Quick Pickled Red Onions

You’ve probably seen these pretty pickled red onions on a boatload of my recipes around here over the years.

I always thought it was too simple a recipe to share, but after seeing how crazy popular my pickled onion reel was on Instagram, I decided these bad boys really do need their own post on P&C!

These ultra-vibrant onions are the perfect combination of crisp and tangy and they’re such a fantastic way to add a bright and refreshing flavor boost to your dishes.

My husband and I are obsessed with them and try to keep a fresh jar on hand each week. They’re easily one of our favorite condiments and add a perfect pop of color and tartness!

Pickled Red Onions Serving Suggestions

This rockin’ red onions are so wonderfully easy to make and they add fantastic flavor to everything you add them to.

  • quesadillas
  • enchiladas
  • tostadas
  • salads
  • grain bowls

There are zillions of other uses for them too! Paul likes adding them to a bagel with cream cheese and sliced jalapeños and I’m a huge fan of adding them to everything from avocado toast to stuffed sweet potatoes.

Red onion… purple onion… whatever you call it, grab one and let’s get pickling!

Ingredients Needed

  • 1 medium red onion
  • 3/4 cup white vinegar
  • 1/4 cup water
  • 1 tsp fine sea salt
  • 1-1.5 TBSP sweetener, to taste

For the sweetener (it cuts the bite of the vinegar a little and is totally optional) Paul likes to use white sugar when he makes them. Honey and maple syrup are also excellent options. I’m guilty of skipping the sweet stuff entirely and adding black pepper instead. I like them tart!

Optional Extras

Black Peppercorns are a popular add-in if you have some handy.

You can also take things to the next level with some thinly sliced jalapeño *chef’s kiss* — I love this tasty add-in! You can also add crushed red pepper flakes to add some fire to your pickled red onions.

What type of vinegar should I use?

Most pickled onion recipes call for plain white vinegar. The same kind you can use for a zillion uses around the house/kitchen. There are plenty varieties you can play around with though for slightly different flavors.

I love using white wine vinegar, white balsamic vinegar, apple cider vinegar, or rice vinegar. All are great options and you can mix and match too for a totally custom jar of pickled onions.

How to pickle red onions

  1. Peel and slice a medium red onion super thin.
  2. Heat the vinegar, water, salt and sweetener or choice in a saucepan until bubbly and pour over onions in a mason jar.
  3. Then simply marinate for 30 minutes and enjoy!

For only 10 minutes or so of effort you’ll have the most delicious condiment for all your tasty eats.

These quick pickled red onions are fantastic right away (such glorious crispness!) and great over the next week or so too. Keep them in an airtight jar (mason jars and weck jars work great) in the fridge and pop these pretties on everything!
