Cucumbers: Choose crisp, firm cucumbers for the ultimate crunch—they soak up the marinade beautifully!
Cherry or Grape Tomatoes: These tiny tomatoes bring bursts of sweetness and juiciness, and their size makes for easy, bite-sized salads.
Red or White Onion: Sliced thin, onions add just the right kiss of sharpness to balance the other flavors.
Apple Cider Vinegar or Red Wine Vinegar: The vinegar adds bright acidity that really perks everything up; either option works, so use your favorite.
Extra Virgin Olive Oil: Just a drizzle gives the marinade body and richness, rounding out the tartness of the vinegar.
Garlic: Just a hint of minced garlic brings incomparable depth and aroma.
Fresh Parsley or Dill: Herbs make everything pop! Dill lends an old-fashioned, pickle-like note, while parsley adds grassy freshness.
Salt and Pepper: Essential! Don’t skimp—these basics make all the other flavors shine.
Red Pepper Flakes (optional): If you like a little extra zing, these add the perfect touch of heat.

How to Make Marinated Cucumbers, Onions, and Tomatoes

Step 1: Prep the Vegetables

Wash your cucumbers and tomatoes thoroughly—don’t skip this step, because you want everything to be super fresh. Go ahead and thinly slice the cucumbers (peel if you prefer), halve your cherry or grape tomatoes, and slice the onion as thinly as you can for the best texture that melds perfectly into the salad.

Step 2: Whisk the Marinade

In a mixing bowl, combine the vinegar of your choice, extra virgin olive oil, minced garlic, salt, and freshly ground pepper. If you want to turn up the flavor, toss in those red pepper flakes! Whisk everything together until well combined—the aromas will have your mouth watering already.

Step 3: Toss Everything Together

Place the prepped cucumbers, tomatoes, and onions into a large bowl. Pour the marinade over the veggies and use a big spoon or your hands (go ahead, it’s fun!) to toss everything until the vegetables are glossy and evenly coated. Don’t rush—making sure every slice gets a touch of that tangy dressing is worth it.

Step 4: Marinate

Cover the bowl with plastic wrap or a lid and slide it into the refrigerator for at least 30 minutes. If you can wait a few hours or even overnight, do it! The flavors will blend together and create something truly special. This patience step transforms the veggies into the magic that is Marinated Cucumbers, Onions, and Tomatoes.

Step 5: Serve and Garnish

When you’re ready to eat, give everything another gentle toss. Sprinkle with that fresh parsley or dill for a gorgeous, fragrant finish, and serve your Marinated Cucumbers, Onions, and Tomatoes chilled, alongside your favorite main—or all on their own for a refreshing snack.
