Making Pickled Onions Keto, Whole30, and Paleo
You’ll find that a lot of recipes for pickled onions call for refined sugar, but truly, you don’t need it at all. All you need is a bit of lemon juice, and that’s enough to take the edge off the sharp vinegar taste. You’ll quickly be on your way to the best Whole30 condiment ever!
Always remember to check your ingredients labels! That’s just me reminding you, because you don’t hear that enough. But really, because most vinegars are Whole30 compliant, you’re usually okay… but you just never know!
When choosing an apple cider vinegar, I recommend using one that’s raw and unfiltered, like Bragg’s. You’ll get the bonus of beneficial bacteria (probiotics), which are great for improving your gut health! As an added bonus, the flavor is rocking!

Add all ingredients but the onions to a mason jar and stir well.
Add in the onions, pressing down into the apple cider mixture until they’re submerged.
If you need to, top off with a little extra apple cider vinegar until all the onions are covered. Mix well or cover and shake, then set it in the fridge overnight.
