Pickled onions are so easy and delicious. I almost always keep a jar in my fridge for salads and sandwiches since they’re tasty and a breeze to make. Plus, these require no canning!
You can pickle any type of onion! Red onions are very common because they turn the onions a pretty shade of pink. But, you can also pickle white onions, yellows onion, or baby pearl onions.
White distilled vinegar is the most common but you can also use white or red wine vinegar, apple cider vinegar, or a mix of different vinegars! I’ve also heard of people using balsamic vinegar or rice wine vinegar for a unique flavor.
Added spices and flavors
You can add a variety of different flavors to your pickled onions. Often a pinch of sugar is used to offset the tartness but this is completely optional. Other common additions or flavors:
- citrus juice or rinds
- bay leafs
- seeds such as fennel, mustard, or coriander
But really, you are only limited by your imagination it’s easy to try different flavors to see what you like.
Making Pickled Onions
These pickled onions are made by thinly slicing onions and soaking them in vinegar. No canning is involved. The most skill you’ll need to make these is deciding to blanch or not to blanch.
The process of blanching onions is to pour boiling water over the sliced onions prior to soaking in the vinegar. I’ve heard different reasons to do this. Some say it keeps them crunchy and others say it makes the flavor more mild.
I use a tea kettle to boil a few cups of water and then pour it over the sliced onions in a strainer in my sink. But, this is completely optional and they are still delicious without blanching.
How long to pickle onions
You can pickle for little as an hour before using, but ideally 24 hours.
Storing and Uses
You can use pickled onions anywhere you’d use a normal raw onion. That means they are delicious on top of sandwiches, burgers, salads, tacos, and appetizers. If you pickle pearl onions you can use them in cocktails, yum!
