  • Cucumbers (any vareity will work, we like English, and Persian)
  • Onions (red or all purpose)
  • Salt
  • Sugar (I use coconut sugar, but refined sugar works as does honey)
  • Dill (fresh is best and optional)
  • Apple cider vinegar (or any variety of vinegar)

How to make old-fashioned cucumber salad

Step 1: Prepare the ingredients. Wipe the cucumbers clean with a damp cloth or run them under cold water and pat them dry. Then use a sharp knife, food processor, slicing blade or mandoline slicer to slice the cucumber and onion as thin as possible. Measure the salt, sugar, and vinegar, and chop the fresh dill with a sharp knife.

STEP 2: Place the sliced cucumbers into a medium-sized bowl with the onion slices.

STEP 3: Stir in the salt and sugar, and allow the cucumbers to sit at room temperature for one hour.

STEP 4: At this point, the cucumbers will have released water into the bowl. You do not need to drain the cucumbers. If the amount of water seems sparse, add a tablespoon of water.

STEP 5: Stir in the vinegar and chopped dill. Adjust the flavor with more water for a less vinegary taste.

Tips for making the best cucumber and onion salad:

  • For the best results, slice the cucumbers as thinly as possible. A mandoline slicer or a very sharp knife.
  • The balance of flavor really depends on your taste. The cucumbers usually provide enough water to mix with the vinegar. Taste before serving and adjust to your taste, add more water to reduce the vinegar flavor or more vinegar for a less water flavor.
  • Experiment with different vinegars each one will impart its own flavor.

This cucumber and onion salad is just the starting point. Once you’ve got the basics down, you can switch things up based on what’s in your fridge or what you are craving.

Switch up the vinegar: Try apple cider vinegar for a more mellow flavor, red wine vinegar for depth and rice vinegar for something softer.

Try different onions: Red onions add a pretty pop of color and a milder bite. Sweet onions or thinly sliced shallots work great too.

Add fresh herbs: Dill is classic, but parsley, chives, or mint can add a fresh twist.

Make it spicy: Toss in a pinch of crushed red pepper flakes or a few thin slices of jalapeno for some heat.

Go crunchy: A handful of sunflower seeds or sesame seeds for a little more texture.

Recipe FAQs

Why are the cucumbers soaked in salt and sugar?

The cucumbers are soaked in salt and sugar brine to draw the water out of the cucumber slices and add flavor. The water also dilutes the vinegar taste; more water can be added if the vinegar is too strong.

Do I have to peel the cucumbers before making this salad?

It’s okay not to peel cucumbers when the skin is thin, as it is on baby, Persian, or English cucumbers. If the skin is thick and tastes bitter, it’s best to peel the cucumbers.

Should the cucumbers be drained before adding the vinegar?

No! Do not drain the cucumbers before adding the vinegar. The water from the cucumbers will dilute the vinegar, and it can be adjusted by adding more water and sugar to taste.

    I’ve made this recipe for my country folks that have passed on many times. I have a question for you. After slicing the cucumbers & setting aside to allow water release, do you rinse them or pat dry or anything? Thank you

    1. Thanks for your comment, Debbie. I don’t pat the cucumbers dry, I use the liquid from the cucumbers and then add vinegar. I will adjust the taste with water at the  if they are too salty or the vinegar is too much.
