Cut off the stem of each zucchini. Then take a sharp knife and make a vertical cut halfway into each zucchini. When you begin spiralizing your zucchini, this will create noodles that are cut into bite size strands instead of one continuous strand of noodle from each zucchini.
Use the spaghetti noodle blade on a spiralizer. Stick the cut end of your zuchinni into the blade side and the other end into the prongs. Push the zuchinni firmly into the pronged area so that the zucchini is secure when spiralizing. Also, make sure the spiralizer is suctioned tightly to your countertop.
As the noodles come out of the spiralizer put them in a colander sitting over a bowl or in the sink. When all the zucchinis have been spiralized, sprinkle on ½ teaspoon of salt and using your hands distribute the salt to all of the noodles. Let this sit for about 10 minutes.
Add the oil to a frying pan and bring the heat to medium. Add the noodles and remaining salt and cook for 2 minutes. Put the noodles back into the colander over a bowl. Using a wooden spoon, press down on the noodles to press out the water similar to how you would remove the water from frozen spinach. You should collect quite a bit of water in the bowl. Now take a paper towel and pat them dry, then put them into your serving bowl and add your heated sauce of choice. A thick sauce works the best with zucchini noodles.
