Quick Pickled Red Onions

Cheap, easy to make and an absolutely smashing addition to burgers, kebabs and even a cheese and onion sarnie! These quick pickled red onions are one of those little extras that can completely change a meal. They bring a lovely sharpness and sweetness that cuts through rich, fatty or cheesy foods and adds a bit of much-needed crunch.

I particularly like adding them to a cheese savoury sandwich when I’m on nightshift, but they’re brilliant with burgers, wraps, grilled meats and, as we’re about to demonstrate, a proper homemade kebab.

The beauty of these is that they take very little effort. There’s no complicated pickling process or cupboard full of specialist ingredients — just a handful of everyday stuff and a little bit of patience. Once they’re made, they keep really well in a sterilised jar, so there’s absolutely no reason not to make a bigger batch.

And they actually get better with time. The onions soften slightly, that gorgeous pink colour develops and the sharpness mellows into something properly addictive.

Keep a jar in the fridge and you’ll find yourself putting them on bloody everything. Especially good as part of our whole kebab recipe:

How To Make Quick Pickled Red Onions

The great thing about this quick pickled red onions recipe is that you can have a jar ready in minutes. There’s no need for fancy equipment or a cupboard full of unusual ingredients. A red onion, some apple cider vinegar and a few simple additions are all you need. The vinegar gives the onions their lovely sharpness, while a little sweetness balances everything out.

Cush’s Notes

To sterilise jars, wash thoroughly then place in the oven at 130 degrees for around 10 minutes. While that’s happening, boil the lids for around 5 minutes.
We like these far far better than red cabbage with our Doner Kebab recipe!
