Step-By-Step Cooking Instructions

Making this cucumber tomato salad is super straightforward. Just follow these easy steps:

1. Prep the vegetables
Start by washing your cucumber and tomatoes. Slice the cucumber into thin rounds—if you’re using an English cucumber, there’s no need to peel it. Halve the grape tomatoes and slice the red onion as thin as possible for the best texture.

2. Combine the veggies
In a large mixing bowl, add the sliced cucumber, halved tomatoes, and red onion. Sprinkle in the chopped parsley.

3. Make the vinaigrette
In a small bowl or jar, whisk together the olive oil, red wine vinegar, sugar, dried basil, salt, and black pepper. Stir until the sugar dissolves and everything is well combined.

4. Toss everything together
Pour the vinaigrette over the vegetables. Using salad tongs or clean hands, gently toss until all the vegetables are evenly coated with the dressing.

5. Let it marinate
If you have the time, cover the bowl and refrigerate the salad for at least 30 minutes before serving. This allows the flavors to meld and intensify, resulting in an even more delicious dish.

6. Taste and adjust
Before serving, give the salad a quick stir and taste. Adjust salt, pepper, or vinegar if needed.

This salad is best served chilled, and the flavor continues to develop the longer it sits in the fridge. However, it’s just as good when served fresh and crisp.

How to Serve

This salad shines in its versatility. Here are a few delicious ways to serve it:

• As a light side with grilled chicken, beef kebabs, or fish
• Tucked into a wrap with hummus or falafel

Storage, Freezing & Reheating Instructions

This salad is best enjoyed fresh or within a few days, but here’s how to store it properly:

Refrigeration:
Store leftovers in an airtight container in the refrigerator for up to 3–4 days. The veggies will soften slightly over time, but the flavor remains bright and delicious.

Freezing:
Freezing is not recommended for this salad. The water content in cucumbers and tomatoes causes them to become mushy when thawed.

Reheating:
There’s no need to reheat this dish—serve it straight from the fridge or let it sit at room temperature for 10–15 minutes before serving.

Common Mistakes to Avoid

Avoid these common pitfalls to make sure your salad turns out perfect every time:

• Using watery cucumbers: Opt for English or Persian cucumbers, which are less watery and have fewer seeds.
• Overdressing the salad: Start with a small amount of dressing and add more as needed to avoid soggy vegetables.
• Not slicing onions thin enough: Thick slices can be too pungent; aim for paper-thin to blend seamlessly.
• Skipping the marination time: While not essential, letting the salad sit for 30 minutes enhances flavor and texture.
• Over-salting too early: Salt draws out moisture from the vegetables. If making ahead, wait to add salt just before serving.

Pro Tips

• Soak onions in cold water: If raw red onion is too sharp for your taste, soak the slices in cold water for 10 minutes to mellow them out.
• Make it ahead: This salad gets better with time. Prepare it a few hours in advance for the best flavor.
• Switch up the herbs: Try fresh dill, mint, or basil to change the flavor profile.
• Add a crunch: Top with toasted almonds, sunflower seeds, or croutons just before serving for added texture.
• Use a mandoline: For uniform and super-thin cucumber slices, a mandoline slicer is a game changer.

Frequently Asked Questions (FAQs)

Can I use cherry tomatoes instead of grape tomatoes?
Yes, cherry tomatoes work just as well. Slice them in halves or quarters, depending on size.

Can I use a regular cucumber instead of English cucumber?
You can, but regular cucumbers may have more seeds and water. If using them, consider peeling and seeding first.

Is it okay to skip the sugar in the dressing?
Absolutely. The sugar balances the acidity, but if you prefer, you can omit it or substitute it with honey or maple syrup.

What herbs work best in this salad?
Parsley is classic, but basil, dill, or cilantro are all great options. Mix and match to find your favorite combo.

How far in advance can I make this salad?
You can prepare it up to 24 hours in advance. Just store it covered in the fridge and give it a quick stir before serving.

Can I add protein to make it a meal?

Is this salad vegan?
Yes, the base recipe is naturally vegan and dairy-free. Just skip any cheese add-ins if you’re keeping it vegan.

Can I add feta cheese?
Definitely. Crumbled feta adds a salty, creamy element that pairs wonderfully with the fresh vegetables.

Why does my salad get watery?
Cucumbers and tomatoes release water over time, especially with salt. Serve the salad soon after dressing or drain off excess liquid before serving.

Yes, this recipe scales up easily for potlucks, picnics, or meal prep.
