If you think your zucchinis are very watery, drain excess water before cooking them. To do so, cut the zucchini as desired, then arrange them on a baking sheet lined with kitchen paper, sprinkle them with a few pinches of salt, and wait 15 to 30 minutes for the salt to drain the water out of the zucchini. Pat the zucchini dry with kitchen paper and process with the recipe.
