Everything You Need for Marinated Cucumbers, Onions and Tomatoes
- 2 medium cucumbers, thinly sliced
- 1 medium red onion, thinly sliced
- 2 medium tomatoes, diced
- 1/4 cup apple cider vinegar
- 1/4 cup olive oil
- 2 tablespoons sugar
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon dried oregano
- 1 tablespoon fresh parsley, chopped
The apple cider vinegar is the heart of the dressing, delivering a tangy punch that binds everything together. Meanwhile, the dried oregano adds a warm, earthy depth, perfectly balancing the acidity of the vinegar and the sweetness of sugar.
How To Make Marinated Cucumbers, Onions and Tomatoes Step by Step
- In a large mixing bowl, combine the sliced cucumbers, red onion, and diced tomatoes. Toss gently to evenly distribute the vegetables.
- In a separate small bowl, whisk together the apple cider vinegar, olive oil, sugar, salt, black pepper, and dried oregano until fully emulsified.
- Pour the prepared vinaigrette over the vegetable mixture, ensuring every piece is coated evenly.
- Cover the bowl with plastic wrap and refrigerate for at least 1 hour to allow the flavors to meld.

- Before serving, sprinkle the salad with fresh parsley and give it a light toss to refresh the dressing.
Common Questions About This Recipe
- Can I make this salad ahead of time? Yes! In fact, it’s best to let it marinate for at least an hour. Making it a day in advance enhances the flavors even more.
- How should I store leftovers? Keep the salad in an airtight container in the refrigerator for up to 3 days. Stir it before serving to redistribute the marinade.
- Can I use a different type of onion? Absolutely. Sweet onions or white onions also work well, though red onion provides a slightly sharper flavor and vibrant color.
Easy Ingredient Swaps and Substitutions
- If you don’t have apple cider vinegar, substitute with white wine vinegar or rice vinegar. Both provide a gentle acidity that complements the vegetables.
- Swap dried oregano for fresh oregano for a bolder, herbaceous note. Use about 1 tablespoon of fresh oregano leaves in place of the teaspoon of dried.
- Out of tomatoes? Try halved cherry tomatoes for a sweeter bite and a fun presentation.
Avoid These Common Mistakes
- Skipping the chilling step: The marination time is crucial for blending the flavors. Don’t rush this step or the salad may taste underwhelming.
- Overdressing the salad: While the vinaigrette is delicious, too much can overpower the fresh vegetables. Stick to the measurements in the recipe for balance.
- Using overripe vegetables: Crisp cucumbers and firm tomatoes are key to maintaining the salad’s texture. Avoid produce that is too soft or mushy.
Expert Tips for Perfect Results
- Use a mandoline for slicing: Uniform slices not only look beautiful but also ensure even absorption of the marinade.
- Marinate in glass or stainless steel bowls: These materials don’t react with the vinegar, preserving the freshness of the dressing.
- Double the batch: This salad stores well and makes an excellent meal prep option for busy weeks.
- Add extra herbs: A sprinkle of dill or basil can elevate the flavors, especially if serving with Mediterranean-inspired main courses.
