This cucumber salad is quick and easy to make, coming together in about 10-15 minutes. It is perfect for serving right away or storing in the refrigerator to marinate in the simple dressing, making it even more delicious. Here’s how you’ll make it.

Ingredients

Be sure to see the recipe card below for the full listing of ingredients, instructions, notes, and estimated nutritional information.

Cucumbers – Use whatever type of fresh cucumbers you wish. I find that crisp ones from our garden or farm stand work well. If you prefer fewer seeds, you can use an English cucumber instead.

Onions – Use a sweet onion for this recipe, such as a Vidalia onion or a red onion. After peeling it, you’ll slice the onion into long, thin strips. You can omit the onion if you wish.

Simple Dressing – Use apple cider vinegar (or distilled vinegar) and Stone House Seasoning.

Step-by-Step Instructions

1. Prep the cucumbers and onion. Start by peeling and slicing the cucumber and the onion according to recipe instructions.
2. Make the dressing. Next, you’ll mix the vinegar and Stone House seasoning to make the dressing by adding them to a large liquid measuring cup or bowl. Whisk well and pour the dressing over the salad.
3. Refrigerate / Serve. Cover and place the salad in the refrigerator for at least one hour before serving. You can also leave it refrigerated overnight to allow the cucumbers to marinate in the dressing even more.

Recipe Variations

I’ve seen so many versions of this iconic Cucumber Onion Salad. Here are some variations.

Adjust the vinegar – Some adjust the vinegar in the dressing to suit their taste.

Add tomatoes – Add in diced tomatoes (Cucumber, Tomato and Onion Salad)

Use small pickling cucumbers – Use these small, very crisp cucumbers instead of English or another type.

Add a little sugar – Sugar is listed as an optional ingredient if you wish to give the salad a sweet and tangy taste.

Storage Tips

Keep leftover salad in an airtight container in the refrigerator for up to 3 days. If you mix the dressing separately, store it in an airtight jar in the fridge for up to 5 days.
