The method of keeping onions fresh exists, just find it and put it into practice. It takes very little.

Are onions at home short-lived and sometimes you have to throw them away because they mold? Or have they become dry and inedible, and you can’t use them anymore? Well, there are many ways to keep them fresh for a long time, here they are!

Keeping onions fresh for a long time in a black bag

If you have onions in the refrigerator or in the basket and you want to store them so that you can use them for a long time, here’s what you need to do:

  • When buying onions, make sure the skins are intact and not rotten;
  • Remove any outer skins that appear dirty;
  • Place the onions in a black bag.
  • Take 2 tablespoons of salt and put it in a paper towel;
  • Cut 4 or 5 slices of ginger and place them on top of the salt.
  • Make a square out of the napkin and wrap it around itself;
  • Attach two rubber bands to the ends.

Now place the napkin in the black bag the way you rolled it, let the air out of the bag and tie a knot. When you have carefully tied the bag shut, store it in a dry place. The spicy flavor of ginger has the ability to kill bacteria, preventing bacterial infestations in onions. Salt is a highly absorbent ingredient, so it absorbs moisture, which can cause onions to mold. The black bag blocks light penetration and thus prevents the growth of onions.

Alternative method: the transparent bag

Another way to keep them fresh for a long time is to store them in the transparent bag. Here’s how:

  • Take them and put them in a transparent bag.
  • Put two cigarettes in the bag.
  • Close the bag and store it in the refrigerator at below 23 degrees.

Fresh onions with baking soda and tea leaves

If you are still using the clear bag, here is another method to keep fresh onions for a long time:

  • Put them in a clear bag
  • Take a paper towel and spread some baking soda on it
  • Add to the bicarbonate of loose-leaf tea
  • Close the bag and store it in a ventilated and dry place at the same time.

Baking soda has an excellent absorption effect and prevents excess water from being absorbed. The tea leaves also absorb water and odors, keeping the onions dry and odor-free. In addition, they contain polyphenols that prevent the sprouting of onions.


Another safe way to keep onions fresh for a long time is to use rice. Take a plate, pour some rice and put it inside. Cover with rice and you will see that no bacteria will form because of the strong smell. Since rice is practically dry, it stays dry and fresh for a very long time. When you take them, they are still firm and intact and also full of flavor!

Store onions in jars

The jar method is also very easy as it keeps them fresh for a very long time. How to do it:

  • Take a glass jar with a stopper;
  • Put the onions in it, making sure there is no space between them.
  • Close the jar and keep it in a dry place.

They will be close together and stay intact and perfect for a long time. Again, you need to keep them in a dry place.

As you can see, you can choose your favorite infallible method of preservation and always enjoy them as you bought them, deliciously fresh!
