Grate the zucchinis using a box grater. Place them in a clean kitchen towel and squeeze out excess moisture.

In a large mixing bowl, combine the grated zucchini, flour, Parmesan cheese, minced garlic, egg, salt, and pepper. Mix until all the ingredients are well incorporated and form a thick batter.

In a non-stick skillet, heat about 1/4 inch of olive oil over medium heat until a small droplet of batter sizzles upon contact.

Using a tablespoon, scoop out some batter and carefully drop it into the hot oil, flattening it slightly with the back of the spoon. Fry for 3-4 minutes on each side or until golden brown.

Transfer the bites to a paper towel-lined plate to absorb excess oil. Serve warm with your favorite dips or enjoy them plain.
