- White distilled vinegar
- Water
- Basil
- Salt and pepper to taste
Ingredient Notes & Substitutions
Tomatoes: There is no right or wrong type of tomato. Roma, Beefsteak or on-the-vine tomatoes are great.
Cucumbers: English Cucumbers or Persian cucumbers are good, considering they have no seeds. If you don’t mind seeds, any type will do.
Onion: The onion can be red, Vidalia or white onion slices. If you’re not a fan of onion, you can also add a few dashes of onion powder to the mix of your cucumbers and tomatoes for a touch of onion without the texture.
Granulated sugar: This addition is optional but can add a tangy sweetness to this marinade. If you’re watching your sugar intake or want to reduce the carbohydrates consumed from sugar, you can opt for an alternative. Popular sugar alternatives include Swerve, stevia, and monk fruit white sugar blends.
White distilled vinegar: Swap for apple cider vinegar or lemon juice, depending on your taste and preferences! You can play with this recipe to find a suitable marinade that works for you and your whole family.

How to Make It
Step 1. Place the vegetables into a large mixing bowl and toss to combine. Remember, you can add your own variations of veggies to make this dish your own. The sky is the limit here! I recommend crunchy vegetables!

Step 2. Pour the water over the vegetables.
Step 3. In a small bowl, combine the oil, vinegar, sugar, basil, and salt and pepper to taste. Whisk to combine well and pour this over the vegetables in the bowl.

Step 4. Stir to coat the vegetables well and allow them to marinate in the fridge for at least two hours before serving. This is key. If you don’t allow this to marinade, it will become a simple cucumber and tomato salad. Which is great on its own, but the goal here is to create a marinade for these veggies. Allowing them to sit in the refrigerator for at least a couple of hours is mandatory if you want your marinade to really soak into the veggies and work!

After a couple of hours, it’s ready to enjoy!

Tips for Success
To make the best marinated cucumbers onions and tomatoes recipe, choose veggies that go together and do not skip the marinating process!
Storage & Reheating
The marinated vegetables do need to be in an airtight container and then placed into the refrigerator for up to 3 days. After that, the cucumbers may begin to soften up. I do not recommend freezing this mixture, as it will likely appear and taste soggy once it’s thawed. Instead, simply make enough so that you will not have leftovers. And, if you do have leftovers, you can consume them within 3 days!
There is no need to reheat this mixture, as it’s best served cold.
Serving Suggestions
The marinated cucumbers, onions and tomatoes can be a main dish themselves, or you can pair it up with burgers, grilled chicken or any type of meat. They’re super healthy and provide plenty of nutritional value to any meal or snack time.

FAQs
What is the dressing made of?
The dressing is made with olive oil, water, vinegar, basil and salt and pepper. It is sweet and tangy at the same time.
Can I make this in advance?
Yes, this salad can be made ahead of time and stored in the fridge until ready to serve.
