Crunchy, Tangy Cucumber Creation

Flavor: Sweet cukes and sharp onions perfectly contrast the tangy vinaigrette.
Prep note: Slice cucumbers and onions thinly for best texture, and let the salad sit for at least an hour to develop flavor.
Budget tip: Use regular cucumbers and white vinegar, both are cost-effective ingredients.
Time-Saving Tip: Prepare and refrigerate ahead of time for a quick, easy snack or side dish.
Serving suggestions: Serve as a side dish to grilled meats or as a light lunch keto bread or crackers. Or turn it into a main by adding bay shrimp, shredded chicken, diced ham, or bacon bits.

Easy Salad Ingredients

Cucumber: Fresh cucumbers are firm and taste slightly sweet. English cucumbers are longer and thinner than field cucumbers and are preferred for this recipe since the seeds and peels aren’t as tough. You can use either or a combination of both.

Onion: White onions are sweeter than other varieties but you can use Vidalia, yellow, or red onions. Be sure to cut (or dice) them small enough so as not to overpower the other ingredients.

Vinaigrette: I prefer rice or white wine vinegar for salads, as they are less tart than red wine or regular white vinegar. Use any variety of oil or vinegar in this recipe, just keep the amounts the same. You can still use red or apple cider vinegar in a pinch, although they might dull the color of the salad. For a creamy dressing, whisk in some Dijon mustard.

Variations: For a pop of color, add some halved cherry or grape tomatoes, chopped sundried tomatoes, or diced avocados. Finely chopped black olives or jalapenos will also add color and zesty flavor.

Holly’s Recipe Tips & Tricks

This recipe works best when the cucumber slices are thoroughly patted dry. This allows the dressing and seasonings to cling properly.
Use a mandoline to slice the white onions uber-thin so their flavor doesn’t overpower the salad.
This recipe tastes best when it’s extra chilled, so you can make it up to a day ahead and keep it covered until ready to enjoy. Double the dressing and use as a marinade or on other salads.
Keep leftover cucumber & onion salad in a covered container for up to 5 days. Stir before serving.
