A quick and easy recipe for tangy pickled red onions ready in just 30 minutes, perfect for adding a fresh, zesty crunch to tacos, salads, and sandwiches.

Ingredients

Scale
  • 2 medium red onions, thinly sliced
  • 1 cup (240 ml) apple cider vinegar
  • 1/2 cup (120 ml) water
  • 1 tablespoon sugar (white or brown)
  • 1 teaspoon kosher salt
  • 1 garlic clove, smashed (optional)
  • 56 whole peppercorns (optional)
  • Pinch of red pepper flakes (optional)

Instructions

  1. Peel and thinly slice 2 medium red onions into half-moons about 1/8-inch (3 mm) thick.
  2. In a medium saucepan, combine 1 cup apple cider vinegar, 1/2 cup water, 1 tablespoon sugar, and 1 teaspoon kosher salt. Add the smashed garlic clove, whole peppercorns, and red pepper flakes if using.
  3. Heat the mixture over medium heat, stirring until the sugar and salt dissolve and the liquid just starts to simmer. Do not boil aggressively.
  4. Place the sliced onions into a heatproof jar or container.
  5. Pour the hot brine over the onions, making sure they are fully submerged. Use a spoon to press the onions down if needed.
  6. Allow the jar to cool to room temperature, then cover and refrigerate for at least 30 minutes before serving.
  7. Taste and adjust the flavor if desired; let sit longer for a tangier or softer texture.

Notes

Use thin slices for even pickling and crisp texture. Do not boil the brine aggressively to preserve crunch. Letting onions rest longer in the fridge mellows the bite and deepens flavor. For a low-sodium version, reduce salt by half. Variations include adding jalapeños for spice or herbs for flavor.
