Home canning and pickling are a great way to make your garden's bounty last through the rest of the year. Whether you've got way too many onions or just really enjoy the pickled variety, you might be wondering how long they will stay good for. After all, food safety is paramount when it comes to home-canned goods. When done properly, your unopened home-canned pickled onions are shelf-stable for one year. Although some university extension programs say that with proper storage, you can stretch that up to two years for lower acidity foods -- which onions are -- the USDA gives a 12-month maximum for anything canned at home.
Of course, once that jar of pickled onions has been opened, it will need to be refrigerated. And while it might be tempting to keep them cold until they're used up, the USDA gives all opened home-canned goods a pretty short window: Just three to four days in the fridge.
As with all home-canned foods, you will want to maximize your pickled onion's shelf life. Do so by following all canning instructions to a T. And always use a recipe that has been scientifically tested and approved. Failure to do so could lead to serious illness, including botulism, which can easily go undetected in improperly canned foods and can be fatal. Additionally, any canned food that smells or appears questionable should be thrown out immediately without tasting. Although some hissing is normal when opening goods canned under pressure, always toss a jar that spurts or hisses excessively.
Temperature, light, and humidity can all affect how long your home-canned pickled onions last, so be sure to store them somewhere that is dark and dry with a cool, even temperature. Fluctuations that can lead to freezing or overheating will cause them to go bad prematurely, so choose your storage location carefully. Always refrigerate pickled onions right away after opening, preferably with an opened-on date so that you know when their time in the fridge is up (just as they should be dated when they are first canned).
Putting Those Pickled Onions To Use
Pickling works well for white, yellow, and red onions alike. Which type of onions you choose to pickle will naturally affect how they taste and what you use them for. And if you're not up for the canning process, they can even be pickled and stored in the refrigerator -- though, in this case, you'll want to use them up within a couple of weeks.
Pickled red onions are excellent on salads, sandwiches, and wraps. They make awesome garnishes for roasted meats, and they're amazing in tacos and chicken quesadillas as well. Any type of pickled onion will go great in potato salad, but the red ones are best for a fun burst of color. Pickled yellow or white onions will also add a delicious tang to your BBQ, or sub them out for pearl onions in a tasty co*cktail. With so many uses, it shouldn't be hard to gobble up those home-canned pickled onions before they expire. Before you know it, it'll be time to make another batch.
If using the quick method, pickled onions will last up to one month in the fridge. If you have used the slow method, store the onions in the fridge for up to two months.

How long do canned pickles last? If the jars are properly heat-processed, both homemade and commercially sealed pickles can sit unopened at room temperature for years, says Julie Laing, author of The Complete Guide to Pickling. But eating them sooner will ensure the best texture and flavor.
Pickled onions last longer than fresh onions due to the preservation process involved in pickling. This process creates an acidic environment that inhibits the growth of spoilage-causing microorganisms, thereby extending the shelf life of pickled onions.
The hot liquid kills microorganisms on the food, including any probiotic “good guys.” The heat also destroys any enzymes in the vegetables. Acetic acid in the vinegar provides an environment that turns the vegetables sour. The acid environment also discourages spoilage organisms from growing back.
Unopened jars of pickled onions should last around one to two years past their printed date when stored properly. Once a jar is opened, the pickled onions should be used within two to three months if kept in the fridge.
Like all perishable foods, they should be stored in the refrigerator once opened. Assuming nothing has gotten into the jar to cause your pickles to go bad, they should last up to three months in the coldest part of your fridge (i.e. towards the back).
The question; "Are pickled onions good for you?" has a simple answer; yes. ... But pickled onions are very different, and it is the pickling process that changes the health aspect of an onion from, "eat all you want," to "eat in moderation," because too much pickled onion can be bad for you.
Making sure enough vinegar is added to the cucumbers is important to make safe pickles; Clostridium botulinum can grow in improperly canned, pickled foods with a pH higher than 4.6. It is critical to use scientifically tested recipes for making pickles to ensure their safety.
Are pickled onions high risk food? No. Foods stored in an acidic environment are generally safe from contamination as germs cannot thrive in such conditions. Pickled foods are high in acidity.
For canning, a 5% acidity level is required for safety reasons. The recipe requiring 5% vinegar level is because the produce that is being used in the recipe is low acid food. Any less than a 5% level will not destroy the dangerous bacteria that cause botulism.
Pack the onions into clean, sterilized jars. Pour over the hot vinegar mixture to fill the jars, and check there are no air pockets. Seal the jars and leave to cool. The onions will be ready to eat after about 1 month or better if kept for 2.
How long does pickling vinegar last? Generally, manufacturers place a best-before date of between 1 and 3 years from production on pickling vinegars. This is often just for guidance to ensure you use the vinegar when it's at its best and is dependent on a successful vacuum seal on the jar.
Pro tip, if you eat the onions quickly, you can reuse the brine. Add more sliced red onions to the mixture and start again. You can also try pickling other sturdy vegetables like sliced radishes, carrots, or small cauliflower florets. If the brine is cloudy or has a bad odor, discard and start with a fresh batch.
