How to Pickle Red Onions

Pickled red onions soften the sharpness of raw onions with a tangy and slightly sweet brine made from vinegar, sugar, salt, and spices like bay leaf and peppercorns. The recipe offers a quick method that cooks the onions briefly in boiling brine for faster readiness and a slow method that achieves a mellow flavor through a longer curing process. Both deliver crisp, bright pickled onions that add acidity and crunch to numerous dishes.

Description

How to Pickle Red Onions provides two approaches for preparing tangy pickled onions. The quick method involves boiling vinegar, water, sugar, salt, bay leaf, and whole black peppercorns to create a hot brine, into which sliced red onions are simmered gently for about five minutes. After cooling, the onions are stored refrigerated and ready to use once chilled. The slow method first soaks sliced onions in salted water to draw out sharpness, then uses a cooled brine of vinegar, water, sugar, bay leaf, and peppercorns poured over the drained onions. This method requires a few days of refrigeration for full flavor development.

Pickled red onions prepared this way offer a balance of sweet, sour, and mildly spicy notes with a crunchy texture, perfect to enhance tacos, salads, sandwiches, or grilled dishes.

Storing the pickled onions in airtight glass containers extends their shelf life, with the quick method lasting up to one month and the slow method up to two months in the refrigerator.

  • ¾ cup red wine vinegar
  • ¼ cup water
  • ¼ cup granulated sugar
  • teaspoon kosher salt

  • ¼ cup cane sugar
  • 1 bay leaf
  • 8 black peppercorns whole

Instructions

Quick Method

  1. Combine vinegar, water, sugar, salt, bay leaf, and black peppercorns in a sauce pot and bring to a boil.
  2. Once boiling, carefully add the onions, simmer on low for five minutes or until the onions begin to soften.
  3. Allow onions to cool then transfer onions and liquid to a container to hold them and refrigerate. They will be ready to use once cooled.

Slow Method

  1. Combine 1 cup water and salt in a bowl and whisk together, add the onions, let stand for one hour
  2. Combine vinegar, remaining ¾ cup water, sugar, bay leaf, and black peppercorns in a sauce pot and bring to a boil, cool immediately.
  3. Once the vinegar brine has cooled, drain the onions and give them a quick rinse and place into a jar or container to hold them
  4. Pour the cooled brine over the top and store in the refrigerator. Ready to use after three days.

Notes

  • Store pickled onions in airtight glass containers in the refrigerator for best freshness and longevity.
  • The quick pickling method yields ready-to-use onions within hours and lasts about one month refrigerated.
  • The slow method mellows flavors more but requires a refrigeration period of about three days before use and can last up to two months refrigerated.
