How to Make the BEST Cucumber Salad Recipe

Prep the Cucumber and Red Onion – Use a mandoline or a sharp knife and chopping board to thinly slice the cucumber and red onion.
Draw the Liquid from the Cucumber – Add the cucumber slices to a colander and sprinkle with 1/2 of the garlic salt. Toss to coat then let sit for 15-20 minutes to draw out the water content.
Make the Vinegar Dressing – Whisk together the vinegar, sugar and remaining garlic salt. Add 1 Tbsp coarsely chopped fresh dill. (You can eyeball the amount) Toss to coat then set aside to marinate while the cucumber drains.
Combine – Drain the cucumbers then add to the onion mixture, stir to combine.
Garnish – Serve immediately garnished with freshly ground black pepper and additional dill.

Kitchen Tools You’ll Need

Mandolin or sharp knife and chopping board for slicing the cucumber and onion.
Measuring cup and spoons for accurate measurements of the vinegar and seasonings.
Colander for draining the juices from cucumbers after slicing.
Medium bowl for “pickling” the red onion.

Recipe Variations and Substitutions

Cucumbers: English cucumbers have thinner skin and there’s no need to remove the seeds, hence the reason I leave the peeling intact. You could also use garden cucumbers or Persian cucumbers, which are the cucumbers most commonly found in the produce department of most grocery stores.
Onion: You could use thinly sliced green onions, white onion or yellow onion in place of red onions.
Vinegar: You can use red wine vinegar, white wine vinegar, distilled white vinegar or white balsamic vinegar in place of apple cider vinegar.
Sugar: You can omit the granulated sugar and use honey, agave syrup or an artificial sweetener i.e. Truvia or similar that you enjoy.
Spice: You could use crushed red pepper flakes for a hint of spice.
Tomatoes: You could add 1/2 cup diced tomato or halved cherry tomatoes to cucumber salad.
Fresh Herbs: You could use fresh chives, tarragon, fresh basil or parsley in place of dill.

Storage and Leftovers

Make-Ahead Tip: You can make this cucumber salad one day in advance.
Storage: Store Cucumber Onion Salad in an airtight container chilled in the refrigerator for up to 3 days.
Freezing: I don’t recommend freezing cucumber salad as the fresh cucumbers will break down when thawing.
