A quick and easy recipe for pickled jalapeño slices that delivers a perfect balance of heat and tangy flavor, ideal for tacos, sandwiches, and salads.

Ingredients

Scale
  • 10 medium fresh jalapeños, sliced into thin rounds
  • 1 cup (240 ml) distilled white vinegar
  • 1 cup (240 ml) water
  • 2 tablespoons granulated sugar
  • 1 tablespoon kosher salt
  • 2 garlic cloves, smashed
  • 1 teaspoon black peppercorns
  • 1/2 teaspoon coriander seeds
  • Optional: pinch of red pepper flakes
  • Optional: 1 bay leaf

Instructions

  1. Rinse the jalapeños and pat dry. Using a sharp knife, slice them into thin rounds about 1/8 inch (3 mm) thick without crushing them.
  2. In a small saucepan, combine vinegar, water, sugar, salt, smashed garlic cloves, black peppercorns, and coriander seeds. Bring to a gentle boil over medium heat, stirring occasionally until sugar and salt dissolve.
  3. Place the sliced jalapeños into a clean 16 oz (500 ml) glass jar, layering evenly but not packed too tight.
  4. Carefully pour the hot brine over the jalapeños until fully submerged, pressing down gently to remove air bubbles. Leave about 1/2 inch (1.3 cm) headspace at the top.
  5. Seal the jar tightly and let it cool to room temperature on the counter. Once cooled, transfer the jar to the refrigerator.
  6. Let the jalapeños pickle for at least 24 hours before tasting; they improve after 3 days and can last refrigerated for up to 2 months.

Notes

For crisper slices, blanch jalapeños in boiling water for 30 seconds and plunge into ice water before pickling. Avoid boiling brine too aggressively to preserve bright vinegar tang. Use a wide-mouth jar and avoid overcrowding slices. Let jar sit at room temperature for a few hours before refrigeration to jump-start pickling but do not exceed 12 hours for safety.
