Quick Pickled Red Onions are a fast and tangy condiment made with thinly sliced red onions soaked in lemon juice, kosher salt, and freshly cracked black pepper. Perfect for adding a zesty crunch to tacos, sandwiches, burgers, and salads, this simple recipe requires minimal prep time and yields flavorful pickled onions that improve in taste when allowed to marinate longer.

  • Total Time: 10 minutes (includes initial marinating time)
  • Yield: 8 servings

Ingredients

Pickling Ingredients

  • 2 red onions
  • 2 teaspoons kosher salt
  • Freshly cracked black pepper, to taste (about 1/2 teaspoon)
  • 1/2 cup lemon juice (about 3 lemons, or more)

Instructions

  1. Slice the onions: Thinly slice 2 red onions using a sharp knife. Place the slices into a medium-sized bowl.
  2. Add salt and pepper: Sprinkle 2 teaspoons of kosher salt over the sliced onions. Add freshly cracked black pepper to taste, about 1/2 teaspoon or more depending on your preference.
  3. Add lemon juice: Squeeze the juice from at least 3 lemons (or limes) over the salted onions. Use about 1/2 cup of lemon juice or more as desired to cover the onions.
  4. Stir and marinate: Stir the mixture to combine all ingredients well. Let the onions sit for a minimum of 5 minutes to start pickling. For best results, allow them to pickle for at least 30 minutes or up to 2-3 hours, stirring occasionally.
  5. Serve: Use the quick pickled onions as a flavorful topping for turkey burgers, tacos, gyros, veggie sandwiches, pozole soup, quesadillas, burrito bowls, salads, or any dish that could use a fresh, tangy hit.
  6. Store leftovers: Transfer leftovers along with the lemon and salt brine into a tightly sealed container like a glass jar or Tupperware. Refrigerate and use within 2 weeks.

Notes

  • Feel free to adjust the amount of lemon juice to fully cover the onions for better pickling.
  • Pickled onions can be customized with additional spices like chili flakes or herbs if desired.
  • The onions will develop a deeper pink color and mellower flavor if left to pickle longer.
  • Store in the refrigerator for optimum freshness and safety.
