Storing chopped onion in Freezer and in fridge

I was wondering whether one can store chopped onion in the fridge and freezer. Well, I know i can store in the fridge, but for how long?

Also, I make a lot of persian recipes, which call for stews with browned onions (fried to the point they're golden brown). Can I store that in the freezer as well? I've seen a lot of persian moms/grannies do it.

  1. I don't see why you couldn't store chopped onions in the freezer, since one can buy frozen chopped onions - I do think they tend to be a little watery though.

      And what about fridge?

        I've kept chopped onions in the fridge for up to a week. It's a little iffy to eat them raw at that point since they lose their crunch and punch, but they're perfectly acceptable for cooking since you'll want them to soften and mellow out anyway.

    2. When I had a need for bulk amounts of onion/celery/green pepper, I'd buy 'em real cheap in September/October, chop, feeeze on trays, then break into bags. If you freeze them directly in a large bag, you get a frozen lump of veg. Freezing on a tray gives an IQF effect and is easier.
      I can then use it throughout the winter.
      They ain't much good where fresh veggies are a must, but they work great in soups, stews, and some sauces.
      I've had them for almost a year with good results, long as they are stored alright. I don't have experience with sauteed onions, but I'm assuming it'd be fine.

      1. They lose they're umf in the fridge after being cut up--maybe a couple days? I chop them and store them in the freezer all the time. A couple weeks. I only use it for cooking and it works very well for me. So convenient.

        1. Do it all the time - freeze in bag or container, generally used within a month but would keep longer. They cook way faster, straight from frozen, than fresh-chopped, since freezing breaks down cell walls. Sauteed onions at all levels of brown-ness freeze fine too, for months. Just pry off whatever you need, and return package to freezer. The fat from frying keeps them from being as hard as fresh frozen onion. You can refrigerate chopped onions for many days, depending on type and freshness of onion, and how finely chopped - when they turn too mushy they start to smell off, too - it's very obvious.

          1. My Iranian mom has fried onions in the freezer all the time, for use in stews and things where the texture won't matter. She freezes them in 1/2 cup or so bunches in an airtight container.
