Q. I planted a huge garden this summer, and I’ve got a bumper crop of green onions that I can’t possible use all at once. It would be a shame to see them go bad, but I don’t know what I can do to store them over the long-term. Can you freeze green onions?
A. Yes, green onions can be frozen! There’s nothing better than the flavour of fresh picked vegetables from your own garden, but unless you live in a climate that allows you to grow all year long, there’s a short growing window for home gardens. In order to keep enjoying the fruits of your labor year-round, it’s important to preserve some of your harvest for later. Freezing is a great way to do that. With many green vegetables the recommendation is to blanch them first by placing them in boiling water, but that’s not necessary with green onions.
How to freeze green onions?
Start by choosing fresh onions with few to no blemishes. Wash them carefully, and then dry them using some paper towels. Allowing the onions to dry completely before freezing is important to help the onions keep as much of their original texture as possible after thawing. Once the green onions are cleaned and dried, it’s up to you whether you want to freeze the greens and the whites of the onions together or separately. Since many people like to use the green and white parts for different purposes, the instructions here are for freezing them separately.
Slice the onions into two parts, the white bulb and the green stalk. Beginning with the green, slice thinly into small pieces. Place the sliced pieces on a baking sheet and place it in the freezer until the slices have flash frozen, about 15-20 minutes. While waiting, slice the whites of the onions into small pieces. Place the pieces on a baking sheet, and place the baking sheet in the freezer when you take the one with the green pieces out.
To freeze the sliced onions, place the flash frozen sliced green onion in freezer bags. Smooth the freezer bags flat to remove the air, and then seal the bags. Green onions can also be frozen in freezer safe containers after being flash frozen, as the pieces won’t clump together. To thaw, remove desired quantity of green onions from the freezer and place in the fridge to thaw. Thawed onions will be softer than fresh and will lose some of their crispiness, so they may not be great for salads. However, they can be successfully added to cooked recipes including pizzas and as garnish for soups.
