Quick Pickled Onions
Quick Pickled Onions are wonderful. I am going to get up on my little food blogger stage and tell you how much I love them as a parent.
Okay why as a parent do I love them so much?
Because they give you the freedom to make one singular meal for your family while giving the adults that extra flavor burst.
Pickled Red Onions and other condiments like this are so key to me. If I am making some sort of tacos for dinner but I want more than just the meat base, cheese, and sour cream that my kids are so fond of, bam pickled red onions to the rescue (hot sauce too obviously). But with just 5 minutes of prep I can have these in my fridge and everyone can have taco night their way!
The best part is they are so easy to make and last a while in the fridge, so it is a win-win.
- Red Onion
- Red Wine Vinegar
- Kosher Salt
For a complete detailed list of the ingredients continue towards the bottom of the page.
Remove the skin and thinly slice the onion. I find half circles to be easiest.
Add the sliced onions to a jar or container with a lid, along with the salt and vinegar.
Close and shake everything together. Let rest at least 30 minutes on the countertop shaking every so often before transferring to the fridge. Can be eaten after 30 minutes but they are best after 2 hours.
Tips, Tricks, & Questions
How Long Do Pickled Red Onions Last?
In a covered container in the fridge (a glass jar works best), quick pickled onions should last at least 2 weeks, up to 3 weeks if stored properly.
The vinegar isn’t covering all the onions?!
The amount of vinegar will not cover all the onions right away. The onions will quickly break down from the salt and vinegar. After only about 1 hour they should be mostly covered while they continue to break down.
See the photos below for the timing difference between the pickled onions sitting 15 minutes, 30 minutes, and 1 hour.
I don’t have red wine vinegar, can I substitute a different kind?
Yes, if you are all out of red wine vinegar I suggest using apple cider vinegar instead!
Don’t I need to add sugar? Or if I want to can I add sugar?
You don’t need any type of sugar to make quick pickled red onions, they will be awesome without it. But that being said if you feel like you would like a little to cut down on the vinegar bite go ahead and add in 1 to 2 teaspoons of sugar or maple syrup.
Take the flavors up a notch by adding in more aromatics.
While I love just plain pickled red onions you can take the flavor even farther by adding aromatics such as: Whole Black Pepper, Red Pepper Flakes, Garlic Cloves, & Fresh Herbs like Dill or Cilantro.
