How to Pickle Sweet Onions

Quick pickled onions are easy to make and delicious on just about every dish. It’s not complicated to make your own pickled onions, and I have a simple (and delicious!) recipe that can be used and customized to your taste. Plus, you probably already have most of these ingredients in your kitchen and pantry already.

Pickling Onions

While making pickled sweet onions is very easy, there are a few things to note before getting started:

  • Make sure that the jars you’re going to use for the pickled onions have been sterilized properly.
  • Make sure that the jars you are using aren’t chipped or cracked, and the lid should fit airtight.

You can sterilize your jars in one of the following ways:

  1. Oven – Preheat the oven to 250 degrees F and place the empty jars upright on your oven’s tray and heat them for about 20 minutes.
  2. Dishwasher – Place the empty jars, rubber seals, and lids in the dishwasher and wash them.
  3. Stovetop – Place the empty jars in cold water inside a deep saucepan. Bring the saucepan to a boil, starting off on high heat and then reducing the heat to medium for about 10 minutes. Using tongs, remove the jars and dry them using a paper towel, or leave them to air dry on a lined baking tray.
