Step-by-step guide to pickling onions in vinegar

Step 1: Prepare the onions

Start by peeling and slicing the onions into thin rings or desired shapes. You can choose to keep them whole if you prefer larger pickled onion bulbs.

Step 2: Prepare the brine

In a non-reactive saucepan, combine vinegar, water, sugar, salt, and any whole spices you want to add for flavor. Bring the mixture to a gentle boil, stirring occasionally until the sugar and salt are completely dissolved.

Step 3: Sterilize the jars

Place the glass jars along with their lids in a large pot filled with water. Bring the water to a boil and let the jars simmer for about 10 minutes. This process ensures that the jars are sterile and ready for packaging the pickled onions.

Step 4: Fill the jars with onions and brine

Using tongs or a jar lifter, remove the sterilized jars from the pot. Place a few onion slices or whole onions into each jar, leaving enough headspace at the top. Fill the jars with the prepared brine, ensuring that the onions are completely covered.

Step 5: Seal the jars

Wipe the rims of the jars with a clean cloth or towel to remove any spills or residues. Then, secure the lids tightly onto the jars.

Step 6: Let the onions pickle

Allow the jars to cool at room temperature before transferring them to the refrigerator. This step is crucial for the onions to pickle properly. It is recommended to wait at least 24 hours before using your pickled onions to ensure optimal flavor development.

Step 7: Enjoy your pickled onions!

Once pickled, your onions can be enjoyed on sandwiches, burgers, salads, or as a flavorful addition to your favorite dishes! They can be stored in the refrigerator for several weeks, maintaining their tangy taste and crisp texture.
