Old-Fashioned Cucumber Salad (with Vinegar & Onions)

This old-fashioned cucumber salad recipe is the perfect side dish for all of your favorite summer meals! Made with thin slices of fresh cucumbers, slices of sweet onions, white vinegar, water, fresh dill, salt, and a small amount of sugar this quick-pickled cucumber salad is the crunchy and fresh side dish your summer needs.

This simple recipe is a family summertime favorite that you’ll find almost weekly in our house when the weather is warm! My grandma and my mom have made variations on this easy cucumber salad recipe since I was a kid. Like our Mediterranean cucumber salad with cherry tomatoes and feta cheese, this easy cucumber onion salad pairs wonderfully with all your favorite grilled foods, like homemade turkey burgers, beer brats, pork chops, or even your favorite hot dogs.  

And since this refreshing cucumber salad is vinegar based (no creamy dressing here), it’s a great light and fresh addition to your summer cookouts! Served alongside a protein, a nice scoop of pasta salad, and some chips… that’s summer on a plate!

Ingredients Needed

English Cucumber. I find English cucumbers to be the best cucumbers for this salad. They have a thinner skin, fewer seeds (no deseeding needed!), and a slightly sweeter taste than regular cucumbers. 

White Onion or Yellow Onion. We’re looking for a mild, sweet onion for this recipe. White onions are more mild than yellow onions. White onions are often recommended for raw preparations (like this kind of salad, pico de galo, etc.). However, you can also find sweeter yellow onions like the Vidalia onion or Maui onion varieties. In general though, white and yellow onions can be substituted for one another in a pinch.

White Vinegar. White vinegar is the most common kind of vinegar that you can find in any grocery store. White vinegar is a highly acidic cooking liquid that’s been used for centuries to flavor, pickle and preserve all kinds of ingredients. It’s known for it’s tangy, sour taste. 

Water. We use an equal amount of water to vinegar in this recipe to tamp down and balance the acidity from the vinegar.

Granulated Sugar. Adding a little bit of sugar to these vinegar cucumbers is another way to balance the dish, taking the edge off of the vinegar base.

Fresh Dill, Salt, and (optionally) Black Pepper. Used to flavor and season our quick-pickled cucumbers and onions.

Recipe Variations and Substitutions

• Skip the onion. Don’t love raw onion? No worries, just leave it out!
• Use a regular cucumber. If you have fresh garden cucumbers that need to be used, this is a great recipe for them! I would recommend slicing them in half the long way and de-seeding them for this recipe if making this substitution. 
• Try different fresh herbs. You can add additional herbs to this recipe, try different herbs, or create your own mix! Try fresh parsley, fresh basil, or chives.
• Use apple cider vinegar instead of white vinegar. If preferred, you can use apple cider vinegar for a more mild, sweeter salad dressing.

Step-by-Step Instructions

Step 1: Slice the cucumber into thin rounds, and chop onion into thin strips, and place into a large bowl. 

Step 2: Add sugar, salt, and pepper (if using).

Step 3: Pour vinegar and water over the other ingredients.

Step 4: Add sprigs of fresh dill, and stir to combine.

Step 5: Allow to pickle for at least 10 minutes (can sit overnight too!), stirring a few times to ensure the vinegar mixtures has coated all the cucumbers and onions.

Step 6: Serve with a slotted spoon to allow excess water to drain before plating.

Storage

This salad is best when eaten within 1-2 days of making. Store leftovers in an airtight container (or in your bowl covered in plastic wrap) in the fridge for up to 3 days.

Recipe FAQs

Should I Peel Cucumber for Salad?

There is no need to peel a cucumber for salad (just be sure to rinse them well). Leaving the peel on helps to maximize the nutrient content of the vegetable, helping you add fiber, vitamins, and minerals to your diet. 

What is the Difference Between English Cucumber and Regular Cucumber?

An English cucumber (also known as seedless cucumbers) has a thinner skin, fewer and smaller seeds, and a slightly sweeter taste than regular cucumbers. They are also long and straight in shape. Standard cucumbers are generally shorter, have a thick and dark skin, and very large seeds.
