These pickled onions are the perfect topping for almost anything. You can put them on salads, tacos, falafels, avocado toast, sandwiches, the list goes on. They are perfectly sweet, crunchy, tangy and surprisingly so easy to make. In total it only takes about 30 minutes but for 25 of that the onions are soaking so very low effort.  

I also found out red onions have some crazy health benefits, but for me and many others are way too pungent to just eat on their own. The pickling process takes away the pungent flavor of raw onions while still leaving the benefits of regular onions.

Natural Source of Fiber and Prebiotics

Pickled onions are a really great source of fiber and prebiotics. For those who don’t know, prebiotics are a type of fiber that the body is unable to break down so it serves as food to probiotics and is therefore very important to maintaining a healthy gut which is important for general health and well being. 

Speaking of gut health, these also contain apple cider vinegar which has been known to aid in gut health because of its high count of probiotics. That paired with the prebiotics from the onions makes this the perfect combination! 

To start off this recipe cut one red onion into very thin slices. This will help the vinegar absorb faster.

Then separate all the onion rings from each other and pack into a pint sized mason jar.

Bring that up to a mild simmer and pour into the jar with the onions. Then close the lid and let it sit on the counter for about 20-30 minutes or until the onions turn hot pink. Then it's ready for serving!
