What are Pickled Onions?
If you’ve never had a pickled onion, you may be wondering what the heck I’m talking about. I LOVE pickled onions and put them on all sorts of things. I had them years ago, and have been addicted ever since.
Pickled onions can be made with any kind of onion, any shape (whole, sliced, chopped, etc.), and in wide variety of spices and vinegars.
You’ll generally see “pickled onions” as sliced onions (usually red onions) that have been “pickled” in vinegar, sugar, and spices for a period of time. You can pickle the onions for a few minutes or hours, overnight, or can them for long periods of time.
The taste can vary quite a bit depending on the type of pickled onions. However, sliced red pickled onions are generally a bit sweet and sour, and crispy. Don’t worry, they usually don’t taste like pickles, unless of course, you use pickle pickling type spices.
I’m not a canner, although I wish I was, so not sure of the exact way to can these or other onions safely. I store mine in the fridge.
Uses for Pickled Onions:
Like I said, I put pickled onions on all sorts of things. I like to keep a big mason jar of the onions in my fridge. My kids have grown to like them so much they’ll make a batch too!
Here are some of our favorite uses for homemade refrigerator pickled onions:
- Salads – great on lettuce salads
- Gyros – love it on chicken or traditional gyros with feta and tzatziki
- Sandwiches – any kind of sandwich will do
- Burgers & Hot Dogs – my kids love putting them on burgers
- BBQ – the best on pulled pork sandwiches
- Tacos – delicious on fish and shrimp tacos and other Mexican dishes
- Pasta Salad – chop the onions up and add to your favorite pasta salads
- Omelettes – Ok maybe I’m a little crazy but I love chopped pickled onions in my eggs
- Appetizers & Dips – add some chopped pickled onion to your favorite dips and on top of snacks and appetizers

How to Pickle Onions:
Now that I hopefully have you hungry, let’s talk about how to pickle onions! I always wondered how to make pickled onions, and now I’ve been making them for a long time and addicted.
To get started, I like to use a quart size mason jar. You can use any type of container, although I’d suggest not using plastic. Mason jars and glass containers work great!
The recipe makes enough for one quart jar, but you can easily multiple it and make a big batch if you want. Or if you want less, cut it down.
First thing I do, is peel, quarter, and thinly slice red onions. For each quart jar, you’ll need about 3 cups of thinly sliced red onions, but really no need to measure. It may be a bit more or less. Just fill up your mason jar to the top with onions without overly stuffing the jar.
Next, in a small pan, whisk together the water, vinegar, sugar, salt, and black pepper. Bring the mixture to a boil. Then carefully, pour the hot liquid over the onions. Cool slightly, then put the lid on, and refrigerate overnight. As they sit in the fridge the onions will slowly start to turn pink.
The next day, you’ll have these pretty pink pickled onions ready to go! I leave my onions in the jar and just take out what I need when I need them. The onions will last a long time in the fridge!
You can easily adapt this pickled onion recipe with your favorite vinegars and/or spices. I’d suggest making the pickled onions plain like this to start, see what you think, then experiment with different vinegars or spices.

Can i can this recipe- meaning hot water bath and then put on the shelf instead of the refrigerator?
Lisa Huff says
I do not know if these are safe for canning. They are meant to be refrigerated.
Klaudia says
Made them yesterday. I used your advice “You can easily adapt this pickled onion recipe with your favorite vinegars and/or spices.” I used red wine vinerar and added fresh rosemary and thyme. Came up amazing. It is unbelievable that such a simple recipe can have endless variations and, at the same time, brings so much flavor to a dish.
Thank you for sharing it

This recipe was the best out of 3 that I tried. I tried with apple cider vinegar and some honey in other recipes, but this one came out perfect! The best thank you
Lisa Huff says
Thank you so much! The pickled onions are a family favorite here!
Lisa Savage says
I love this recipe! I have used it twice, once with apple cider vinegar and once with distilled white. It turned out amazing both times. Thank you!
Bev says
Do you HAVE to use canning jars with the rubber seals or will a screw on lid work as well. THANKS
Lisa Huff says
Since you’re not actually “canning” these, you can use any container you want, although I personally would suggest staying away from plastic. Just make sure onions are submerged in liquid.

Valentina says
I love pickled onions and think theyr’e a great thing to be sure to always have on hand, at the ready, to spruce a recipe up. Love all of your suggested uses for them!
Vicky says
I would love to make these! They would add such a great flavor to salads and burgers. Any tips for not crying while cutting onions? Besides making my husband cut them? :)
Lisa Huff says
I think having your husband do it is the best idea. :) BUT if that doesn’t work, I like to cut onions in steps. Peel them, then walk away and do something else. Come back and quarter, then walk away for a few minutes. Then slice. Seems to work well for me. Or you could always wear goggles. :)
Sandi says
I can think of all sorts of yummy ways to use these onions.
