To make the zoodles you can use a vegetable spiralizer such as the Paderno Spiral Vegetable Slicer or a mandolin fitted with a julienne blade although the spiralizer is so much easier and safer. Since zucchini releases a lot of water as it cooks, I use it to my advantage and purposely leave the sauce a little thick. Once the noodles cook and release their liquid (I only cook them 2 minutes TOPS) the liquid from the zucchini thins the sauce and it comes out perfect.
