We have a lot of zucchini this time of year. Sometimes the ones that are hidden in the garden grow really big, and aren't as flavorful.

If you have too much zucchini, shred them in the food processor and freeze for the future. I freeze mine in half cup portions. You can use them in baking or cooking. They can also be substituted for pumpkin purée or applesauce.

It will be watery when thawed, so drain it and save the drained liquid for use in recipes.

This time of the year zucchini is all around. You may find that you have too much of it. You may also have some zucchini that was hidden and grew too big to be flavorful. You dont have to waste any of it!

In July or August it is best to keep your car doors locked or you are apt to end up with a backseat full of oversized zucchini. My solution is both simple and thrifty.


For the giant ones, de-seed (using a spoon), peel if necessary, shred with a food processor, and store in two cup amounts.

When freezing zucchini, do l shredded it after I cook it and then freeze it?

By susan burnette from lN


June 29, 20100 found this helpful

Hi Susan! I have had good luck with simply shredding it, measuring it out into 4 cup increments, and freezing it. I have noticed that when I thaw it to use in baking bread, the quantity is about half of the freshly shredded variety.


I guess that is from the liquid portion freezing and thawing. I recently read that you should squeeze out the liquid before freezing. I think I will give that a try this year. Good luck!

If you plan to use the shredded zucchini in bread, you don't cook it anyway. You just leave it raw. I shred mine, put in freezer without any other prep. Sometimes it gets a little too "soupy" when frozen so you might want to drain some of the moisture off so your bread turns out ok.

I just shred it raw and put it in freezer bags. Once thawed I usually drain and squeeze out excess water.

I, too, just shred and freeze in a freezer bag. For fried or baked zucchini, I slice it and bread it, freeze on a cookie sheet then put into a bag and put into the freezer. I do the same with my okra.

I wouldn't. Wash, slice, blanch for 3 minutes, place in ice water for 5 minutes, drain well to remove as much water as possible, place in freezer bags and freeze.

I wonder if you could freeze this whole if you freeze with dry ice? Alton Brown once did that with whole strawberries on his show and he said they froze so fast that they didn't get all mushy like regular freezing. I have no idea what dry ice costs, but it might be worth trying out. Same goes for whole peaches, blueberries. You could buy a little of several things and while you have the dry ice, freeze a variety of things. It only takes a couple of minutes. Then thaw the next day and see how they come out.

Can I freeze marrows?

By Neil


September 9, 20110 found this helpful

Are you referring to the vegetable marrows that are grown in England. Here in the States we have a smaller version called Zucchini. It does not freeze well as it contains a lot of water. Maybe someone will know of another method of preserving it.

When freezing zucchini what do you have to do so it doesn't turn watery when thawed out?

By Vicki W


July 17, 20120 found this helpful

Unfortunately, squash is a high percentage water, so it will always be watery when thawed. This is why most recipes for zucchini breads, muffins, cakes, etc, are very thick--to allow the excess water from the zucchini to thin the batter. Personally, when I freeze grated zucchini for breads, I always use its water in the recipe (I usually add powdered milk to it, for the liquid).
