How To Make (step-by-step) – Quick-Pickled Onions
Peel the white onions and slice them into rings or half-moons with a thinly sharp knife, depending on your preference.
Place the sliced onions in a clean, sterilized jar with the black pepper, salt, and sugar.
Using a kettle or a small saucepan, heat water to boiling.
Add vinegar to the jar with the onions, and carefully pour the hot water, ensuring the onions are fully submerged.
Close the jar with the lid and give a good shake to mix.
Let it cool down upside down for a couple of hours at room temperature and refrigerate.
For best results, let the onions pickle for 24 hours.
Tips For Making Perfect Pickled Onions
- Larger onion pieces take longer to pickle and have a more pronounced flavor.
If you prefer a milder pickle, make thin slices.
- Balance your flavors.
Adjust the salt, sugar, and vinegar to your liking. Some people prefer a sweeter pickle, while others like theirs extra tangy.
- Use a 1:1 ratio of vinegar to water for ideal acidity.
- Let it cool upside down so the jar seals tightly, and you can store the onions for much longer.
Just be careful not to create air bubbles.
- Store in the fridge to maintain crisp texture. Don’t store at room temp!
- Patience is key.
While it may be tempting to dive into your pickled onions immediately, they are best to marinate for at least 24 hours.
Ideas For Serving

Here are some creative ideas for incorporating them into your meals:
- Add a zingy twist to your favorite sandwiches, burgers, or hot dogs by layering pickled white onions on top.

Storage – How Long Do Refrigerator Pickled Onions Last?
Store your pickled onions in the refrigerator for about 2-3 weeks if the jar is open.
Make sure the onions are always submerged in the pickling liquid.
Unopened jars of pickled white onions keep in the refrigerator for 2-4 months.
Are pickled white onions the same as red onions?
Pickled white onions and pickled red onions have slightly different flavors.
White onions have a milder taste and a crisp texture compared to red onions, which are sweeter and softer when pickled.
Do you have to soak white onions in salt before pickling?
This step is optional.
Soaking onions in salt can help draw out excess moisture and enhance their crunchiness.
For a crunchier texture, soak the onions in salt water for 30 minutes before pickling.
What variety of onions is best for pickling?
White onions are ideal for pickling due to their mild flavor and firm texture.
However, to create a unique flavor, you can experiment with other onion varieties, such as red onions (also known as purple or blue onions) or shallots.
Can I reuse the pickling brine?
You can reuse the pickling mixture for future batches of pickled vegetables.
Simply strain the brine to remove any onion remnants and store it in a clean, airtight container in the refrigerator.
The flavor will definitely change, so you may need to adjust some things, like vinegar or salt.
I like to use pickling liquids (especially onion) for an easy vinaigrette.

Things To Remember When Pickling Vegetables And Fruits
There are a few key points to keep in mind when pickling:
- Always use fresh produce: The fresher your veggies or fruits, the better your pickles will be.
