1. Grate the zucchini and squeeze out excess moisture using a clean kitchen towel.
2. In a mixing bowl, combine grated zucchini, flour, egg, Parmesan cheese, salt, and black pepper. Mix well.
3. Heat olive oil in a frying pan over medium heat.
4. Scoop spoonfuls of the mixture into the pan, flattening them slightly with a spatula. Fry until golden brown on both sides, about 3-4 minutes per side.
5. Remove fritters from the pan and drain on paper towels. Serve warm.
