How to Freeze Zucchini

If you grew even one plant of Zucchini you probably have so much you don’t know what to do with it all! I sure do!  One of the best ways to preserve Zucchini is to freeze it.  It is SUPER quick and easy to freeze and has many different uses.  You can cut it up and use it in stir fry or kabobs. or shred it and use it in Zucchini  Bread, lasagna, egg dishes and more. See all of our Zucchini recipes if you need some inspiration! This Zucchini Pizza Crust is one of our faves!

 Freezing Sliced Zucchini in 7 Steps

1.  Fill a large stockpot three quarters of the way full with water and heat to a  boil on the stove top.

You can do large amounts at once or just a few! Make sure that your pot is big enough to fit everything you are wanting to put in though!

2.  Wash the fresh zucchini with water to remove any dirt. Dry the zucchini and place on a cutting board.

This is super important! I am sure you know this, but be sure to always wash your veggies before eating! You never know what kinds of chemicals could be on them.

3. Slice the stem and the end of the zucchini off and throw away or add to your compost pile.  Slice the remaining zucchini into 1/4 – 1/2-inch pieces for  freezing.

4.  Prepare a large bowl with ice water to cool the zucchini after it is blanched in the boiling water.

I just filled my bowl with cold tap water and about 20 ice cubes. It is important to do this before putting the zucchini in the hot water so that the water has enough time to get extra chilly!

5.  Put the zucchini slices in the boiling water for up to three minutes to blanch. 

Start timing once the water has returned to a boil. Blanching the zucchini stops enzyme production,  this helps the zucchini maintain its taste and color when frozen.

6.  Remove the zucchini from the boiling water and quickly put it into the ice water.  

Keep the zucchini in the cold water for three minutes (add ice if necessary). Strain off the water and allow it to drain for five minutes to remove excess water.

7.  Put the zucchini into freezer bags or vacuum seal bags for storage.

Remove as much air from the bag before sealing it. This helps keep  ice crystals from forming on your zucchini.  Seal the bag and label with the contents and date you froze the zucchini, so you can identify it in the freezer later!

Grating Zucchini

1.  Wash and cut the zucchini in half lengthwise and remove the seeds.  (I usually use my large zucchinis to shred.)

I remove the seeds just with a spoon! It is so easy to scoop out the seed layer! You’ll be done in seconds.

2.  Use a hand grater, food processor or Kitchen Aid grating attachment to shred the zucchini. 

Grating zucchini with the skin on preserves its crunch when frozen. I just used my hand grater and I was done in less than 3 minutes with an entire, huge zucchini!

You may also want to steam or blanch grated zucchini before freezing. (see above)  I then measure the shredded zucchini into a freezer bag.  I like to measure it according to what most of my recipes call for ie Zucchini bread 2 cups.  Grated zucchini can be added to quick breads, egg dishes, lasagna and many other recipes.

That Is It

That is all! Follow those quick and easy steps and you will have all your excess zucchini frozen in NO time at all! Good luck!

    Another great way I saw was to add a little sugar or very carefully, add a little salt to the grated zucchini to draw out excess water. Drain well. Measure into a 1 C measure (or whatever sizes you want) and turn upside down on a parchment lined baking sheet. Freeze. You can wrap individually and put a bunch in gallon bags or just put them into bags. Zucchini pucks.

    My question is: do you get a quality product after freezing?
    I have always heard the zucchini came out horrible after freezing. I don’t want to put in all the work & fill up my freezer, if I’m just going to have to throw it all away in the end. Better it just give it away (we’ve got a garden).
    I do make a lot of stir-fry, and have been making ‘zoodles’ with my julienne tool.

      I have a garden too, and love my zucchini. I hate to drop the bomb, but it is not the same once frozen. What we do is eat all the fresh cooked dishes while it’s growing and can, freeze and shred for the
      freezer at same time. Canned and frozen slicbrees can be used in casseroles. Shredded can be used
      for bread and cookies (very watery, squeeze out like frozen spinach) I add the shredded also to
      stir frys, mashed potatoes and eggs for color. Happy Gardening!!!!

      I just shred it and put it in the bag pre-measured for zuchinni. Works great. Everyone asks for the recipe.

  • Betty

    Thank you. We love zucchini and usually have a lot from our garden.

  • MEAl5

    I love it because it’s healthy!

  • Linda

    When you grate zucchini for freezing, when you measure out the grated product for a recipe do you add any extra to take account when thawed and squeeze out the excess liquid for your recipe do your measure the thawed product or add to your recipe even if the zuchunni is less than what the recipe calls for. How do you do this?????? I’ve always wondered about this topic. HELP

    • Glenda G

      I usually grate and measure 2 cups per bag. Just pour off excess fluid when thawed and it’s the correct amount for zucchini bread or zucchini appetizers I always write 2 cups on bag and date it. It is great to have later on . Sliced is good in casseroles.

  • Mary lou

    I want to make zucchini boats this winter. Can I slice them down the middle and scope the seeds out and freeze.

    • Cathy Yoder

      I think if you cut into them, you may want to blanch them (boiling water for about a min) prior to freezing them. You could try a whole, uncut, zucchini as well. Just use it sooner than later, as they only last for about 3 months in the freezer (make sure you have it covered to protect from freezer burn!)
