Two weeks in a row, I received green onions in my farm basket. LOTS of green onions. This tip is a hybrid of something I saw on another blog (that I failed to save, so I unfortunately can’t give credit) and my own tweaks.
Here is a pic to show just how many onions I’m talking about, lol
I chopped the entire bunch, and spread them out in a single layer, on my cookie sheet (it’s not dirty, it’s just well-loved, lol). They COVERED the whole sheet. I placed the onions into the freezer.
Once they were completely frozen, I broke them apart wherever they stuck together, and poured them into a large water bottle with a flip-top lid.
Now I can easily shake out as many onions as I need, into whatever I am cooking. These wouldn’t be great to go on top of a salad or anything raw, of course, but into a stir-fry or soup, they will be just fine!

Great idea!
