It’s harvest time! It as been amazing to think about what to have for dinner and then just head out to the garden to pick some fresh zucchini, carrots, broccoli, etc.

I can easily throw together a few ingredients to make a wonderful healthy meal like paleo meatballs with some zucchini noodles, my favorite minestrone soup, or some tomato pie. Yum!

One of the goals on our little homestead is to preserve a lot of food so we can enjoy it all year long! Also, to become more self reliant and save a ton of money on food!

Organic fruits and vegetables aren’t usually cheap, so growing your own is such a relief. That rhymed… so I’m sorry :).

If you have ever grown squash you know that at a certain point it seems like you have it coming out of your ears.

Eventually, after eating it for breakfast, lunch, dinner, and even dessert you’re a little over it!

Well, freezing some of your harvest can help you enjoy it throughout the year rather that just a month or so when you have an abundance of zucchini during the summer! Hello saving money!

Can you freeze fresh zucchini?

You can freeze squash without blanching, but you have to use it within 4-6 weeks or else it may turn bitter. So if you know you are going to be eating it rather quickly you can.

Do you have to blanch zucchini or other vegetables before freezing?

Technically no (see note above), but zucchini that has been blanch will keep better, hold its texture better, and will keep it’s flavor better.

Plus, blanching can help retain vitamins (source). Freezing squash that has been blanched will last up to 12 months.

Can you freeze shredded zucchini?

Yes! Shred zucchini in a food processor (I love this one) or with a cheese grater.

Separate into freezer bags – I usually like to freeze one to two cups at a time. Than freeze flat (to save storage space).

Since it is not blanched, you should eat frozen shredded zucchini within 4-6 weeks.

You can even do this with zoodles.

How do you use frozen zucchini?

Frozen zucchini is ideal for soup, stews, and sauces. You can even use them in a veggie loaded smoothie (sounds weird, but you really can’t even tell it’s there). Just add it in the dish frozen, you do not need to thaw it beforehand. 

The high moisture content in zucchini doesn’t make it the ideal veggie for a side dish, raw, or in a stir fry. That should be left to the raw zucchini.

Pro Tips:

  • Cut the zucchini in different shapes depending on how you want to use them. Slice them in circles, chunks, or longer thinner pieces.
  • Don’t add salt! Adding salt to the zucchini can leave you with a mushy texture when you go to reheat it.
  • Replace the ice as needed. Adding the blanched squash will melt the ice and if you are freezing a lot you may have to replace the ice more than once.
  • Line your cookie sheets with silicon baking makes to make it easy to get them off without sticking.
  • Freeze them on the cookie sheets before placing them into the freezer bags so you don’t wined up with a giant block.
  • You can do this process with zucchini or summer squash.

  1. Thanks for taking pictures of each step of the process. I’m definitely going to have to freeze some of my squash this year since I can’t keep up with this years harvest.

  2. I have froze summer squash grated for sweet breads but never froze them sliced for soups and pan frying, I am going to try it this year. My garden is bursting with squash right now! I have a couple sliced and spritzed with olive oil and sea salt in the dehydrator to eat as vegetable chips right now. That is another way I have found to use them up and not let them go to waste.

    1. Do you still blanche when grating squash? I have an abundance coming up and was so excited to see that you can freeze! Thanks!
