Fermented foods are one of the foundations of a healing diet. Rich with probiotic benefits, ferments are so good for your gut! However, they take a bit of extra effort to make. Sometimes I find myself wanted a yummy fermented food topping for a meal but I don’t have three days to wait for it. That’s where quick pickled onions come in!

These quick pickled onions still feature probiotic benefits, but are made in a fraction of the time. They are so perfect for putting on burgers and have become a staple in my house over the past several weeks. They’re made with apple cider vinegar and are paleo, AIP, and whole30 compliant. No corn-based vinegar here!

The Ingredients You Need For The Quick Pickled Onions


Red onion

Red onions are one of my favorite veggies! They’re cheap, easy to find, and they’re so wonderfully peppery. Spice is something I really miss not having nightshades and red onions are an amazing way to add spice.


Apple cider vinegar

Rather than using a white vinegar, this recipe uses apple cider vinegar. White vinegar is often made from a corn base which is no what those of us who are grain free want to be sneaking into our food.


Sea salt


The supplies


A 6-8 oz jar with a lid

Use a weck jar or canning jar for this.


A medium pot and strainer

This is for par-blanching the onions to make them softer and take away some of the bite.
