Pickled Red Onions

There’s something incredibly satisfying about a jar of vibrant, jewel-toned pickled red onions. They’re not just pretty; they’re a flavor powerhouse that can elevate countless dishes. From adding a zesty crunch to tacos and sandwiches to bringin extractg a bright, tangy counterpoint to rich meats and creamy avocado toast, these pickled onions are a true kitchen cbeef hameleon. And the best part? They are astonishingly simple to make. Forget those store-bought varieties that can sometimes be overly sweet or lacking in punch. With just a few basic ingredients and a little bit of patience, you can have your own batch of perfectly balanced pickled red onions ready to go. This recipe is my go-to, and it consistently delivers delicious results.

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
  • Instructions:

    1. Begin extract by preparing your red onion. The key here is to slice it thinly. I find that using a mandoline slicer is the easiest way to achieve uniform, paper-thin slices, which will pickle more evenly and create a more pleasing texture. If you don’t have a mandoline, a sharp knife will work perfectly well, just take your time and aim for consistent thickness. You want slices that are almost translucent. After slicing, you can choose to separate the rings if you like, or leave them in larger pieces. Some people prefer to give the sliced onions a quick rinse under cold water to remove some of the sharpness, then pat them dry. This is an optional step, but it can result in a milder pickled onion. Place your beautifully sliced red onion into a heatproof jar or a sturdy bowl that can withstand heat. A mason jar is ideal for storage later.

    2. Now, let’s prepare the pickling brine. In a small saucepan, combine the white vinegar, water, sugar (if using), and kosher salt. Place the saucepan over medium heat on your stovetop. Stir the mixture gently with a whisk or spoon until the sugar and salt have completely dissolved. It’s important that everything is fully incorporated before you proceed. Bring the mixture just to a simmer – you don’t need a rolling boil, just a gentle bubbling around the edges is sufficient. This process helps to meld the flavors and activate the salt and sugar. Once dissolved and simmering, remove the saucepan from the heat.

    3. It’s time to combine the brine and the onions. Carefully pour the hot pickling brine over the sliced red onions in your jar or bowl. Ensure that the onions are fully submerged in the liquid. If any slices are sticking out, gently press them down with a spoon. The heat from the brine will begin extract to soften the onions and start the pickling process immediately, imbuing them with that characteristic vibrant pink hue. You’ll notice the color change happening fairly quickly. Be cautious when handling the hot liquid.

    4. Allow the mixture to cool at room temperature. This is a crucial step for developing the flavors. Let the jar or bowl sit on your counter for at least 30 minutes to an hour, or until it has cooled down significantly. During this time, the onions will continue to soften and absorb the tangy, slightly sweet brine. This initial cooling period allows the flavors to meld beautifully before you introduce the cold. Once the mixture has reached a temperature that is no longer hot to the touch, you can cover the jar or bowl.

    5. Refrigerate and let the magic happen! Once cooled, cover your jar or bowl tightly and place it in the refrigerator. For the best flavor, I recommend letting them pickle for at least a few hours, but they truly shine after 24 hours. The longer they sit in the refrigerator, the more developed and intense the flavor will become. They will keep in the refrigerator for several weeks, making them a fantastic pantry staple. You’ll find yourself reaching for them constantly. To serve, simply drain them from the brine or use them with a little of the liquid for extra flavor. Enjoy their delightful crunch and vibrant tang on salads, avocado toast, burgers, tacos, or anywhere you need a burst of brightness!

    Frequently Asked Questions:

    How long do pickled red onions last?

    When stored properly in an airtight container in the refrigerator, these pickled red onions can last for several weeks, often up to 2-3 weeks. The brine acts as a preservative, but their texture will eventually soften over time.

    Can I make pickled red onions without sugar?

    Yes, you absolutely can! While sugar helps balance the acidity and adds a touch of sweetness, you can omit it entirely for a purely tangy pickle. Alternatively, you can use a natural sweetener like maple syrup or honey in a slightly smaller quantity if you prefer a hint of sweetness without refined sugar.

    What is the best type of onion to use for pickling?

    Red onions are the classic choice due to their vibrant color and slightly milder, sweeter flavor when pickled. However, you can also experiment with white or yellow onions, though the color won’t be as striking.
