Spiralize your zucchini 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).
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.
Freezing Sliced Zucchini
Slice your zucchini into pieces the sizes you think you’ll use them later. Blanch the slices and dry with a clean kitchen towel.
Boil water in a saucepan, and cook the zucchini for 30 seconds.
Use a slotted spoon to remove the zucchini and place in a bowl of ice water. Allow to cool in the water for 3 minutes.
Strain and blot with a clean towel.
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.
Freezing 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).
Set the colander in a bowl and let it sit for an hour or up 24 hours (in the fridge).
After it has rested a bit, grab a handful of zukes and squeeze to release excess moisture. Repeat with the rest of the shredded zucchini.
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.
Freezing Whole Zucchini
Freezing whole zucchini is best accomplished with small or medium zucchini.
You can place them on a baking sheet, freeze until solid (5-6 hours), and then transfer to freezer storage.
Notes
Frozen zucchini will last in a conventional freezer for six months. If you have a deep freeze/stand-alone freezer, you’re safe to keep them in there for up to a year.
