Pickled Red Onions

Pickled Red Onions are thinly sliced red onions quickly softened in hot water then pickled in apple cider vinegar with kosher salt. The result is tangy, crisp onions mellowed in sharpness, suitable as a condiment that adds brightness and mild acidity to dishes like sandwiches and salads. The vinegar preserves their texture and flavor when refrigerated.

Ingredients

  • 1 red onion
  • 1 1/2 tsp kosher salt
  • 1 1/2 cup apple cider vinegar

Instructions

    Cup of Yum
  1. Peel the onion and thinly slice it. You can use a sharp knife or a mandoline.
  2. Place the sliced red onions in a colander over a bowl. Pour some hot water over the onions. This will make the onions softer and milder.
  3. Place the sliced onions in a container or a mason jar. Mix in the kosher salt.
  4. Fill the container with apple cider vinegar so it covers the red onions. Cover and refrigerate for at least 30 minutes before serving.

Notes

  • Refrigerate pickled red onions for up to three weeks for best quality.
  • Alternative vinegars like white, rice, or red wine vinegar can be used, changing the flavor profile slightly.
  • Pickled onions can be served to add acidity and crunch to sandwiches, wraps, salads, and bowls.
