Chop your onions, sauté or caramelize them in quantity, and separate them for later use to make keeping your onions easier. Keep in freezer-safe containers. Use ice cube trays to freeze them for convenience. Portioning is made simpler by the trays. While you’re cooking, take a few from the freezer. Use plastic wrap to prevent the onions from freezing in a single layer so that you don’t wind up with a sad face because you had to chop an onion.
When you need to prepare dinner quickly, having frozen chopped onions on hand is a terrific idea. The convenience they provide is why grocery stores sell them and charge you for it. Making your own allows you to reduce preparation time while assembling a dish.
How do You Freeze Onions?
While most varieties of onions keep rather well, some, like sweet onions, spoil quickly. Another excellent approach to keep onions from spoiling is to freeze them. Freezing is a quick technique to preserve an abundance of onions that would otherwise be allowed to spoil.
You will be completely changed the first time you want to cook dinner and realize you don’t have to chop an onion once we demonstrate our preferred method for freezing onions. It saves you so much time to get everything done for you! Let’s begin to freeze.
Freezing Onions
- Slice or chop the onions into appropriately sized pieces for upcoming recipes. Add the chopped onions inside as much air as possible from a freezer bag before sealing it.
- The refreeze of onions is poor. Only the amount of the chopped onions you ordinarily use in a recipe should be frozen in bags. To fully utilize the frozen onion pieces inside each bag, it is preferable to use multiple smaller bags instead of one large one.
- So that you may use up the oldest ones first, mark the bag with the contents and the date that you froze them.
- First, freeze the bag flat on a cookie sheet in your freezer, pressing to make it as flat as possible. This will make storage the simplest. Flat bags stack more easily in the freezer.
- After a few hours, remove the cookie sheet and place the bags in the freezer when the bags have frozen solidly.
Place in Freezer Bag
- The secret to successfully freezing onions is to thoroughly seal them in a premium bag or container that will keep any odors at bay. I prefer using freezer-grade, thicker plastic bags than all-purpose bags.
- To avoid a freezer burner, remove as much air as possible while maintaining the smallest amount of headspace.
- Additionally, you want to confirm that using your frozen onions is simple. Since you can break off frozen pieces as needed, I advise freezing them in pre-measured portions or a thin layer. By doing this, large clumps of frozen onions are avoided.
Seal and Freeze
- Seal the container, and then freeze it for up to three months. They will start to acquire off flavors if you keep them in storage for too long. They won’t spoil or be dangerous; they won’t taste as good.
- After making a large amount, I end up with several thin bags of onions. I keep these packs together in a bigger freezer bag for added security. This large bag is kept in the basement’s large freezer. I keep one of the smaller bags in my refrigerator and freezer for daily use.
Health Benefits of Onions
Rich in Antioxidant Compounds
Onions are one of the richest sources of flavonoids in our diets and contain over 25 different types. The plant compounds flavonoids, which have anti-inflammatory and antioxidant properties, are abundant in onions. When ingested frequently and appropriately, these substances may defend against long-term diseases, including cancer and diabetes.
Sulfur-containing chemicals found in onions have also been shown to have anticancer properties.

May Support Heart Health
Quercetin, one of the flavonoids found in onions, is known to have anti-inflammatory and protective actions and, along with other healthy components found in onions, may play a role in the vegetable’s heart-friendly features.
According to studies, eating onions may help reduce your heart disease risk by reducing inflammation, blood pressure, and cholesterol.
Dietary onions have been linked to increased bone density. This might result from their antioxidant qualities, which lessen oxidative stress and slow bone loss.
According to a study on the impact on peri- and postmenopausal women, eating onions frequently lowers the incidence of hip fracture. Another study on women in their middle years found that consuming onion juice increased bone density and decreased bone loss.
May Support Gut Health
The non-digestible fiber necessary to maintain intestinal health is abundant in onions. Although we cannot digest prebiotic fiber, the bacteria in our gut can use it as fuel to multiply and make short-chain fatty acids as a byproduct (SCFAs). According to research, these SCFAs are crucial for preserving the gut’s health and integrity and boosting our immune and digestion.
Antibacterial
Studies show that onions offer valuable antibacterial qualities against bacteria, including Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus, which are used in traditional medicine to treat coughs, colds, and catarrh. Furthermore, the older, preserved varieties seem to be the most effective onions. Because it can stop the growth of methicillin-resistant Staphylococcus aureus and Helicobacter pylori, it appears quercetin is useful here once more (MRSA).
Will Onions Change When Frozen?
Frozen onions will develop a different flavor over time, just like any unblanched vegetable. Their flavor will intensify the longer they are stored in the freezer. Because of this, I only freeze as many onions as I can consume in three months, or around five pounds at a time.
Onions’ texture will also alter; they will lose their crispness and become much softer. When they strike the pan, they will emit a lot of liquid, but it will rapidly evaporate. They won’t work well in salads or any other fresh foods, but they’re fantastic in prepared foods like stews, casseroles, curries, soups, and more.
Never chop or process food in a food processor too finely. If you like larger onion bits in the completed dish, freeze slices instead.
Will My Freezer Smell Like Onions?
This has never been a problem for me. Using top-notch freezer bags or airtight containers and sealing them tightly is crucial. You can double bag onions or put one bag in an airtight container before putting them in the freezer if you want to take extra precautions.
To prevent onion juices or bits from adhering to the bag’s exterior, ensure it is clean and dry.
Due to the potential residual onion stench in my freezer from leaving an open tray of onions, even for a few hours, I don’t flash freeze or use ice cube trays when freezing onions.
Can I Freeze Whole Onions?
Onions should not be frozen whole. It won’t be easy to defrost and use them. Onions should ideally be chopped before freezing. Blanching is boiling whole onions in hot water until the very center is thoroughly cooked if you are frantic to freeze them. It’s not at all practical.
What are the Best Onions to Freeze?
Every variety of onion you have. Any size onion will do. Red onions, white onions, yellow onions, shallots, green onions, and leeks may all be frozen by following these easy instructions.
If possible, freeze onions at their freshest and most flavorful. In light of this, freeze any onions you observe beginning to soften or sprout as soon as possible to prevent food waste.
How do You Avoid Tears When Chopping Onions?
Here are some suggestions for things to try:
- When cutting huge amounts, use a food processor; keep your eyes away when the lid opens.
- Since most sulfur compounds that induce tears are found at the root end, chill the onions in the fridge for 30 minutes before slicing them.
- Wear goggles for real
- To avoid breathing the vapors while chopping, light a candle.
- To get the vapors away from you, use a fan.
Is Cooking or Freezing Onions Better?
It is not advised to freeze whole onions. They’ll be challenging to thaw and use. Onions are ideally chopped before freezing. Blanching refers to boiling whole onions in hot water for 7 minutes or until the center is thoroughly cooked if you must freeze them.
What can I do with Too Many Onions?
Please keep them in the refrigerator all week and use them in casseroles, pizzas, or meat dishes. Use them to make onion soup. Pickle a few to put in tacos, burgers, and salads, among other dishes. They can also be frozen for up to six months.
Is Consuming a Lot of Onions Healthy?
Onions include anti-inflammatory, triglyceride, and cholesterol-lowering antioxidants and substances that may minimize the risk of heart disease. Additionally, their strong anti-inflammatory qualities may help lower high blood pressure and prevent blood clots.
Do You Need to Defrost Frozen Onions?
For just about any prepared application, frozen onions are ideal for soups, stews, sautéing with vegetables, etc. They don’t even need to thaw! We advise against using frozen onions in fresh dishes like salsa or potato salad since freezing alters their texture.
How do You Freeze Onions without the Smell?
Wrap raw onions twice or three times to prevent the scent from spreading when freezing—wrapping the onions in plastic food wrap before bagging is the best method to keep the fragrance inside and off. As additional layers, you may also use several layers of freezer bags.
How Should Onions be Prepared for Storage?
Be careful not to bump or bruise the onions as you spread them out in a single layer. Let them remain arranged in a single layer. The necks of the onions will gradually deteriorate as they cure, and the papery skin will thicken around the bulbs. It’s excellent if it’s warm (75–80 degrees F), dry, and windy.
Why won’t My Onions Caramelize?
Instead of sautéing your onions, consider carefully extracting flavor from them. The sugars in the onions take some time to caramelize, possibly about 45 minutes. The onions will burn if you have the heat set too high. Add your onions after setting the pan’s heat to medium-low.
Are Onions Good for Cholesterol?
Additionally, research suggests consuming onions may lower cholesterol. In one study, onions’ flavonoids helped obese individuals at risk for cardiovascular disease lower their levels of low-density lipoprotein (LDL) or “bad” cholesterol.
Conclusion
Frozen cooked onions can be used in stir-fries, soups, and stews. To preserve their flavor, ensure sure they have been blanched before using. For use in stir-fries, soups, and baked casseroles, onions can be cut into smaller pieces. Doesn’t overcook them since this could make them taste lessen. Blanching the onions will keep their flavor if you don’t like how cooked onions taste.
