How to Make Fresh & Tangy Marinated Cucumber, Onion, and Tomato Salad
Step 1: Prep and Chop Your Vegetables
Start by giving your cucumbers, tomatoes, and red onion some love. Peel the cucumbers if you like them extra-tender, but leaving the skin on adds wonderful color and crunch. Slice the cucumbers into thin rounds, cut the tomatoes into wedges, and slice the onion paper-thin for the best marinating power. Toss all three into a large mixing bowl, and admire the rainbow happening in your kitchen.
Step 2: Make the Tangy-Sweet Dressing
Grab a small bowl and vigorously whisk together the apple cider vinegar, olive oil, sugar, salt, black pepper, and dried oregano. You’re looking for a beautifully emulsified dressing where the sugar dissolves and the oregano is evenly distributed — you’ll know it’s ready when it smells as good as it looks!
Step 3: Marinate the Vegetables
Pour your tangy, herby dressing right over the veggies. Now, grab some tongs or a big spoon and gently toss everything together. Make sure every piece is lightly coated in the dressing to guarantee each bite of Fresh & Tangy Marinated Cucumber, Onion, and Tomato Salad bursts with balanced flavor. Cover the bowl and refrigerate for at least an hour — the hardest part is waiting!
Step 4: Add Fresh Parsley and Toss Again
Right before serving, sprinkle that vibrant chopped parsley over the marinated salad and give everything a final, gentle toss. The parsley doesn’t just add color — it brings a fresh pop that pairs perfectly with the tangy veggies.
Step 5: Serve and Enjoy!
Take the bowl out of the fridge, give it one more toss to combine any dressing that settled at the bottom, and enjoy the salad well-chilled. It’s dazzling served family-style or plated individually for that pretty, layered effect.

Garnishes
A sprinkle of flaky sea salt, a dusting of extra parsley, or a few crumbles of feta cheese can instantly elevate your Fresh & Tangy Marinated Cucumber, Onion, and Tomato Salad. For a little zing, try some freshly cracked black pepper or even a hint of grated lemon zest right before serving.
Side Dishes
This salad pairs beautifully with grilled chicken, salmon, or anything hot off the barbecue. It also brings color and freshness to savory comfort foods like roasted potatoes or crusty bread for sopping up every last drop of dressing. If you want a lighter meal, simply add chickpeas or white beans for a plant-based protein boost.
Creative Ways to Present
Try spooning your Fresh & Tangy Marinated Cucumber, Onion, and Tomato Salad into individual mason jars for a picnic, or heap it onto crostini for a zippy summer appetizer. For a family-style meal, layer the veggies artfully on a large platter and drizzle any remaining dressing over the top for an extra glossy finish.
Make Ahead and Storage
Storing Leftovers
Store any leftover Fresh & Tangy Marinated Cucumber, Onion, and Tomato Salad in an airtight container in the fridge. The flavors only grow bolder and more delicious after a good chill, making it a perfect make-ahead side. It keeps well for two to three days, but is freshest within the first 24 hours.
Freezing
Freezing is not recommended for this salad, as the fresh cucumbers and tomatoes will lose their crispness and become watery upon thawing. It’s definitely a dish best enjoyed straight from the fridge in its fresh, marinated glory.
Reheating
There’s no need to reheat Fresh & Tangy Marinated Cucumber, Onion, and Tomato Salad — it shines when served cold right from the fridge. If it’s been sitting for a day or two, give it a quick toss and maybe add a fresh sprinkle of parsley before diving in.

What’s the best way to slice the vegetables?
