  • Medium saucepan
  • Measuring cups and spoons
  • Clean glass jar or airtight container

Ingredients
  

  • 1 large red onion thinly sliced
  • 1 cup white vinegar
  • 1 cup water
  • 2 tablespoons granulated sugar
  • 1 teaspoon salt
  • Optional add-ins:
  • ½ teaspoon black peppercorns
  • 1 garlic clove smashed
  • 1 bay leaf
  • ¼ teaspoon red pepper flakes

Instructions
 

  • Prepare the Onions:
  • Peel the red onion and slice it thinly into rounds or half-moons. Place the slices in a clean glass jar or container.
  • Make the Brine:
  • In a medium saucepan, combine the vinegar, water, sugar, and salt.
  • Add optional spices like peppercorns, garlic, bay leaf, or red pepper flakes for extra flavor.
  • Heat the mixture over medium heat, stirring until the sugar and salt dissolve. Remove from heat.
  • Pickle the Onions:
  • Pour the hot brine over the onion slices in the jar, ensuring all onions are fully submerged.
  • Let the mixture cool to room temperature, then seal the jar with a lid.
  • Refrigerate:
  • Store the jar in the refrigerator for at least 1 hour before serving. For best flavor, allow the onions to pickle for 24 hours.
