Ingredients

  • 1 large red onion thinly sliced into rings or half-moons
  • 1 cup white vinegar or apple cider vinegar
  • 1 cup warm water
  • 1 tablespoon granulated sugar
  • 1 teaspoon salt
  • 1/2 teaspoon whole black peppercorns optional
  • 1 bay leaf optional

Instructions

  1. Slice the red onion as thin as you can — a mandoline is ideal, but a sharp knife works fine. Separate the rings and pack them into a clean pint jar or glass bowl.
  2. In a measuring cup, stir together the warm water, vinegar, sugar, and salt until the sugar and salt dissolve completely.
  3. Pour the brine over the onions, making sure they're fully submerged. Add peppercorns and bay leaf if using. Press onions down with a spoon if they float.
  4. Let sit at room temperature for at least 30 minutes. The onions will turn bright pink almost immediately. For best flavor, refrigerate for at least 1 hour before using.
  5. Store in the fridge with a lid for up to 2 weeks. They get better with time.

Recipe Notes

Variations: Add a sliced jalapeno for spicy pickled onions. Add fresh dill and garlic for a sandwich-perfect version. Double the sugar and add a cinnamon stick for sweet pickled onions that are incredible on a cheese board.
