How to Make Cucumber Salad {Quick Overview}

This is a quick overview of how to make this low carb cucumber salad. For exact measurements and detailed directions, see the recipe card at the end of the post.

Start by preparing the vegetables and herbs. Thinly slice the English cucumbers. There is no need to peel them because English cucumber skins are thin, tender, and mild in flavor.

Next, thinly slice the red onion. If you prefer a milder onion bite or smaller pieces, you can dice the onion instead. Chop the fresh dill, then add the cucumbers, onion, and dill to a large mixing bowl.

In a separate small bowl, make the dressing by whisking together the red wine vinegar, salt, pepper, and optional sugar substitute. The vinegar gives this salad its bright, zesty flavor, while the optional sweetener softens the acidity without adding sugar.

Toss gently until all of the vegetables are evenly coated in the dressing.

For the best flavor, loosely cover the bowl and refrigerate the salad for at least 30 minutes before serving. This short chilling time helps the cucumbers stay crisp while allowing the dressing, onion, and dill to blend together.

Serve this easy cucumber onion salad cold and enjoy it as a refreshing side with grilled foods, picnic dishes, or simple low carb meals.

Properly stored, this salad can last for 2 to 3 days in the fridge. The cucumbers may release some liquid as they sit, so give the salad a gentle toss before serving leftovers.
