Place the grated zucchini in a clean kitchen towel or cheesecloth and squeeze out any excess moisture. This helps ensure the fritters aren’t too watery.
- In a large mixing bowl, combine the grated zucchini, chopped onion, feta cheese, eggs, dill, mint (if using), flour, salt, pepper, and baking powder. Mix until well combined. The mixture should be thick but sticky enough to hold together.
- Lightly dust your hands with flour and form the mixture into small patties, about 2-3 inches in diameter.
- Heat olive oil in a large frying pan over medium-high heat.
- Fry the zucchini patties in batches, making sure not to overcrowd the pan. Fry for 2-3 minutes on each side, or until golden brown and crispy.
- Remove the fritters from the pan and place them on a paper towel-lined plate to absorb excess oil.
- Serve hot with tzatziki or Greek yogurt for dipping.
