Instructions
- Bring 3 cups of water to a boil. Thinly slice the onion into rings or half-moons. Turn off the heat, add the onions, and let them sit for 30 to 60 seconds. Drain well.
- In a small jar (8–12 oz), combine the vinegar, salt, sugar, garlic, and peppercorns. Stir until dissolved.
- Add the onions to the jar, pressing them down so they are fully submerged in the liquid.
- Let cool to room temperature, then cover and refrigerate.
- For best flavor, let the onions sit for at least 24 hours before using.
Notes
- If the onions are not fully covered, add a small amount of warm water (up to 1/4 cup).
- For best texture, slice the onions thinly and avoid over-blanching.
- That’s it — no rewrite, just cleaner, tighter, and easier to follow.

How AMAZING would these pickled red onions be on just about any sandwich?? I’ve never pickled onions before and I’m anxious to try these, Mira! Gotta love that pink color!
these look perfect Mira, the color is so pretty!
I have never thought to make pickled onions before, but I do love them! This is such a great recipe, Mira! I love how easy this is. I’m definitely pinning to try out. Sounds delicious!
I like your story. I st here enjoying them in my fish tacos and wondering why I never tried making them 😉 Cheers to you for taking the time to publish your recipe! ? Can’t wait to try it.
Hi Don! Thank you! Hope you like these!
How do I get it to have such bright pink color?
Ni Nina,
Honestly, it is just that some purple onions are way more pigmented than others, this is why these look so bright pink, it is all about what your local store has.
Another trick is to use a little bit of beet in your pickling process if you want to color things a bit without using manufactured additives. I’ve done that with carrots, onions etc.
nutrient content without serving size is not very helpful. 😉 have a great day.
It is for the whole jar.
I’ve made these from this recipe at least 5 times now. Although they say they stay good in the fridge for a month, my experience is that as long as they stay covered by the vinegar they are good for much much longer. I use these on almost everything I can think of. Salad, enchiladas & tacos, with burrata as an appetizer, on caprese stacks, sandwiches, even as a garnish on some soups. I cannot thank you enough for sharing this recipe.
Hi Mira, I stumbled upon your blog and recipes today and what a great find. I worked in th Balkans for 18 months and met my wife in Bulgaria. I miss many things I ate (and drank) there and of course my wife misses things I am always working to create for her. Your recipies will make me a hero. I can’t wait to try these red onions, but especially your Lutenitsa
Hi Rex, glad you found my blog! Hope you find recipes you get to try!
