Ingredients You’ll Need

½ cup + 2 tablespoons granulated sugar: This adds a touch of sweetness that balances the vinegar’s tang. If you prefer, honey or agave syrup could work as alternatives.
2 teaspoons kosher salt: Essential for enhancing the flavors of your veggies while drawing out moisture from the cucumbers and onions.
½ teaspoon coarse ground black pepper: Adds an aromatic spiciness that ties the flavors together.
4 tablespoons water: Helps dissolve the sugar and salt in the marinade, ensuring even distribution.
½ cup white vinegar: The star of the dressing, providing that signature tang. Apple cider vinegar can also be used for a milder flavor.
1 large English cucumber (¼ inch thick slices): Crisp and refreshing; English cucumbers have a thin skin and fewer seeds. You could substitute with an ordinary cucumber if necessary, just peel it first.
½ large yellow onion, sliced thin: This brings a robust flavor that complements the cucumbers. Red onions can be a colorful alternative if you prefer.
2 cloves garlic, smashed: A subtle but key addition that enhances the overall taste profile.
1 teaspoon finely chopped fresh dill: This herb brings a fresh, aromatic hint to the salad, elevating it further. If fresh dill isn’t available, dried dill can be used in a pinch.

How to Make Cucumber and Onion Salad

Prepare the Marinade: In a deep container with a tight-fitting lid, combine ½ cup + 2 tablespoons granulated sugar, 2 teaspoons kosher salt, ½ teaspoon coarse ground black pepper, 4 tablespoons water, and ½ cup white vinegar. Stir until the sugar is mostly dissolved, which should take just a minute or two.
Combine Vegetables and Marinate: Next, add 1 large English cucumber, sliced into ¼ inch thick slices, ½ large yellow onion, sliced thinly, and 2 cloves of smashed garlic to the marinade. Gently stir and shimmy until all the ingredients are submerged in the liquid, allowing the flavors to mingle beautifully.
Let It Sit: Cover the container tightly. Ideally, let this refreshing salad sit at room temperature for 2 hours. This waiting period is crucial as it allows the vegetables to marinate, enhancing their flavors.
Serve: Once the time is up, drain any excess liquid, garnish with 1 teaspoon of finely chopped fresh dill, and serve. It pairs beautifully with rich or heavy dishes, making every bite more enjoyable.

Storing & Reheating

Store any leftovers of Cucumber and Onion Salad in an airtight container in the refrigerator for up to 3 days. If you want to keep it fresh longer, you can freeze it—but note that the texture might change slightly after thawing and may become a bit mushy. Reheat gently in a skillet over low heat just until warmed through, or enjoy it cold. For a jolt of freshness, sprinkle some additional dill just before serving!

Chef’s Helpful Tips

Avoid using overly ripe cucumbers; they can be watery and less crisp. Look for firm cucumbers with smooth skin.
If your onions are too strong, soak them in cold water for about 10 minutes before adding them to the salad; this can mellow their flavor.
For extra crunch, consider adding sliced radishes or bell peppers.
To make ahead, prepare this salad a day in advance. Just hold off on adding the dill until serving time to keep its flavor bright.

Cucumber and Onion Salad is a breeze to prepare and is sure to become a crowd favorite. The balance of flavors creates a dish that elevates any meal, and the best part is how it can be customized. Try adding your favorite herbs or swap out ingredients based on what you have on hand. This is your chance to get creative while keeping things fresh.
