  • 1 medium sized red onion sliced (about 1 cup of sliced red onion)
  • 1/2 cup vinegar use good quality white vinegar, champagne vinegar or apple cider vinegar
  • 1 cup water
  • 1 teaspoon honey optional
  • 1 teaspoon salt
  • Optional Seasonings: See the Recipe Notes


  • Add the vinegar, water, honey (if using), salt and seasonings to a pot or wide pan. Bring to a quick boil and remove from heat. Let cool slightly. The longer you let it cool, the crisper your pickled red onions will be.
  • Add the red onions and press to submerge beneath the pickling brine.
  • Transfer to a container and seal. Use as desired.



Makes about 1 cup of pickled red onions.
Optional Seasonings. Add 1-2 tablespoons of your favorite seasonings for new flavors. Consider Mexican Pickled Red Onions with chili powders, garlic, cumin and Mexican oregano. Consider Cajun Pickled Red Onions with your favorite Cajun seasoning blend. Feel free to experiment. Use your favorites.
Crisp Pickled Red Onions. The heat from the pickling brine will soften the onions more, so if you are seeking pickled red onions that are more crispy, cool the brine longer. If you prefer softer onions, add the red onions immediately to the hot pickling brine.
