These cheesy zucchini patties are an excellent way to use up that abundance of zucchini from the garden. Serve with a bit of tomato sauce or sour cream dabbed on top.
Combine zucchini, eggs, flour, Parmesan cheese, mozzarella cheese, onion, and salt in a medium bowl. Stir well enough to distribute ingredients evenly.
Heat oil in a skillet over medium-high heat.
Working in batches, scoop tablespoonfuls of zucchini mixture into hot oil and fry until golden brown, about 2 minutes per side.
