In a colander, sprinkle your shredded zucchini with salt and let sit for 10 minutes. With clean hands, soak out as much of the water from the zucchini and place on a plate, lined with a sheet of paper towel.
In a medium-sized bowl, mix together eggs, flour and parmesan cheese. Add zucchini and mix until all ingredients are well-combined.
Line another plate with a sheet of paper towel and over medium-heat, heat a nonstick pan with olive oil.
Once hot, scoop 1/4 cup of the zucchini mixture into the pan and fry for about 2 minutes. Flip over and fry for another 2 minutes and place on your lined plate.
In a separate bowl, mix together sour cream and garlic powder. This will be your dipping sauce for your fritters.
