Let’s break it down step-by-step to make this sensational salad a staple in your kitchen.
Ingredients
Here’s what you’ll need to make this marinated masterpiece:
2 cups cherry or Roma tomatoes, halved or sliced
2 cups cucumber, sliced (preferably English or Persian cucumbers)
½ red onion, thinly sliced
¼ cup fresh parsley, chopped
¼ cup apple cider vinegar or red wine vinegar
2 tablespoons olive oil
1 teaspoon sugar (optional, to balance acidity)
½ teaspoon salt
¼ teaspoon freshly ground black pepper
½ teaspoon dried oregano (optional)
1 clove garlic, minced
Step-by-Step Instructions
Step 1: Prep the Veggies
Wash and dry your cucumbers and tomatoes. Slice the cucumbers into ¼-inch thick rounds. If using Roma tomatoes, slice them into wedges; if using cherry tomatoes, halve them. Thinly slice half of a red onion into half-moons.
Step 2: Make the Marinade
In a small bowl, whisk together the vinegar, olive oil, sugar (if using), salt, pepper, garlic, and oregano. This simple vinaigrette will tenderize the onion and infuse every bite with flavor.
Step 3: Combine and Toss
In a large mixing bowl, combine the tomatoes, cucumbers, and red onion. Pour the marinade over the vegetables and toss gently to coat. Add in chopped parsley and stir again.
Step 4: Let it Marinate
Cover the bowl and refrigerate for at least 30 minutes (up to 4 hours) before serving. The longer it marinates, the deeper the flavor!
Variations
• Add feta cheese – Crumbled feta adds a salty creaminess that complements the crisp veggies.
• Include bell peppers – Thinly sliced yellow or orange peppers add color and sweetness.
• Swap parsley for dill – Fresh dill brings a tangy, pickled vibe to the mix.
• Spice it up – Add a pinch of red pepper flakes or a splash of hot sauce for heat.
Cooking Note
• Use English or Persian cucumbers for less bitterness and fewer seeds.
• Roma tomatoes are meatier and less watery, perfect for marinating.
• Red onions can be soaked in cold water for 10 minutes before marinating to reduce sharpness.
Serving Suggestions
This salad is more than just a side dish—it’s an all-occasion superstar! Try these ideas:
With grilled meats – The tangy bite cuts through richness beautifully.
As a picnic essential – No mayo = great for warm-weather outings.
Topped with chickpeas – A satisfying vegan main dish.
Tucked into pita – With hummus or grilled halloumi, it’s a wrap!
Personal tip: Make a double batch—you’ll want leftovers.
Storing Tips for the Recipe
Marinated salads store incredibly well!
Refrigerate leftovers in an airtight container for up to 3 days.
Stir before serving to redistribute the marinade.
Meal prep tip: Slice veggies and mix dressing separately, then combine a few hours before serving.
Avoid freezing, as cucumbers and tomatoes lose texture when thawed.
