If you love a tangy, sweet (& pink) meal topper then you need to make these quick pickled onions! They require super simple ingredients and are ready in no time.

What ingredients are needed for Quick Pickled Onions?
The ingredient list is short and sweet! Most of them you will already have in your kitchen!
The main ingredient is obviously the vinegar. This is what gives the onions that pickled, tangy taste. You can really use whatever vinegar you prefer – distilled white, apple cider, red wine, white wine. Depending on the type of vinegar you use, you will have more or less tang. I went for a combo of distilled white and apple cider.
Other than that you will need water, sugar, salt, mustard seeds and red pepper flakes (if you want a little kick).
How to make Quick Pickled Onions
Slice 1 red onion into thin rounds. Place the onion slices in a heat-proof container – I used these weck jars.
Heat up all of the remaining ingredients in a sauce pan. Once the mixture comes to a boil, stir until the sugar and salt are dissolved. Then, pour the liquid over the onions. Cover them and let them come to room temperature on the counter – about 30 minutes.
Feel free to dig in at this point. BUT, you can also put them in the fridge and let them absorb more of the brining liquid.
How to store Quick Pickled Onions
When you are ready to store the pickled onions, make sure they are in an airtight container. Keep them in the fridge and grab them as you need them.
These are best if eaten within the first 5 days, but can keep in the fridge for a few weeks.
You can use pickled onions on tacos, over soups, in salads. You’ll never want to eat anything again without them!

Hey there Rene, I just made these however, I did not bring the liquid to a boil, just made sure the sugar and salt was melted through.
Will the onions still soften?
Hi Kelly – Yep, they will soften just fine! Enjoy!
I always slice up a red onion and pour in some apple cider vinegar and some dried oregano . I’ll have to give your recipe a go
Oregano sounds like a great add! I feel like there are so many combinations of spices you can use when pickling. This is a great base, and then you can get wild with your creations 🤗
Why red onion? I can’t tell a difference. My daughter can.
Red is typically used for pickling because it has a more mild flavor than white or yellow onions. Plus, it gives you that pretty pink color 😉
Thank you.
