Quick Pickled Red Onions

If you want to take your food game to a whole new level with barely lifting a finger (and who doesn’t?), these Quick Pickled Red Onions are for YOU!  

We actually only just started making our own pickled red onions, and it had me wondering… why on earth did we wait so long?  I’ve always admired the beautiful bright purple/pink colour of pickled red onions, but beyond that, they have to be the number one condiment for picking up the flavour of a dish.

I mean, you can put them on so many things.  Tacos, sandwiches, breakfast burritos, falafels (or a falafel salad)….  you get the picture.

Quick Pickled Red Onions

Here is my easy peasy recipe for pickled red onions that we have used for ages. It was modified from the William’s Sonoma Tacos cookbook (highly recommend!).  The best part about these is that you can make them in advance OR make them just before you need them if you haven’t planned ahead.  They will make you look like Martha Stewart in the kitchen and are so satisfying!

These pickled onions will keep in the fridge for up to a few weeks stored in an airtight container.  I’m rather fond of Weck jars… so stylish!

Enjoy! xo
