Ingredients You’ll Need

One of the best things about Marinated Cucumbers, Onions, and Tomatoes is how effortlessly fresh ingredients come together. Each plays a starring role, contributing lively crunch, bright flavor, and gorgeous color to your bowl. Here’s what you’ll need:

Cucumbers: Choose firm cucumbers for fresh, crunchy texture that soaks up the marinade perfectly.
Cherry or Grape Tomatoes: These little bursts of juicy sweetness create a perfect contrast to the tangy flavors.
Red or White Onion: Thinly sliced onions add a gentle bite and a touch of sharpness without overpowering the vegetables.
Apple Cider Vinegar or Red Wine Vinegar: This is your tang factor—go for what you love or have on hand, both work wonders.
Extra Virgin Olive Oil: A splash of richness that helps bring everything together and smoothes out the acidity.
Garlic: Just one clove, minced, adds subtle depth and warmth to the marinade.
Fresh Parsley or Dill: Herbs add a pop of color and a garden-fresh finish.
Salt and Pepper: Essential for weaving all of the flavors together—season to your taste.
Red Pepper Flakes (optional): If you like a kick, this is the perfect way to add some heat without overpowering the freshness.

How to Make Marinated Cucumbers, Onions, and Tomatoes

Step 1: Prepare the Vegetables

Start by giving your veggies a good rinse—crisp, clean produce sets the foundation for this salad. Thinly slice the cucumbers (you can peel them or not, it’s up to you), halve the tomatoes for more surface area to soak in those flavors, and slice your onion super thin. A sharp knife helps to keep everything neat and even, ensuring each forkful has the perfect texture and balance.

Step 2: Whisk Together the Marinade

In a mixing bowl, combine the vinegar of your choice, extra virgin olive oil, minced garlic, a generous sprinkle of salt and pepper, and red pepper flakes if you’re feeling daring. Whisk until the marinade is well blended and aromatic—it should smell bright and inviting!

Step 3: Combine Everything

Toss the cucumbers, tomatoes, and onions together in a large bowl. Pour that delicious marinade directly over the top and toss very gently so each piece gets coated. You want every veggie to glisten with flavor, but avoid crushing the tomatoes.

Step 4: Marinate

Now comes the patience part! Cover the bowl and refrigerate for at least 30 minutes, but if you can let it sit a bit longer, the flavors only get better. Several hours (or even overnight) really lets the magic happen, as the vegetables tenderize ever-so-slightly while soaking up all those tangy, garlicky notes.

Step 5: Add Herbs and Serve

Just before you’re ready to serve, toss everything gently again, sprinkle with your favorite fresh herbs, and admire those gorgeous colors. Your Marinated Cucumbers, Onions, and Tomatoes are ready to steal the show at any meal.

Make Ahead and Storage

Storing Leftovers

If you’re lucky enough to have leftovers, just pop them into an airtight container and store in the fridge. The flavors actually get deeper by the next day, making Marinated Cucumbers, Onions, and Tomatoes even more irresistible for quick snacking or meal prep lunches.

Freezing

This salad isn’t a great candidate for freezing, since cucumbers and tomatoes become watery and soft after thawing. For best flavor and texture, enjoy freshly made or within a couple of days—though you likely won’t have leftovers for long!

Reheating

No reheating needed here. Marinated Cucumbers, Onions, and Tomatoes are always best served cold or at room temperature. Just give a quick toss before serving to distribute all that flavorful marinade evenly.

FAQs

Can I use different types of vinegar?

Do I have to peel the cucumbers?

It’s totally up to you. If you love extra crunch and a pop of green color, leave the skins on. For a softer bite, peel them first. Either way, Marinated Cucumbers, Onions, and Tomatoes will taste fantastic.

Thirty minutes is the minimum for good flavor, but if you have a few hours (or overnight), the vegetables become even more delicious as they soak up the marinade. They’ll stay crisp and flavorful for up to two days in the fridge.

Can I add other vegetables?

Definitely! Sliced bell peppers, radishes, or even thinly shaved carrots work beautifully here. Think of this recipe as a canvas—feel free to customize it with the freshest garden veggies you have on hand.
