Whether you’re a seasoned cook or just starting out, this recipe is foolproof and incredibly rewarding. Let’s get pickling!

Ingredients:

  • 1 large Red onion
  • 1 cup White Vinegar
  • 1 cup Water
  • 1 tablespoon Sugar (you can leave out sugar or use a sugar substitute if you prefer.)
  • 2 teaspoons Kosher salt

    • Preparation and Brine Making

  • Prepare the Onion: Start by peeling the outer papery skin from your large red onion. Trim off the top stem and the root end, but be careful not to cut too deep into the root, as this helps keep the onion slices together. The best way to slice your onion for pickling is thinly. Aim for about 1/8-inch thick slices. You can achieve this using a sharp knife and a steady hand, or for perfectly uniform slices, a mandoline slicer is your best friend. Be extremely cautious if using a mandoline, as they are very sharp. Once sliced, you can separate the rings or leave them in larger segments if that’s easier for you. Some people prefer to cut the onion in half before slicing to make it more manageable.
  • Combine Brine Ingredients: In a small saucepan, combine the white vinegar, water, sugar (if using), and kosher salt. Place the saucepan over medium heat. Stir the ingredients gently until the sugar and salt have completely dissolved. You don’t need to bring this mixture to a rolling boil; a gentle simmer is sufficient. The goal here is to create a well-balanced brine that will both preserve the onions and impart that signature tangy, slightly sweet flavor. Once the sugar and salt are dissolved, remove the saucepan from the heat.

    • The Pickling Process

  • Layer the Onions: Take a clean glass jar or other non-reactive container. An airtight lid is essential for proper storage. I like to use a pint-sized Mason jar. Tightly pack your thinly sliced red onions into the clean jar. The more onions you can fit in without squishing them too much, the more flavor you’ll get in your jar. You might be surprised how much they compress. Make sure the onions are arranged so they will be fully submerged in the brine.
  • Pour the Hot Brine: Carefully pour the warm brine mixture over the onions in the jar. Ensure that the onions are completely covered by the liquid. If there isn’t quite enough brine to cover them all, you can quickly whip up a little extra by following the same ratio of vinegar, water, sugar, and salt. It’s important that the onions are submerged to prevent spoilage and to ensure even pickling. You might want to use a spoon or chopstick to gently press down the onions to make sure they are fully immersed.
  • Cool and Refrigerate: Once the jar is filled with the brine and onions, let it sit on the counter at room temperature for about 30 minutes to an hour. This allows the onions to start the pickling process while the brine is still warm, which can help them absorb the flavors more quickly. After this initial cooling period, secure the lid tightly on the jar and transfer it to the refrigerator.

    • Maturation and Enjoyment

    The most crucial step now is patience! While you can technically eat these pickled red onions after just an hour or two, they truly shine after they’ve had at least 24 hours to marinate in the refrigerator. The longer they sit, the more the flavors will meld and deepen. You’ll notice the onions will soften slightly and turn a beautiful, translucent pinkish-purple color. The brine itself will also take on a lovely hue.

    Once they’ve had sufficient time to pickle, you can drain off some of the brine (or keep it for other uses – it’s delicious on its own!) and add your vibrant pickled onions to any dish that needs a little zing. They are incredibly versatile. Try them on burgers, grilled chicken, fish tacos, quesadillas, or even stirred into a potato salad. They add a refreshing brightness and a delightful crunch that is simply irresistible. Stored in an airtight container in the refrigerator, these pickled red onions will stay delicious for up to 2-3 weeks.
