Description

Quick Pickled Red Onions are a simple and tangy condiment perfect for adding a burst of flavor to salads, tacos, sandwiches, and more. Made with just a few ingredients and ready in under 30 minutes, these pickled onions offer a vibrant color and a perfect balance of acidity and saltiness for any dish.


Ingredients

Scale

Main Ingredients

  • 1 red onion
  • 1/4 cup red wine vinegar
  • 2 teaspoons kosher salt


Instructions

  1. Slice the Onion: Remove the skin from the red onion and thinly slice it into half circles for the best texture and quick pickling.
  2. Combine Ingredients: Place the sliced onion into a jar or container with a lid, then add the 2 teaspoons of kosher salt and 1/4 cup of red wine vinegar.
  3. Shake and Rest: Close the jar tightly and shake to mix all ingredients thoroughly. Let the mixture rest on the countertop for at least 30 minutes, shaking occasionally to help the pickling process.
  4. Chill and Serve: For the best flavor, transfer the pickled onions to the refrigerator after resting and allow them to marinate for at least 2 hours. They can be eaten after 30 minutes but taste best after longer chilling.
  5. Storage: Store the pickled red onions in the fridge where they will keep fresh for up to 2 weeks.

Notes

  • Using kosher salt helps draw out moisture and enhance the flavor without overpowering.
  • Red wine vinegar gives a subtle fruitiness, but white vinegar can be used as a substitute.
  • Pickled onions add a bright contrast to rich meats, creamy cheeses, and fresh vegetables.
  • Shake the jar occasionally during the resting period to ensure even pickling.
  • Keep refrigerated after resting to maintain freshness and texture for up to two weeks.
