Quick Pickled Red Onions

Quick Pickled Red Onions are thinly sliced onions soaked in a tangy brine of apple cider vinegar, hot water, sugar, and kosher salt. After 30 minutes at room temperature, they develop a crisp yet slightly softened texture and bright acidic flavor. They add a refreshing, sharp contrast to sandwiches, tacos, salads, or grilled dishes.

Description

This recipe creates Quick Pickled Red Onions by combining thinly sliced red onion half-moons with a hot vinegar-based pickling liquid. The liquid is made from apple cider vinegar, hot water, sugar, and kosher salt to balance acidity and sweetness. The onions are submerged in this seasoned brine and left for 30 minutes at room temperature to quickly soften while retaining some crunch.

The resulting pickled onions offer a crisp texture with a pleasantly sharp and vinegar-forward flavor, complemented by mild sweetness that offsets acidity. The pickling process also mellows the raw onion's pungency, making them more palatable and tangy.

These onions are ideal as a topping or condiment to liven up dishes such as tacos, salads, roasted vegetables, grilled meats, or sandwiches. They provide easy-to-make acidity and crunch without lengthy fermentation or canning.

Quick Pickled Red Onions can be stored in an airtight container in the refrigerator for up to three weeks, allowing for quick grab-and-use convenience. Stir or shake the jar gently before serving to redistribute the brine.

Ingredients

Servings
  • 1 red onion large
  • 3/4 cup apple cider vinegar
  • 1/2 cup water hot
  • 1 to 2 tablespoons granulated sugar can use honey or pure maple syrup
  • 1 teaspoon kosher salt

Instructions

  1. To slice the onion, cut it in half to create half-moons.  Use a very sharp knife or mandoline to create uniform, thin slices. You want the slices to be about 1/8-inch thick.
  2. In a medium jar or bowl, combine the vinegar, warm water, sugar, and salt. Stir until sugar and salt dissolve.
  3. Add the red onion slices and stir, making sure the onion is covered. Let sit for 30 minutes at room temperature.
  4. Serve immediately or store in the refrigerator in a sealed jar or container for up to 3 weeks.

Notes

  • Store the pickled red onions in a sealed jar or airtight container in the refrigerator for up to three weeks to keep them fresh and tangy.
  • Use a very sharp knife or a mandoline to achieve thin, uniform 1/8-inch slices for consistent texture and easy pickling.
  • The longer the onions sit in the brine, the more mellow and flavorful they become, but they also retain crunch if not left too long.
