Using the large holes on a box grater or using a shredding blade on a food processor to shred the zucchini. Place zucchini in a tea towel or piece of cheesecloth and squeeze out as much liquid as possible, twisting the towel to help ring out the liquid.
Shred the onion with the box grater or food processor.
Add zucchini, onion, corn, and egg to a large mixing bowl. Mix well to fully combine.
Add garlic, lemon zest, chives, dill, and salt to the zucchini mixture and stir to combine.
Stir in the flour and cornmeal. Mix well to form a thick batter.
Heat a large skillet over medium high heat, and add enough oi to just coat the bottom of the pan.
Spoon heaping tablespoons of batter into the hot skillet, making sure not to crowd the pan. Fry on one side until golden brown, about 3-4 minutes; flip and cook for another 3 minutes.
Transfer to a paper towel lined baking sheet and sprinkle with salt. Serve warm.
Notes
Make sure to squeeze the liquid from the zucchini, or the batter could wind up being too thin. If it is too thin, add more flour, but know that this could alter the taste and texture.Leftovers should be refrigerated for up to 3 days, or wrapped and frozen for up to 3 months.To reheat, pan fry in a little bit of oil, covered, at medium heat. Or bake or air fry at 350℉ for 4-5 minutes or until heated through.
