How to Make Marinated Cucumbers, Tomatoes, and Onions Recipe
Step 1: Prepare the Cucumbers
Start by washing the cucumbers thoroughly to remove any dirt and wax. Then slice them as thinly as you can to maximize their crunch and make them perfect for soaking up the marinade’s flavors.
Step 2: Slice the Tomatoes and Onions
Halve your cherry or grape tomatoes to release their natural juices into the salad, complementing the cucumbers beautifully. Next, thinly slice the onion to ensure it blends in nicely without overpowering the other veggies.
Step 3: Whisk Together the Marinade
In a mixing bowl, combine the apple cider or red wine vinegar, extra virgin olive oil, minced garlic, salt, and pepper. If you love a bit of spice, stir in the red pepper flakes here. Whisk everything together until nicely emulsified—this is your flavorful dressing.
Step 4: Combine the Vegetables and Pour the Marinade
Place the sliced cucumbers, halved tomatoes, and thin onions in a large bowl. Pour the marinade over the veggies gradually, making sure they are evenly coated for maximum flavor infusion.
Step 5: Toss and Marinate
Gently toss the salad using salad servers or your hands—just until everything is coated. Cover with plastic wrap or a lid and refrigerate for at least 30 minutes. The longer you let it rest, the more the flavors meld together, creating a sensational taste experience.
Step 6: Final Toss and Serve
Before you serve, give the salad a final toss to redistribute the marinade and freshen it up. Consider garnishing with fresh herbs like parsley or dill to add an extra pop of freshness.

Garnishes
Fresh herbs such as basil, parsley, or dill complement the natural brightness and add visual appeal. For a touch of creaminess, crumble some feta cheese on top or sprinkle toasted nuts for crunch.
Side Dishes
This marinated salad pairs wonderfully with grilled meats, roasted chicken, or fish, adding a cool contrast to warm, savory dishes. It’s also fantastic alongside crusty bread, making it a great choice for light lunches or picnics.
Creative Ways to Present
Serve it in a clear glass bowl or individual mason jars to showcase its vibrant colors. You can also spoon it atop toasted crostini for a tasty appetizer or stuff it into pita pockets for a fresh, quick meal option.
Make Ahead and Storage
Storing Leftovers
Transfer any leftovers into an airtight container and store them in the refrigerator. The salad stays fresh for up to 3 days, with the flavors developing even more as the vegetables soak in the marinade.
Freezing
This recipe isn’t suitable for freezing since cucumbers and tomatoes lose their texture and become watery when thawed. It’s best enjoyed fresh or within a few days of preparation.
Reheating
There is no need to reheat this salad. It’s intended to be served chilled or at room temperature, preserving its crisp, refreshing qualities.
FAQs
Can I use other types of vinegar?
Absolutely! While apple cider and red wine vinegar are great choices, you can experiment with white wine vinegar or even balsamic for a different flavor profile. Just remember balsamic is sweeter, so adjust seasoning accordingly.
How long should I marinate the salad?
At minimum, 30 minutes in the fridge is needed to allow the flavors to meld, but for best results, marinate for 2 hours or even overnight. The veggies will absorb even more of the delicious dressing.
Is this recipe vegan and gluten-free?
Yes, this Marinated Cucumbers, Tomatoes, and Onions Recipe is naturally vegan and gluten-free, making it a perfect option for a variety of diets without any substitutions.
Can I add other vegetables?
Definitely! Feel free to toss in sliced bell peppers, radishes, or even fresh herbs like mint. Just be mindful that adding too many watery veggies might dilute the marinade.
What can I use as a substitute for garlic?
If you’re not a fan of garlic or need an alternative, try a small amount of garlic powder or even minced shallots to keep that subtle aromatic bite.
