Wash zucchini and trim off ends. Grate on the large holes of a box grater. Place the grated zucchini in a large mixing bowl, stir in 1 tsp salt and set aside for 10 minutes.

Add the chopped green onions, garlic, flour, parmesan and eggs to the zucchini mixture. Season with 1/2 tsp salt and 1/2 tsp black pepper. Stir until well combined.

Place a large heavy bottomed cast iron or non-stick skillet over medium-high heat. Add 2 Tbsp olive oil. Once the oil is hot, add the zucchini mixture a heaping tablespoon at a time (or use an ice cream scoop to create equal size fritters) and flatten out the tops slightly to make them pancake shaped. Sauté 3-5 minutes per side or until golden brown. Serve warm with a dollop of sour cream. Enjoy!
