Can You Freeze Onions?

Freezing onions provides an excellent way to stock your kitchen, save time and money as well as extend the shelf life of your onions. Whether you have red onions, white onions, or sweet onions, frying and freezing them is a great way to save time and money.

Freshly fried onions store quite well, especially when freeze-dried. In addition, these onions contain a high moisture content, which makes them ideal for freezing. Stashed in ice cube trays, frozen fried onions can go a very long time without going bad.

How Long Do Fried Onions Last in the Freezer?

You can store fried onions in the freezer for a lifetime. Just make sure to store them in airtight containers or resealable bags immediately after cooking and cooling down. If left to stay at room temperature for long periods after cooking, they may harbor harmful bacteria.

That said, it is generally recommended for frozen vegetables to be eaten within 8 months for the best quality. Once frozen solid, transfer them from the ice cube trays into a storage bag and then put them in the freezer.

Alternatively, if you do not want to freeze onions, they can be made 2 to 3 days in advance and stored in zip lock backs in the fridge until you are ready to use them.

Why Freeze Fried Onions?

To Avoid Food Waste

Freezing fried onions helps you avoid food waste. If, for instance, you fry more onions than you need, freezing provides a great way to preserve them to use later.

To Save Money

Wasting food is akin to wasting money. Oftentimes, it is cheaper to buy onions in bulk than singletons. So freeze the extras and spend less money.

For Convenience

Chopped onions that have been fried are often more convenient to use than fresh ones since they are recipe-ready. Freezing fried onions is ideal for having your onions on hand when you need only a small amount for a recipe. In addition, they provide a quick way to add flavor, fiber, and nutrients to your recipes.

What You’ll Need

Select fully mature onions and peel off the outer papery skin. Scrub the onion clean with a vegetable brush under cold water.

Step 2: Chop Into the Desired Size

Chopped or sliced onions are quite universal for a lot of recipes. Ensure to slice your fresh onions into thin layers. This really helps with the crunch. Onions that are too thick will turn into onion rings, which, although delicious, are not fried onions. To slice onions:

  • Sit outside in an area with a flowing breeze to protect your eyes from the onion sting that causes you to cry a river.
  • Peel the onions and place them on a chopping board.
  • Slice the onions thinly
  • Place the diced onions on a plate

Alternatively, you can throw them into a food processor for some grinding or mincing. To decide whether to chop, slice or mince your onions, think about what you use them for most often and then chop or slice accordingly.

Step 3: Fry

  • Take a large pot, like a soup pot, and heat. ( A large pot works well as it reduces spattering.)
  • Fill the pan to about 1-2 inches deep with your preferred frying oil. (For best outcomes, choose an oil with a neutral flavor and a high smoke point)
  • Heat the oil to 350 degrees over medium heat.
  • Start frying your onions in small batches until they turn golden brown. (make sure to stir every now and then until they soften)
  • Remove the properly fried onions from the oil and place them on a paper towel to drain the excess oil.
  • Repeat the above steps until all onions are fried. Add salt to taste and mix the onions slightly when they are all fried.

Properly cooked onions will last in the refrigerator for 3 to 5 days. To further extend the shelf life of your cooked onions, consider freezing them.

How to Store Fried Onions?

After frying your onions, wait for them to cool down to room temperature. This step is crucial as it helps prevent condensation in the container during freezing.

  • Place them in ziplock bags in a thin layer. The onions will freeze best when frozen as individually as possible.
  • Label the freezer bags or containers with the freezing date.
  • Place the packages flat in the freezer. This helps the fried onions to free faster. It also makes it easier to break off sections as needed.
