Preserving Green Onion and Bulb Onions

*NOTE: Canning books recommend blanching onions prior to freezing.* 

This is how I put onions up.

This method can be used on homegrown and store bought onions. If the onions have a strong scent, you may want to double package them before freezing and/or pack into another freezer container.

Green onions - Remember to harvest only the green onion tops. Clean all the dead or dry stalks from onions; trim some of the green tips away from the stalks if they are dry, brown or soft. Rinse the green onions under cool running water. Dice cleaned onion and flash freeze same as bulb onions. Store in a food/freezer safe container.

Bulb onions - remove outer peel from onion bulbs and discard. Slice off the neck and root ends. Bulb onions should be firm and free of imperfections completely through the center. Rinse the onion bulb under cool running water and pat dry. On a cutting board, dice the onion and spread in a single layer onto a cookie sheet; lay in the freezer until frozen.

Remove frozen onions from cookie sheet and store in a food/freezer-safe container.

Be sure to label and date all foods you put up.


  1. Thank you for letting me know that you can freeze onions. I thought you could only dry them. thanks!

  2. You're welcome. Glad this helped you!

  3. Thanks for this! I have a load of green onions and was wondering what the heck I was going to do with them all. I know - should have thought of that before I planted them, but I didn't expect so many :) Thanks again.

  4. You're welcome! You can also dehydrate onions, and even make onion powder with them.
