Cook the Rice: Rinse the rice well, then cook it according to the package instructions, using 300 ml of water. Once cooked, set the rice aside to cool.
Prepare the Zucchini: Grate the zucchinis using a coarse grater. Squeeze out the excess moisture using a clean kitchen towel or cheesecloth to prevent the fritter mixture from becoming too soggy.
Mix the Ingredients: In a large bowl, combine the cooked rice, grated zucchini, chopped onion, egg, flour, parsley, salt, and black pepper. Stir until well combined.
Form the Fritters: Heat sunflower oil in a frying pan over medium heat. Take small spoonfuls of the mixture and form them into small patties.
Fry the Fritters: Fry the fritters for about 3-4 minutes on each side until golden brown and crispy. Be sure to flip them carefully to avoid breaking.
Drain and Serve: Once fried, remove the fritters from the oil and place them on paper towels to absorb any excess oil. Serve them hot with your favorite dip or as a side dish.
