Cut the ends off of each zuccini and peel if desired.
Place one zucchini in the spiralizer and turn the handle to spiralize it. Cut strands to pasta length. Repeat with remaining zucchini.
At this point, the zoodles are ready to cook or use raw. If they will be used in a recipe that does not need extra liquid, lightly salt the zoodles and let them drain in a colander to remove any excess moisture.
