01 - Place the grated zucchini in a colander and sprinkle with 1/2 teaspoon salt. Let stand for 10 minutes to extract excess moisture.
02 - Squeeze the zucchini thoroughly using a clean kitchen towel or your hands to eliminate as much liquid as possible.
03 - In a large bowl, mix the drained zucchini with spring onions, minced garlic, eggs, flour, Parmesan cheese, parsley, baking powder, black pepper, and oregano until a thick batter is achieved.
04 - Warm olive oil in a large nonstick skillet over medium heat until shimmering.
05 - Scoop approximately 2 tablespoons of batter per fritter into the pan, flatten gently with a spatula, and cook for 3 to 4 minutes on each side until golden and crisp.
06 - Transfer cooked fritters to a plate lined with paper towels. Continue frying the remaining batter in batches, adding more oil if necessary.
07 - Serve fritters hot, optionally with a spoonful of Greek yogurt or tzatziki on the side.
