Have any of you ever frozen raw zucchini? Do you peel it first, slice it, shred it? How have you done it? Does it turn brown if it's frozen raw?

I have frozen it...
I slice mine and prepare as if I was going to cook it ( batter, etc) then I lay them out in a single layer on to cookie sheets and freeze about an hour or so( or over night)
then bag and replace in freezer (I have used regular ziplock type freezer bags as well as vac u pacs, both work well, bu they keep longer in the vacu pac of ocourse)
In the ziplock , I used qt size bags and removed what I needed at the time to took ( I fried). The vacupac bags I portioned them inot packages of family meal size.

i think if you're going to use it soon you could do it raw, i think it will dry out faster raw, i blanched mine but it was mushy when it thawed and we didn't really care for it.

Have a sister who pre cooks it some, then freezes.

I shreded mine , and froze it in to serving sizes for muffins and fritters there was quite abit of water to it so drain well and pat dry with paper towels.

gordon food service sells frozen zuchinni, so I would say yes, just slice it and blanch it first

I shred and freeze it.
Clean it well and don't peel it.
Just cut off the ends and any bad places.

Thaw it out in a drainer.
Before you use it I lay it out on paper towels to absorb much of the water in it.

I use it in breads and cakes.

Never had any problems with it.

If you don't drain it well before using it, your recipe may be a bit too wet which may take it a little longer to bake.

This is how I prepare mine also. I just put it in Ziplock bags, portioned for the recipes I use for breads, cakes and cookies. Then I put all the small bags in another larger Ziplock to give an extra layer of protection from freezer burn. It works fine for me this way.

I freeze it...cut it in pieces for soups etc...if for breads and muffins I go ahead and shred it...just baked 3 loaves of zucchini bread and 54 muffins last night and have lots of it back in the freezer...can keep it up to a month in freezer after baked

yes I do...shredded mostly for stews and breads in the winter...
