Ingredients:

  • 2 medium red onions ((or 3 small ones))
  • 1 1/4 cup water
  • 1 1/4 cup white vinegar
  • 3 tbsp sugar (of choice (see notes))
  • 1 tbsp sea salt
  • 1/4-1/2 tsp red pepper flakes ((optional))
  • Instructions:

    1. Prepare the Onions: The first step is to get your red onions ready for pickling. Peel the outer papery skin from the red onions. You can do this under running water to help prevent your eyes from watering, or just quickly peel them on a cutting board. Once peeled, trim off the very top stem end and the root end. You want to leave the root end mostly intact if possible, as it helps to hold the onion slices together initially, making them easier to handle. Slice the red onions as thinly as you can. A mandoline slicer is your best friend here for achieving uniform, paper-thin slices, which are ideal for pickling. If you don’t have a mandoline, a sharp knife and a steady hand will do the job, just aim for consistency in thickness. The thinner the slices, the quicker they will pickle and the more tender they will become. Place your thinly sliced onions into a clean glass jar or a heatproof bowl. I usually aim for a jar that holds at least 2 cups.

    2. Make the Brine: Now, let’s create the magical brine that will transform these raw onions. In a small saucepan, combine the water, white vinegar, sugar, and sea salt. Stir these ingredients together well. Place the saucepan over medium heat on your stovetop. Bring the mixture to a gentle simmer, stirring occasionally, just until the sugar and salt have completely dissolved. It’s important that everything is fully dissolved for an even flavor distribution. If you’re using the red pepper flakes for a little kick, you can add them to the brine at this stage. Taste the brine once it’s heated and the salt and sugar are dissolved. It should be pleasantly tangy and slightly sweet. If you prefer a sweeter pickle, you can add a touch more sugar. Conversely, if you like it more vinegary, a tiny splash more vinegar can be added, but be cautious not to overpower the other flavors. This simple brine is the heart of the pickling process.

    3. Combine and Infuse: Once the brine is ready and the sugar and salt are dissolved, carefully pour the hot brine over the sliced red onions in your jar or bowl. Make sure that all the onion slices are submerged in the brine. If they aren’t completely covered, you can gently press them down with a spoon or add a tiny bit more water and vinegar in equal parts to ensure they are all submerged. The hot brine will begin extract to cook the onions slightly and start the pickling process. You’ll notice the onions begin extract to soften and their vibrant color will deepen as they interact with the vinegar. This is where the magic truly starts to happen.

    4. Cool and Chill: Allow the jar or bowl of onions and brine to cool down to room temperature. This is a crucial step. Don’t rush this process by putting a hot jar directly into the refrigerator, as it can risk cracking the glass or affecting the texture of the onions. Once the mixture has reached room temperature, you can seal the jar tightly with a lid. Then, transfer the jar to the refrigerator. For the best flavor and texture, I recommend letting the pickled red onions chill in the refrigerator for at least 30 minutes to an hour before using them. However, they will continue to develop and deepen in flavor over time.

    5. Maturation and Storage: The longer these pickled red onions sit in the refrigerator, the more developed their flavor will become. While they are enjoyable after an hour, they are truly magnificent after 24 hours. The onions will become more tender and the flavors will meld beautifully. You’ll notice a significant difference in taste and texture between an onion that’s been pickled for an hour versus one that has been brined for a day or more. Store your pickled red onions in the refrigerator. They will keep well for about 2 to 3 weeks. The brine itself is also delicious and can be used as a vinaigrette for salads or a marinade for chicken or beef. When you’re ready to serve, simply spoon out as many pickled onions as you need. The remaining onions will continue to pickle in the brine. Enjoy the bright, zesty crunch they add to your culinary creations!

    Notes on Sugar: I’ve listed “sugar (of choice)” because you can experiment here! While granulated white sugar is standard and yields a clean sweetness, you can also use brown sugar for a richer, molasses-like note, or even coconut sugar for a slightly different flavor profile. The amount of sugar can also be adjusted to your preference – start with the recommended amount and taste the brine before pouring it over the onions.

    Frequently Asked Questions:

    How long do pickled red onions last?

    Properly stored in an airtight container in the refrigerator, your pickled red onions should stay fresh and delicious for about 2 to 3 weeks. You’ll notice the color might deepen slightly over time, but the flavor will remain excellent. Always check for any signs of spoilage before consuming, though this is quite rare with proper pickling!

    Can I use a different kind of vinegar?

    Absolutely! While white vinegar or apple cider vinegar are classic choices for pickled red onions, feel free to experiment. Red grape juice vinegar will impart a deeper color and a slightly different flavor profile. Rice vinegar offers a milder, more subtle tang. Just ensure the vinegar has at least a 5% acidity content for safe pickling.

    Can I adjust the sweetness or spiciness?

    Yes, you certainly can! For a sweeter pickle, simply increase the amount of sugar. For a spicier kick, add a pinch of red pepper flakes to the brine, or include a sliced jalapeño or a few peppercorns. These pickles are meant to be customized to your taste preferences!
