If you would like to have grated zucchini ready to go for your favorite recipes in your freezer this is a method to use.
Grate the required amount for a specific recipe then steam it by placing it in a sieve or colander 1-inch deep. Steam it over water for 5 minutes. Steam the zucchini 3 inches above the boiling water and have a lid on the kettle. Cool the zucchini before putting it in a container for freezing. Label the package with the amount you started with.
To freeze, wash and cut zucchini in 1/2-inch slices. Place in boiling water for 3 minutes. Start timing immediately, do not wait for the boil to return. Cool in cold water. Drain and freeze. If you wish to fry it in slices, freeze on cookie sheet and then package frozen. Dip slices in mixture and crumbs or flour before it thaws. For casseroles, freeze cubes or small slices of zucchini.
