In numerous cuisines, onions are an essential ingredient. Onions likely belong in any dish you enjoy making, which is probably why we purchase them in bulk rather than individually. How should we store onions to keep them as fresh as possible, given that they are used in many dishes and are purchased in larger quantities? We did the research, so you don’t have to.
It’s best to store tomatoes and onions separately. While neither should be chilled and stored in a relaxed, dry environment, each has special storage instructions. The shelf life and nutritional value of tomatoes and onions will be extended by separate storage.
Ideal Techniques For Storing Onions
Keeping fresh onions is easy as long as you know all the ideal storage techniques. Onions should be stored differently depending on whether they are whole, cut, peeled, or cooked. The freshness of whole onions can be prolonged given the right conditions, but they keep well in their skin. Onions, whether cut, peeled, or cooked, will require various storage conditions for more extended periods. There is a suitable storage strategy for you, depending on how you intend to prepare, cook, and preserve onions.
Do Onions Need To Be Refrigerated?
The refrigerator is the most viable storage option for cut onions. The onions’ bacterial growth is slowed by the cold temperature. The onion won’t prematurely brown when kept in a cold refrigerator.
To prevent the toxic smell of onions from contaminating the flavor of other foods in your refrigerator, we advise purchasing an airtight container. As a result of less exposure to bacteria and air is the leading cause of onions browning, a sealed container keeps onions fresher for longer. See our article for some great, airtight storage options for chilled onions.
Unpeeled onions are best kept out of the refrigerator. Refrigeration is not the best choice for an unpeeled onion. To stop bacteria from growing, cooling creates a moist but cold environment. Onions grow mushy and spoil quickly in this environment because they absorb too much moisture.
Where Do You Keep Onions?
Store whole onions in a dry area with a temperature of 40 to 50 degrees Fahrenheit. For the onions to stay as fresh as possible for as long as possible, this area should also be well ventilated. Both a pantry and a cellar work for this purpose in a house. Both places are typically excellent, dry, and well-ventilated for onions to last longer.

How Long Can Onions Be Kept In Storage?
The condition of the onion will determine how long it will keep in storage. If the onion has been cut or sliced, store it in the fridge in an airtight container. Cut onions that have been refrigerated will keep for 7 to 10 days because a relaxed, airtight environment is ideal for preventing bacterial growth and spoilage.
Peeling an onion involves removing its papery skin. We advise keeping peeled onions in the refrigerator. Once more, use an airtight container because it will keep the onion’s odor inside. The onion’s exposure to moisture is also decreased in an airtight container, preventing the onion from becoming soggy and rotting.
Refrigeration is not advised if you have an entire, unpeeled onion. This is due to the onion absorbing a significant amount of moisture from refrigeration. The onion will spoil more quickly if it is overly wet inside.
How Should Onions Be Stored For A Month?
There are several ways to store onions for a month or longer. Uncooked onions can benefit from the first option, which involves keeping them in a cool, dry area. The lifespan of whole onions can be increased past one month by using the proper ventilation techniques, which will be covered later.
The onion can be frozen as a second choice. Make sure the storage container is as dry as you can get it. By removing the moisture, the onion will no longer be too mushy to cook correctly in the future.
Make sure not to use plastic wrap or store onions in plastic bags if you want to keep them for a long time. The onion will spoil quickly because plastic wrap and bags restrict ventilation.
How Can I Keep Onions Fresh Longer?
Use freezing to keep onions fresh for longer than a month. For up to 8 months, onions can be stored in the freezer. It is best to freeze cooked onions because they often become too mushy to eat raw when they thaw.
If you would instead not freeze onions for later use in cooking, we advised storing them whole in an open basket, netted bag, paper bag with holes punched in it, or even pantyhose. These methods keep whole onions fresh for a month or more. So far, they are stored correctly in a relaxed, dry environment; these methods provide onions with the proper ventilation.
The Best Method For Storing Tomatoes
The Old Farmer’s Almanac suggests keeping your tomatoes in a cool, dark place away from sunshine. If your tomatoes are still green, you may arrange them in a little box with a piece of paper separating each layer. Your tomatoes will ripen more quickly if you use this strategy. I also advise avoiding putting them in the refrigerator to preserve the taste of tomatoes that were just picked.
Depending on the type they are, This is the proper way to preserve tomatoes, according to the Washington Post article, which quotes Craig LeHoullier, author of “Epic Tomatoes” and a tomato expert.
On a rack, side down. This is being done to prevent moisture from amassing around the stem and hastening the fruit’s ripening. LeHoullier concurs with Cook’s Magazine’s advice in its Tomato Primer, although there is insufficient proof to support it as the most effective storage technique.
Additionally, they stated that as long as the tomatoes are fully ripe, storing them in the refrigerator for a few days will increase their shelf life without affecting their flavor. Do not store ripe tomatoes beside other fruits that produce ethylene. Store them apart from one another without touching.
The tomatoes can be kept in a freezer if long-term storage is considered. To maintain the flavor and freshness, you can either place them whole, chop them up, or store them in an airtight bag. Always allow them to be at room temperature before using them in a recipe to regain taste.
The Importance Of Tomato Proper Storage
According to one publication in the food engineering review, the processing and storage of tomatoes and tomato-based products impact their lycopene content 10. Proper processing and storage will help maintain this advantageous carotenoid until the fruit and its associated products are consumed.
It also points out that the main lycopene degradation events greatly influence several other variables, including oxygen, heat, and light. These reactions, in turn, impact the bioactivity and bioavailability of lycopene molecules.
Reasons Why Certain Fruits & Vegetables Shouldn’t Be Stored Together
Ethylene. That is the brief response. Actually, a hormone produced by plants, ethylene influences growth, development, and stress responses. It is emitted by some plants while being sensed by others. But now, we’re primarily concerned with how it impacts fruit ripening.
Though it differs from plant to plant, ethylene is produced by almost all fruits. Additionally, you’ll discover that fruit contains more ethylene than veggies. Combining the two is typically a tiny tragedy waiting to happen.
The challenge is knowing which plants produce more ethylene and which ones are sensitive to it. You will then be able to identify the foods you must never store together.
Fruits That Produce Ethylene
The fundamentals of food storage are as follows: rotate and use up your stored food regularly, shift older goods to the front, position new ones to the back, and keep an eye out for spoiled foods. Make sure to take them off right away.
Regarding fruits and vegetables, it doesn’t necessarily have to be first in, first out, but you should be aware that each has a different shelf life. Freshness essentially vanishes when ethylene-producing foods are stored alongside ethylene-sensitive items.
Fruits Vary In Their Ethylene Sensitivity
In addition to the foods mentioned above on this list, you can store cherries, pineapples, blueberries, and grapefruit. You’ll be saving food like a pro once you understand where all that fruit belongs—in the refrigerator or on the countertop.
It’s a given that lettuce, carrots, and broccoli won’t taste as good when stored with apples, bananas, pears, plums, or peaches.
Apples lose their freshness, flowers and leafy greens wilt and degrade, while broccoli and cucumbers turn yellow in an environment with too much ethylene. No one wants it to occur. Not for the sake of wasting food or destroying your prized backyard garden harvest.
