Can you freeze onions or will they last chopped in a container in the refrigerator for a week?
By Linda from Brooklyn, NY
I always chop up two onions and put 1/2 cup at a time in baggies, then put them in a ziploc type container and freeze them. I do the same with green and red peppers. (11/21/2009)
I chop them, lay them on a cookie sheet, and put the cookie sheet in the freezer. Once they're frozen, I transfer them to a zip-top bag and store them in the freezer (sometimes I use canning jars with plastic lids. I'm not sure how long they'd last, but I've kept them for a few months in there. I do the same with celery and bell peppers. (11/21/2009)
When I used the frozen onions they are always soggy so I don't know if there is a way round that - anyone know? (11/22/2009)
tiesgl definitely freezes them correctly and, yes, they will be okay chopped in the refrigerator for up to a week fresh but not for a week after freezing. (11/23/2009)
I am a big fan of Food Network ,esp. Alton brown he explains the chemical aspect of a lot of cooking; why something does or does not work. Onions have a lot of water in them by nature. You need to have anything that you freeze to be as dry as possible.
Alton used a pan to spread his veggies on and placed in the fridge to dry. Once dry they were placed in freezer bags with as much air removed as possible. He used a straw to suck out the air, I don't know.
Yes you can freeze onions. When I make spaghetti sauce, I chop fine one whole onion in the food processor. I use about half and put the rest in a sandwich bag and throw it in the freezer. When I make spaghetti sauce again I have onions already chopped and they thaw in the hot sauce. (11/24/2009)
I always chop one whole onion and store them in a plastic container in the fridge. They stay good for a week! (11/24/2009)
