Hubby loves pickled onions. 
I just 'pinched' your recipe.

These were delicious! Used them for several meals throughout the week from shrimp tacos to bbq chicken pizza even in my morning omlete. Always wanted to pickle onions finally got around to it. Thank you for the easy recipe and tasty onions lol!

Thank you, Ali
this is such a great way to have onions on-hand since I'm the only fresh "onion fan" in our house. I would normally forgo having fresh onions on my burger, salads, etc. because I couldn't consume an entire onion by myself and that would be wasteful. This recipe solves this dilemma for me and probably many others. I used a large red onion and sliced it on my mandolin to nicely fill two jars - but had to double+ the vinegar to cover the onions. I also added a few peppercorns and one small bay leaf to each jar after simmering with the vinegar, salt and sugar. So easy and tasty!

You’re blog is great.  I found you through the CopyMeThat app and I am so glad i did.  I will be following you now.

These are exactly what I was looking for. Saving this recipe! (I used monk fruit sweetener instead of regular sugar and it worked perfectly!)

This recipe was my first attempt to pickling onions - it came out great! I used a red onion with a few jalapeño slices and some garlic in the jar.  Now I need to go to the store and get sandwich fixings to put it on ;-) Thanks for posting/sharing.

These are fantastic and sure to go into our regular rotation.  The only change I made was to increase everything by 1/4 to fully cover the onions in my pint size mason jar. Thinking of adding the peppercorns next time, but these are amazing as is!  Thanks for a great recipe!

I wound up having to use a Texas yellow onion, because my red was kind of slimy (bleh!) 
Also, I had to triple the liquid portion of the recipe, because apparently I misjudged what two small yellow onions might look like. I'm from Texas though, so maybe my measurement judgment is a little off, LOL

Anywho thanks for posting this!

First of all, you are officially my "go to" for ideas and recipes. I whipped these pickled onion last week and my husband LOVES them. he puts them on and in everything.
Your energy bites are the est I ever had; you pad Thai - yum; the Vietnamese spring rolls, Pho, and Hot and Sour Soup - all amazing. I made homemade pappardelle with the cajun cream sauce on Saturday and also - delicious! Every single think we have made has been fantastic.

Super quick and very yummy, I was out of apple cider vinegar so used balsamic instead. Fifth time making  x

This was my first time making pickled onions and they turned out great!! Thanks for this quick, easy, and delicious recipe!

Tried this recipe and the onions taste delicious! I added some pepper to it, saw some of the reviews stating they added other ingredients. Will try doing that next time! Thanks for this simple fuss-free recipe.

Yumm. Perfect for my soft tacos. And so EASY

Whenever I pinterest search a recipe - I look for yours! Like the rest, I love these. They're good on absolutely everything, but my favorite (and what I made them for today) is to go with carnitas. I always go back to this recipe of yours so I thought it was time I thanked you! Sometimes I follow my heart and add some extras, and I really like bay leaves, garlic, and some crushed red pepper. Thanks for being awesome!

In general descriptions you mention water as an ingredient, yet in recipe itself, it is not in there. Is there to be water in this recipe? I see others either had to add or double recipe to have enough liquid to cover onion.

Sounds fast and easy. I love onions so I’ll be trying this out. Thanks. Sue.  sue.s73@yahoo.com

I made this recipe with honey as my sweetner excellent.

Love! 
I have done your recipe 3 times.  I use honey. 
I served over cooled boiled green beans.  Oh my, love the combination!  Husband too!  And visually,  it makes a beautiful side dish too! 
I also use them over my salads.
I love that I can keep them in a tight jar in my fridge and use anytime I want too! 
Thank you!
