Introduction
Simple, refreshing, and bursting with summer flavor, this Classic Marinated Cucumber, Tomato, and Onion Salad is the kind of recipe that never goes out of style. It’s a crisp and colorful side dish that complements grilled meats, roasts, picnic spreads, or even a light lunch. With just a few pantry staples and fresh produce, you can whip up a salad that tastes even better the next day.
Why I Love This Recipe
This salad is proof that a handful of ingredients can go a long way. It’s got crunch from cucumbers, juicy tomatoes, and a little bite from red onions, all tossed in a simple tangy vinaigrette that mellows as it marinates. The result is a salad that’s cool, zesty, and ridiculously easy to make ahead.
It pairs perfectly with lighter meals like this no-mayo chicken salad, and also stands up next to heartier mains or picnic favorites. It’s just a total go-to in my kitchen.
Ingredients
- 2 large cucumbers, thinly sliced
- 3 medium tomatoes, cut into wedges or thick slices
- 1 medium red onion, thinly sliced
- 1/4 cup white vinegar (or apple cider vinegar)
- 3 tbsp olive oil
- 1 tbsp granulated sugar (optional, for a touch of sweetness)
- 1 tsp salt
- 1/2 tsp black pepper
- 1 tsp dried oregano (or Italian seasoning)
- 1/4 cup fresh parsley, chopped (optional)
Ingredient Swaps & Notes
- No red onion? Use shallots or sweet onion for a milder flavor.
- Vinegar options: White wine vinegar or rice vinegar can also work.
- Add-ins: Toss in olives, feta, or avocado for a Mediterranean twist.
- Make it spicy: Add a pinch of chili flakes or a dash of hot sauce to the vinaigrette.
Step-by-Step Instructions
1. Prepare the Vegetables
Slice cucumbers, tomatoes, and red onions. Place them in a large mixing bowl.
2. Make the Marinade
In a small bowl or measuring cup, whisk together:
- Vinegar
- Olive oil
- Sugar (if using)
- Salt
- Pepper
- Oregano
Taste and adjust seasoning as needed.
3. Combine and Toss
Pour the vinaigrette over the sliced vegetables. Toss thoroughly to ensure everything is evenly coated.
4. Marinate
Cover the bowl and refrigerate for at least 1 hour, ideally longer. The flavors deepen the longer they sit.
5. Serve
Before serving, toss again and garnish with fresh parsley if desired. Serve chilled or at room temperature.
Tips for Success
- Use ripe but firm tomatoes to avoid excess juice.
- Thinly slice onions to keep their bite subtle.
- Marinate overnight for best flavor (but it’s still great after just an hour).
- Serve cold for the most refreshing experience.

- Grilled chicken, fish, or steak

Storage & Leftovers
- Fridge: Store in an airtight container for up to 3 days.
- Make-ahead: Perfect to prep the night before—just toss again before serving.
- Tip: If using delicate herbs like parsley, add them just before serving to keep them fresh.
