Pickled red onions are one of those simple recipes that instantly brighten up a meal. Their sharp bite softens into a tangy, slightly sweet crunch, adding both flavor and color wherever they land. A spoonful on tacos, curries, or even a simple sandwich can make the whole dish feel livelier.
This method of quick pickling has deep roots in many cuisines from Latin American kitchens where onions are steeped in citrus and chilies, to Indian thalis where a jar of vinegar-pickled onions often sits alongside curries. The idea is always the same: preserve the onions, boost their flavor, and have a ready condiment that makes every bite more exciting, often enhanced with spices like mustard seeds for extra depth.
I first tried quick pickled onions at a street-side taco stand, where their bright pink hue stood out almost as much as their tangy snap. Since then, I’ve kept a jar in my own fridge, ready to throw on salads, grain bowls, kebabs, or even scrambled eggs. Once you try them, you’ll see why they’ve become a global favorite; they’re quick, versatile, and endlessly useful.

Pickled Red Onions (Quick & Easy)
Ingredients
- 2 medium red onions thinly sliced
- 1 cup 240 ml white vinegar

- 2 teaspoon sugar
- ½ teaspoon ground turmeric

Instructions
- Prep the onions: Peel and thinly slice the red onions into half-moons. Pack into a clean glass jar.

- Slice onions thinly and evenly for best texture and quick pickling.
- Always pour hot brine over onions to help soften them slightly.

- Store in a sterilized glass jar in the fridge for up to 2 weeks.

- Not suitable for freezing as texture becomes mushy.

- Use as a topping for salads, grain bowls, or sandwiches.
- Serve alongside Indian curries, kebabs, or grilled meats.
- Spicy: Add chili flakes or fresh green chilies to the brine.

FAQs
How long do pickled red onions last?
Up to 2–3 weeks in the fridge if kept in a sealed jar.
Can I use white onions instead of red?
Yes, though red onions give the best color and slightly sweeter flavor.
Do I have to boil the brine?
Boiling helps dissolve the sugar and salt and activates the spices. It also slightly softens the onions for better flavor absorption.
Are pickled red onions healthy?
Yes. They’re low-calorie, naturally vegan, and add extra antioxidants from red onions and turmeric.
What dishes do they go with?
They’re great on dal, rice bowls, curries, salads, wraps, or even burgers.
Pickled onions are already a favorite, but with Indian spices they become something special, vibrant, tangy, and layered with warmth. I love having a jar in the fridge to throw on just about anything, from dal and rice to tacos. It’s the quickest way to add color and flavor without any effort.
