These Quick Pickled Red Onions are so simple to make and add a beautiful crunchy zing to countless dishes.. A pantry staple for sure!

These onions are definitely a staple in my house, along with my Chili oil. Pickled red onions are perfect for just about anything. A must for taco nights, they add the perfect acidic crunch to salads and chili…you can’t have the Dominican staple, mangu (mashed plantains) without them. They are a great addition to sandwiches, served along rich meats. Basically, anywhere you need something to cut the richness in any dish or add a little zing to brighten it up a bit…then this it and its really easy to do.

Red onions are my preferred onion. Can you pickle other onions? Yes.. but they aren’t as pretty;-) When selecting your onions, make sure its not soft or full of blemishes. You can cut them into rounds but I like to slice them into half moons. More fit in the jar that way. And don’t be afraid to overstuff the jar, pickling will soften the onions.. they will fit. Trust me.

The only ingredients you need for these quick pickled red onions is vinegar, a little bit of water and a big dash of salt. By now you are probably wondering why these are quick pickled. It’s quick pickled because we aren’t using any heat. The traditional pickling method requires you to heat up the vinegar with water, sometimes some spices and sugar. Besides culinary school, I have never used that method. This is how I learned to pickle from my momma and her momma taught her 🙂

As for the vinegar.. use any you like. I have an affinity for distilled white vinegar for things like this.. its slightly tangier and I do love me a good pucker lol but any works just fine. Now for storage I recommend a glass mason jar with a lid but in a pinch I’ve used plastic pint and quart containers. These quick pickled red onions will last several weeks in the fridge but are the best the first 1-2 weeks. Now let’s go pickle some onions!
