Ingredients
To make Classic Marinated Cucumber, Tomato, and Onion Salad, you will need:
2 large cucumbers, thinly sliced (approx. 500 g)
3 medium tomatoes, cut into wedges or chunks (approx. 400 g)
1 medium red onion, thinly sliced
¼ cup (60 ml) olive oil
3 tbsp (45 ml) red wine vinegar or apple cider vinegar
1 tsp sugar or honey
½ tsp salt
¼ tsp freshly ground black pepper
1 tsp dried oregano or 1 tbsp fresh, chopped
1–2 tbsp chopped fresh parsley or dill (optional, for garnish)
Choosing ripe, firm tomatoes and crisp cucumbers ensures the salad stays fresh and flavorful while marinating.
Pro Tips
First, slice vegetables uniformly. Consistent thickness allows even marination and prevents some pieces from becoming soggy while others remain under-flavored.
Second, let the salad sit for at least 30 minutes before serving. This allows the vinegar, olive oil, and herbs to fully infuse the cucumbers, tomatoes, and onions with balanced flavor.
Third, adjust the acidity and sweetness to your taste. A pinch of sugar or a drizzle of honey can balance the vinegar’s tang, while additional herbs can enhance aroma. For an extra refreshing texture, chill the salad before serving. Proper prep and marination make this Classic Marinated Cucumber, Tomato, and Onion Salad bright, crisp, and flavorful every time.
Instructions
Step 1: Prepare the Vegetables
Wash cucumbers, tomatoes, and parsley/dill if using. Peel cucumbers if desired. Slice cucumbers thinly and cut tomatoes into wedges or bite-sized chunks. Thinly slice the red onion. Place all vegetables in a large mixing bowl.
Step 2: Make the Marinade
In a small bowl, whisk together olive oil, vinegar, sugar, salt, black pepper, and oregano until emulsified. Taste and adjust seasoning if necessary.
Step 3: Combine Salad and Dressing
Pour the marinade over the sliced vegetables. Gently toss to coat all ingredients evenly, ensuring the cucumbers, tomatoes, and onions absorb the flavors without bruising.
Step 4: Marinate
Cover the bowl with plastic wrap or transfer to an airtight container. Refrigerate for at least 30 minutes, ideally 1–2 hours, to allow flavors to meld. Longer marination enhances taste without compromising crispness.
Step 5: Serve
Before serving, give the salad a gentle toss to redistribute the dressing. Garnish with chopped parsley or dill for color and freshness. Serve chilled or at room temperature alongside grilled dishes, sandwiches, or roasted meats.
Variations
For a Mediterranean twist, add sliced Kalamata olives and crumbled feta cheese to the salad.
For a spicy kick, incorporate thinly sliced jalapeños or red pepper flakes into the marinade.
For a low-acid alternative, replace vinegar with lemon juice and a dash of olive oil for a bright, citrusy flavor.
These variations allow you to tailor Classic Marinated Cucumber, Tomato, and Onion Salad to different tastes, cuisines, and dietary preferences.
Storage and Serving Suggestions
Store leftovers in an airtight container in the refrigerator for up to 3 days. Cucumbers may release water over time, so drain excess liquid before serving.
Serve chilled as a side to grilled chicken, fish, sandwiches, or alongside a cheese platter. This salad is also ideal for potlucks and picnic spreads, offering a refreshing and vibrant dish that balances heavier fare.
For a visually appealing presentation, layer the cucumber, tomato, and onion slices in a clear serving dish and drizzle a little extra marinade on top before serving.
