Introduction

If you’ve ever taken a bite of tacos or a salad topped with bright pink onions, you’ve probably thought: “Wow, what is this magic?” That, my friend, is the power of a pickled red onion recipe. These onions are tangy, crunchy, slightly sweet, and they take ordinary food from boring to wow.

I still remember the first time I had them. It was at a little taco stand in Mexico City, nothing fancy, just grilled chicken tacos with a neon pink topping. I asked the vendor what it was, and he smiled like he had been keeping a secret. “Cebollas encurtidas,” he said. Pickled onions. Since then, I’ve been obsessed.

In this guide, we’ll cover everything from quick pickled red onion recipes to old fashioned pickled onion recipes, chef-inspired versions from Jamie Oliver and Bon Appétit, to regional favorites from the UK, Australia, Dominican Republic, and more. You’ll also get spicy, Mexican, and sugar-free versions, plus tips on how to use them on tacos, burgers, and even in cucumber salads.

So, grab a jar and some onions, because by the end you’ll be pickling like a pro.

What Are Pickled Red Onions?

Pickled red onions are raw onions soaked in a vinegar solution with salt, sugar, and spices. The vinegar softens their bite, turns them hot pink, and gives them a sweet tangy crunch.

In my kitchen, I think of them as the “lazy person’s condiment.” Why? Because they are ridiculously easy to make, they last for weeks in the fridge, and they make almost everything taste better. Whether you want the best pickled red onion recipe or an old fashioned pickled onion recipe like grandma made, the process is basically the same: vinegar, onions, and time.
