Start by grating the zucchinis. Place them in a clean kitchen towel and squeeze out excess moisture. This will prevent the fritters from being soggy.
In a large mixing bowl, combine the squeezed zucchinis, ricotta cheese, flour, Parmesan cheese, eggs, lemon zest, lemon juice, baking powder, garlic powder, salt, and pepper. Mix until well combined.
Heat a non-stick skillet over medium heat and add a drizzle of olive oil.
Using a spoon or ice cream scoop, drop spoonfuls of the fritter mixture into the skillet. Flatten them slightly with the back of the spoon.
Cook for about 3-4 minutes on each side, or until golden brown and crispy. An optimal indicator is a nice, golden-brown crust forming.
Transfer the cooked fritters to a paper towel-lined plate to absorb any excess oil while you continue cooking the rest of the batch.
Garnish the fritters with fresh chopped parsley before serving.
Notes
Serve warm with sour cream or lemon-garlic yogurt sauce.
