Onions are always helpful to have on hand. They are one of the most versatile culinary companions, regardless of the season. We purchase them in abundance at the grocery store, stocking up on those large mesh bags bursting with various types of onions. However, because their signs of deterioration are less evident than those of other vegetables, you may be storing onions well past their prime without realizing it. So, what is the best way to keep onions fresh?
Learn precisely how to store onions and how long they will last, contingent on the conditions of their storage.
How Long Do Whole Onions Last?
Onions prefer air, dry climates, and mild temperatures in general. Maintaining optimal storage conditions will significantly extend their shelf life.
Store In A Cool, Dry Place
The optimal temperature to preserve onions is between 45 and 55 degrees. According to him, onions should be stored in a cold, dry location, such as a cellar, pantry, or garage. While you can keep onions in the refrigerator whole, Yee warns that this can cause them to convert starch to sugar, resulting in limp or soggy onions.
Reduce Moisture
Before storage, remove onions from any plastic grocery bag and avoid produce that emanates moisture, such as potatoes. Some professors explain, “If you leave whole onions in a shopping bag without air circulation, it will reduce shelf life by retaining moisture and promoting the growth of spoilage microbes like mold.” “Onions can sprout when exposed to high levels of moisture.” If the bag you bought or kept the onions in from the store is impermeable, transfer them to a mesh bag or airtight container.
Keep Onions Away From Light.
In addition to locating a calm, dry, and well-ventilated area, You should keep onions out of direct sunlight. “Heat generated by sunlight or other means can encourage the growth of spoiled microbes such as mold,” according to Cooper.
How To Store A Cut Onion?
The storage location and method for onions depend on whether they are whole or chopped. In contrast to entire onions, you should keep cut onions in the refrigerator in a plastic bag or airtight container.
“It is important to note that pears, apples, and celery will absorb onion odors if kept near them, so ensuring the onions are tightly packed can help prevent this,” Cooper explains. “Onions themselves can also neutralize apple and pear odors.”
How To Freeze Onions?
Cooper advises against freezing whole onions but says diced, or you can freeze sliced onions. To accomplish this, diced or you should place chopped onions in a freezer container with as little air as possible.
Cooper suggests using frozen onions for cooked dishes rather than defrosting and consuming them fresh in a salad or sandwich because freezing alters the texture of the onion.
How To Store Sweet Onions?
Sweet onions such as Vidalia, Walla Walla, and Maui contain more water than storage onions, causing them to perish more rapidly. In this instance, preserving them in the refrigerator extends their shelf life.
The National Onion Association suggests packaging whole, unpeeled onions in paper towels and storing them in the fridge.
How To Store Green Onions (Scallions)?
There are three distinct methods for storing green onions, also known as scallions. The initial option is to keep them in a container on your windowsill. You need just enough water to cover the roots in the container.

You could also place the jar in the refrigerator with the bag on top, where You will keep it for two to three weeks.
The third method of storing green scallions involves removing the roots. You may also need to halve the green onions to accommodate them in a zipper bag. Wrap them in moist paper towels, place them in a bag, and leave them uncovered (unsealed) in the refrigerator. They should last 1-2 weeks in this condition.
How Long Onions Last?
The longevity of onions is dependent on their keeping environments. According to Cooper, sliced onions will last 10 to 14 days in the refrigerator, and sliced onions will last 7 to 10 days. Cooper says that while there are better locations to store whole onions than the fridge, they will typically last two months.
“If stored in an area of your home that is refreshing, with adequate air circulation, and dry, entirety onions can have a shelf life of three months, and sometimes up to six months, provided they are dry, firm, in skins intact, and not sprouting,” according to her.
If stored in a freezer at or below zero degrees Fahrenheit for eight months, you should ingest frozen onions.
How Do You Keep Onions From Rotting?
It’s all about storage: Keep onions out of direct sunlight and in a cold, dry, well-ventilated area. Any environment that promotes moisture will cause onion to deteriorate.
Remember that onions have likely spent some time in transit before reaching the produce section. If you’ve ever sliced into an onion and found it rotten despite having stored it correctly, the decay likely resulted from improper storage conditions or may have originated in the soil.
How Do You Store Onions For A Month?
Under ideal storage conditions—repeat “cool, dry, and dark” five times!—most onions should last at least one month.
Consider enveloping each bulb of more perishable onions, such as spring or sweet onions, in paper towels to absorb excess moisture, which can alter flavor and texture and hasten spoilage.
How To Tell If An Onion Is Bad Or Spoiled?
There are three ways to identify spoiled onions: color, texture, and odor. Onions that become bad might acquire dark spots that will ultimately develop mold. It would help if you also avoided scallions that have sprouted, as this indicates that they are about to spoil.
You can also feel your scallions to determine their freshness. Onions that have soft or mushy areas are becoming spoiled.
Who could forget the smell test? As shallots deteriorate, their aroma will inevitably change. Of course, some people don’t like the fragrance of raw onions, so let’s say that if your onions start to smell like anything other than onion, it’s probably time to replace them.
To maintain the freshness of scallions, proper storage techniques are required. It is essential to store them in a quiet, dry, and well-ventilated location, such as a pantry or mesh bag, away from moisture and direct sunlight. By separating them to prevent premature deterioration, onions retain their quality for extended periods.
