Why You Should Make Quick Pickled Red Onions

Making Quick Pickled Red Onions is so easy. You don't need any special canning equipment.

Quick pickles are not meant to be shelf stored long term so you don't need to worry about canning them in a hot water bath canner or having any specialized canning equipment on hand.

Quick Pickles will last 3 to 4 months in the refrigerator.

After you fill jars with the fresh vegetables you want to pickle then pour a hot pickle brine over them you put the jars into the refrigerator and allow them to pickle.

In the case of these Quick Pickled Red Onions, you can eat them in an hour or two.

If you're pickling thicker cut of vegetable and making quick or refrigerator pickles you would allow them to pickle for a couple of days to a week before eating.

Quick pickles are called quick because they are really quick to make and you can start eating them almost immediately.

All you need are a couple of red onions and the ingredients for a basic quick pickle brine.

What is Pickling Salt?

Pickling Salt is a salt product that is specifically made for pickling and canning. It is very fine-grained and dissolves quickly.

Table salt contains iodine and anti-caking products. Table salt is not the same as pickling salt and should not be substituted for pickling salt in this or any other pickle or canning recipe.

Pickling salt does not contain iodine or anti-caking products which can cause the brine to become cloudy and not dissolve completely and may collect at the bottom of the jar.

Now that you have made these awesome quick pickled red onions how are you going to eat them? Pickled onions can be eaten anywhere you would enjoy the flavor of onions.

You can top burgers, hot dogs, sausage, sandwiches, and wraps with Quick Pickled Red Onions.

Helpful tips to make Quick Pickled Onions

  • I doubled the brine for this recipe and made 3 half pint jars of pickled onions.
  • Depending on the size of jar you use you may need to make double the amount of brine. Make one batch of brine at a time and fill the jars. The brine needs to be hot when poured over the onion slices.
  • I used the OXO Zoodle machine to cut the onions into thin strips. Took less than 5 minutes to do 2 onions this way.
  • I used a mixed pickling spice which has all the needed spices. This pickling spice can be used to make quick pickled beets, refrigerator pickles or any other canned pickles recipe.
