I’ve been on the homemade pickled red onions train for…honestly, I don’t know how long! I can’t remember the last time I didn’t have a jar in the fridge. And after relentlessly tweaking this recipe for years, I’d say I got it down pat.

With only two main ingredients, this recipe is as simple as it gets. However, I’ve added a few optional ingredients that will take your onions to the next level.

What are pickled red onions?

Pickled red onions are red onion slices that have been pickled in vinegar. Pickling is a process that preserves the lifespan of food by either anaerobic fermentation in brine or immersion in vinegar.

Pickling red onions transforms their original sharp taste and raw texture into a crave-worthy, tangy, and crisp condiment. It’s also an excellent way to store an onion when a recipe doesn’t call for the entire onion.

Tools You need for pickled red onions

Making pickled red onions doesn’t take much, but these three tools will make the process beyond easy:

  • Mandoline – This is the ultimate game-changer! Slice your onions in literally no time.
  • Cut-resistant gloves – Keep your fingers safe while using the mandolin.
  • Glass storage jars – Use these to pickle the onions and store them in the refrigerator
