materials needed
Here are the ingredients you’ll need to make this pickled onion recipe:
- onion: I love the flavor of red onions, but you can use white or yellow onions if you prefer!
- water: A little water helps to tone everything down just enough to achieve the perfect balance of flavours.
- Apple cider vinegar: The sweetness of the apple cider vinegar complements the flavor of the red onion, but if you have white, rice, or even red wine vinegar on hand, feel free to use them.
- Maple sugar: A little natural sweetness helps offset the sourness of the other ingredients.
- Salt: Enhances the flavor of pickling mixtures.
Variety
- let them Garlic. Thinly slice a few cloves and add them to the mixture to give your onions a garlicky flavor.
- Make them spicy. Add a little heat with peppercorns or freshly crushed black pepper, red pepper flakes, or even thinly sliced ​​habanero or jalapeños.

How to Make Pickled Onions
This easy pickled onion recipe takes just minutes to make! Here is a summary of the recipe. Scroll to the recipe card below for full instructions and ingredient amounts.
- To cook the pickling mixture: In a saucepan, combine water, vinegar, maple syrup, and salt. Bring to a simmer.
- With onions: Place the sliced ​​onions in a glass jar and pour the hot vinegar mixture over them. Press the onion into the vinegar with a spoon and squeeze out any air bubbles. Let cool to room temperature 20-30 minutes before serving or store in refrigerator.
Do you need to brine the onions before pickling?
No! Some people choose to soak the onions in the brine mixture before pickling, but I don’t think it’s necessary.
In theory, this step draws out extra moisture to keep the texture of the onions nice and crisp, even when they’re in the vinegar mixture. However, since we’re doing a quick pickle, there’s not much risk of the onion becoming too mushy. Might as well save time!
Can you just use vinegar pickles?
In theory, yes, but I highly recommend using the two additional ingredients listed.
The water and salt help balance the flavors, and the maple syrup counteracts the bitterness of the onion and vinegar. Without these, your pickled onions will be spicier!
Can I can These quick pickled red onions?
No! Please do not attempt to can these pickled onions. This recipe is a quick “refrigerator pickle” recipe. It is not designed for canning or tested for prolonged storage.
If you really want canned pickled red onions, I recommend finding a recipe designed just for that!

Tips and Precautions
- Thinly slice the onion. About 1/4 inch thick is almost perfect for me. Any thicker onions will take longer to fully pickle.
- A mandolin works best, but a pocket knife works too. If you have one, the easiest way to slice an onion is with a mandoline (ignore this tip if you’re afraid of mandolins). If you don’t have one, you can use a sharp knife. Just be very careful.
- You can tell those have been pickled They are pretty and tender when they turn a brighter pink. The liquid also cools down.
- Let them calm down. Bring them to room temperature before you put them in the freezer. This goes for anything hot, especially these!
- Extra pickling? You can pickle anything with it! Cucumbers, jalapeños, carrots, cabbage, you name it. In no time you’ll be marinating everything!
