• 1 small red or white onion, thinly sliced: The onion brings gentle heat and beautiful contrast—it’s the secret to great depth of flavor.
• 1/4 cup apple cider vinegar or red wine vinegar: Choose your favorite—both lend brightness, but the apple cider version is a bit sweeter and fruitier.
• 2 tbsp extra virgin olive oil: Smooth, peppery, and packed with heart-healthy fats; it makes the whole salad luscious and well-blended.
• 1 clove garlic, minced: That garlicky punch infuses the marinade with unmistakable savory notes.
• 1 tbsp chopped fresh parsley or dill: These fresh herbs lift the flavors and add the perfect finish—dill gives it old-school deli vibes, parsley keeps it super fresh.
• Salt and pepper to taste: Don’t be shy—seasoning brings all the flavors to life!
• 1/2 tsp red pepper flakes (optional): Add a gentle kick of heat, if you like a bit of spice.

How to Make Marinated Cucumbers, Onions, and Tomatoes

Step 1: Prep the Veggies

Kick things off by giving your cucumbers and tomatoes a gentle rinse. Thinly slice the cucumbers for instant crunch, halve the cherry or grape tomatoes for juicy bursts of flavor, and slice the onion as thin as possible (a sharp knife or mandoline makes this easy!). The beauty here is in the textures—each ingredient cut just right so every forkful is fresh and balanced.

Step 2: Whisk Together the Marinade

In a mixing bowl, combine your vinegar of choice, extra virgin olive oil, minced garlic, a generous pinch of salt and cracked black pepper, and those red pepper flakes if you’re adding them. Whisk until the oil and vinegar come together in a glorious, glossy vinaigrette. This dressing is the flavor backbone—tangy, garlicky, with just a hint of heat!

Step 3: Bring It All Together

Place the cucumbers, tomatoes, and onions into a large bowl. Pour your zippy marinade over the veggies and toss gently—but thoroughly—so every single slice gets coated. At this stage, the aroma is already irresistible and those bright colors will have you reaching for a fork!

Step 4: Let the Magic Happen (Marinate!)

Cover the bowl and pop it into the refrigerator. Give it at least 30 minutes so the flavors can mingle, but if you wait a few hours or even overnight, Marinated Cucumbers, Onions, and Tomatoes become even more delicious as everything melds. Before serving, toss again to redistribute all those tasty juices.

Step 5: Finish and Serve

Just before serving, scatter chopped fresh parsley or dill on top for a green, herbaceous burst. The final flourish makes the dish so inviting—now simply arrange on a platter or serve in a big bowl, and watch it disappear!

Make Ahead and Storage

Storing Leftovers

Transfer any extra Marinated Cucumbers, Onions, and Tomatoes to an airtight container and keep them in the refrigerator. They easily last up to 3 days, and you’ll notice the flavors deepen over time as the veggies continue to absorb the savory vinaigrette. The veggies may soften slightly but remain deliciously tangy and satisfying.

Freezing

While technically you can freeze this salad, it’s not recommended—cucumbers and tomatoes tend to lose their crunch and release extra liquid when thawed. You’ll get the very best taste and texture by enjoying Marinated Cucumbers, Onions, and Tomatoes fresh or simply well-chilled from the fridge.

Reheating

Good news: no reheating required! This dish is meant to be served chilled or at room temperature, making it the ultimate low-fuss, make-ahead side. If the salad’s been in the fridge for a couple of days, just give it a quick toss to redistribute the dressing before digging in.

FAQs

Can I use different types of cucumbers or tomatoes?

Absolutely! English or Persian cucumbers offer less seeds and thin skin, so no peeling needed, while Roma, heirloom, or even big slicing tomatoes (just cut into chunks) all work well for Marinated Cucumbers, Onions, and Tomatoes. Variety brings unique textures and flavors.

How long should I marinate the vegetables?

As little as 30 minutes gives you a vibrant, crunchy salad, but for deeper flavor, let it marinate several hours or overnight. It’s actually one of those recipes that tastes even better the next day!

Can I make this recipe oil-free?

You can skip the olive oil, but the salad will be a bit sharper and less silky. If you’re omitting oil, try adding a spoonful of water or a splash of lemon juice to mellow out the vinaigrette for Marinated Cucumbers, Onions, and Tomatoes.

Is this dish suitable for vegan, gluten-free, or paleo diets?

Definitely! Every ingredient in Marinated Cucumbers, Onions, and Tomatoes is plant-based and naturally gluten-free. Just double-check that your vinegar is malt-free if you’re extra sensitive, but otherwise, it fits lots of special diets.

What should I do if the salad is too tangy for my tastes?

Try stirring in a pinch of sugar or a drizzle of honey to balance the acidity, or add a little more olive oil for richness. The flavors are flexible, so adjust the marinade until you find your perfect sweet-tart balance.
