Grate zucchini on a box grater, on the side with larger holes, and transfer grated zucchini into a mesh bag or cheese cloth. Squeeze out as much liquid as you can.
Transfer squeezed zucchini into a mixing bowl and add remaining ingredients. Mix well until all ingredients are thoroughly incorporated.
Preheat a large cooking pan over medium heat and lower the temperature a little bit. Add oil and use an ice cream scoop (or a smaller scoop) to scoop out even amounts of zucchini mixture. Gently shape the fritters with your hands and place into the cooking pan.
Cook for 4-6 minutes on each side, depending on the size of the fritters. Try to only flip once so there is less chance of them breaking apart.
Note: if cooking more than one batch of fritters at a time, you many need to add a little more oil to the pan between batches.
