Ingredients for Marinated Cucumbers, Onions, and Tomatoes
The beauty of this dish is its simplicity. You don’t need fancy ingredients—just a few fresh vegetables and pantry staples.
Vegetables:
- 2 large cucumbers (or 3-4 small Persian cucumbers), thinly sliced
- 3 large tomatoes, chopped into bite-sized pieces
- 1 medium red onion, thinly sliced
For the Marinade:
- ½ cup apple cider vinegar (or white vinegar for a sharper taste)
- ¼ cup olive oil (or vegetable oil for a milder flavor)
- 1 tablespoon sugar (adjust based on taste preference)
- 1 teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon garlic powder (or 1 minced garlic clove for a stronger flavor)
- ½ teaspoon dried oregano (or Italian seasoning)
- ½ teaspoon dried basil
- ¼ teaspoon crushed red pepper flakes (optional, for a slight kick)
Optional Additions:
- Fresh herbs (like parsley, dill, or basil) for extra flavor
- Feta cheese crumbles for a creamy, tangy touch
- Sliced avocado for added creaminess
- Cherry tomatoes instead of regular tomatoes for a different texture
- Balsamic vinegar instead of apple cider vinegar for a deeper, slightly sweet flavor
Step-by-Step Instructions
Step 1: Prepare the Vegetables
- Wash and dry all the vegetables to ensure they are clean and free of dirt or pesticides.
- Slice the cucumbers into thin rounds. If you’re using regular cucumbers, you may want to peel them first and remove the seeds for a smoother texture. If using English or Persian cucumbers, leave the skin on for extra crunch.
- Chop the tomatoes into bite-sized pieces. If using cherry or grape tomatoes, simply slice them in half.
- Thinly slice the red onion into half-moon strips. This will help distribute the onion flavor without overpowering the dish.
Step 2: Make the Marinade
- In a large mixing bowl, whisk together vinegar, olive oil, sugar, salt, pepper, garlic powder, oregano, basil, and red pepper flakes.
- Stir until the sugar dissolves completely, ensuring a well-balanced marinade.
- Taste and adjust the seasoning if needed. You can add more sugar for sweetness, more vinegar for tanginess, or more salt for enhanced flavor.
Step 3: Combine Everything
- Add the cucumbers, tomatoes, and onions to the bowl with the marinade.
- Toss everything together, ensuring the vegetables are evenly coated in the dressing.
- Cover the bowl and let it marinate in the refrigerator for at least 30 minutes. For the best flavor, allow it to sit for 2-4 hours or even overnight.
Step 4: Serve and Enjoy
- Once marinated, give the salad a quick stir to redistribute the dressing.
- Serve chilled or at room temperature as a side dish, salad, or even a topping for grilled meats or sandwiches.
- Garnish with fresh herbs, extra black pepper, or crumbled feta cheese for added flavor.
Tips for the Best Marinated Cucumber, Onion, and Tomato Salad
