What are Pickled Onions?

Pickled onions are onions that we preserve in a solution of vinegar, water, and salt. The process of pickling involves immersing the onions in this solution and allowing them to marinate for a period of time, usually a few hours to a few days. This results in onions that are tangy, slightly sweet, and crispy.

Ingredients & Substitutions For This Quick Pickled Onions Recipe

The ingredients needed for this quick pickled onions recipe are simple and easily accessible. You will need onions, vinegar, granulated sugar, salt, and hot or warm water. It’s important to use fresh onions and thinly slice them to ensure even pickling.

For the vinegar, any type will do, but apple cider vinegar is a popular choice. I use granulated sugar to balance the tanginess of the vinegar, and salt adds flavor while aiding in the preservation of the onions. Finally, we use hot or warm water to help dissolve the sugar and salt and fully immerse the onions in the pickling solution. Additionally, you can use Himalayan pink salt to add a unique touch of flavor and color to the pickled onions.

You can replace white vinegar with apple cider vinegar, but I’ve tried both, and I prefer the flavor with plain white vinegar.

Helpful Tools

Making pickled onions requires minimal equipment, but a few tools can make the process easier. A mason jar makes an excellent container for storing because it seals airtight and lets you see the contents. A sharp knife and cutting board will help you slice the onions thinly and evenly. Finally, a pot for boiling water and a measuring cup for the pickling solution can be helpful.

Pickling Jar Size Matters

You’ll want to use a jar that is at least 24 ounces (3 cups) to ensure that there is enough room for the onion slices and pickling liquid. A larger jar, such as 32 ounces, is even better. As it will allow for more onions and liquid, resulting in a bigger batch.

It’s also important to note that the jar should be sterilized before using to ensure that the pickled onions will stay fresh for as long as possible. You can do this by washing the jar and its lid with hot, soapy water and then rinsing them well. Then, place the jar and lid in a pot of boiling water for a few minutes to sterilize them.

How to Make This Quick Pickled Onions Recipe

  1. Making these pickled onions is a straightforward process that can be done in just a few simple steps. First, begin by slicing the onions as thinly as possible into little strips. Next, rinse them quickly with boiling water and drain. This will help to remove the strong and pungent raw onion flavor.
  2. Once the onions are prepared, it’s time to make the pickling solution. In a mason jar, combine the vinegar, salt, sugar, and warm water. Stir thoroughly to ensure that the sugar and salt are completely dissolved. This will help to evenly distribute the flavors throughout the pickling solution.
  3. Now, add the sliced onions to the pickling mixture, making sure they are fully immersed in the liquid. Allow the onions to soak in the pickling solution for at least an hour, giving them enough time to absorb the flavors of the pickling solution.
  4. After an hour has passed, cover the mason jar and store it in the fridge for up to three weeks. This will give the onions enough time to fully pickle and develop their unique tangy flavor. Remember to keep the onions submerged in the pickling solution to ensure even pickling.
  5. Once you have prepared your pickled onions, you can enjoy them in a variety of dishes or simply as a tasty snack. Try adding them to salads, sandwiches, tacos, or burgers for an extra burst of flavor. The possibilities are endless!
