In this brief guide, we are going to answer the question “What is the best way to store chopped onions” with an in-depth analysis of the best way to store chopped onions. Moreover, we are going to discuss tips to properly store chopped onions.

So without much ado, let’s dive in and figure out more about it.

What is the best way to store chopped onions?

The best way to store chopped onions is to put them in a resealable plastic zipper bag or air-tight container and store them in the fridge at or below 40 degrees Fahrenheit. Within 2 hours they are peeled and chopped. Thus, chopped onions should be stored in air-tight bags or containers in the refrigerator to keep them from inducing smell in other foods.

So what you gotta do is to place the chopped onion in a resealable plastic zipper bag and press the air out before sealing. The less air you leave in the plastic bag, the longer the leftover chopped onions will last, so get as much air out as possible.

Mark the container with the date of that day. The chopped onions that are refrigerated properly stay good for about 7-10 days, but always inspect the chilled onion for contamination and discoloration before using it to ensure optimum freshness.

It is worth mentioning that chopped onions last for about 2 hours when kept at room temperature. Chopped onions will not only lose their moisture over time but can also become the favorite spot for many bacteria and other microbes to grow upon. Therefore you should store chopped onions in the fridge properly.

Long term storage of chopped onions

Freezing

In case you are not going to devour chopped onion within a few days then you go ahead and freeze it. The cold temperature of the freezer stops bacterial growth on chopped onion, preserving its quality for a long time.

Chopped onion lasts for about 8 months when stored in the freezer in plastic freezer bags.

You can either thaw your frozen chopped onions by leaving them in the fridge or if you are in a hurry, you can thaw them by immersing the plastic zipper bag having frozen onions in a bowl of cold water.

You can also add the frozen chopped onions directly to the pan without thawing them first (in case you are going to use it in a recipe) but do not forget to adjust the cooking time according to the frozen chopped onions.

Canning

Canning can also prolong the shelf life of your onions. So what you gotta do is to place the onion slices in a colander and sprinkle them with canning salt. Wait an hour before rinsing the onions. In a large pot, bring the vinegar and sugar to a boil before adding the onions.

After the mixture re-boils, reduce to a simmer for ten minutes before turning off the heat. Fill Mason jars halfway with the onion mixture. Allow for a 12-inch headspace. Gently press the onions with a blunt spoon to remove any air bubbles.

Screw the lids and rings on and tighten them. Place the jars in the pressure canner using a jar lifter. At 1,000 feet, the processing time is roughly ten minutes; use a canning chart to adjust processing time for your altitude. Allow the jars to cool for a day before storing them in a dark, cold place.

Tips to properly store chopped onion

  1. You should always store your chopped onions at 40 degrees Fahrenheit or below. Bacterial growth takes place at a faster pace between the temperature of 40 and 140 degrees Fahrenheit, therefore it is always advised to store your chopped onions at a lower temperature to preserve their freshness for a long time.  
  1. It is a good practice to store chopped onion on one of the shelves of the refrigerator rather than the door as there is a lot of temperature fluctuation at the door of the fridge that can mess up the quality of chopped onion.
  1. You should never leave chopped onions for more than 2 hours at room temperature as bacterial growth takes place at a faster pace between the temperature of 40 and 140 degrees Fahrenheit, therefore there are greater chances of the chopped onions being already contaminated with bacteria when left out for more than 2 hours.
  1. Moreover, if the temperature of the surroundings is about 90 degrees Fahrenheit, then the process of spoilage takes place at a faster pace and it is recommended to discard chopped onions that are left out in the open for more than an hour at 90 degrees Fahrenheit.
