  • 1 medium red onion, thinly sliced
  • ½ cup white wine vinegar
  • 1 tablespoon granulated sugar
  • 1 teaspoon coarse salt


  • Using a knife, remove the top and bottom of the onion and peel any excess off to reveal the skin of the onion.
  • Thinly slice the red onion into round strips. If you have a mandoline, you can use it instead. Place the red onion slices in a medium-sized wide-mouth jar with a lid.
  • In a small glass pitcher, stir together the white wine vinegar, sugar, and salt until combined. The mixture will be cloudy and the sugar will dissolve. It will still be grainy from the coarse salt.
  • Pour the vinegar mixture over the red onions in the jar. Stir together and the red onion will begin to reduce in size and be able to fully submerge in the vinegar mixture.
  • Place the lid on the jar and allow it to sit undisturbed for at least 30 minutes at room temperature.
  • Give them a stir and store covered in the refrigerator up to 2 weeks.
