Zucchini is one of those garden crops that can go from “this is great” to “I’m extraordinarily overwhelmed by this” in about 45 seconds.

When you’ve already made Air Fryer Zucchini Chips, Double-Chocolate Zucchini Muffins, and Fried Halloumi with Bruschetta Zoodles, it’s time to save all the extras for delicious future meals.

So just like freezing blackberriesfreezing cherriesfreezing peaches, freezing peas, freezing onions, and freezing strawberries, we’re preserving the crop in the freezer. That’s right, the freezer. No need for canning equipment or anything fancy. Check out my complete guide on how to freeze fresh produce.

Can You Freeze Zucchini?

Yes! Zucchini works really well in the freezer. And if you’re not from the states you might be searching for freezing courgettes. You’re in the right place!

The way you choose to freeze it (shredded, zoodles, slices, or whole) will depend on how you plan to use it when it has thawed.

Frozen veggies, including zucchini, are standard items of our Freezer Essentials. Add some shredded zucchini into Instant Pot Lentil Soup, or Instant Pot Turkey Chili to increase the veggie content without any fuss. 

How to choose zucchini for freezing

You’ll want to look for small to medium-sized zucchini with thin skin. When overlooked zucchini start approaching that “baseball players could use this as a bat” stage, there is nothing you can do to salvage that. Compost it or offer it to a friend with chickens (like me!).

IS IT OK TO FREEZE Zucchini WITHOUT BLANCHING?

Yes. And no. It’s heavily debated in preserving circles (a truly raucous group…) if you should freeze zucchini with or without blanching. At the end of the day, it is your choice.

If you decide to NOT blanch your zucchini before freezing, try to use those up within two to three months. Frozen zucchini that hasn’t been blanched tend to discolor a bit when thawed.

Should you peel zucchini before freezing it?

To peel or not to peel, that is the question. Frozen zucchini without the peel tends to be more tender when thawed. If you’re trying to be a sneaky Pete to hide it in recipes like Freezer Spaghetti Sauce, or soups, peeling it first would be best.

Freezing your zukes sliced or as zoodles? Go ahead and leave the skin on.

TOOLS FOR FREEZING Zucchini

How to Freeze Shredded Zucchini

Shred the zucchini using a box grater and place it in a colander. If your grater has different sizes, use the largest option (setting). Pro tip: if you’re shredding a ton of zucchini, use the shredding disc in a food processor

Set the colander in a bowl and let it sit for an hour or up 24 hours (in the fridge). This will allow it to release excess liquid prior to the freezing process.

After it has rested a bit, grab a handful of shredded zucchini, and squeeze to release excess moisture. Repeat until you’ve squeezed all the zucchini in the colander.

Place it on a rimmed baking sheet lined with parchment or a silpat. Gently blot it with clean kitchen towels to absorb any excess liquid.

Spread the shredded zucchini around, but there will still be some clumps no matter how well you spread it around the sheet. Allow it to freeze for 2-3 hours and then transfer to a freezer-safe container.

How to Freeze Zoodles

Spiralize your zucchini (I use this spiralizer) and place it in a colander. Set the colander in a bowl and let it sit for an hour or up 24 hours (in the fridge). This will allow it to release excess liquid prior to the freezing process.

After it has rested a bit, place it on a rimmed baking sheet lined with parchment or a silpat. Gently blot it with clean kitchen towels to absorb excess liquid.

Spread the zoodles around to give them space so they don’t clump up. Allow it to freeze for 2-3 hours and then transfer to a freezer-safe container.

Place on a rimmed baking sheet lined with parchment or a silpat. Allow it to freeze for 2-3 hours and then transfer to a freezer-safe container.

How to Freeze Whole Zucchini

Freezing whole zucchini is best accomplished with small or medium zucchini.  There is no need to blanch whole zucchini prior to freezing.

  1. Thank you for the different ways of freezing zucchini. I would like to share that the overgrown zucchini (baseball bat size)  makes a wonderful  zucchini pineapple. You can find the recipe on Pinterest. I made for my children in the late 70’s. Still works. You think you are eating pineapple. Great substitute. 

  2. I’m definitely freezing garden goodies this year. Just found out Olin probably losing 10 to 20% of my income due to corona. It’s better than a lot of folks out there struggling, but my struggles are real too. It’s going to hurt. 
    I bought some of those silicone bags and to be honest I freaking hate washing them and drying them. I’m afraid they’re not clean and I’ll get salmonella. ???? I might have issues. I love the idea but they kinda scare me. Drying them sucks balls. 

    • We turn them inside out and put them in the dishwasher. And then we let them air dry inside out when they come out of the dishwasher. They’re always nice and clean!

      I’m so sorry about your income loss. This time is so scary and uncertain. It sucks donkey balls.

  3. May I just say how much I LOVE your posts on freezing fruit and vegetables? My freezer is full of goodness to help me over the coming months. I will be praising your name as I have cherries and strawberries in December and January, along with other things. Thanks!

    • Awwww, I’m so glad they’re helpful Beth! Honestly, they don’t seem to get a lot of traction with my readers (low comments, low open rates on emails), but I figure I’m slowly building an info library for freezing stuff. Hopefully one day as a collective they find some raving fans. 🙂
