For the firmest texture, do not skip the salting and drying step, which helps prevent watery zucchini noodles in the pan. Cook the zoodles quickly over relatively high heat and remove them from the skillet as soon as they turn bright green and begin to soften. These noodles make a versatile base for rich keto sauces such as Alfredo, pesto, or meat sauces, and they are best enjoyed immediately after cooking. Leftovers can be stored in an airtight container in the refrigerator for up to one day, but expect the texture to soften slightly when reheated in a skillet over medium heat.
