Wash the zucchini and cut the ends off. Cut the zucchini into match sticks. I like to cut them about 2 inches long by ½ inch wide. If you have a mandolin you can use that to make life easier, but be very careful when cutting.
Place the cut zucchini on a paper towel and sprinkle with salt. Allow the zucchini to rest for 5 minutes. This process will draw any excess liquid from the zucchini so they are not mushy.
Take out three bowls. Add the flour to one bowl, the eggs to another, and the breadcrumb and parmesan to another. Beat the egg.
While the zucchini rest, get a large pot or a Dutch oven and fill it halfway with oil. Depending on the size of your pot will depend how much oil you need. I found that 4 cups of oil was plenty. You want the oil to be about 3 inches up the side of the pot.
Heat the oil to 350 degrees. Have a candy thermometer in the pot to control the temperature of the oil.
Take another paper towel and pat off any excess liquid that may have accumulated on the zucchini. Take a zucchini and coat it in the flour. Then coat it in the egg mixture, and then coat it in the breadcrumbs. Continue this process until you have about 20 pieces breaded.
When the oil hits 350 degrees, carefully place the zucchini on the spider strainer and place them in the oil. Cook them for 3 minutes on both sides until golden brown.
Remove the zucchini fries from the oil and place them on another paper towel lines plate. Sprinkle with salt and serve as soon as they are cool enough to enjoy.
