ teaspoon of smoked paprika—it adds a subtle smokiness that pairs perfectly with the fresh vegetables. This version is especially great for serving with grilled meats or as a side to spicy dishes. 🌶️

Creamy Yogurt Dressing

For a creamier texture, blend ¼ cup plain Greek yogurt (or vegan yogurt) with the dressing ingredients. The yogurt adds a silky richness that contrasts beautifully with the crisp vegetables. I like to use full-fat Greek yogurt for the best texture, but low-fat works too if you’re watching calories.

This version is especially refreshing in hot weather and pairs well with grilled chicken or fish. Just whisk the yogurt into the dressing until smooth before tossing with the salad. 🥛

Citrusy Zest Boost

Brighten up the dressing with 1 tablespoon of freshly grated lemon or orange zest. The zest adds a burst of citrusy aroma that enhances the apple cider vinegar’s tang. For an extra layer of flavor, add 1 teaspoon of citrus juice (lemon, lime, or orange) to the dressing.

The zest and juice work together to create a vibrant, refreshing dressing that makes the salad feel even more summery. It’s a simple trick, but it makes a big difference! 🍋

Nutty Crunch Topping

While not a dressing, a sprinkle of toasted nuts adds incredible texture and flavor. Toast 2 tablespoons of chopped walnuts or pecans in a dry skillet over medium heat for 3-4 minutes until fragrant, then sprinkle them over the salad just before serving.

The nuts add a satisfying crunch that balances the softness of the cucumbers and tomatoes. For extra protein, toss in ¼ cup of toasted sunflower seeds—they’re nutty and add a delightful crunch. 🌰
