A simple and quick recipe for tangy, crunchy pickled cucumbers and red onions that brighten up any meal or snack. Ready in just 30 minutes with pantry staple ingredients.

Ingredients

Scale
  • 2 medium cucumbers, thinly sliced (preferably English cucumbers)
  • 1 medium red onion, thinly sliced
  • 1 cup (240 ml) white vinegar (can substitute apple cider vinegar)
  • 1 cup (240 ml) water
  • 2 tablespoons granulated sugar
  • 1 tablespoon kosher salt
  • 1 teaspoon pickling spices (optional; mustard seeds, peppercorns, coriander seeds)
  • 12 garlic cloves, smashed (optional)

Instructions

  1. Thinly slice 2 medium cucumbers and 1 medium red onion to about 1/8 inch (3 mm) thickness using a mandoline slicer or sharp knife.
  2. In a small saucepan, combine 1 cup white vinegar, 1 cup water, 2 tablespoons granulated sugar, and 1 tablespoon kosher salt. Heat over medium heat until sugar and salt dissolve, about 3-4 minutes. Remove from heat.
  3. If using, add 1 teaspoon pickling spices and 1-2 smashed garlic cloves to the warm liquid to infuse.
  4. Place the sliced cucumbers and red onions into a clean quart-sized glass jar or airtight container, layering evenly.
  5. Pour the warm pickling liquid over the vegetables, ensuring they are fully submerged. Press down gently if needed, leaving some headspace at the top.
  6. Let the jar cool to room temperature, about 15 minutes. Seal with a lid and refrigerate.
  7. Pickles are ready to eat after at least 30 minutes but taste best after a few hours. Store in the refrigerator for up to 2 weeks.

Notes

Use kosher or pickling salt for best flavor; avoid iodized salt. Thin, even slices ensure consistent crunch. Warm brine helps dissolve sugar and salt and meld flavors. Refrigerate promptly to keep pickles crisp. Adjust sugar and vinegar to taste. Pickles keep well up to 2 weeks but are best within the first week.
