Hiya friends! If you’re looking to add a burst of flavour to every meal, whip up these Quick Pickled Red Onions! They’re the perfect combination of tangy and subtly sweet and one of my favourite condiments to keep in the fridge at all times. Once you learn how easy this 5-ingredient recipe is to make at home from scratch, you’ll never want to purchase them at the grocery store again!
Trust me when I say this recipe is simple enough for the ultimate beginners and newbie cooks. It’s a 5-ingredient recipe that’s ready to marinate in 10 minutes or less – and all you need is a cutting board, a sharp knife (or mandoline), and a glass jar! It’s the perfect condiment for topping my Vegan Lentil Burger Patties, Vegan Tacos to add some crunch!
Now, let me show you how easy it is to make these pickled onions so you can make them pronto!
Learning how to make quick pickled onions at home is so much easier than you think!
Start by slicing the onions into very thin rings or half moons. I find this easiest to do using a mandoline slicer, but a sharp knife works well, too!
Once the onions are prepped, add them to a large, 750 ml mason jar along with peppercorns and one bayleaf. Set the jar aside, then begin to prep the vinegar mixture.
In a small saucepan, pour in the vinegar, water, salt and agave. Bring the mixture to a low simmer, then as soon as you see bubbles, turn off the heat.
Immediately pour the warm vinegar mixture directly over the sliced onions in the jar. Gently press the onions down with a spoon to make sure they are fully submerged in the liquid. Tightly screw on the lid, then place the pickled red onions in the fridge and marinate for at least 30 minutes before using (I prefer to leave them overnight!).
Serve as a topping on all of your favourite savoury recipes, or as desired.
As mentioned, I love these pickled onions on top of my Lentil Burger Patties and my Favourite Vegan Tacos with Plant-Based Ground, but they can be served with many other dishes! Here are a few additional suggestions to inspire you:
When stored in an air-tight glass jar, these quick pickled onions will keep for up to 2 weeks in the fridge. To make the pickled onions last as long as possible, keep the onions submerged in the pickling solution.
Yes, technically you can use this method to pickle more than red onion slices, but it won’t have the same bright, vibrant pink colour. Feel free to give it a try using a variety of fresh onions including white onions, yellow onions, or sweet onions.
No. Cooking the onions before pickling them is not necessary! They will soften in the pickling liquid while remaining the perfect amount of crunchy. All you truly need is 10 minutes of prep work.
Absolutely! This quick pickled onions recipe is meant to be basic enough to pair with as many dishes as possible. Feel free to experiment with different additions such as fresh herbs, mustard seeds, red pepper flakes, garlic, etc.
