Ingredients You’ll Need

(Serves 4-6 | Prep Time: 10 minutes | Chill Time: 30 minutes)

  • 2 cucumbers, sliced (English cucumbers work best)
  • 1 large onion, thinly sliced (red or white onion)
  • 2 cups cherry tomatoes, halved
  • ¼ cup olive oil
  • ¼ cup vinegar (white or apple cider vinegar)
  • 1 teaspoon sugar
  • Salt and pepper, to taste
  • Fresh parsley, for garnish

How to Make Marinated Cucumber, Onion, and Tomato Salad

1. Prepare the Vegetables

  • Slice the cucumbers into thin rounds. If using regular cucumbers, you may want to peel them first for a smoother texture.
  • Slice the onion thinly for a mild crunch.
  • Halve the cherry tomatoes for a juicy burst of flavor.

2. Make the Dressing

In a small bowl, whisk together:
✅ Olive oil
✅ Vinegar (white vinegar for a sharper taste, apple cider for a hint of sweetness)
✅ Sugar
✅ Salt & pepper to taste

This simple dressing enhances the natural flavors of the veggies while giving them a bright, tangy kick.

3. Combine Everything

  • In a large mixing bowl, add the cucumbers, onions, and tomatoes.
  • Pour the dressing over the vegetables and toss gently until everything is evenly coated.

4. Let It Chill

Cover the bowl and refrigerate for at least 30 minutes to let the flavors meld together. For an even more flavorful salad, marinate for 2 hours or overnight.

5. Serve and Enjoy!

Just before serving, garnish with fresh parsley for a pop of color and extra freshness.


Pro Tips for the Best Salad

  • Use Seedless Cucumbers – English or Persian cucumbers are ideal since they have fewer seeds and a crunchier texture.
  • Soak Onions for a Milder Taste – If raw onions are too sharp for you, soak them in cold water for 10 minutesbefore adding them to the salad.
  • Let It Marinate Longer – The longer it sits, the better the flavors develop! If you can, let it chill for at least 2 hours.
  • Make It Creamy – Add a dollop of Greek yogurt or sour cream for a creamy variation.

Variations & Add-Ons

Want to switch things up? Here are some fun ways to customize this salad:

  • Add Avocado 🥑 – A creamy addition that pairs beautifully with the acidity of the dressing.
  • Sprinkle Feta Cheese 🧀 – A salty, tangy twist that takes this salad to another level.
  • Toss in Chickpeas 🌱 – For extra protein and texture.
  • Use Balsamic Vinegar 🍷 – Adds depth and a touch of natural sweetness.
  • Mix in Fresh Herbs 🌿 – Basil, dill, or cilantro can add a unique flavor.

FAQs

Q: Can I make this salad ahead of time?
A: Yes! This salad gets even better the longer it sits. Prepare it up to 24 hours in advance, but wait to add fresh herbs until just before serving.
