This simple Cucumber Onion Salad is a delicious combination of cool cucumber, sweet onion, and tangy marinade that will have you eating most the dish before it ever makes it to the table. 

Cucumber Onion Salad is a total classic, and one of my favorite salad recipes during the summer for BBQ’s and potlucks. It’s pretty much on constant rotation with tomato cucumber salad, potato salad, and pasta salad.

Ingredients:

  • Cucumbers: I love mini cucumbers or English cucumbers because they are long, thin, and seedless and there is no need to peel them.  Regular, grocery store cucumbers have a thicker, tougher, and waxier skin that you may want to peel first.  However, any cucumbers will work well.
  • Onion: I recommend using a sweet onion or red onion so that the flavor doesn’t overwhelm the cucumbers.
  • Vinegar: I used a combination of white vinegar and red vinegar, but you can use what you have on hand including cider vinegar, or rice wine vinegar.
  • Salt and pepper
  • Sugar
