  • 1 large red onion
  • 3/4 cup apple cider vinegar
  • 1/2 cup hot water
  • 1 to 2 tablespoons granulated sugar, can use honey or pure maple syrup
  • 1 teaspoon kosher salt


  • To slice the onion, cut it in half to create half-moons.  Use a very sharp knife or mandoline to create uniform, thin slices. You want the slices to be about 1/8-inch thick.
  • In a medium jar or bowl, combine the vinegar, warm water, sugar, and salt. Stir until sugar and salt dissolve.
  • Add the red onion slices and stir, making sure the onion is covered. Let sit for 30 minutes at room temperature.
  • Serve immediately or store in the refrigerator in a sealed jar or container for up to 3 weeks.


Keep pickled red onions in a jar or air tight container in the fridge for up to 3 weeks.
