No matter the method, start by cleaning your zucchini by washing under running water and removing any damages or blemishes.
Freezing Raw Zucchini
Trim away the stem and blossom end of the zucchini, then slice into 1/4-inch thick slices. Depending on the size of your zucchini, or how you prefer to use your zucchini, you can leave your slices whole, cut again into half moons, or cut a second time to quarter them.
Line a rimmed baking sheet with a silicon baking mat. Then place all of the zucchini slices on the lined baking sheet in a single layer - don't overlap them!
Transfer zucchini to the freezer and flash freeze for 2-3 hours, or until frozen solid to the touch.
Transfer frozen zucchini into a freezer-safe bag, silicon bag, or container. Return to freezer and keep up to 3 months.
Blanching Zucchini to Freeze
Trim away the blossom and stem end of the cleaned zucchini, then slice into circles, half moons, or quarters.
Add zucchini to boiling water and blanche for 3 minutes.
Remove blanched zucchini from boiling water and transfer to an ice bath for a few minutes to stop the cooking process.
When zucchini is cool to the touch, transfer to a clean towel or paper towel and pat dry.
Place the blanched zucchini slices in a single layer on a lined baking sheet and freeze for 2-3 hours, until frozen solid.
Transfer to a freezer-safe bag or container and store in the freezer for 3-4 months.
Freezing Shredded Zucchini
Use a food processor or box grater to grate cleaned zucchini.
Place grated zucchini in a cheese cloth, clean towel, or nut milk bag and wring out all the moisture. Keep wringing!
When zucchini has all extra moisture released, measure it in one cup portions (a pretty standard recipe measurement) and place into a freezer-safe bag.
Smush the grated zucchini flat within the bag, and try to squeeze out all extra air. Label bag with the date and item, then store in the freezer 3-4 months.
