With a crisp juicy crunch and powerful burst of flavor in every bite, onions bring a lot to the table. From a nutrition standpoint alone, onions provide a healthy dose of vitamins B and C in addition to dietary fiber and protein with a low amount of calories. From garnishes to added flavor, freshly sliced onions can also help to lower blood pressure. Once an onion has been sliced, though, a virtual timer has begun to mark its inevitable expiration. Proper storage can ensure that it remains as fresh as possible to the very last bite.

Step 1

Line a baking sheet with wax or parchment paper to cover the entire surface.

Step 2

Place the onion slices onto the paper so that none of them are touching.

Step 3

Set the baking sheet in the freezer, making sure it remains level so that onions do not slide off or bump into each other.

Step 4

Allow the onions to freeze for 15 to 20 minutes. This helps to keep them from sticking to each other when they are stored long term.

Step 5

Take the baking sheet out of the freezer and transfer the onion slices into freezer bags.

Step 6

Mark the date on the bag with a pen or marker and place it into the freezer.
