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:

The beauty of this recipe lies in its simplicity. It’s a three-step process that requires minimal active cooking time and uses ingredients you likely already have on hand. Let’s get started!

Preparation of the Onions

The first step is all about getting your onions ready to absorb all that delicious pickling brine. You’ll want to start by peeling your red onions. Remove the papery outer skin, and then trim off the top and bottom ends. For the best texture and most even pickling, I like to slice the onions thinly. Aim for slices that are about 1/8 to 1/4 inch thick. You can achieve this with a sharp knife and a cutting board, or if you have one, a mandoline slicer is your best friend here for consistent, paper-thin rounds. Place the sliced onions into a heatproof bowl or a large jar. I prefer using a large glass jar for pickling as it makes storage and serving super convenient, and you can easily see the beautiful color change happening.

Creating the Pickling Brine

Now, let’s make that magical brine. In a medium saucepan, combine the water, white vinegar, sugar, and sea salt. If you’re using red pepper flakes for a little kick, add them now. The type of sugar you use can subtly impact the flavor. Granulated white sugar is standard and provides a clean sweetness. You could also experiment with brown sugar for a slightly deeper, molasses note, or even a touch of maple syrup for a unique twist, though this might alter the color slightly.

Place the saucepan over medium heat. Stir the mixture frequently to ensure the sugar and salt dissolve completely. You don’t need to bring this to a rolling boil; just heat it until the sugar and salt have fully dissolved and the liquid is hot. This usually takes just a few minutes. Once everything is dissolved, remove the saucepan from the heat.

Assembling and Pickling

Carefully pour the hot pickling brine over the sliced red onions in your bowl or jar. Make sure the onions are completely submerged in the brine. If they float to the top, you can gently press them down with a spoon or use a smaller jar or container to help keep them submerged. The heat from the brine will begin extract to soften the onions and start the pickling process. You’ll notice the onions starting to transform in color almost immediately, turning a beautiful, vibrant pink. This is the magic happening!

Cooling and Refrigerating

Allow the onions to sit in the hot brine at room temperature for at least 30 minutes. During this time, they will continue to soften and absorb the flavors of the brine. This initial cooling period is crucial for developing the right texture. After 30 minutes, you can cover the bowl or jar tightly. If you’re using a jar, screw on the lid. Transfer the container to the refrigerator. The onions will continue to pickle and develop even more flavor as they chill.

Enjoying Your Pickled Onions

While you can technically eat them after the initial 30-minute room temperature soak, I highly recommend letting them chill in the refrigerator for at least an hour, or ideally, a few hours. The longer they sit in the fridge, the more pronounced and delicious the flavors become. They’re typically best after at least 2-3 hours, and even better after a full day. Once refrigerated, pickled red onions will last for about 2-3 weeks. You can use them straight from the jar! Spoon them over tacos, pile them high on avocado toast, add them to your favorite salads, burgers, or sandwiches, or serve them alongside grilled meats and fish. Their versatility is endless, and their bright, tangy flavor is sure to become a staple in your culinary repertoire. Enjoy the fruits (or rather, vegetables!) of your easy labor!
