We love the moistness of zucchini bread, cookies, and muffins and have frozen grated fresh zucchini for later baking. Here’s how to do it:
We’ve never done anything but grate, extract part of the water, measure, and freeze. The squash seems to last just fine over the winter. Some sites, including governmental ones, recommend steaming your grated squash before freezing to increase the storage life. If you choose to do so, use the method below:
Place a small amount of squash in a steamer basket or sieve, no more than 3/4-inch deep. Bring two inches of water to a rapid boil on the stovetop. Place the squash above the boiling water and place a lid on the pot to capture the steam. Steam for about two inches or until the squash turns translucent. Drain off the excess water and repeat with other batches. Freeze as above.
