Yes, quick pickled red onions are delicious, but before we get into that, can we talk about that pink? It’s stunning and it makes me want to put these on everything. But if the colour doesn’t convince you, the taste absolutely will.
Quick pickled red onions have a sweet tang, the onions are softened a bit, but they still have a tender crunch, and they are absolutely amazing on everything. I guarantee you’ll fall in love with them and find endless ways to use them.

Notes on Ingredients
Scroll down to the recipe card to find the ingredient quantities and recipe instructions.
- Red onions – You can slice these thick or thin, or dice them, depending on how you plan on using your quick pickled red onions.
- Apple cider vinegar – White vinegar also works, but I prefer the flavour of apple cider vinegar.
- Filtered water
- Sea salt
- Sugar – You can use coconut, cane, or brown sugar for this recipe.
- Lime slices – Adding lime slices infuses the onions with a little more zippy flavour and they also get pickled in the brine, so you’ll have pickled lime slices. And yes, you can eat them!
How to Make Quick Pickled Red Onions
- Make the brine. Boil the vinegar, water, sea salt, and sugar for 2 minutes.
- Add the onions. Boil the onions in the brine for a minute.
- Transfer to a jar. Remove from heat and let the onions and brine cool for 1 minute. Pour the mixture into a jar and add the lime.
- Cool. Allow the pickled red onions to cool to room temperature, then refrigerate.
Tips and Variations
- Let them sit for a day or two before eating. I know it’s hard to wait, but trust me, it’s worth it! After a little time in the fridge, the flavours really meld.
- Use a mandoline. If you have one, use a mandoline slicer to slice your onions evenly and quickly.
- Add some spices or adjust the seasonings. You can use a wide variety of seasonings in this recipe. Try adding mustard seeds, fennel seeds, peppercorns, more sugar, red pepper flakes, or a pickling spice blend.
- Make them spicy. For spicy quick pickled red onions, add a sliced jalapeño (with the seeds) or another hot pepper. Pickled jalapeños are fantastic on tacos!
- Try another veggie. You can use this brine to pickle any vegetable, or you can replace half the onions with a different veggie. Green beans, cauliflower, and carrots are all great options for pickling.
- Add fresh herbs. Tuck sprigs of fresh cilantro, parsley, or dill in with the onions to infuse them with flavour.
My Favourite Ways to Use Quick Pickled Red Onions
- Burgers. Try them on quinoa burgers or grillable veggie burgers.
- Sandwiches. Like this chopped cheese sandwich!
- Tacos. I love pickled red onions on BBQ chickpea tacos.
- Tex-Mex dishes. They’ll add some tangy flavour to these vegan burrito bowls and vegan enchiladas.
- Salads. Diced pickled onions perk up this loaded potato salad.
How to Store
Store quick pickled red onions in an airtight jar in the refrigerator. They will last for up to 2 weeks, and the flavour will continue to develop over time.

Quick Pickled Red Onions
Ingredients
- 2 regular sized red onions
- 1 cup apple cider vinegar
- 1 cup filtered water
- 2 teaspoons sea salt
- 1 tablespoon coconut/cane/brown sugar
- lime slices
- 1 teaspoon peppercorns, crack slightly if you want to release more flavour
Instructions
- In a pot, add the vinegar, water, sea salt, sugar and peppercorns. If using any other additional seasonings, add them now too. Stir together. Bring to a boil for 2 minutes.
- Add in the onions, and allow to boil for 1 minute with the onions.
- Remove from heat, let cool for 1 minute, then pour into a mason jar large enough to hold everything but that allowed the onions to be completely covered in the vinegar mixture. Add in the lime slices and swirl together to mix everything together.
- Allow the mixture to cool completely to room temperature. You can serve immediately once cooled, but if you let it sit and continue to pickle, the flavours meld incredibly. I tried mine three days later and they were perfect. A week is even better. They will last several weeks in your fridge in a mason jar that has the cover tightly screwed on.
- Enjoy!
Notes
- You can use a wide variety of seasonings in this recipe. You could add mustard seeds, fennel seeds, more sugar, jalapeños, anything. It’s really up to you.
- You can use the basic recipe and replace it with your vegetable of choice to pickle any vegetable you want. If pickling peppers, PLEASE use gloves and try not to inhale the fumes of the boiling peppers.
- To store: Store quick pickled red onions in an airtight jar in the refrigerator. They will last for up to 2 weeks, and the flavour will continue to develop over time.

We love pickled red onions and find them so good on burgers. I need to make another batch too.
I love pickled onions! They are super easy, keep well, taste great and go well with a variety of foods.
Hi…you mentioned peppercorns in the instructions but they are not in the ingredients list. How many do you usr? Thanks
Hi Virginia,
I just added them in! I use about a tablespoon. Thanks for pointing that out!
Pickles are always included in my meals. I make onion pickle but another way Will try your recipe too.
I am so in love with pickled onions. Its crazy how much pickling them can transform the flavor from a sort of spicy bite to a sweet and tangy crunch. I love having them on sandwiches or even just as a garnish with a meat dish. This is a great recipe and the pictures are fantastic. Thank you for sharing Jessica!
So happy to hear Billy and so glad you liked my recipe!!
Onions mixed with lemon and pepper, I first know how to mix this mixture. It really works as you say. Then I will try right now as these are quite common ingredients. Thank you!
Hi, i have noticed you used the red cabbage and red onions in your recipe, can i also use the other kinds and still be good as in your recipe.
Hi Luz,
Yes you can use this base for anything to pickle!
My family loves pickled vegetables with fish, on tacos, for a quick snack, anytime really. I have tried a lot of recipes but never one with lime. We just signed up for a CSA and received turnips, radishes, and red onions. This was the perfect recipe for all three. Thank you for your wonderful recipe.
I have made this with regular onions and some reaaaally old limes (leftovers from a party) and yet, it turned out amazing. Really easy and makes the onions so yummy. Cheap and easy way to spice up a lot of dishes, I recommend this recipe and will use it again.
NOTES: I added a teaspoon of peppercorns as the comments suggested and it turned out great.
Awesome so happy that you enjoyed it Petra! Thank you for this great review.
Is. This still good without the sugar?
Hi Deb,
Yes it is!
