If you’re just starting out on your journey of making things from scratch, these pickled red onions are a great jumping off point.
I’ve gone down many Youtube and TikTok rabbit holes about homesteading lately. I have so much respect for people who grow and preserve enough food to last for months. If my parents convince me to move with them to their rural property, I’ll be making content like this one day – but for now, I’m a city girl who enjoys making small batch jams and pickles. I love picking up a kilo of ripe fruit from the farmers market, or finding creative ways to use things I’ve grown in my little garden. This recipe requires just two onions and makes 3 small jars of pickles.
Why make your own Pickled Red Onions?
These pickled red onions are one of the quickest pickles to make. They can be ready to eat in as little as 30 minutes! If you want your onions to pickle very quickly (like in the time it takes to cook the rest of your dinner!), I would recommend slicing very very thinly with a mandoline – just be careful of your fingers! This ensures your onion slices are super thin and even. I used a sharp knife and just took my time to get the slices as thin as possible. My slices were a little thicker and my pickles were perfect on a sandwich the next day.
Pickled Red Onions are so delicious and versatile! They’re sweet but tangy, giving a little bit of brightness, zing and colour to anything you wish to put them with. Pop them onto your avocado toast or eggs. Add them to your salads or tacos. They’re also absolutely delicious on a juicy burger or sandwich. And also give a pop of bright pink colour on a cheeseboard. Honestly, I think I need to keep a jar of these in my fridge at all times!
Preserving helps combat food waste AND helps your budget. There is nothing more frustrating than seeing slimy vegetables in the bottom of the fridge! This recipe actually came about because I had to buy 1kg of red onions when I only needed one or two. I didn’t want to waste the rest – so I made these pickles instead! Now they will last for much longer in the fridge. I love a fancy artisan pickle from the farmers market as much as the next foodie, but they can be so expensive. Making your own is so worth it!
You can customise your pickles however you like! I used pink peppercorns in this recipe, in part because of their pretty colour. But I also love their flavour, which is a little more mild and fruity compared to black pepper. But of course, this recipe is just a starting point and you can get creative with flavours. I’ve seen versions with star anise, mustard seeds, fresh thyme, garlic, bay leaves or sliced chilli. Seriously, almost anything goes! Play around with the types of vinegar and the proportions. You can really make this recipe your own.
How to make Pickled Red Onions
The formula you need for pickling almost anything is pretty simple – salt, sugar, acid (in most cases vinegar) and whichever herbs or spices you like for flavour. Vinegar is a magical ingredient that preserves vegetables by both slowing down their decomposition, and inhibiting the growth of microorganisms like bacteria and mould. Sterilising your jars is also an important step in the process. I have instructions below.
These pickled red onions do not require a lot of prep work. Peel and slice your onions carefully, either with a mandoline or a sharp knife and pack them into the sterilised jars tightly. I added 1/2 teaspoon of pink peppercorns into the top of each jar.
Then make your brine in a saucepan with water, white vinegar, sugar and salt (the full recipe is below), bringing just to the boil and stirring until the sugar has completely dissolved. Allow to cool.
Pour the cooled brine over the top of the onions, covering completely. Seal with lids and place into the fridge for as little as 30 minutes. The pickles will be good, flavoursome and crunchy after this short time but the flavours will continue to develop and improve over time. I also highly recommend labelling your jars with the name and date.
That’s it! These pickled red onions are easy to make and so delicious. Yesterday I made a pastrami and swiss cheese sandwich, with a little mustard and some of these onions and it was *chef’s kiss*. I can’t wait to eat them with basically every meal from now on!

Pickled Red Onions with Pink Peppercorns
Pickled Red Onions are perfect to try if you are just starting out making pickles! They are absolutely delicious, quick to prep and versatile enough to add flavour to many kinds of dishes, from sandwiches, eggs, burgers, tacos, salads and more!
Ingredients
- 2 red onions
- 2 cups white vinegar
- 2 cups water
- 1/2 cup sugar
- 1 tablespoon salt
- 1 1/2 teaspoons pink peppercorns (I used 1/2 teaspoon per jar)
Instructions
-
First, sterilise your jars. Wash jars, metal lids and bottles in hot, soapy water. Rinse thoroughly. Boil in a large pot of water for 10-15 minutes. Remove with tongs. Dry upside down on a clean towel or in a low oven (about 120°C/250°F) for 10-15 minutes until completely dry. Remove carefully with oven mits or a tea towel as the glass is very hot.
-
Peel onions and slice thinly, either using a mandoline or sharp knife.
-
To make the brine, place the white vinegar, water, sugar and salt into a saucepan over medium heat and stir until the sugar and salt completely dissolve. Set aside and allow to cool.
-
Pack the onions into the jars and add 1/2 teaspoon of pink peppercorns into the top of each jar. Pour the cooled brine over the top of the onion to fully cover. Secure the lids and place into the fridge to pickle.
-
Very thinly sliced pickles will be ready in 30 minutes – 1 hour. Thicker sliced onions should be ready by the next day. They should be bright pink in colour and tender with a slight crunch when ready. Keep refrigerated and use within about 2 weeks.
Recipe Notes
Note: I used 3 x 200ml jars for this amount of onions and had a little brine leftover.
