Why I love this Recipe

I absolutely love this Probiotic Pickled Red Onion recipe because it’s probiotic, and if you know me, I’m all about trying to source nutrients from food. So probiotic food instead of probiotic supplements? Yes, please! F.Y.I. Probiotics are amazing for gut health and tons of other things (learn more here).

It’s quick to make. I know I said that already, but seriously do not doubt my need and dedication to quick & easy (yet delicious) food.

It’s packed full of flavor. No joke, adding these probiotic pickled red onions to any savory dish will take it to a new level (not just taste-wise)! Think nachos, tacos, salads, soups, toast, and sandwiches. Can someone say yum?

Let’s Talk Probiotic Pickled Red Onion Ingredients:

Let’s talk about the ingredients in this Quick Pickled Red Onion recipe!

Red Onion – The star of the show in this recipe, the red onion is used for flavor. It also offers prebiotic qualities which can help nourish your gut on top of the probiotics. Yay for gut healthy condiments!

Raw Garlic Cloves – Adds flavor and prebiotic properties to the probiotic pickled red onions. Trust me, you do not want to skip out on this. Also as tempting as it might be, do not sub garlic powder for raw garlic cloves. Trust me on this, the flavor won’t be the same.

Salt – Any good pickle is salty! It helps create a delicious brine and pickle flavor that you know and love.

Raw (Unpasteurized) Red Wine Vinegar –  Now, this is the important part. If you want this probiotic pickled red onion recipe to be probiotic you have to use raw unpasteurized red wine vinegar. If it’s unfiltered that’s even better. This post isn’t sponsored but here is an Amazon affiliate link to my favorite raw unpasteurized and unfiltered red wine vinegar. It’s honestly so worth it and not too expensive! If you don’t have raw red wine vinegar you can use raw apple cider vinegar but it will change the flavor profile.

How to enjoy Pickled Red Onions

Enjoy these pickled red onion on top of hamburgers, hot dogs, Buddha bowls and more. My favorite way to eat these probiotic raw pickled onions is by blending them into a hummus. Talk about delicious dips…
